Hardware Manual Version 7.15 http://www.servelec-semaphore.com/ Page 7

1. INTRODUCTION A Kingfisher Plus+ Remote Terminal Unit (RTU) is a highly configurable device that can monitor and control a wide range of equipment.

This manual details the specifications for each type of module, option board, cable and accessory available for use with a Kingfisher Plus+ Modular RTU.

There are three types of Kingfisher Plus+ modular RTUs identified by the processor module they contain: PC-1, CP-12 or CP-30.

PC-1 CP-12 CP-30

Modular RTUs support up to 64 modules and 1008 IO (input/output) points. Each modular RTU has at least one backplane, a power supply and a processor module.

A PC-1 RTU is powered using an external AC/DC power supply. A PC-1 processor module is only used on a BA-4 PLUS backplane (4 slot).

A CP-12 or CP-30 RTU is powered using a power supply module (or modules) and utilizes one of three backplanes: a BA-40 PLUS (4 slot), a BA-6 PLUS (6 slot) or a BA-12 PLUS (12 slot). A Powered Backplane (BP-x-PLUS) can also be used.

IO (input/output) modules can be added to the RTU in any combination as required. To obtain more communications ports, one or more communications modules can be added to the RTU.

2. BACKPLANES

2.1 Overview The purpose of a backplane is to host all Kingfisher Plus+ modules that make an RTU and to allow the processor module to communicate with all other modules within the same RTU. The backplane also distributes power to each module. Some backplanes can be linked together to create an RTU containing up to 64 modules.

There are two families of Kingfisher Plus+ backplanes available:

• BA-x / BA-x-PLUS – passive backplanes that require a power supply module to be installed in one of the slots to make the RTU working. These backplanes range is a flexible solution for creating medium- to large-scale RTUs of any desired configuration.

• BP-x-PLUS – backplanes with an integrated 5 V power converter that require only one external +12 VDC power supply to run the RTU. These backplanes have limited expansion and configuration capabilities and mainly aimed for building small-scale low-cost RTUs.

Seven versions of backplanes are available in total:

BA-4 / BA-4-PLUS 4-slot backplane for use with PC-1 processor module

BA-40 / BA-40-PLUS 4-slot backplane



BP-2-PLUS 2-slot backplane with integrated 5 V power supply



Note: Where the number of slots is not important, the backplanes will be referred to as ‘BA-x-PLUS’ (for all passive backplanes) and ‘BP-x-PLUS’ (for all backplanes with a built-in power supply) further in this document. The part numbers with the ‘-PLUS’ suffix use the green pluggable terminal blocks for the inter-rack data connectors, while the old (will be referred to as ‘BA-x’) backplanes use black crimp connectors (Harwin Datamate M80) for that purpose.

All Kingfisher Plus+ backplanes are designed to be surface mounted. Mounting brackets (2 pieces) are supplied for user fitting. The backplanes can also be mounted in a 19" rack (see “Accessories” chapter for details).




2.2 BA-x-PLUS Backplanes

2.2.1 BA-4-PLUS: 4-slot Backplane for PC-1 Processor A BA-4-PLUS backplane is designed to be used with a PC-1 power and processor module. The PC-1 is installed into the leftmost slot and any other modules can be installed in the remaining 3 slots.

Please use a BA-40-PLUS backplane if requiring a 4-slot backplane for use with a CP-xx processor and a PS-xx power supply.

BA-4-PLUS backplane




2.2.2 BA-40-PLUS: 4-slot Backplane A BA-40-PLUS backplane is identical to a BA-4-PLUS backplane but with the J6 Power Connector and the PC-1 Power Connector are removed.

This backplane is designed to be used with a PS-xx power supply and a CP-xx processor module or linked to any other backplane to provide additional slots.

BA-40-PLUS backplane




2.2.3 BA-6-PLUS: 6-slot Backplane A BA-6-PLUS six-slot backplane is designed to support any power supply, IO or communications module in any slot position. This backplane is intended to be used with a PS-xx power supply and a CP-xx processor module or linked to any other backplane to provide additional slots.

BA-6-PLUS backplane




2.2.4 BA-12-PLUS: 12-slot Backplane A BA-12-PLUS twelve-slot backplane is designed to support any power supply, IO or communications module in any slot position. It is intended to be used with a PS-xx power supply and a CP-xx processor module or linked to any other backplane to provide additional slots.

BA-12-PLUS backplane




2.3 BP-x-PLUS Backplanes BP-x-PLUS backplanes are available as two-, four- and six- slot versions (BP-2-PLUS, BP-4-PLUS and BP-6-PLUS correspondingly).

The BP-x-PLUS backplanes serve the same purpose as the BA-x-PLUS backplanes, the main difference is that these backplanes have an integrated 5 VDC / 5 A power converter on board and, as a result, do not require a PS-xx power supply for the RTU to work. In order to operate, the BP-x-PLUS backplanes need only be powered from a single external 12 VDC power source. If a backup power source is required then a 12 V lead-acid battery can be connected in parallel with an input power supply with its output adjusted to 13.8 V level. The BP-x-PLUS backplanes do not provide any battery charging means by themselves.

BP-2-PLUS backplane




BP-4-PLUS backplane

BP-6-PLUS backplane




The BP-x-PLUS backplane provides switchable 12VAUX output for powering extra circuits (e.g. an external radio) with its voltage derived directly from the BP-x-PLUS input and therefore not regulated. The output is in ON-state by default and can be controlled by the Toolbox software or user logic (implementation pending).

The status of BP-x-PLUS power rails is indicated by corresponding LED indicators shown on the figure below.

BP-x-PLUS LED Indicators

5V-rail status (top row of LEDs):

• Green (left) LED — 5 VDC power is normal. • Red (right) LED — 5 VDC level is out of range due to overload or circuit fault.

12VAUX-rail status (bottom row of LEDs):

• Green (left) LED — 12 VDC AUX power is turned ON and is normal. • Red (right) LED — 12 VDC AUX level is out of range due to overload or circuit fault. • Both LEDs OFF — 12 VDC AUX power is turned OFF.

The BP-x-PLUS backplanes offer the following protection features:

• Input is protected from overvoltage and reverse polarity (crowbar protection level set to 18 VDC), and from overcurrent (a polyfuse rated at 6 A @ 25 °C).

• 5 VDC output is protected from overload (5 A maximum output current).

• 12 V AUX output is protected from overload (2 A maximum output current).




Note that the crowbar protection circuit will latch when its voltage is either below -0.5 V or above +18.5 V (approximately). It will clamp the input power rail voltage to a very low value: ± (0.5 – 2.5) V depending on the clamp current supplied by a power source. If the power source can provide current exceeding a polyfuse trip current (3-24 A depending on the ambient temperature), it may trip also, limiting the clamp current to several milliamperes.

To recover protective circuit after tripping, the input voltage should be removed completely. A 5-10 s pause before re-applying input power may be required to allow for the polyfuse to cool down if it has tripped.

WARNING. Install BP-x-PLUS as close to the power source as practically possible. To avoid tripping of the overvoltage / reverse polarity protection circuit, that may occur due to voltage overshoots caused by the parasitic inductances of the long wires, the power wires length should not exceed 3 m. Install a 330 - 1000 µF (rated 25 V minimum) capacitor as close as practical to the input power terminals of the BP-x-PLUS backplane if high levels of electromagnetic interferences may be present at the installation site.

There are no adjustable or serviceable parts on the BP-x-PLUS backplanes. Since these backplanes are not configurable, their rack number is always fixed to #1 and their slot numbering always starts from 1. Therefore, only one BP-x-PLUS backplane can be used in the RTU. However, Power and/or Data Connectors to extend the RTU using BA-x-PLUS backplanes are available.

Block-diagram of the BP-x-PLUS backplanes is shown in the figure below.

BP-x-PLUS 5V Output Derating Curve

The BP-x-PLUS backplanes are fully compatible with all other Kingfisher Plus+ modules except Power Supply units (PS-xx). Although accidental installation of PS-xx module into a powered backplane will not cause any damage, this is not recommended as the BP-x-PLUS modules are intended to supply power independently and not designed to share power with other power sources.




2.4 Connectors There are several connectors located at the right-hand side of the Kingfisher Plus+ backplanes which are used for wiring power and/or signals outside of a backplane. The type and quantity of the connectors depend on the model of the backplane. Please refer to the pictures of the backplanes shown earlier in this chapter and/or the connector reference designators to determine which connectors exist on your backplane. All connectors are described in the table below.

It is recommended to cover all unused backplane connectors in harsh environmental conditions (e.g. by fitting the mating connector). The parts suitable for the Power and Data connectors are listed in the table above. The suitable mating parts for the 32-pin module slot connectors are listed below:

1. Oupiin P/Ns: 9001-3532 / 9001-3520 / 9001-3732 / 9001-3720.

2. Harting P/Ns: 09 22 132 7922 / 09 22 132 6922 / 09 22 132 2922 / 09 22 132 7921 / 09 22 132 6921 / 09 22 132 2921.




2.5 Linking Backplanes

2.5.1 Creating Racks A single RTU can consist of up to 64 modules by using a six-bit number adopted in the Kingfisher Plus+ systems:

In order to organise connection of up to 64 modules into one RTU, backplanes should be linked together into ‘racks’. Each rack can have a maximum of 16 slots. A single RTU can support up to 4 racks thus providing a total of 64 module slots.

The figure below shows one full rack (16 slots) consisting of a BA-40-PLUS linked to a BA-12-PLUS.

The BA-x-PLUS backplanes have an IN and an OUT connectors (J13 and J15 described earlier) linking them to the RTU data bus. The BP-x-PLUS backplanes have only one (OUT) connector linking them to the RTU data bus (J13). The reason for this is that the BP-x-PLUS backplane must always be the first in an RTU.




2.5.2 Backplane Cables While building an RTU, it may become necessary to organise signals and/or power connections between backplanes. To implement the required interconnections the cables will be required that can be either assembled (based on the data on the backplane connectors provided above) or ordered from your Kingfisher supplier. The following cables are available for order:

2.5.3 Setting Bus Terminators Each BA-x-PLUS backplane has data bus terminators (resistors) that can be Enabled or Disabled by the first six switches of the DIP-switch installed on the backplane PCB (please refer to the information printed on the backplane board surface for exact details on possible switch configurations). A chain of backplanes requires the terminators to be switched ON (Enabled) for the first and the last backplane in the chain. All intermediate backplanes must have terminators switched OFF (Disabled). The BP-x-PLUS backplanes have their terminating resistors always enabled as they are designed to be the first backplane in a rack.

IO-bus terminators control switches CM-bus terminators control switches

2.5.4 Setting Rack Number While the rack number value of the BP-x-PLUS backplanes is always fixed (and equal to #1), the BA-x-PLUS backplanes allow that their rack number to be configured with the switches #7 and #8 of the on-board DIP-switch (please refer to the information printed on the backplane board surface for exact details on possible switch configurations).

Rack Number control switches

The following table outlines the DIP switch configuration required for the most recent hardware revisions of the BA-backplanes (v2.x and v3.x). For previous hardware versions please refer to the Superseded Products manual available on Semaphore Helpdesk.

Backplane Switch Configuration Example (revision 2.x and 3.x):

Note that supplementary to the data bus connections shown, each backplane requires either a Power Supply Module installed or a power cable connected to J14.

For previous backplane hardware revisions please refer to the Superseded Products Manual.




2.5.5 Setting Slot Number Range Backplanes have hard-coded slot numbers which, for the BA-x-PLUS modules, can be set to four different ranges determined by the rack number (please refer to the ‘Setting Rack Number’ section of this chapter for details). The BP-x-PLUS backplanes slot numbering range is not configurable and always starts from #1.

The BP-x-PLUS, BA-6-PLUS and BA-12-PLUS backplanes occupy the start of each rack, while the BA-4-PLUS (and BA-40-PLUS) occupies the last four slot numbers in each rack (e.g. #13 to #16 in Rack 1). Starting from v3.3, the BA-4-PLUS / BA-40-PLUS backplanes can be used in the beginning of the rack as well. To achieve this, the BA-4-PLUS / BA-40-PLUS backplanes are equipped with an extended 10-way DIP-switch. Switches #9 and #10 are used to configure the desired slot numbering range (see the figure below for possible switch configurations).

Slots numbered from 1 to 4 (for Rack 1) Slots numbered from 13 to 16 (for Rack 1)

Slot Number Range control switches (BA-4-PLUS & BA-40-PLUS only)

The configuration when both #9 and #10 switches are turned ON (factory default setting) is equal to the left picture above (Slots are numbered from 1 to 4 for Rack 1) but increases current consumption from the 5V rail by 3 mA approximately. The configuration with both #9 and #10 switches turned OFF should not be used as the slot numbering setting becomes undefined.

An example of the possible RTU configuration, explaining rack and slot numbering sequence, is shown on the picture below.




3. POWER SUPPLY MODULES

3.1 Overview The Kingfisher Power Supply Modules allow real time monitoring of currents, voltages and temperatures supplied to the RTU and the backup battery. The monitoring capability also allows the RTU to determine when a supply has failed if in a redundant configuration.

If fitted, auxiliary supplies can be overridden manually or by logic to allow for external equipment or sensor loops to be shut down or reset.

3.2 PS-x2 and PS-x1 Power Supply Modules

3.2.1 Overview • Monitoring of rail voltages, supply & battery currents and temperature • AC or DC input • Support for redundancy (several supplies per backplane) • Isolated DC output • Sealed Lead Acid battery connection with charging/monitoring and low voltage

protection • Software controlled power to the Backplane and Aux Outputs

Note: PS-x1 is a SUPERSEDED product and is not being manufactured currently.

Avertissement de Sécurité

Le terminal de terre à l’entrée de l’alimentation secteur est uniquement une connexion de TERRE FONCTIONNELLE.

On ne peut pas compter sur lui pour assurer la sécurité.

The PS-x2/PS-x1 modules provide AC-DC (PS-12 and PS-11 only) or DC-DC conversion from mains power into 12 VDC and 5 VDC for the backplane, as well as 12 VDC and optional 24 VDC auxiliary outputs. Both auxiliary outputs can be controlled by the RTU logic configuration.

The PS-x2/PS-x1 is supplied with an internal temperature sensor to monitor its PCB temperature and an optional external temperature sensor to monitor a backup battery. When the battery is connected, the supplied external sensor should be mounted in the vicinity of the battery negative terminal to ensure correct temperature compensation. If readings from the external temperature sensor are out of range, internal sensor data is used. Boost charge is disabled when external temperature sensor is faulty, not connected or if the battery temperature is out of range. Please note the charge circuitry is designed for float operation and short term boost of batteries already charged and in good condition. Use of this supply on flat or fully discharged batteries may cause damage to the module.

The 12V Rail Voltage, Supply Current, Battery Current, internal and, optionally, external temperature monitoring circuits, various status and controls registers enable the RTU to monitor and to control all functions of the PS-x2/PS-x1 module. The Processor Module has access to many of these values as analogue and digital points in the system.

If the Mains power interrupted and the system is powered from the backup battery, the PS-x2/PS-x1 enters Low Battery Shutdown when battery voltage drops below 10.6 V. All outputs are switched OFF for battery preservation, including Backplane power as well – effectively meaning that the whole RTU will be shut down. PS-x2/PS-x1 switches itself to the lowest power consumption mode possible, further preserving the battery from deep discharge. PS-x2/PS-x1 checks rail voltage regularly, and the Backplane power will be restored when +12V_RAIL voltage rises above 12.4 V (if no Mains present) or 11.2 V (if Mains present).

Besides various hardware protection features, PS-x2/PS-x1 firmware provides additional protection from overload. If output power exceeds its maximum specified power, the Switch-mode Power Supply (SMPS) will enter an Overload Mode. Its output voltage will be ramped down and, if overload still persists when it reaches 10.0 V (minimal output voltage), it will switch all outputs off, similar to Low Battery Shutdown. PS-x2/PS-x1 will attempt to switch the Backplane ON again regularly. RTU power will be restored permanently when overload condition is removed.

Several Power Supply modules of any type can be installed on a backplane thus providing redundant and alternative power source configurations.

PS-x2/PS-x1 modules can be swapped while RTU is running, providing that there is an alternative power source in the system for the RTU to be powered during such swap – e.g. another (redundant) PS-xx module.




3.2.2 Options and Ordering Info Since PS-x1 modules are superseded, this section does not contain ordering information for PS-11 and PS-21 modules.

Unless explicitly noted, all hardware versions of PS-x2 modules are described in this manual. The newer PS-x2 version (v1.5) has some differences in the module features and specifications comparing with its predecessor (v1.3); in particular the available current for the 5V rail has increased from 3 A to 5 A and the operating temperature range has been extended to -40 °C to +85 °C.

The PS-x2 modules with ‘-C’ suffix in their Order Code have an additional isolated DC-DC converter board DC-10 installed / plugged in to the main PS-x2 board. It provides isolated 24 V power to the 24VAUX output.

PS-x2 options, ordering info and main specification differences are summarised in the table below:

3.2.3 Theory of operation A combined block-diagram of the PS-x2 and PS-x1 modules is shown on the picture below.

PS-x2/PS-x1 Block Diagram

When Mains power is supplied to the SMPS, it generates a DC output voltage on the internal +12V_RAIL of the PS-x2/PS-x1. Voltage level on this rail is controlled by the microcontroller (MCU). Supply Current Sensor is used to measure current supplied by the SMPS.

When 12VBP SWITCH is activated, power from the internal rail is fed to the backplane and to the 5VBP converter that powers 5VBP rail on the backplane, providing power to all modules installed there. Both 12VBP and 5VBP outputs are connected to the backplane outputs via ideal diodes that allow for redundant connection of the PS-x2/PS-x1 modules.

24VAUX ISOLATED Converter (option ‘-C’ only) and 12VAUX SWITCH can be switched ON and OFF with user logic, providing power to the corresponding outputs of the field connector as required.

Any device connected to the ‘B’ terminals of the Field Connector (J22 for PS-x2; ), including a battery, is connected directly to the internal +12V_RAIL of the PS-x2/PS-x1. Battery Current Sensor is used to measure current flowing to or from ‘B’ terminals. Assuming that a battery is connected to these terminals, positive current flows into the battery when it is charged and negative current flows out of the battery when it supplies power to the RTU.

The PS-x2/PS-11 battery input has a crowbar protection circuit with series polyfuse to protect it from over-voltage and reverse-polarity connection. The crowbar protection circuit will latch when its voltage is either below -0.5 V or above +18.5 V (approximately). It will clamp the input power rail voltage to a very low value: ± (0.5 – 2.5) V depending on the clamp current supplied by a power source. If the power source can provide current exceeding a polyfuse trip current (2-16 A depending on the ambient temperature), it may trip also, limiting the clamp current to several milliamperes. To recover protective circuit after tripping, the input voltage should be removed completely. A 5-10 s pause before re-applying input power may be required to allow for the polyfuse to cool down if it has tripped.




3.2.4 Battery Charging PS-x2/PS-x1 power supply modules are designed with provisions for the backup battery charging and monitoring. They can charge 12 V Sealed Lead Acid (SLA) batteries with the capacity from 6 Ah to 25 Ah connected to the ‘B+’ and ‘B-’ terminals. SLA batteries of higher capacity or unsealed (wet) lead-acid batteries can be used if required but the PS-x2/PS-x1 will not be able to fully charge them and to maintain / properly calculate its internal charge level (required for making correct decisions by charging control algorithms). As a result, their performance cannot be guaranteed.

When more than 100 mA is drawn out of (or is supplied to) ‘B’ terminals (e.g. when a battery is connected), the PS-x2/PS-x1 logic assumes that a fully discharged battery has just been connected and starts its Boost charge. Boost charge is not possible if external temperature sensor is not connected, or it is faulty, or when battery temperature is below -20 °C or above +60 °C. After boost charging the battery for the estimated time (3-10 hours, BATT DET and BATT BST LEDs ON, see below for details), the power supply will switch to Float charging (BATT DET and BATT FLT LEDs ON).

PS-x2/PS-x1 maintains an estimated charge level of the attached battery and this value is used for making a decision for switching to the Boost charge when the battery charge level drops below 40% of its nominal capacity. For this algorithm to work properly, a correct battery capacity should be provided to the PS-x2/PS-x1 via the Toolbox / RTU configuration setup. When battery is initially detected, it is assumed to be fully discharged. Boost charging time mentioned earlier is calculated based on the provided battery capacity value. Estimated battery charge level is increased by integrating measured charge current flowing into the battery over the time till it reaches the stated battery capacity. When battery current becomes negative (for instance, if Mains power is out and the RTU runs from the battery), this current is integrated over the time and subtracted from the estimated battery charge level till it reaches zero.

Please note that PS-x2/PS-x1 is not able to distinguish between the real battery connection and the connection of any other (generic) load or power source to the battery terminals, as it detects such connections only by measuring the Battery Current. As a result, all battery status related LEDs may exhibit several various patterns depending on kind of load / source connected to the ‘B’ terminals.

3.4.3 Total Power Load The total current required to power the RTU is as follows:

𝐼𝐼𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇 𝐿𝐿𝑇𝑇𝑇𝑇𝐿𝐿 = 𝐼𝐼𝑃𝑃𝑃𝑃𝑇𝑇𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑇𝑇𝑃𝑃 𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇 + 𝐼𝐼𝑀𝑀𝑀𝑀−𝑥𝑥𝑥𝑥 𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇 + 𝐼𝐼𝐼𝐼𝐼𝐼 𝑀𝑀𝑇𝑇𝐿𝐿𝑀𝑀𝑇𝑇𝑃𝑃 𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇 Total Power load is therefore:

𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇 𝑃𝑃𝑇𝑇𝑃𝑃𝑃𝑃𝑃𝑃 [𝑊𝑊𝑇𝑇𝑇𝑇𝑇𝑇𝑊𝑊] =13.8 [𝑉𝑉] × 𝐼𝐼𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇𝑇 𝐿𝐿𝑇𝑇𝑇𝑇𝐿𝐿 [𝑚𝑚𝑚𝑚]

1000

• The Total Current Load for a PS-12/22 should not exceed 4.5 Amps. • The Total Current Load for a PC-1 should not exceed 4 Amps. Loads greater than 4

Amps will require a PS-12/22 supply to be installed. • Users should be mindful of the current draw on the 5 VDC rail. See the “5 V Rail

Overload Check” chapter for more details.

3.4.4 Battery Backup To maximise the service life of the battery, the depth of its discharge should not exceed 50% of available capacity. E.g. for a 7 Ah battery, there is 3.5 Ah of backup power. Therefore the battery can supply 3.5 Amps for 1 hour or 1 Amp for 3.5 hours etc. The size of the backup battery required depends on how long the RTU needs to be able to run without mains power. In addition to the Total Current Load above, a backup battery will also need to power the PS-12/22 if present (not applicable if using a PC-1 processor).




4. PROCESSOR MODULES

4.1 Overview The processor module is the core part of any RTU. It is responsible for running user logic and facilitating inter-module interactions (via backplane) and communications with the SCADA system and other RTUs and various 3rd party devices (via communications ports) as required. The amount of memory, speed, and flexibility of an RTU is determined by the processor module selected.

There are three processor modules available in the Kingfisher Plus+ modular RTU range. Each of them has one resident communications port, with an ability to add up to two additional communications ports as.

4.2 PC-1: Power & Processor Module

4.2.1 Overview • Monitoring of battery and input supplies • Isolated DC Outputs • 16 MHz Processor • DC Input Supply • Up to two communications ports • Low Voltage Battery Protection • 256 KB SRAM

The PC-1 is one of the best supported processors available to a kingfisher RTU. It is well suited to small and mid-size installations as it features an integrated power supply, reduces the system complexity by negating the need for additional power supply modules.

With remote installations in mind the PC-1 was designed to be capable of running from a backup battery, and has a fully isolated low power DC output for external equipment.

To configure the PC-1, a PC running the Toolbox 32 software is required. The Toolbox 32 software allows the user to implement ladder logic.

The PC-1 can only be installed in the first slot of a 4-slot backplane (BA-4) and operates from a nominal +12 VDC supply (typically 13.8 VDC). The module has one fixed RS-232 port and one option port.

A PC-1 has two links that can be accessed from the rear of the module as shown below.

The SRAM battery is enabled at shipping time by the factory. The user can clear the SRAM by removing the SRAM link for five minutes. This will clear the RTU configuration and ladder logic.




4.2.2 Part Numbers The PC-1 is available with 3 options (A, P, M) as detailed below.

4.3 CP-12 Processor Module

4.3.1 Overview • Support for Processor and Communications Redundancy • Up to 3 communications ports • 40 MHz x86 CPU

The CP-12 processor module has up to three independent communications ports. Ports 2 and 3 can house option boards while port 1 is a fixed serial port (RS-232).

This processor is targeted at the application space that is too complex for the PC-1 but does not required the additional features made available with a CP-30 based system. The CP-12 has extended functionality over the PC-1 such as redundant processor and communications modules support, and is compatible with Ethernet based boards.

The CP-12 uses the same configuration software as the PC-1 processor, and as such is programmable with ladder logic.

The CP-12 has 512 KB of flash memory for operating code and system parameter storage, and 512 KB of battery backed SRAM for all configuration and event storage data.

4.3.2 CP-12 Reset Procedures

The SRAM battery is enabled from the factory by default. The user can clear the SRAM by removing the SRAM link for five minutes.

This will clear the RTU configuration and Ladder Logic.

Behind the LED lens of the CP-12 there is a diagonally mounted jumper. This is a hardware feature unique to the CP-12 processor.

When the jumper pins are shorted while the module is being reset (or power cycled), the processor will enter Monitor Mode (the Kingfisher bootloader) and perform a read/write test of the SRAM. This will forcefully clear SRAM, having the same effect as removal of the SRAM link on the back of the CP-12 module.

Monitor Mode is a deterministic and efficient way of clearing a Processor as the module does not need to be removed from the Backplane, and as the SRAM is forcibly overwritten.




Note: The RAM test is extremely fast. The CP-12 will clear the RAM nearly instantly. To exit monitor mode, remove the short and power cycle the unit again.

4.3.3 CP-12 Module LEDs

4.4 CP-30: High Performance Processor Module

4.4.1 Overview • Compliant with IEC-61131 programming languages • Up to 3 communications ports • Supports Communications and Processor Redundancy

The CP-30 is a high performance processor module that can provide exceptional speed, memory and functionality to your RTU.

Targeting large RTU systems, the CP-30 is equipped with a 166 MHz ARM9 CPU, capable of running all IEC-61131-3 certified languages, and utilises an Ethernet port as the default connection and configuration medium.

To configure the CP-30, a PC with an Ethernet port and the Toolbox PLUS+ software is required.

Toolbox PLUS+ features ISaGRAF™ software, which provides logic programming in the IEC-61131 standard languages: Structured Text, Ladder Diagram, Function Block Diagram, Instruction List, Sequential Function Chart and Flow Chart.

The processor module has up to three independent communications ports. Ports 2 and 3 can use plug-in option boards while port 1 is fixed as Ethernet (both 10 Mbps and 100 Mbps modes are supported).

RTUs can use a second CP-30 module to provide processor redundancy. One processor must be installed in an even-numbered backplane slot (the active processor on power up) and the other in an odd-numbered backplane slot (the passive processor on power up). The active processor continuously scans all backplane slots (among other tasks) so that it can detect, control and monitor all other RTU modules. The passive (standby) processor will switch to active mode when it detects that communications on the backplane stopped for longer than a predefined maximum time that may be caused (but not limited to) by:

• Failure, removal or reset of the active processor • Download of the configuration, logic or firmware to the active processor

The CP-30 flash memory is used for the storage of all operating code, RTU configuration and event logs. It also has 32 MB of SDRAM for program operation and general data storage and 128 KB (v1.x) / 512 KB (v2.x) of battery backed SRAM for non-volatile data such as retained variables and system log.

The module is powered from the +5 VDC rail on the backplane.

4.4.2 CP-30 Options and Ordering Info Unless explicitly noted, all hardware versions of CP-30 modules are described in this manual. The newer CP-30 version (v2.3) has some differences in the module features and specifications comparing with its predecessor (v1.6); in particular the amount of battery backed SRAM has increased from 128 KB to 512 KB, a quick reset to factory defaults has been added, the backup battery has been made user replaceable, and the operating temperature range has been extended to -40 °C to +85 °C.

CP-30 options, ordering info and main specification differences are summarised in the table below:

4.4.3 Backup Battery / Reset to Factory Defaults CP-30 modules include lithium coin backup battery for Real Time Clock operation and for preserving content of the battery backed SRAM when power is removed from the module.

Backup battery on v1.x is soldered to the PCB assembly of the CP-30 module. A battery retainer is used on v2.x, allowing the user to replace the battery without any special tools.

CAUTION: After removing and re-installing the SRAM link or after replacing the battery, ensure that the CP-30 is powered up for at least 1 s.

This will assure the backup battery functioning for the specified life span.




Battery Backed RAM is connected to the backup battery via SRAM link located on the back of the CP-30 module as shown on the diagram below. The SRAM link is installed at shipping time by the factory.

The user can perform reset to factory defaults / clear the battery backed SRAM. Note. Reset to factory defaults clears RTU configuration and user logic but it will not clear the system log.

To perform reset to factory default using the SRAM link:

1. Remove CP-30 module from the backplane.

2. Remove the SRAM link for at least 5 min.

3. Install the SRAM link back on its header.

4. Install CP-30 on the backplane.

5. Switch backplane power ON (if it was OFF).

An alternative way of resetting the module to factory defaults has been added to the CP-30 v2.x hardware. It allows performing a quick reset to factory defaults:

1. Switch off power to the corresponding RTU rack.

2. Short together pins of the 2-pin header (located underneath LED display, on the front edge of the module) using a jumper link or another suitable conductive object (e.g. a metal screwdriver, ball-point pen, etc.).

3. Keeping the pins shorted, turn on the RTU power.

4. The short can be removed any time after that.

WARNING. Follow Anti-Static Procedures to avoid permanent damage to the circuit board components.

CP-30 v2.x modules allow for a backup battery to be replaced by the user:




1. Obtain (purchase or order from Semaphore) a new battery. WARNING. Only CR2450N batteries from Renata are specified for operating temperature range from -40°C to +85°C.

2. Disassemble the CP-30 module and pull the PCB out from enclosure as per ‘Installing

and Removing Option Boards’ (steps 1 to 5). WARNING. Follow Anti-Static Procedures to avoid permanent damage to the circuit board components.

3. Remove old battery and safely dispose it of in accordance with your local regulations.

4. Insert the new battery all the way in into the battery holder observing correct polarity (negative terminal of the battery should face PCB surface). WARNING. Inserting battery in reverse polarity may permanently damage CP-30 module.

5. Reassemble the module as per ‘Installing and Removing Option Boards’ (steps 7 and 8).

6.6.2 Connecting a Radio As the port is isolated it is necessary to use an external voltage source (normally from the RTU ‘radio’ connection +12 V) to power not only the radio but also the carrier detect circuit.

Some radios have a very low audio interface level (TX Audio), e.g. Maxon DM 0530, DM-2850, SD-125 and Tait T2010 / 2015. These radios will most likely require a resistor network external to the port to drop the TX Audio level.

Some radios (e.g. Maxon) have an internal pull up resistor to +5 V on the carrier detect line, if +12 V is used on the carrier detect optocoupler and then run to the carrier detect output on the radio, the optocoupler will always be driven. There are several ways to get around this:

1. Use a radio without an internal pull up to +5 V (Trio SR, possibly Tait).

2. Modify the radio by removing the internal pull up, as per manufacturer’s instructions.

3. Use +5 V to supply the carrier detect optoisolation circuit. (DO NOT USE +5 V FROM THE BACKPLANE CONNECTOR AS IT IS NOT ISOLATED).

6.7 Option Board H: HART Interface

The HART option board provides a Bell 202 interface to devices supporting the HART protocol. Each HART option board can communicate with up to 15 Hart devices. Two HART option boards can be installed on the one RTU allowing up to 2 point-to-point circuits or 2 multi-drop circuits.

In a point-to-point installation, the loop current can be measured using an RTU analogue input channel. If using two separate point to point circuits and reading the loop current in each, the RTU analogue input channels must be isolated from each other.

In a multi-drop installation, the loop current is not used or measured.

For more information regarding HART configurations please refer to the “HART Implementation Guide” available on Semaphore Helpdesk.

9. ANALOGUE INPUT MODULES Analogue input modules provide analogue inputs to the Kingfisher RTU.

Each module is equipped with a fully isolated 24 VDC power supply for energizing field equipment such as sensor loops.

9.1 AI-1: 8 Channel Analogue Current Input Module

9.1.1 Overview • 12 Bit resolution • 1.5 kV Field to Logic Isolation • 2 ms scan rate • 24 VDC isolated DC output • 0 – 20 mA or 4 – 20 mA current inputs • 0 – 5 VDC or 1 – 5 VDC Voltage Inputs (requires factory modification)

The analogue input module provides eight input channels, each capable of converting an analogue input signal to a digital variable for use as required by your application. A link on the rear of the module selects 4-20 mA or 0-20 mA for all 8 channels. The default range is 4 to 20 mA.

The module can also be factory modified to handle voltage inputs of 0-5 VDC or 1-5 VDC.

Conversion speed for each of the eight channels is 20 µs and this provides a total update rate of two milliseconds for the module. Resolution of the converted signal is 12 bits binary (1 part in 4096) over the range. The placement of the 12 bits from the A/D converter in the #AI data word is as follows:

LSB MSB

0 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 0 0 0

If the current source is reversed into the input, or is less than the low end of the current range, then the module will output a data word corresponding to the low end of the current range (0000H in #AI). If an input that is out of range is entered (i.e. greater than 20 mA), the A/D converter will output up to full scale (corresponding to 7FF8H in #AI).




Scaling of the input is shown below:

Input protection for the module is sufficient to guarantee operation with reduced performance with up to 1500 V common-mode. The module provides electrical isolation of externally generated noise between field wiring and the backplane through the use of optical isolation.

To minimise the capacitive loading and noise, all field connections to the module should be wired using a good grade of twisted, shielded instrumentation cable. The shields can be connected to GND. The GND connection provides access to the backplane (frame ground).

This module can be installed in any I/O slot of a 4, 6 or 12-slot backplane.

Hot Swap Yes. Module can be swapped while RTU is running. Hot swap will not cause a Warm Start. Inputs are cleared in RTU memory while module is removed.

* Analogue inputs can be modified from current inputs to voltage inputs by lifting one pin (or by the complete removal) of the 250 Ω channel resistor. Each channel has its own resistor, so any combination of channels can be converted. It is recommended that modules be returned to Semaphore for factory conversion if required. No responsibility will be taken by Semaphore for damage caused to boards during modification performed by clients. The circuit board resistors to change are: R9 to R16 (channels 1 to 8 correspondingly).

9.2 AI-10: 8 Channel High Impedance Analogue Input Module

9.2.1 Overview • 16 Bit resolution • 3 kV field to logic isolation • Bipolar differential channels • 24 VDC isolated DC output • AI-10: Current / Low Impedance Inputs • AI-10-V: High Impedance Voltage Inputs • 10 ms (1 ms*) scan rate • Mains noise rejection* * AI-10 hardware version 2.x only.

Unless explicitly noted, all hardware versions of AI-10 modules are described in this section. The newer AI-10 v2.x modules can be recognised by the label on the side which indicates the hardware version. If the version number is not printed on the label then the module is v1.6 or older.

The AI-10-V modules (v1.x only) are identical to the AI-10 modules but have the 250 Ω current sensing resistors disconnected. This increases the input impedance for each channel to more than 1 MΩ which is suitably high for voltage transducers. Each channel has its own current sensing resistor, so any combination of channels can be converted.

In order to modify AI-10 v1.x the current sensing resistors have to be physically disconnected (either by lifting one pin or by complete removal of the resistor). The circuit board resistors to change are: R64 to R71 (channels 1 to 8 correspondingly). It is recommended that modules be returned to Semaphore for factory conversion if required. No responsibility will be taken by Semaphore for damage caused to boards during modification performed by clients.

The AI-10 v2.x has internal jumpers (shorting links) that allow the input to be configured for either current or voltage measurement. If a jumper is installed (default) then the related input is configured to measure current. If a jumper is removed then the related input is configured to measure voltage. Note that the factory fitted jumpers are yellow in colour and of a higher grade than commonly found. Use of other jumpers may result in degradation of measurement accuracy and so should be avoided. Appropriate handling precautions have to be observed to avoid ESD and other damage when removing or installing shorting links.




All AI-10 modules provide: • 8 analogue inputs with high electrical isolation between the field terminals and the RTU

logic. • A 24 V isolated output that can be used to power field sensors / transducers • 16 bit input resolution • Full compatibility with the AI-1 and AI-4 analogue input modules but with enhanced

resolution.

The AI-10 supports various current input ranges as follows: • 0-20 mA • 4-20 mA • ±10 mA1 • ±20 mA1

1 For AI-10 v2.x only unipolar current ranges are recommended for use. Bipolar ranges are not calibrated for current measurement.

The AI-10-V supports various voltage input ranges as follows: • 0-5 V1 • 1-5 V1 • ±2.5 V • ±5 V • ±10 V

1 For AI-10 v2.x only bipolar voltage ranges are recommended for use. Unipolar ranges are not calibrated for voltage measurement.

To minimize the capacitive loading and noise, all field connections to the module should be wired using a good grade of twisted, shielded instrumentation cable. The shields can be connected to ground.

This module consumes power from the +5 VDC and +12 VDC RTU rails. A built-in 24V DC-DC converter is used to provide isolated power to the analogue front-end and can also be utilised to power the field devices if required.

9.2.4 AI-10 / AI-10-V Wiring Diagram The insert in the hinged cover of the terminal strip has circuit wiring information. Circuit identification information can be recorded on the outside surface of the insert.










Loop

* When using the +24 V output to power a transducer, the negative input terminal of the analogue input channel (2, 4, 6, 8, 12, 14, 16 or 18) must be wired to the OV terminal (10 or 20). This will complete the current loop due to electrical isolation between the input channel and the module +24 V Output. Note: Any channels sharing the same power source (e.g. +24 V from module or a field power supply) are no longer isolated from one other.




10. ANALOGUE OUTPUT MODULE The AO-3 analogue output module provides four 12-bit current loop outputs allowing a Kingfisher RTU to drive analogue loads.

10.1 AO-3: Analogue Output Module

10.1.1 Overview • 12 bit resolution • 3 kV field to logic isolation • Open loop detection • 0 – 20 or 4 – 20 mA outputs • 3 kV channel group to channel group isolation

The AO-3 provides four current output channels that use 12-bit digital to analogue converters (DAC). The AO-3 also provides open loop detection.

The sign bit is not used in the digital to analogue conversion process. The placement of the 12 bits within the data word is as follows:

LSB MSB

0 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 0 0 0

This module provides two output ranges. The default range is 4 to 20 mA with user data scaled so that a count of 0 corresponds to 4 mA and a count of 32760 corresponds to 20 mA. A range link (on the rear of the module) selects either 4-20 mA or 0-20 mA for all four channels. The default condition is 4-20 mA with the link on. The module provides 12 bits of resolution in either range.

Scaling of the output is shown below.




Analogue outputs 1 & 2 and analogue outputs 3 & 4 form two groups that are isolated from each other and from the backplane logic. Each group is powered by a separate DC-DC converter module that produces an isolated voltage of +24 V to drive the current loop outputs and analogue front-end.

The current loop drivers on the module are source type drivers. To minimize the capacitive loading and noise, all field connections to the module should be wired using a good grade of twisted, shielded instrumentation cable. The shields should be connected to E (Shield) on the user terminal connector block. The E connection provides path to the backplane (frame Earth / Ground) resulting in attenuation of noise caused by the shield drain currents. To further improve noise immunity, direct connection of the analogue cable shields to the Earth / Ground rails with metal clamps or similar method is recommended, especially in environments with high electromagnetic noise levels.

This module can be installed in any I/O slot of a 4, 6 or 12 slot backplane in a system. Up to 10 Analogue output modules can be installed on a single 12-slot backplane.

11.2 DI-5: DC Input 16 Channel Digital Input Module

11.2.1 Overview • Pulse counting on channels 1 to 4 (up to 10 kHz) • Positive or Negative Polarity Inputs • Isolated DC Outputs for powering inputs

The DI-5 provides 16 input channels with one common. As a wide input voltage is accepted a wide range of input devices can be used such as buttons, reed switches, line switches, PIR sensors, and proximity sensors. Any combination of inputs powered externally or by the modules own isolated DC supply (+12 V) can be used.

Applying a high input voltage results in logic 1 in the modules status register. Low (or not present) input voltages result in logic 0.

The DI-5 counter can also count pulses in the first 4 digital inputs. It is able to count up to 10 kHz on inputs 1 and 2 and can count up to 255 Hz on inputs 3 and 4. The pulse total and the frequency for each of the first 4 digital inputs are stored.

This module can be installed in any I/O slot of a 4, 6 or 12 slot backplane system.

11.3 DI-10: AC or DC Input, 16 Channel

11.3.1 Overview • Frequency/Pulse/Quadrature counters on up to 7 inputs/pairs • Isolated DC Field Power Output • Software Debounce • AC or DC Inputs • Sequence of events recording (with optional GPS time synchronisation) • Hot Swappable

The DI-10 provides 16 AC or DC input channels allowing it to interface a wide range of input devices to your RTU. Inputs can be powered by the module’s own +12 VDC Field Output Power or from external AC or DC power sources.

Applying a high positive or AC input voltage results in a logical ‘1’ in the status register, no or low input voltage results in a logical ‘0’. Negative DC input voltages cannot be used with DI-10 modules.

The DI-10 features software configurable pre-conditioning of inputs such as debounce filters, channel inversion and sequence-of-event recording selectable on any channel(s).

The DI-10 can also perform frequency, pulse or quadrature counting for up to 7 input channels (or pairs of input channels for quadrature counters).

DI-10 modules can be swapped while RTU is running without causing RTU restart. Inputs are cleared in RTU memory while module is removed.

11.3.2 DI-10 Options and Ordering Info Unless explicitly noted, all hardware versions of DI-10 modules are described in this manual. Comparing with its predecessor (v3.2), the newer DI-10 version (v4.3) has some differences in the module features and specifications and also has a new optional GPS time synchronisation of the sequence of event recording.

The DI-10 modules without “-48” suffix in their Order Code have Digital Inputs compatible with 12 V and 24 V control systems. The modules with the “-48” suffix in the Order Code have elevated change-over thresholds of Digital Inputs designed for use in 48 V and higher control systems.

Any DI-10 v4.3 module can be a GPS Slave, having its events timing synchronised to an accurate timing signal generated by a DI-10-[48]GPS v4.3 module (GPS Master) that has an additional interface for connection to an external 3rd party GPS device. Any number of GPS Slaves and GPS Masters can be installed in the RTU. With more than one GPS Master installed in the system, each of them will generate time synchronisation signal for the GPS Slaves in parallel, providing system redundancy if it is required.

11.3.3 Theory of operation Block-diagram of DI-10 v3.2 module is shown on the figure below.

DI-10 v3.2 Block Diagram




Digital Inputs are connected to the input optocouplers via series diodes, resistors and 3.6 mA current limiters. Optocouplers with integrated Schmitt triggers are installed on first four (high-speed) channels. When input voltage and, consequently, input current of an optocoupler exceeds its threshold, microcontroller (MCU) reads this input as ‘1’, otherwise it is ‘0’.

Block-diagram of DI-10 v4.3 module is shown on the picture below.

DI-10 v4.3 Block Diagram

Digital Inputs are connected to a digital serialiser via series diodes and over-voltage protection circuits. The digital serialiser has its threshold input current set (and limited) to 2.51 mA. External signal sources should be able to supply 2.51 mA current to the DI-10 v4.3 module. When the input voltage exceeds its threshold, the microcontroller (MCU) reads this input as ‘1’, otherwise it is ‘0’.

11.3.4 Configurable Functions The first 4 channels of the DI-10 v3.2 and all channels of the DI-10 v4.3 are high speed and capable of counting up to 10kHz, while channels 5 to 16 of the DI-10 v3.2 can count up to 1 kHz.

Seven user-configurable counters are available which appear as 16-bit unsigned integer values in the analogue input register. Each of these counters can be configured either to measure frequency, to count pulses or to decode quadrature signals. Any channel from 1 to 16 can be assigned as an input to any frequency or pulse counter. Any pair of eight channel pairs (1-2, 3-4, etc.) can be assigned as inputs to any quadrature counter.

Channel inversion can be configured on any input channel. Normally a high voltage level results in a logical HIGH state (1) to be set in the digital input register with the corresponding LED illuminating on the front panel. By enabling channel inversion, a low voltage level applied to an input will result in a logical HIGH (1).

Software debounce can be activated on any input channel. The time constant can be configured from 1 ms to 250 ms. When AC inputs are used, the input channel must be configured with the debounce filter set to ‘AC Filter’ as shown below.




A 1 ms debouncing is automatically enforced when ‘AC Filter’ is chosen.

11.3.5 Sequence of Events Recording Sequence-of-Event (SoE) recording can be configured for any input channel. When enabled, any change of state (event) on the input is logged to 1 millisecond resolution.

These events are automatically included in the Event Log of the RTU. The DI-10 module has an internal timer that is synchronised with the Real Time Clock of the processor.

Timestamps of the DI-10 v4.3 are guaranteed to be within ±2 ms of UTC time when optional GPS synchronisation feature is used in the RTU system.

The DI-10 module has a buffer capable of storing 1000 events. This means bursts of up to one thousand events can be recorded at a time. Events are uploaded to the processor module at a maximum rate of 100 events per second.

Please note that SoE recording is not supported when using a PC-1 processor.

11.3.6 GPS T ime Synchronisation (Optional) When a GPS device is attached to the DI-10-GPS module, it will synchronise the time on the CP-30 processor and all other DI-10 modules (GPS Slaves) in the RTU via signalling on the backplane. SoE timestamps on all DI-10 v4.3 modules will then be synchronised to the GPS time within 2 ms.

This feature does NOT work with other Kingfisher Plus+ processor modules (such as CP-12, CP-11, CP-21 and PC-1) nor with DI-10 v3.2 modules.

The GPS time synchronisation feature requires at least one DI-10-GPS module (GPS Master) per RTU. More than one GPS Master can be used to provide redundancy.

One of the unused backplane connections (24V power rail) is used to carry the time synchronisation signal between DI-10 modules.

WARNING. Installing DI-10 v4.3 modules on 24V backplanes (that are used in some old Kingfisher installations) will damage DI-10 modules and void their warranty.

To support time synchronisation of the DI-10 modules across multiple backplanes, the time synchronisation signal must be connected between them. This signal is available on backplane power connector J14:

Backplane Power Header J14




Only two rails (24V and 0V) are required to be connected for time synchronisation between backplanes to work.

The following cables can be ordered from Semaphore to provide required connections:

• BPC-01 or BPC-02 Backplane Power Cables. WARNING. All power rails of the connected backplanes will be connected as well.

• BPC-02-GPS time synchronisation cable. • BPC-SPLIT splitter cable if more than two backplanes need to be connected.

The DI-10-GPS has an RJ-45 jack for direct connection of a Garmin GPS16x-HVS device. It is located directly underneath the LED display of the DI-10-GPS module.

The Garmin GPS16x-HVS can be ordered from Semaphore directly or via many commercial outlets.

RJ45 Jack for GPS device

RJ-45 pin-out and wire colours of the Garmin GPS16x-HVS are shown on the DI-10 v4.3 block-diagram. If a different model of GPS device is to be used, an adapter should be constructed using signal information in the table below.

12. DIGITAL OUTPUT MODULES

12.1 Overview The digital output modules provide relay and transistor outputs to the Kingfisher series of RTUs.

The DO-1 and DO-2 offer relay outputs, eight and sixteen respectively, while the DO-6 is transistor based.

The DO-6 is compatible with the TEL-REL-00x series of relay output boards to allow for higher current and voltage switching.

12.2 Switching Inductive Loads When switching inductive loads, users should be mindful of possible reduced relay service life due to back-EMF. To mitigate this negative effect, suppression circuits should be used when switching inductive loads.

14. COMBINATION IO MODULES Combinational IO modules provide digital and analogue IO in a single module. They can be installed in any 4, 6, or 12 slot backplane.

14.1 IO-2: Combinational Digital IO Module

14.1.1 Overview • 8 SPST relay outputs • Digital inputs

This module can be installed in any slot of a 4, 6 or 12 slot backplane.

Electrical Hazards









câblage.


Digital Inputs The digital inputs are designed to be powered using an external power supply. A wide range of digital input devices can be used such as push buttons, limit switches and electronic proximity switches. Current through an input (in either direction) results in a logic 1 in the status register. Power to operate the field devices must also be supplied by the user.




Digital Outputs The output points are arranged in one group of eight points with one common. The output switching capacity of each output is 2 amps. The relay outputs can control a wide range of load devices such as motor starters, solenoids and indicators. Power for the internal relay circuits is provided by the +12 VDC bus on the backplane. The user must supply the AC or DC power to operate the field devices. An internal fuse protects the relay contacts should ratings be exceeded.

Block-diagram of the IO-2 module is shown on the figure below.

This module can be installed in any slot of a 4, 6 or 12 slot backplane.

Electrical Hazards









câblage.


Analogue IO The IO-3 provides two signal ranges, 0 to 20 mA and 4 to 20 mA. The default range is 4 - 20 mA. A link on the rear of the module selects 4 - 20 mA (link installed) or 0 - 20 mA I/O for all channels.

Resolution of the converted signals is 12 bits binary (1 part in 4096). The sign bit is not used in the conversion process. All channels are updated four times per second (250 ms refresh time). The placement of the bits within the data word is shown below.

All inputs share a single common and all outputs share a separate common at the zero volt rail.


To minimise the capacitive loading and noise, all field connections to the module should be wired using a good grade of twisted, shielded instrumentation cable. The shields can be connected to E. The E connection provides access to the backplane (frame ground).

Digital IO Input characteristics are compatible with a wide range of user supplied input devices, such as push buttons, limit switches and electronic proximity switches, whilst outputs can control a wide range of user supplied load devices such as: motor starters, solenoids and indicators. Power for the internal relay circuits is provided by the +12 VDC bus on the backplane. The user must supply the AC or DC power to operate field devices. An internal fuse protects the relay contacts should ratings be exceeded.

* Analogue inputs can be modified from current inputs to voltage inputs by lifting one pin (or by the complete removal) of the 250 Ω channel resistor. Each channel has its own resistor, so any combination of channels can be converted. It is recommended that modules be returned to Semaphore for factory conversion if required. No responsibility will be taken by Semaphore for damage caused to boards during modification performed by clients. The circuit board resistors to change are: R39, R41, R43 and R45 (channels 1 to 4 correspondingly).

14.4 IO-5: Combinational Analogue / Digital IO Module

14.4.1 Overview • 4 analogue inputs • 1 analogue output with open line detection • 4 digital inputs • 4 sinking solid state outputs


Analogue IO Input protection for the module is sufficient to guarantee operation with reduced performance with up to 1500 V common-mode. The module provides electrical isolation of externally generated noise between field wiring and the backplane through the use of optical isolation.


Resolution of the converted signals is 12 bits binary (1 part in 4096). The sign bit is not used in the conversion process. The placement of the bits within the data word is shown below.

LSB MSB

0 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 0 0 0



For analogue outputs, an Open Line Detection circuit will indicate whether current loop is open or closed. Please note that open line detection circuit performance cannot be guaranteed when AO value is set to less than 1% (328 decimal) of full scale in the 0-20 mA range.




The IO-5 provides two signal ranges, 0 to 20 mA and 4 to 20 mA. The default range is 4 - 20 mA. A link on the rear of the module selects 4 - 20 mA (link installed) or 0 - 20 mA I/O for all channels.

Digital Inputs For high speed isolated digital inputs are provided on the module. All four digital inputs share on one common rail.

All channels can be configured as pulse counters that appear 16 bit unsigned integer values in the analogue input registers of the RTU processor module. Because of processor module limitations, only channels 1 and 2 can be configured as pulse counters when used with the CP-11/12/21 and PC-1 processors (Toolbox 32). All four channels can be used as pulse counters when used with CP-30 processor module (Toolbox PLUS+).

Input characteristics are compatible with a wide range of user supplied input devices, such as push buttons, limit switches, Hall sensors, proximity switches, etc.

Digital Outputs The IO-5 provides 4 open-drain (sinking) outputs for controlling various loads. Power for the loads can be provided from the on-board isolated +24 VDC power supply or from an external power source.

The IO-5 output channels provide continuous protection from overloads.

Installation Note: The holes in the MBR-3 brackets that are used to attach the brackets to the back of the backplane are drilled oversize to accommodate slight variances in racking equipment. By loosening these screws, pushing the brackets toward the centre of the backplane and then re-tightening the screws, the unit will fit freely into any correctly sized 19-inch rack.




16.2 TEL-RAK-002: 19” Rack Mounting for BA-4/6/40 A four slot backplane (BA-4 or BA-40) or a six slot backplane (BA-6) is mounted in a 19 inch rack using a TEL-RAK-002 mounting bracket. One BA-6 or two BA-4/BA-40 backplanes can be attached to the TEL-RAK-002 using the surface mount brackets supplied with each backplane. The TEL-RAK-002 is supplied with eight M3 x 5 mm screws for attaching the backplane(s).




16.3 Battery Bracket: 7 Ah Battery Mounting Bracket When using a 7 Ah backup battery, a standard battery holder is available for mounting on an enclosure gear plate. The bracket supports the battery and allows a General Power Outlet (GPO) to be mounted on the front using M3 x 10 mm pan head screws. The battery holder also allows an ISB50LN lightning arrester to be mounted underneath.

18. APPENDIX A: SYSTEM INSTALLATION Superseded items are not present in this hardware manual.

For information regarding any modules not present in this document please refer to the Superseded Products Manual available on Semaphore Helpdesk.

To avoid fire hazards and exposure to electrical shock and other safety hazards, all instructions listed below must be followed.

Enclosure Requirements All components of a Kingfisher RTU shall be installed inside of an enclosure providing safety and environmental protection as required. The enclosure shall be made from metal or other material with a flammability rating of V-0 or better in accordance with the requirements of the IEC 60950-1 standard for a fire enclosure. An enclosure not required to prevent a fire hazard if the RTU is installed above concrete or another non-combustible surface.

An RTU shall be mounted with all modules in a vertical position as illustrated below. The enclosure must provide sufficient clearances for conventional air cooling, with a minimum clearance of 100 mm between the RTU modules and the top and bottom of the enclosure:

RTU Installation Example

1. Vent must be installed if enclosure has a battery. Install a second vent in lower right corner if battery capacity exceeds 26 Ah or if environmental conditions require greater airflow.

2. Install Backplane low enough to allow for airflow through modules. 3. Radio or Modem.

Note: Radio or Modem can be mounted on rear of door by using DIN rail. Ensure that the radio is mounted on the top left corner of the door to allow radio to clear the RTU modules when the door is closed.

4. Gear plate. 5. PSU-x AC Power Supply Unit. 6. Slotted duct (20 × 60 mm). 7. IO wiring terminal. 8. Double GPO.

One outlet for the RTU and a spare for a laptop. When 7 Ah battery is used, DGPO is mounted on side of battery bracket (available from your supplier).

9. Lightning arrester. Install high enough to allow easy access for antenna lead connection. 10. Battery bracket. Can rest on front lip of enclosure. 11. Earthing stud. Ensure GPO, Backplane and lightning arrester are connected to this point

using appropriate earthing methods. 12. Leave at least 30 mm clearance to allow room for glands and cables. 13. Cable glands mounted through gland plate. 14. Enclosure must not contain openings in this area to avoid fire risk to external

environment.




Mains Power Connection Only appropriately qualified and trained personnel can install and service this equipment. Mains Power must be connected in accordance with local national wiring rules and regulations. Building installation shall provide appropriate short-circuit backup protection, with its breaking capacity of at least 1500 A.

Always remove input mains voltage (by disconnecting power cord from the mains power outlet or by switching off an external circuit breaker, depending on installation) before performing any operation on this product. Failure to do so may cause fire and may result in a serious personnel injury or even death.

Disconnect power cord from the Power Supply Module and wait for its LEDs on the front panel to go OFF before wiring, removing or servicing.

Earth / Ground Conductors Earth / Ground conductors should be connected in a tree fashion with branches routed to a central earth ground point. This ensures that no ground conductor carries current from any other branch. This method is shown in the following figure.

Recommended System Grounding

Earth / Ground conductors should be as short and as large in size as possible. Braided straps or ground cables (typically green insulation with a yellow tracer - AWG #12/5 mm2 or larger) can be used to minimise resistance. Conductors must always be large enough to carry the maximum short circuit current of the path being considered.

Safety Earth / Ground Although safety of the Power Supply Module and other modules with the potentially hazardous voltage levels have been assessed and found to be in compliance with the appropriate requirements, an additional level of protection from a potential electrical shock can be provided by connecting the RTU backplane to the safety earth / ground.

The Earth / Ground rail of the backplane PCB can be grounded by mounting screws to the metal back-plate of the backplane when properly installed. Additional grounding wire straps should be used in case reliable screw connections cannot be assured. Earth / Ground connections should be made from one of the PCB mounting tabs to a system earth / ground terminal (usually a threaded stud) using a minimum AWG#12 wire and ring terminals. Use of a nut and star washer for each wire on the ground connection lug is recommended to ensure adequate grounding. Ensure the paint coating is removed under the lug to make good electrical contact.




All backplanes grouped together in a RTU system must have a common ground connection. This is especially important for backplanes that are not mounted in the same enclosure.

The best way to provide proper ground connections is to ensure that the RTU backplane metal frame is directly connected to the mounting panel (or rear plate) by connecting a ground strap from one of the ground lugs on either side of the backplane to the mounting panel or cabinet in accordance with local safety requirements.

Functional Earth / Ground Yellow / Green wire in the mains power cord provides only functional (NOT Safety) Earth / Ground connection and cannot be relied upon for safety purposes.
