1. P&B MICROVISIONPLUS, Motor Variant (MOTOR).

P&B Engineering's Microvision+ Motor Protection Controller is a highly sophisticatedmicroprocessor based motor protection and control unit, specifically designed to be used aswith 3-phase motors of full load currents below 15 Amps as an integral part of any type or

manufacture of Motor Control Centres. Microvision+, due to its small size and innovativedesign, is able to fit in to the smallest of starter compartments. The CT (current transformer)module supplied is din rail mounted and rated at 1A, 2A, 5A or 15A covering a vast range ofmotor starters. All of the require features are included to allow flexible control, protection andmonitoring of motor starters either by direct hard wired inputs and / or via the rear serial port,(RS485 or Profibus connection) with 1ms time stamping of events.

The Microvision+ can be used to control Direct On Line, Star-Delta 2 & 3, Direct On LineReversing, Air Circuit Breaker, DOL with Heater, Two Speed and Variable Speed Drive motorstarters.

Microvision+ monitors the current, voltage and optional temperature input to provide acomprehensive motor protection package. This is combined with all the necessary control andmonitoring functions and a high-speed communication facility. The unit is a small, easilyinstalled package supplied at a very competitive cost which makes this device the mostattractive Motor Protection and Control device available today.

All hard-wired control inputs are connected to the device via optically isolated inputs to enableall starting, stopping and tripping commands to be carried out by the unit. The status of allindividual hard-wired contacts is also provided both locally via the two line liquid crystal displayand remotely via any of the communication ports.

All Setting parameters are programmed independently for each unit via the integral keypad andliquid crystal display on the front plate or via any of the communication ports and PC basedsoftware package available for the Vision II series of products.

Microvision+ can be configured to support any motor starter application, protective functionscan be individually configured to enable or disable the tripping and alarm functions.

Tri-Colour Light Emitting Diodes mounted on the front plate give visual indication of the motorstatus i.e. ON / INHIBIT / OFF and ALARM / FAULTY / HEALTHY conditions.

Flexible high speed control via PLC or DCS systems is obtained through the MV2scommunication ports, allowing computer access to full control and monitoring of motor data,including: running data, motor statistical data and control input status.

4. Analogue Inputs.

4.1. Power Supply Live.

The Microvision+requires an AC or DC Voltage to supply the unit. A separate AC/DC voltage isrequired to supply the digital inputs (Control Supply), this can be taken from the Auxiliary

Supply, or a completely isolated supply can be employed.

The Microvision+can also be fitted with a Low Voltage Power Supply (PSU) and / or LowVoltage digital inputs.

The Microvision+ monitors the power supply assumed to be derived from the primary side of thecontactor within the starter cubicle or from the MCC busbars to provide an Undervoltage Restartfacility. When enabled in the Starter Settings page the Microvision+monitors the supply and inthe event of a failure will maintain the start signal to the motor for up to 200m seconds. Beyond200m sec the unit will trip the motor and should the power supply be restored to 95% within theprogrammable Restart Time (2.0 to 200s) the unit will restart the motor after a programmable

time delay (1-120s). Should the voltage not be restored within the programmable Restart Timethe motor will not be automatically restarted.

There is also a digital input that can be used to enable or block the Undervoltage Restart. If theinput is closed then a restart can occur, if open, then the restart is blocked. If no digital input isset to Restart then a restart will always occur.

4.2. Voltage Reference.

The Microvision+ monitors single phase voltage, which can be directly connected for voltages

up to 500V. In order that the Microvision+ can measure and display the actual voltage, thephase to phase or phase to neutral input must be selected in the settings. A reverse feature hasbeen included to allow incorrect phase connections to be rectified without the need to rewire.With the use of Voltage Transformer the Microvision+ can monitor voltages up to 22kV.

4.3. Current Sensor Inputs.

The current inputs to the Microvision+ are housed in a separate module designed to helpachieve the small size and form part of the integral starter cubicle. Available as eitherConventional Current Transformers or Hall Effect Sensors.

4.3.1. Hall Effect Sensors.

To allow MCC manufacturers to use the smallest size compartments P&B have developed anaccurate Hall Effect Current Sensor.

The unit is a compact 3 phase enclosed device. The Current Sensor comes complete with aribbon cable and connectors to plug directly into the associated dedicated terminal block. SeeAppendix 4.

The current sensor is available in 3 versions depending upon the calibrated rating for motor fullload ratings of 10-25, 25-50 & 50-150 Amperes. To give maximum accuracy the sensors are

normally calibrated to the actual drive current or cubicle rating prior to despatch.

Earth fault protection can be achieved via a special internal residual earth fault or as standard,a separate 1A CT input is provided for Core Balance CT connection.


11/66



4.3.2. Conventional Current Transformers.

Normally, the Microvision+ has provision to allow connection of standard 1 amp or 5 ampsecondary current transformers. The Earth fault measurement can either be a residualconnection from the three phase CTs, a special internal residual earth fault or via a CBCT.

Small Motor Starters can also be directly connected to Microvision+ to avoid the need of costlysmall ratio CTs.A standard 1A unit can connect from 0.5-2A FLC and a 5A unit can connect from 2.5-10A FLC.A 2A version allows direct connection of drives from 1A to 4Amps and a special 15A versionhas been developed to allow connections from 7.5A to 20A.

As with both the conventional CT connection or with the HES connection the special internalresidual earth fault can be used to offer reliable earth protection to directly connected drives.

4.4. Temperature Input.

As an option, the Microvision+ can be fitted with a single channel input to acceptthermistors ofeither positive or negative temperature coefficients by selecting either PTC or NTC in thedefault menu. The alarm and tripping range can be adjusted between 1000 Ohms and 30,000Ohms.

Resistance Temperature Detectors (RTDs) can also be connected to this input, if RTD is

selected. The alarm and tripping range can be adjusted between 0and 250C.

5. Microvision+ Control Outputs.

5.1. Output Relays.

The Microvision+ has 3 output relays which can be assigned as follows depending on the typeof starter that the motor is connected to.

OUTPUT RELAYSTARTER TYPE

RELAY 1 RELAY 2 RELAY 3

DOL RUN Programmable Programmable

S/D 2 STAR DELTA Programmable

S/D 3 STAR DELTA LINE

DOLR FORWARD REVERSE Programmable

2 Speed LOW HIGH Programmable

Where stated the corresponding output relays can be programmed with the following options:-

1. Not Used 7. Trip Fail Safe 13. Panel Possible2. Follow Contactor A 8. Alarm 14. Remote Possible3. Follow Contactor B 9. Alarm Fail Safe 15. Healthy Fail Safe4. Follow Inverse Contactor A 10. Healthy

5. Follow Inverse Contactor B 11. Warning6. Trip 12. Serial Possible


12/66



5.2. Relay Settings.

Follow A.If an output relay is programmed as Follow A its state will mirror the state of output relay 1.When a relay is programmed as Follow A a delay may be assigned.

Follow B.If an output relay is programmed as Follow B its state will mirror the state of output relay 2.When a relay is programmed as Follow B a delay may be assigned.

Inverse A.If an output relay is assigned as Inv. A its state will always be the inverse of the state of outputrelay 1.

Inverse B.If an output relay is assigned as Inv. B its state will always be the inverse of the state of outputrelay 2.

Trip.If an output relay is assigned as Trip then this relay will change state from the de-energised tothe energised relay contact when triggered by any protection function or external deviceconnected to the relay that is configured to trip the motor.

Trip Fail Safe.If an output relay is assigned as Trip FS (Trip Failsafe) then this relay will change state fromenergised to the de-energised relay contact when triggered by any protection function orexternal device connected to the relay that is configured to trip the motor.


13/66



Alarm.If an output relay is assigned as Alarm then this relay will change state from de-energised tothe energised relay contact when triggered by any protection function or external deviceconnected to the relay that is configured to alarm.

Alarm Fail Safe.

If an output relay is assigned as Alarm FS then this relay will change state from energised tothe de-energised relay contact when triggered by any protection function or external deviceconnected to the relay that is configured to alarm.

Healthy.If an output relay is assigned as Healthy this relay will be in its de-energised state at all timeswhile the unit reports the motor as being healthy. This relay will be energised when the unitregisters either an Alarm or Fault condition or the motor has been inhibited from starting.

Warning.If an output relay is assigned as Warning then it will change state when any enabled protectionfunction has exceeded its pickup value.The relay is not latching. When the pickup setting is no longer violated the output relayassigned as Warning will be de-energised. The Warning relay does not wait until the expiry ofa trip or alarm timer before being energised. It will energise immediately after an enabledprotection feature has its pickup point violated or a digital input registers a fault status.

Serial Possible.If an output relay is assigned as Serial Possible this relay will be energised only when themotor is available to be started through the serial port, via a serial command. For details onconfiguring possible start sources see sections 9.3.4.1. and 15.

Panel PossibleIf an output relay is assigned as Panel Possible this relay will be energised only when themotor is available to be started from the front panel of the relay. For details on configuringpossible start sources see sections 9.3.4.1. and 15.

Remote Possible.If an output relay is assigned as Remote Possible this relay will be energised only when themotor is available to be started from a remote station via a digital input. For details onconfiguring possible start sources see sections 9.3.4.1. and 15.

Healthy Fail Safe.If an output relay is assigned as Healthy FS (Healthy Failsafe) this relay will be in its energisedstate at all times while the unit reports the motor as being healthy. This relay will be de-energised when the unit registers either an Alarm or Fault condition or the motor has beeninhibited from starting.


14/66



6. Microvision+ Control Inputs.

The Microvision+offers 5 digital inputs to provide full control and indication for the motor starter.The supply to these terminals is derived from a separate Control Supply to the relay. As thedigital inputs are completely isolated from the relays internal supply it is possible to have fieldinput signals at a different voltage or phase from the relays auxiliary power supply.

The 5 inputs are chosen by the user from the list described in the following sections.

6.1. Start A and Start B Inputs.

When one of these inputs are closed the corresponding output relay is energised as long as theStart Setup Sources has been set accordingly (see sections 9.3.4.1. and 15),and provided allother External Faults are in the healthy state. Start A only is used for DOL, DOL Forward, Staror Low Speedcontactors whilst Start B is used for DOL Reverse or High Speed. The startersettings menu allows these Start inputs to be either momentary, i.e. from push buttons or

maintained, i.e. from PLC outputs not both.

6.2. Stop Input.

If this input is open circuited the motor will be switched off and inhibited from starting as long asthe Stop Setup Sources have been set to allow the stop to be active from the remotesource.(see sections 9.3.4.1. and 15).

6.3. Emergency Stop.

This input allows the Microvision+ to monitor the status and provide indication of the state ofany of the external Emergency Stop buttons which are normally directly wired to the contactorclosing circuit. Opening of the input causes a trip with an option to alarm depending on theProtection Settings. Emergency Stop is only disabled when used for contactor applications,(short circuit protection is also disabled) when the phase fault current exceeds 8 x In.

6.4. Contactor A and B Status.

These status inputs from the contactors allow the Microvisionto determine the status of boththe A and B contactors, also known as Relays 1 and 2. Cont A is the feedback signal for a Start

A command and Cont B is the feedback signal for a Start B command.

Monitoring of these contacts also provides protection against 'Control Open' (when aMicrovision+ START command is not confirmed by these inputs, Cont A and/or Cont B) and'Welded Contact' (when Microvision+ STOP command is not confirmed by these inputs). Onlywhen the Contactor Fault protection is enabled do these active faults appear under warrantedsituations.


15/66



6.5. Test Mode.

When in the Test mode the Microvision+will disable Undercurrent Protection, Undervoltage,Single Phase and Phase Sequence protection functions, as well as the External Faults if set toDisable in Test.This allows full functional testing to be performed without the need for voltage or current

injection and will allow secondary injection testing to be carried out on all protective functionsexcept for those disabled by the feature.

6.6. Reset Fault.

This input enables the operator to reset a Microvision Plus Fault or Alarm condition. The Inputcan only perform a reset if the following conditions are met:

1. The Protection Settings for the specific fault or alarm are set to allow remote resets.2. The condition that caused the Fault or Alarm to occur no longer exists.

Providing conditions 1 and 2 are met an operator can override the settings in the ProtectionSettings by closing the Authorise digital input and pressing the Reset digital input.

6.7. Auto/Manual and Local/Remote Inputs.

These inputs are used to determine the source of both the Start Signal and Stop Signal to themotor. They are configured in the Start Setup Source and the Stop Setup Source. (Seesections 9.3.4.1. and 15)

6.8. Speed Switch.

Closing of this input reduces the trip time on the cold and hot curves by 50%. A tachometer isgenerally used on the rotor to determine if the shaft is turning the transducer is fed to this input.This provides a faster trip for stalled motors.

6.9. Authorise.

This function can be programmed as a digital input to allow a physical key switch to override thepassword and reset all faults. This input can be used to restrict fault and alarm reset, if the Autoand Panel reset options of protective functions are disabled a fault can only be reset from thepanel if the authorised input is closed. The use of the "Authorise" function will override thepassword. All data menus, display scroll and drive control are accessible without requiring theuse of the "Authorise" or "Password" functions if these are enabled.

Should a digital input be set to Authorise then the user will be unable to Disable the PasswordSetting on the relay. To Disable the password the Authorise input must be assigned as anotherdigital input or set to Not Used.

6.10. External Faults 1-5.

The flexibility of the External Fault inputs gives Microvision+ an intelligent PLC aspect toprotective relaying.External Faults are voltage based and are assigned to digital inputs to perform a wide variety ofroles. Multiple plant interlocking, process shutdown or for use as a gateway onto the serial

network for digital signals via the Microvision+.External Faults can be configured as independent protective functions and can be configured toany combination of; Trip, Alarm, Inhibit or just to Stop the drive. The normal reset types areavailable;Auto, Panel, Serialand Remote.The fault status of the input is programmable such that OFF = Faultor ON = Faultwhere theinput is fed from either a normally closed (NC) or normally open (NO) source.The trip time (or time to take the configured action) is settable in the range 1 to 60 seconds.

Each External Fault text string (EXTERNAL 1 etc) can be reconfigured to any character andnumerical string desired via any of the serial ports.

6.11. Restart.

This input will inhibit or permit an Undervoltage Restart to take place. This is to allow thedifferentiation between power losses that would and would not allow an automated restart ofthe drive. If the input is closed a restart can occur and if the input is open then the restart will beblocked.

If no digital input is set to Restart then an Undervoltage Restart would always occur, if enabled.

7. MV2 Serial Ports.

7.1. RS485

The Serial Port supplied with Microvision+ as standard utilises a half duplex RS485 protocolallowing up to 32 units to be daisy-chained together, or to be multi-drop connected with a singleshielded twisted pair cable.The Microvision+ in addition to its very comprehensive protection and control features has beenequipped with a very powerful data communications system. This extends its boundaries farbeyond a motor protection controller into the realms of a complete motor management system.It provides high-speed data acquisition to supervisory computers to form a complete motormanagement system.

Each Microvision+ can be connected to an isolated data highway using RS485communications. Up to 32 units can be connected to each data highway. The host system can

interrogate the unit to monitor motor status, running conditions, historical data and fault data aswell as control functions such as a start and stop to the motor and reset fault / alarm conditions.

The Microvision+ is available with P&B network gold (P&B protocol) installed for use with theXcell Data Concentrator for fully Integrated Protection, Control & Monitoring Systems with fulldual redundancy or with a Slave implementation of Modbus RTU protocol for small systems anddirect Modbus access to devices where data concentration is not required.

7.2. ProfibusThe Microvision+ can also be fitted with a standard 9-way d-type connector in place of theRS485 connection to provide a Profibus DP interface. See section 12.1.

7.3. RS232The unit is additionally fitted with a front mounted RS232 port to allow relay interface using theP&B Protocol regardless of the rear port configuration.

Full details of the protocols, device mapping, gds files and other support documents areavailable on request.

Information on the Xcell Data Concentrator is contained in the P&B Integrated Protection &Control System Integrators Manual, available on request.

8. Microvision+ Faceplate Functions.

The MV2Faceplate has been designed to allow Motor Control and to provide display andaccess to a data parameters, viewing and changing of setting parameters, trip and alarmmessages.This is achieved by using 2 tri-colour LEDs, a two line LCD display and 4 software driven

function keys that change function depending upon which page of the menu structure is beingviewed.

This eliminates the need for additional indication devices on the front of the motor starter panelsuch as Lamps, Ammeter, Voltmeter, Hours Run Indicator, Operations Counter, etc. whichhelps reduce the cost of the motor starter panel and gives improved reliability by the reductionof separate components.

The up and down buttons allow the display to scroll through the measured values and devicesstatus.

When updating firmware the unit can be forced in the program mode by holding down both theup and down arrow buttons as the unit is powered on. The unit can be updated using the rearRS485 port if fitted, or the front RS232 port.

8.1. LED Status.

The LED's operate as follows:

9.3.4.1. Start / Stop Source Settings.

In this screen the user can define fromwhere the motor can be started (Panel,Serial, Remote) depending on the positionsof the Local/Remote, Auto/Manual and Test

inputs.Each 1 represents a YES to permit startdrive control in that state, a 0 denotes aNO.

The Nxt button skips along to the next character and condition (L/A Pan), the UP and DOWNkeys change the logic state from 0 to 1 or vice versa.

In the example above, the drive can only be started whilst in;

LOCAL and AUTO from the relay front panel,

LOCAL and MANUAL from a serial command,REMOTE and AUTO from a Start A (or B) digital input,REMOTE and MANUAL from a Panel and Serial command

and when in TEST from a Start A (or B) digital input.

12. Serial Settings.

Serial Enabled / Disabled.This setting allows the user to enable the Microvision Plus serial communications port.This setting must be set to Enable if communication with the relay through any seriallink is required.

Drive Number.This setting range 1 to 32 (125 Profibus), with a default setting of 1, identifies theMicrovision Plus unit to the Xcell unit (or any Master device connected to the Datahighway) to which the RS485 or Profibus port is connected. When updating firmware theauto program mode requires the drive number to be 1.

RS485 Baud Rate.This setting allows the user to configure the appropriate communications baud rate suchthat the Microvision Plus can communicate effectively on the Data Highway to which it isconnected.

RS232 Baud Rate.

This setting allows the user to configure the baud rate for the front mounted RS232 port.

Serial Delay.The Microvision Plus may be configured to respond to a request for information from theserial port instantly or after a designated delay.

A communications delay may be beneficial to ensure the Master device on the Data

Highway receives all information sent back by the Microvision Plus without enduring datacollisions on the network.

Fast Scan Words.A Fast Scan is a system used when operating in conjunction with the XCell DataConcentrator. As the XCell polls relays attached on its network, the fastscan settingsallows the user to select important data to be read back faster.

The data on the communications link is broken into Fast Scan Data (or Process CriticalData) and Slow Scan or Full Read Data (Electrical Engineering Data).

The amount of Fast Scan Data to be sent back to the XCell in response to a request isconfigurable. This setting has the range 4, 6 or 8 Words. A setting of 4 Words will give 3Fast Scans. The remaining Word is taken up by the Thermal Capacity. A setting of 6Words will give 5 configurable Fast Scans and a setting of 8 Words will allow 7configurable Fast Scans.

The configuration of Fast Scan is not necessary unless the Microvision Plus in used inconjunction with the XCell unit.

Fast Scan 1 to 7.Each FastScan number can be programmed to export important data when requested.

This number references an internal address in Microvision Plus and allows configurabledata mapping between units. Typical data could be Average Phase Current, Motor Loadand so on. A table of the FastScan reference numbers can be found inAppendix 6.


33/66



Max Scan Time.This setting need only be used in order to limit the amount of data traffic on a RS485network. Dynamic data can change rapidly, this setting allows the Microvision Plus tolimit the number of updates it makes to its Fast Scan values.

Protocol.

The RS485 serial communications port may be configured to operate using a slaveimplementation of Modbus RTU or P&B Engineerings own protocol P&B Standarddesigned to remove some of the speed issues associated with a function based protocollike Modbus.

Parity.This setting allows the user to set the parity to match that of the host system on theserial link. The options are Odd, Even and None. Not required if Profibus.

Serial Timeout Protection.

This setting is a protective function and is described in detail in section 16.1.1.

Serial Inhibit.

This setting is a protective function and is described in detail in section 16.1.2.

Profibus DP Fault.

This setting is a protective function and is described in detail in sections 12.1 and16.1.21.

12.1. PROFIBUS DP (Optional)

PROFIBUS-Interface Pinout

The PROFIBUS can be accessed via a 9-pin connector located at the rear of theMIcroVision Plus, this replaces the 3 wire RS485 connection. If the RTD option is alsoused it may be necessary to use a port saver in addition to the Profibus connector toallow sufficient clearance for the plug and cable arrangements.

The interface has separated potentials and a pin-layout as specified in the DIN 19245.

When using the Microvision Plus with the dedicated PROFIBUS option, the followingprotocols can be used, P&B Std., MODBUS RTU, P&B Inv. and P&B DP.When using all but the P&B DP option, the protocol should be implemented inaccordance with the protocol specifications.However, if the P&B DP option is chosen then the communication is handled in thefollowing way.

Data is automatically configured and transmitted by the Microvision Plus to thePROFIBUS master without the need for the PROFIBUS master to send requests to theMicrovision Plus, as is the case when using any of the other protocol options. Theamount of data returned by the Microvision Plus is determined by the number offastscan words chosen. Only one byte is used for the command outputs to theMicrovision Plus.

When using the P&B DP protocol option then one of the following should be chosenfrom the GSD file module list: -

8 Bytes In + 1 Byte Out (choose this option if fastscan words is set to 4)12 Bytes In + 1 Byte Out (choose this option if fastscan words is set to 6)16 Bytes In + 1 Byte Out (choose this option if fastscan words is set to 8)

P&B DP Input Structure

First Byte = MVP Logic StatusSecond Byte = MVP Thermal CapacityThird & Fourth Bytes = MVP FS1Fifth & Sixth Bytes = MVP FS2Seventh & Eighth Bytes = MVP FS3

If 6 fast scan words chosen then the additional bytes are included.

Ninth & Tenth Bytes = MVP FS4Eleventh & Twelfth Bytes = MVP FS5

If 8 fast scan words chosen then the additional bytes are included.

Thirteenth & Fourteenth Bytes = MVP FS6Fifteenth & Sixteenth Bytes = MVP FS7

13. Motor Settings.

CT Primary.This setting allows the user to program the primary current rating of the protection classcurrent transformers on the supply phases. It is assumed that all phase currenttransformers are of the same rating. There is no need to enter the current transformer

secondary rating as the MVP is pre-programmed depending on whether the relay hasbeen purchased with a 1A, 2A or 5A CT input.

If the Hall Effect Sensor (HES) is used then the CT Primary should be set to thecalibrated setting of the Sensor.

If motors are connected using the direct connect technique then the CT Primary shouldbe set as per the rating of the CT Secondary.

On selection of the two-speed starter types the CT Primary setting will offer twosettings, CT Primary (LOW) and CT Primary (HIGH). This allows connection of twoindependent sets of current transformers to the MVP to monitor current in the fast andslow supply arms to the motor.

If only one set of current transformers is used then these two values are set to the sameCT Primary value. It must be noted that although the Primary values can differ theSecondary values must be the same i.e. 1A, 2A or 5A.

The HES cannot be used in this type of dual-set CT application.

VT Primary.

This setting allows the user to program the primary voltage rating of the voltagetransformer (if used).

VT Secondary.This setting allows the user to program the secondary voltage rating of the voltagetransformer (if used).The VT Primary and Secondary should be set to the same value if directly connectingthe voltage input without a step-down transformer.

Full Load Current (FLC).The FLC is the motors continuous maximum Full Load Current rating as provided in the

motor manufacturers data. The settable range is dependant on the CT Primary setting.

The FLC setting enables all protective functions except Undercurrent and LoadIncrease to be set in terms of a percentage of FLC and enables the MVP to display theMotor Load in terms of a percentage a FLC.

Running Current (RC).This setting allows the user to program the motors Running Current when supplying atypical load at normal speed.

This value is typically less than the motor FLC rating and enables the protective

functions (Under Current and Load Increased) to be set in terms of a percentage of thisvalue.

Voltage.This should be set to the line voltage of the supply. It is necessary for power calculationsand is used for the Under / Overvoltage, Undervoltage Restart and UndervoltageLockout protection features.

As an example if the voltage input was connected between two phases on a 415V

system this setting would be 415V. If however the voltage input was connected betweena phase and neutral then this setting should be 240V.

Voltage Ref.This parameter can be set to Ph-N (Phase to Neutral) or Ph-Ph (Phase to Phase) with areverse feature to avoid re-wiring for phase correction to match the connection typeabove.

E/F Primary.This setting allows the user to program the primary current rating of the protection classcurrent transformer used to measure the earth fault current.

If a residual current transformer connection is used to detect earth fault then the samesetting as for CT Primary should be used.

If the Internal Residual Connection is used for earth fault protection then this setting ishidden.

KW Sample Period.This setting range 5 to 60 min in steps of 1min determines the period over which ameasurement is taken to integrate the Kilowatt Hours value.

14. Starting Methods.

The MVP relay is designed to be used as an intelligent motor starter for LV systemsoffering comprehensive protection and control features.A number of starting methods are catered for;

14.1. Direct On Line (DOL)

Direct On Line starting is used for electrically held contactors and allows the motor to berun in one direction only. It applies the full line voltage to the windings immediately uponstarting.

DOL Starter expects Start A to be used a hardwired digital input control (momentary ormaintained).Output Relay 1 (RUN) will close to pull in the contactor, Cont A digital input should beused if contactor feedback is required through the digital inputs or contactor fault

protection is needed.Output 1 will release when stopped or tripped.Typically the inrush current of a 415V motor would be 6x FLC, hence the thermal modelprotection, t6x. Higher voltage systems generally have lower inrush demands.

14.2. Star / Delta 2 (S/D2)

This starting technique is typically used to reduce the starting currents normally seenwhen starting a motor by Direct On Line.By reducing the voltage applied to the motor windings the current is also reduced, as is

the starting torque. Care must be taken to ensure the motor can generate enough torqueto accelerate on start-up when connected in STAR.

Start A is used as the hardwired or remote start signal and closes Output Relay 1. Thisoutput is used to pull in a contactor which connects the motor in a star type connection.Cont A is used for feedback and / or contactor fault protection.The Star connection provides root 3 of the system voltage to the motor. This has theeffect of limiting the inrush current to 2x (as opposed to 6x for normal 415V drives).Once this current increases and falls below 100% of FLC. Output relay 1 opens.If the current fails to fall below 100% FLC then Output relay 1 opens after the Max timein star setting.

After the transition time Output Relay 2 closes to pull in a contactor connecting the motorin a delta formation. Cont B is used for feedback and / or contactor fault protection of thedelta contactor.Once the delta inrush current falls below FLC the MVP will consider the motor asrunning.Maximum Start Time protection functions from the time at which the unit transfers to thedelta starter.

Output Relay 1 can be held closed for the duration of the Max Time in Star by settingStay in Star to YES irrespective of the normal current based change-over.


39/66



14.3. Star/Delta 3 (S/D3)

For Star / Delta 3 the operation is the same as for the S/D2 type with the exception thatOutput Relay 3 controls the LINE contactor.Once a Start A command is received both the Star and Line contacts closes, upontransition the Star opens as normal. The line contact remains closed throughout and

only released when the drive is stopped or tripped.

For both S/D2 and S/D3 the Start Time (statistical data) is determined solely by the timetaken from the motor starting in Star formation to the transition to the DELTA connection.

14.4. Direct On Line Reversing (DOLR)

With Direct On Line Reversing Output Relay 1(FORWARD) is used to control the motorin the forward direction and Output Relay 2 (REVERSE) is used to control the motor inthe reverse direction. The full line voltage is applied to the motor windings immediately

upon starting in either direction.Start A and Cont A are the start command and feedback for the forward direction. StartB and Cont B are associated with the reverse direction.

14.5. 2-Speed / DOW 2-Speed

In 2-Speed mode Start A controls Output Relay 1(LOW) and is used to control the motorin the Low speed with Cont A used as feedback confirmation and / or protection.Start B controls Output Relay 2(HIGH) and is used to control the motor in the high speedwith Cont B used as feedback confirmation and / or protection.

This type of starter is used on 2-Speed motors which typically have 2 sets of windings.Different sets of CTs can be used if the windings are considerably different for oneanother.

Example. The high speed winding is rated at 90 Amps, therefore 100/1A 5p10 2.5VACTs are used. If the low speed winding is rated at anythi
