3.3 Climate Control

An integrated climate management system controls the temperature within the cabinet, providing optimal operating conditions for the equipment and battery. Different cooling/heating units (e.g. air conditioners, heat exchangers, fans and air filters, heaters) are available. Delta OutD V cabinets can also be equipped with an advanced, hybrid cooling system with Air Ventilation or Active Cooling (Air Conditioner).

The power system controller (PSC 3) can be used as a climate controller to provide optimal climatic conditions for the equipment by eliminating problems caused by high or low temperatures, which are normally present in the outdoor environment.


3.3.1 Air Ventilation

Air Ventilation (AV) is the simplest cooling system. It is often used as a basic cooling system for outdoor application in a non-critical temperature climate environment. It is also installed in advanced, hybrid systems together with Air Conditioners.

With AV systems the cabinet is equipped with a set of Delta fans installed in the roof space. They ensure appropriate airflow for cooling the equipment inside. The fresh air is sucked in through the inlet holes in the front door and the air then passes through an air filter installed in the internal door surface and passes into the cabinet interior. Finally, after heating up by internal equipment the air is pushed out via holes between the cabinet body and the roof.

Fans

Front door

Figure 4. Air Ventilation cooling system

With the simplified application the fans are controlled by a thermal switch TF (ON/OFF mode) located on the internal right supporter (only systems with 2 or 4 Delta EFB1248 fans). When the fans start their operation the temperature is set by positioning the thermo switch knob. The logic of this temperature control is presented in Figure 5.

Figure 5. Fan and heater control by thermal switches

In a more advanced system, fan control is embedded into power system controller PSC 3. There are two methods for how the fans are controlled:

• Simple ON/OFF mode – Useful only for systems with 2 or 4 Delta EFB1248 fans. When the fans start the temperature is set by the PSC 3 parameter TF (25 °C). The logic of this temperature control is the same as presented in Figure 5. The only difference is that hysteresis is set (as a parameter) at a different (smaller) level.

• Speed control mode – The fans’ operation is controlled by PSC 3 via a CTRL-PWM board using pulse width modulation. This method only applies to a system with 2 Delta EFB 1748 fans. The speed of both fans is controlled simultaneously: the control is based on the temperature measured by a Tint temperature sensor (PSC 3 controller) located inside the cabinet in the user space. Three setting points T1,T2, T3 (standard settings 20 °C, 25 °C, 30 °C ) are used to set the speed from 0 % to 40 %, 65 % and 100 % of the maximum fan rotation speed. The logic of this temperature control is presented in Figure 6.

3.3.2 Air Conditioner

Systems with Air Conditioners AC (active cooling) are very useful for hot environments. In such conditions, it is the only solution that offers the possibility to have a lower temperature inside than outside.

Air Conditioners are mounted on the front doors of the cabinets. In the standard application they are controlled by internal thermostats or integrated (own) controllers. The standard (factory) setting of such a device is usually 35 °C (return air) when the AC starts cooling.

For more details, see the specific user manual for the Air Conditioner (included with the system).

3.3.3 Heater

OutD V cabinets are equipped with a 230V / 500W heater to protect the equipment installed inside against low temperatures. The heater is installed on the right internal side of the cabinet (see Figure 2). It is switched ON/OFF depending upon the temperature inside the cabinet.

There are two methods for how the heater is controlled:

• Control by thermo switch TH (ON/OFF mode) located on the internal right supporter. When the heater starts its operation the temperature is set by positioning the thermo switch knob. The logic of this temperature control is presented in Figure 5. Control by a PSC 3 controller (ON/OFF mode) via an additional relay. When the heater starts the temperature is set by a PSC 3 parameter TH (0 °C). The logic of this temperature control is similar to that presented in Figure 4. The


only difference is that the hysteresis is set (as parameter) at a different (smaller) level. The logic of this temperature control is presented in Figure 9.

3.3.4 Hybrid cooling system

Delta OutD V cabinets are also equipped with an advanced hybrid cooling system with Air Ventilation or Active Cooling (Air Conditioner). With this combination fan cooling is the main cooling unit for low and middle temperature conditions.The Air Ventilation is only suppressed by the Air Conditioner (AC) for high ambient temperatures (a few percent of the operating annual time).

Hybrid cooling systems with AV and AC provide a significant reduction in energy consumption compared to standard cooling with only AC units. Additional advantages include the reduction of maintenance of the AC and an increase in the operational life of the AC.

Air Conditioner

Figure 8. Hybrid cooling system

In hybrid systems all climate devices (fans, heater, air conditioner) are controlled by a PSC controller. The fans are switched ON and increase of rotation (speed control) depends on the temperature inside the cabinet measured by the Tint sensor (parameters T1, T2, T3 - standard settings 20 °C, 25 °C, 30 °C). When the temperature inside increases above the limit T4 (standard setting 35 °C), the Air Conditioner starts its operation and cooling. The operation of fans in hybrid systems is additionally related to the outside temperature measured by a Text PSC 3 sensor. This is located in the door in front of the air filter. Fans are stopped if the Text is higher than T4 - 2 °C (33 °C). There is no reason to pull warm outside air (> 35 °C) into the cabinet when the temperature inside is stabilized at the T4 level (around 35 °C) by the Air Conditioner. It is possible that the Air Conditioner works together with the Air Ventilation until the external temperature is higher than the temperature stabilized by the Air Conditioner T4 (35 °C) inside.


The operation and control logic of the hybrid climate system is presented in Figure 7.

3.3.5 Fan alarm

Fan alarm functionality is available (only for Delta Fans EFB 1748) in OutD V cabinets. An alarm (stoppage) is activated on the basis of 0/1 signals (R00) supported by the fan alarm output. This signal is transferred to the PSC 3 controller (via digital alarm input) and it is signalled by controller alarm LEDs and presented on the display according to the configuration. Fan alarm can also be monitored by controller alarm relays OUT1 ... OUT5 (dry contacts: C, NO, NC) according to the configuration.


3.3.6 Climate control setting

Warning! The climate setting applied in the outdoor system ensures the proper operation of the DC system components and the user equipment installed into the cabinet. If any adjustment to specific customer requirements is needed please contact authorised service personnel to make the modification in the proper and safest way.

4 Installation and commissioning

4.1 Installation

4.1.1 System cabinet installation

Step 1 Check if the foundation is well prepared for the installation (horizontal, level, dimensioning of the mounting holes or screws) (see the plinth dimension presented in the appendix).

Step 2 If the cabinet has to be lifted into place by a crane, follow the next steps. If not, go to Step 8.

Step 3 Remove the cabinet roof. In order to unscrew the two bolts located on the top front of the cabinet ceiling, pull the roof to the front to release the back fixing and remove the roof from the cabinet.

Step 4 Connect hang lines (length: minimum 1000 mm) to the four lifting eyes installed in the roof and lift the cabinet into position by crane.

Figure 10. Lifting the cabinet by crane

Product description, Delta OutD V outdoor cabinet Installation and commissioning 17

Step 5 Set the system cabinet down, standing it in place and straighten it, if needed, using aluminium or stainless steel pads.

Step 6 Bolt the cabinet to the ground using four bolts (M10/50mm). It is necessary to remove the plinth side covers to get access to the plinth mounting holes if there is no access from the bottom of the plinth base.

Step 7 This step is applied for OutD700 V cabinet only – omit this step when installing OutD1200 V or OutD1800 V. Use delivered wall mounting with/without pole mounting kits to install the cabinet on wall or pole locations. See Figure 11 for details.

Wall mounting kitCabinet plinth

Figure 11. OutD 700 V mounting option kits

Step 8 Install the cabinet roof into position (if it was previously removed).

4.1.2 Cabling

Warning! All circuit breakers must be in the OFF position.

Note! The input/output cables can be inserted into the cabinet from the bottom through the input sleeve packing in the cabinet plinth. In any case, sufficient cable length has to be ensured to make the connections inside the cabinet.


4.1.2.1 Grounding

Step 1 Connect the protective-grounding screw located on the rear side of the cabinet plinth to the main grounding bus bar of the site using the proper cable (16 mm²).

Note! In some DC systems installed in the cabinet, the common positive bar (L+) is not connected to the protecting bar (PE). Check the actual configuration of your DC system. If such a connection is required according local regulations, the internal cable (minimum 16 mm²) should be installed by a service professional to connect the positive bar (L+) to the protective-grounding bar PE on the right side of the cabinet.

4.1.2.2 AC main connection

The AC input terminals are located on the AC distribution panel (see Figure 3).

The system in its standard version is prepared to be supplied via three phases (L1, L2, L3, N, PE) or by single phase (L, N, PE) in TN-S configuration (3 x 230 / 400 Vac or 1 x 230 Vac).

There are a few variations of the AC distribution according to the AC line configuration and system requirement for AC load. The AC line supplying the cabinet and fuses in the external AC distribution has to be chosen according to the actual variant of AC distribution installed in the cabinet (See Table 2).

Step 1 Connect the AC line cables to the input terminals in the AC distribution – PE cable to the PE terminal, phase and neutral cables to the input main switch AC1.

Note! Use the wiring diagram supplied with the installation documentation to ensure the AC power supply has been correctly connected.

4.1.2.3 Battery connection

Step 1 Install the batteries in their shelves. Connect the internal battery cables so that the total nominal voltage of the each battery string is 48 V.

Step 2 Connect the system’s pre-installed battery connection cable marked as “+” to the free plus-pole of the battery string and the cable marked as “-” to the free negative pole. The battery strings are numbered according to the battery fuse they are connected to.

Step 3 Place the battery temperature sensor between the batteries in the battery area. Fasten the sensor cable to the cabinet cable supports.


4.1.2.4 DC-load connections

Step 1 Connect the distribution cables to the DC power supply system. Plus cables are connected to the positive bus bar (L+) of the system and the negative cables are connected directly to the terminals of the DC distribution circuit breakers 1F1 ... 1Fn.

Note! The maximum cable size for the connectors on the positive bus bar is 16 mm2. For the MCBs 1 ... 32 A it is 16 mm2, for MCBs 40 ... 120 A it is 35 mm2.

4.1.2.5 Alarm connections

Step 1 Connect the remote alarm cables to the alarm terminals: screw terminals or Krone connector. The alarms are usually connected so that the alarm circuit is closed and where there is a fault the circuit opens. See the Table 3 for information about the alarm cross connection configuration.

Note! Remote alarms are configured using the PSC 3 I/O assignments in the PSC3 Configuration and Supervision Tool menu.

4.2 Commissioning

4.2.1 Starting up the DC system (if configured)

Step 1 Install the rectifiers to the rectifier shelf. Lift the rectifiers into the cabinet onto their shelves, starting from the far-left slot and continuing to the right, but do not connect any cables or connectors at this stage. Fasten the rectifiers using the latches or screws (this depends on the rectifier type).

Bringing the system into use is presented below step by step.

Warning! Protective shields and other safety devices provided with the equipment must be in place when the equipment is operational.

During installation and maintenance, protective shields may be temporarily removed. Suitable insulated tools and appropriate protective clothing must be used. Fuses should only be handled using the tools provided for this purpose - for example, load-break switch handles.

Step 2 Switch on the main power supply to the system.


Step 3 Check that all the rectifiers LEDs indicate “OK”.

Note! Save the PSC 3 settings by making a backup of the setup files.

4.2.2 Controller calibration (systems with PSC 3 controller)

The system controller is pre-calibrated (including rectifiers) by Delta Energy Systems. Calibration is not needed unless changes have been made to the controller hardware or the controller display is different from the measurements made with calibrated test equipment during maintenance.

Controller calibration should be performed if the actual measured value differs more than ± 0.1 Volts from the value indicated by the controller.

If the measured actual value is within ± 0.1 Volts of the value indicated by the controller, go to Step 10.

Calibrate the controller system voltage according to the following instructions.

Step 1 Measure the system voltage between the positive bus bar [1, 3] and negative terminal on the DC output circuit breaker.

Step 2 Check the value “Usys” from the display.

Note! The default factory setting for output voltage is always 53.5 V.

Step 3 Log in to the PSC3 Configuration and Supervision Tool.

Step 4 Go to Configuration → Signal Processing Engine → Measurements.

Step 5 To open the “Usys” analogue measurement dialogue, click “Edit”.

Step 6 In the new Analogue Measurement dialogue, click “Calibrate”.

Step 7 In the Calibration dialogue, enter the actual measured value and click “Calibrate”.

Step 8 To permanently save changes made to the PSC 3 parameters, go to Configuration → Setup Update.

Step 9 In the “User Setup” section of the Setup Update dialogue, click “Save”.

Step 10 Log out of the PSC3 Configuration and Supervision Tool.

Step 11 Check the battery polarity by measuring the voltage over the battery circuit breaker.

Step 12 The voltage should be at most a few volts. If the voltage increases, the battery polarity is not correct and must be changed by switching the “+” and “-” cables connected to the batteries.


Step 13 Switch on the battery circuit breaker(s).

Step 14 Switch on the DC distribution circuit breakers connected to the load.

4.2.3 Testing the rectifiers (systems with PSC 3 controller)

The following must be done with a suitable DC load.

This is to test that the rectifiers can deliver power. The method is to first discharge the batteries for a while and then recharge them. The controller carries out the procedure which decreases the rectifier voltages below the discharging voltage of the batteries. As a result, in the case of battery failure, the system will not fail.


Step 2 Go to Battery → Control → Battery Test and click “Start”.

Step 3 The discharge process takes approximately 15 minutes.

Step 4 To stop the battery test from the controller, click “Stop” and exit the controller Web user interface. The rectifiers will recharge the battery.

4.2.4 Testing the control and alarm system (systems with PSC 3 controller)

Warning! Voltage values must be set according to the battery manufacturer’s specifications. Incorrect voltage settings may lead to possible damage to the batteries or danger of explosion.

Caution! Ensure that the equipment settings conform to the specifications for the system configuration. Incorrect settings may lead to system malfunction or damage.

Caution! Alarm limit values (trigger thresholds) must be set correctly. Incorrect settings may trigger false alarms and cause rectifier/inverter modules to switch off.

4.2.4.1 Confirming the configuration

The values are all pre-set at the factory and should not be changed without a proper reason.

Check the configuration either from the PSC3 Configuration and Supervision Tool or from the UIM/UIL display. The Web user interface is protected against unauthorised access by a username and password.



Step 2 Confirm the following settings:

Settings Web user interface UIM/UIL

Alarm limits Configuration > Signal Processing Engine > Event Definitions

6.1 THRESHOLDS

System voltage Battery > Control > Float Charge 7.1 FLOAT CHARGE

Temperature Compensation

Battery > Control > Float Charge 7.1 FLOAT CHARGE

Battery Test Battery > Control > Battery Test 7.5 BATTERY TEST

Equalise Battery > Control > Equalise 7.2 EQUALISE

Table 4. Confirming the configuration

Note! To permanently save changes to the PSC 3 settings, go to Configuration → Setup Update. Otherwise the changes will be lost after rebooting the PSC 3.

4.2.4.2 Testing the alarms

The operation of the alarm relays and LEDs can be checked in the PSC3 Configuration and Supervision Tool.

Step 1 Go to Maintenance → Alarm.

The Alarm Maintenance dialogue allows manipulation of alarms for maintenance and testing purposes.

An alarm set in the “Frozen”, “Set” or “Reset” state does not react to the source event as defined in the event conditions, but stays in the current position in case of “Frozen”, or changes to “Active” in case of “Set”, or changes to “OK” in case of “Reset”.

4.2.4.3 Checking the fuse monitoring

Step 1 Switch ON all the battery circuit breakers and the DC distribution MCBs which have loads connected.

Step 2 Switch the first load and battery circuit breaker to OFF.

Step 3 Ensure the alarms are indicated as configured.

Step 4 Switch the circuit breaker to ON.

Repeat Step 1 to Step 4 for all load and battery circuit breakers.

Note! When testing the battery fuse alarm, it may take a few minutes until the battery voltage decreases sufficiently (>300 mV). The active alarm can be read from the UIM/UIL display: go to “3.1 ALARM”.


4.2.4.4 Testing the rectifier and mains failure alarms

Test the rectifier failure alarm by removing the rectifiers one by one from the system and check the following:

Check the battery current from the display:

Step 1 Removing 1 rectifier + battery current (Ibatt) positive -> Non-Urgent Alarm

Step 2 Removing 2 rectifiers or more (not all) + battery current (Ibatt) negative (battery is discharging) -> Urgent Alarm

Step 3 Removing all rectifiers: load current (Iload) equals battery current (Ibatt) -> Mains Failure

The active alarm can be read from the display menu “3.1 ALARM”.

Note! During the test Usys Low and Usys High alarms may occur, which should be omitted at this stage. If there is no load connected to the system, no module alarm will occur. The additional module alarm (RF) does not light up any LEDs on the controller. The alarm can be seen in the menu display, and it is also seen in a remote location. It can be measured in the alarm cable (see alarm connections).

Step 4 Reconnect all rectifiers.

Note! If there are no load and batteries connected to the system, no mains failure alarm will occur.

Note! After testing, put all system covers back in their correct places.

4.2.5 Checking the Air Ventilation system

Testing the fans controlled by the thermal switch TF is described in the following procedure:

Step 1 Turn to the right the knob of the TF thermal switch to 60 °C – after that the fans should start.

Step 2 After the test, set the TF thermal switch back to the standard setting (25 °C).

Testing the fans controlled by the PSC 3 controller is described in the following procedure:

Step 3 Heat up the PSC 3 temperature sensor Tint by external heater to start the fans when the temperature is above the limit TF (25 °C) for fans controlled in ON/OFF mode or above the limit T1 (20 °C) for fans with speed control.


Step 4 Continue heating up the sensor Tint and observe the increase in the fans’ rotation up to the limit T3 (30 °C) for fans with speed control.

Step 5 In the hybrid cooling system (AV + AC), heat up the Text sensor to check if the fans stop when the external temperature is higher than T4 (35 °C).

Step 6 To test turning OFF the fans, you can also freeze the temperature sensors Tint and Text using a special aerosol (compressed air).

4.2.6 Checking the Active Cooling system (Air Conditioner)

The Air Conditioner starts cooling when the inside temperature / return air rises above the set limit (35 ºC) and turns off when the temperature falls accordingly. Testing the A/C unit is described in the following procedure:

Systems without hybrid cooling (only AC):

Step 1 Switch ON the AC unit circuit breaker FAC. If the temperature inside the cabinet is lower than 35 ºC, only the evaporator fan of internal air flow should start.

Step 2 Heat up the air in the AC unit inlet (internal air flow) using any heating device (i.e. heater gun) and check if the air conditioner starts the cooling – the condenser fan of the external air flow and compressor should start.

Step 3 If the temperature inside the cabinet is higher than 35 ºC, both airflows, internal and external of A/C unit, should be in operation – the AC unit should generate cold air.

Systems with hybrid cooling (AV+AC):

Step 1 Switch ON the AC unit circuit breaker FAC. If the temperature inside the cabinet is lower than 35 ºC, the AC unit will not start.

Step 2 Heat up by external heater the PSC 3 temperature sensor Tint. When the temperature is above the limit T4 (35 °C), the AC unit starts – only the evaporator fan of the internal air flow should be in operation.

Step 3 Heat up the air in the AC unit inlet (internal air flow) using an external heater and check if the air conditioner starts the cooling – the condenser fan of the external air flow and compressor should start.

Step 4 If the temperature inside the cabinet is higher than 35 ºC, both airflows, internal and external of A/C unit, should be in operation – the AC unit should generate cold air.


4.2.7 Checking the Heater

Testing the heater controlled by thermal switch TH is described in the following procedure:

Step 1 Switch ON the heater circuit breaker FH.

Step 2 Turn to the left the knob of the TH thermal switch to 0 °C – after that the heater should start.

Step 3 After the test, set the TH thermal switch back to the standard setting (+5 °C).

Testing the heater controlled by the PSC 3 controller is described in the following procedure:

Step 4 Switch ON the heater circuit breaker FH.

Step 5 Freeze the temperature sensors Tint using special aerosol (compressed air) to start heater operation when the temperature is below the limit TH (0 °C).
