4.3 Termination of the RS-485 MODBUS line

To reduce reflections on the signal transmitted along the cables connecting the devices to a RS-485 network it is necessary to

terminate the line ONLY at the first and last element in the network.

To terminate the line, it will be sufficient to place EV3 CHIL micro-switch 1 in position ON. Do not touch micro-switch 2.

When using EVD CHIL, place micro-switch 1 in position ON.

4.5 Precautions for electrical connection

- Do not use electric or pneumatic screwdrivers on the terminal blocks of the devices.

- If the devices have been moved from a cold to a warm place, the humidity may cause condensation to form inside. Wait

about an hour before switching on the power.

- Make sure that the supply voltage, electrical frequency and power of the devices correspond to the local power supply. See

the section TECHNICAL SPECIFICATIONS.

- Disconnect the devices from the power supply before doing any type of maintenance.

- The devices must be fed by power of the same phase as that feeding any module with a phase-cutting command signal.

- If using triac digital outputs, we recommend connecting a noise filter. The heat sink might reach very high temperatures,

do not touch it.

- Connect the devices to an RS-485 network using a screened cable with twisted pair for the signal and a third separate

conductor for the reference (for example the BELDEN 3106A cable). NB: do not connect the cable shield to the reference

(GND)

- Connect the power cables as far away as possible from those for the signal.

- Do not use the devices as safety devices.

- For repairs and for further information on the devices, contact the EVCO sales network.

8 ALARMS

8.1 Initial information

All the alarms re-arm automatically except for:

- Antifreeze alarm: manual re-arm

- Low pressure alarm: manual re-arm if, in an hour, the number of events is higher than parameter AL01

- Flow alarm: manual re-arm if, in an hour, the number of events is higher than parameter AL07

Prolonged pressure of the On/stand-by key resets all the manual re-arm alarms and the counters of the events number per hour.

8.2 List of alarms

The table below shows the meaning of the device’s various alarm codes.

CODE DESCRIPTION

High pressure alarm

The alarm is activated both by the maximum pressure switch and when the value of the condensation probe exceeds the

AHP1

ALP1

threshold set by AL05. The alarm is deactivated when both conditions return to normal.

Main results

- The compressor is switched off.

Low pressure alarm

This alarm is activated when the pressure switch detects low pressure. It is deactivated when the pressure switch is re-

armed.

The alarm activates with a delay of Al102 from when the compressor is switched on.

Main results

- The compressors and fan are switched off.

AtC1

AdS1

AtF1

AFr1

Compressor thermal alarm

The alarm is activated if the input configured as compressor thermal alarm is active. It deactivates if the input is

inactive.

Main results

- The compressor 1 switches off.

Compressor 1 discharge alarm

The alarm is activated when the value detected by the probe configured as compressor discharge temperature rises

above the value expressed by AL17. It deactivates when the temperature falls below the value expressed by AL17 –

AL18.

Main results

- The compressor is switched off.

Fan thermal alarm

The alarm is a ctivated if the input configured as fan thermal alarm is active. It dea ctivates if the input is inactive.

Main results

- The compressors and fan are switched off.

Antifreeze alarm

The alarm is calculated on the minimum temperature reading of the input and output water probes: the alarm is

activated when the minimum value is below AL12; it is deactivated when the value is above AL12+AL13. The alarm is delayed for a period equalling AL11 from when it is switched on in hot mode.

Main results

- The compressor and fan are switched off.

It reverts to manual re-arm if the number of alarm events in an hour exceeds AL07.

Main results

- All functions switched off.

High temperature alarm

This alarm is activated when the input water temperature exceeds Al15 for a period longer than Al16. It is deactivated

when the temperature is lower than Al15-Al13.

Main results

- Compressors switch off

Probe alarms

The alarm is activated in the following situations:

- when a probe short circuits or is interrupted

- if the upper or lower limits set for a probe are exceeded

Main results

- All functions switched off.
