6.1.7.13 High Motor Current Alarm
This alarm indicates that the compressor absorbed current is exceeding a predefined limit.
Symptom

Solution
Circuit status is Off.
The compressor does not load
anymore or even unload, circuit is
stopped.
Bell icon is moving on controller’s
display.

The ambient temperature is too high.
Check the unit selection to see if the
unit can operate at full load.
Check if all fans are operating
properly and are able to keep the
condensing pressure at the proper
level.
Clean condenser coils to allow a
lower condensing pressure.
The wrong compressor model has
been selected.
Check the compressor model for this
unit.
6.1.7.14 Low Pressure Ratio Alarm
This alarm indicates that the ratio between evaporating and condensing pressure is below a limit
which depends on compressor speed and guarantees the proper lubrication to compressor.
Symptom

Compressor is not able to develop the
minimum compression.
Check fan setpoint and settings, it
could be too low.
Check compressor absorbed current
and discharge superheat.
Compressor can be damaged.
Check the correct operation of suction
/ delivery pressure sensors.
Check the internal relief valve didn’t
opened during previous operation
(check the unit history).
Note:-
If the difference between delivery and
suction pressure exceed 22bar, the
internal relief valve open and need to
be replaced.
Inspect the gate rotors / screw rotor
for possible damages.
6.1.7.15 Overvoltage Alarm
This alarm indicates that chiller supply voltage exceeded the maximum limit which allows proper
operations of the components. This is estimated looking at the DC voltage on the inverter which
depends of course from the main power.
Resolution of this fault requires a direct intervention on the power supply of this unit.
Direct intervention on the power supply can cause electrocution, burns or even death. This action
must be performed only by trained persons. In case of doubts contact your maintenance company.
