Inlet air temperature of the condenser
is too high (A/C units).
The air temperature measured at the
inlet of the condenser may not exceed
the limit indicated in the operational
range (working envelope) of the chiller
(A/C units).
Check the location where the unit is
installed and check that there are no
short circuit of the hot-air blown from
the fans of the same unit, or even from
fans of next chillers (Check IOM for
proper installation).
One or more condenser fan turning in
wrong direction.
Check for correct phases sequence
(L1, L2, L3) in the electrical
connection of the fans.
Mechanical high-pressure switch is
damaged or not calibrated.
Check for proper operation of the
high-pressure switch.

5.6.19 No Pressure At Start Alarm
This alarm is used to indicate a condition where the pressure at the evaporator or at the condenser is lower than 35kPa,
so the circuit is potentially empty of refrigerant.
Symptom

Solution
Circuit status is Off.
The compressor does not start.
Bell icon is moving on controller’s
display.

Check transducers calibration with an
appropriate gauge.
Check transducers cabling and
readout.
Check refrigerant charge and set it to
the proper value.

5.6.20 No Pressure Change At Start Alarm
This alarm indicates that the compressor is not able to start or to create a certain minimum variation of the evaporating or
condensing pressures after start.
Symptom
Cause
Solution
Circuit status is Off.
The circuit is stopped.
Bell icon is moving on controller’s
display.

Compressor cannot start
Check if the start signal is properly
connected to the inverter.
Compressor is turning in wrong
direction.
Check correct phases sequence to
the compressor (L1, L2, L3) according
to the electrical scheme.
Inverter is not properly programmed
with the right direction of rotation
Refrigerant circuit is empty of
refrigerant.
Check circuit pressure and presence
of refrigerant.
Not proper operation of evaporating
or condensing pressure transducers.
Check proper operation of
evaporating or condensing pressure
transducers.

5.6.21 Overvoltage Alarm on input voltage
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.
