If the screw compressor output temperature exceeds the alarm limit (110°C / 230°F), the LED (8) turns on and the relative pictogram appears
intermittently. Press key (14) until the current output temperature of the screw compressor appears:
The screen shows that the screw compressor output temperature is 112°C / 234°F.
Using keys (14) and (15) it is possible to scroll through the various screens to check the status of the other parameters.
Stop the compressor by pressing key (1) and wait for the compressor to stop.
Disconnect the power upstream, isolating the unit.
ATTENTION:
the unit must be isolated from the mains.
Inspect the compressor to identify and eliminate the fault.
The alarm message disappears once the fault conditions have been eliminated.
Dew point temperature
For compressors with incorporated dryer, if the dew point temperature exceeds the alarm limit (non-programmable value), LED (8) turns on and the
relative pictogram appears intermittently
The screen shows the dew point temperature.
Press key (14) until the current dew point temperature appears:
The screen shows that the dew point temperature is 22°C (72 °F).
Using keys (14) and (15) it is possible to scroll through the various screens to check the status of the other parameters.
Stop the compressor by pressing key (1) and wait for the compressor to stop.
Disconnect the power upstream, isolating the unit.
ATTENTION:
the unit must be isolated from the mains.
Inspect the compressor to identify and eliminate the fault.
The alarm message disappears once the fault conditions have been eliminated.
Fail stops
The compressor stops due to failure in the following cases:
-
The temperature at the screw compressor outlet exceeds the fail stop limit value
-
Error in supply pressure sensor
-
Inverter alarm
