4.2.3 Compressor
The speed and thereby the capacity of the compressor is set using the Requested speed parameter.
During start up, the compressor can be run at a lower speed, Start speed , than Requested speed.
The duration of the period running at Start speed is set using the Start time parameter.
The compressor is protected against operation below minimum speed. Lubrication of the compressor
will be very poor at excessively low speed and therefore low speed operation can lead to destruction
of the compressor. Speed limits are: min 1850 rpm; max speed 4300 rpm.
If the compressor speed falls below the minimum or exceeds the maximum speed, the compressor will
stop and an alarm
Min speed failure or Max. speed failure will be sent. The compressor will try to restart
after the set Restart time . The Restart time default is 60 sec.
The fans will continue to run.
