Solution
How to connect a
remote display?
The remote MMIGRS2 display is connected to the controller via a
cable that can be ordered with different lengths�
When connecting the remote display, please remember to make a
short circuit of the two rightmost terminals on the terminal block
to the left of the cable connection – please refer to drawing�
When are alarms
cleared?
Normally alarms are automatically cleared as soon as the alarm
condition is cleared�
However, some safety alarms require that a safety restart delay has
to expire before the alarm condition is cleared and normal control
is resumed� This goes for the following safety alarms:
• High condensing pressure
• Low suction pressure
• High discharge temperature
Furthermore sensor alarms have a clearance delay of 10 minutes
(default), which means that the sensor has to be OK for 10 minutes
before the alarm is cleared� However normal control procedure will
be resumed as soon as the sensor signal is OK� The reason for the
delay is to avoid numerous alarms if a sensor has a bad electrical
connection�
Alarms can also be cleared manually by entering the alarm detail
picture and pressing the “X” button for 3 seconds� If the alarm
condition of a manually cleared alarm is still active the alarm will
be raised again�
Press the X (escape) button for 3 seconds
to clear alarms manually
