Service - Danfoss AK-CC 550A User Manual

Configuration of alarm relay
The alarm relay will be activated upon an alarm signal from the following groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input enabled for alarm
16 - Defrosting alarms
32 - Miscellaneous
64 - Injection alarms
The groups that are to activate the alarm relay must be set by using a numerical value
which is the sum of the groups that must be activated.
(E.g.: a value of 5 will activate all high temperature alarms and all sensor error and 0
will cancel relay function
