Alarm limit for P0
Delay time before alarm for "P0 max. alarm °C"
Alarm limit for min. superheat
Alarm limit for max. superheat
Time delay before alarm for "SH min limit" and "SH min limit"
Time delay before restart of compressors
(Applies to the functions: "Sd max limit", "Pc max limit" and "P0 min limit")
Liquid injection in the suction line. Set superheat value where liquid injection is to
start.
Liquid injection in suction line. Set Sd temperature where liquid injection is to start.
Select if alarm monitoring is required on charge temperature S4
High alarm limit for cold brine charge temperature
Delay on high charge temperature under normal regulation
Delay on high charge temperature on start or during defrost
Low alarm limit for cold bring charge temperature
Delay on low charge temperature
When "ON", the controller is in alarm condition.
Actual temperature for compressor control
Actual cold brine supply temperature measured with S4 temp. sensor
Actual cold brine return temperature measured with S3 temp. sensor
Suction pressure in °C. (Measured with the pressure transmitter)
Actual reference temperature for compressor control
Cut-in compressor capacity in % (of total capacity)
Reference for compressor capacity (deviations may be due to time delays)
Actual temperature for control sensor (Pc or S7)
Actual warm brine temperature for S7 media sensor
(Only used if S7 sensor is selected as regulation sensor)
Condensing pressure in °C. (measured with the pressure transmitter)
Actual reference temp. for condenser capacity
(incl. external reference signal, if any)
Cut-in condenser capacity in % (of total capacity)
Reference for condenser capacity
Alarm status on the function defined as a DI1 alarm
ON: Alarm is active
OFF: No alarm, normal situation
As above, but for the alarm functions 2 to 8
Main switch:
Time delay for the alarm "DI 1 Alarm"
As above, but for the alarm functions 2 to 8
When "ON", the controller is in alarm condition.
