Parameter:
HP circuit Pre-Alarm
Code:
PROT_3
Units:
Description:
Maximum value for high pressure in normal operation.
The objective of this alarm is to prevent activation of the general high pressure switch,
which would lead to the immediate shutdown of the installation.
For further information, see
Chapter 6.
The value of this parameter must be set below the activation pressure for the general high
pressure switch.
If the discharge pressure exceeds the value defined by this parameter, the compressor
stages will gradually be shut down with a time period defined by the parameter
TEMP_12.
If the high pressure pre-alarm occurs 5 times or more within one hour, the installation will
remain shutdown until it is reset manually.
Parameter:
HP circuit Pre-Alarm Diff
Code:
PROT_4
Units:
Description:
High pressure pre-alarm differential.
For further information, see
Chapter 6.
Parameter:
LP circuit Pre-Alarm
Code:
PROT_5
Units:
Description:
Minimum value for the suction pressure in normal operation.
If the pressure falls below this value, the Low Circuit Pre-Alarm will appear.
It is recommended that this parameter be set at a value above the activation pressure for
the general low pressure switch so as to inform the user that there is an anomaly in the
installation before the general low pressure switch acts.
