C7000 INSTRUCTIONS fOR A/C UNITS
The corresponding commands:
With a condensation pressure sensor (either part of G-valve or separate option)
high pressure alarms can be equally managed for the same reasons as LP
alarms.
You can limit the number of allowed compressor restarts in "RESTARTS"
➏
within a time space you can adjust in the left column of the sixth line. You can
define the time space in the right column of the same line
➏b.
If the threshold
➏a of the HP within this time space is excessed at least the
adjusted number of times, the measure which you have adjusted in "mode"
➐ is
taken.
off - 0: A high pressure alarm is triggered and the compressors of this refriger-
ant circuit are stopped. A compressor restart is possible after the reset
of the alarm.
on - 1: The high pressure management is listed in the event-log and the com-
pressors of this refrigerant circuit are stopped. After the compressor
pause has elapsed, the compressors can be started again.
For A/C units with more than one compressor per refrigerant circuit the follow-
ing is valid:
Compressor 1, 3 and 5 are assigned to the first refrigerant circuit, compressor
2, 4 and 6 to the second refrigerant circuit.
The parameters, which concern the LP- and HP management of compressor 1
are also valid for compressor 3 and 5 and automatically change after the set-
ting of compressor 1 in the menu of compressor 3 and 5 also.
Such an interconnection also exists between compressor 2, 4 and 6.
NOTICE
An LP or HP management is possible for on/off-compressors only.
