8.2 Service Mode
After selection of the pack controller Service Mode (menu 8), all compressors and fan outputs are reset step by
step.
Then all controller functions are inactive so that each digital and analogue output can be set manually. The
controller registers the
Service Mode by the entry of a message in the log memory. Transmission is performed
according to priority selection.
8.3 Display of the Operating States
Some rows of the display have additional symbols before the operating states of the system measured value.
The following additional symbols are displayed.
Display of the suction pressure trend:
Shows whether compressor capacity stages should be loaded, unloaded or not switched after expiry of the
delay times.
Display of the gas cooler outlet temperature trend:
Shows whether compressor capacity stages should be loaded, unloaded or not switched after expiry of the
delay times.
The operating modes "subcritical" and "transcritical" as well as the trend display are also shown for the
controller:
In the service mode the switching commands to the relays or the specifications to the analogue outputs
(voltage 0..10 V or current 4..20 mA) are performed immediately!
The digital and analogue inputs (motor overload cut-out, oil pressure difference switch, pressure
transmitter etc.) are not taken into account.
