For scroll
Limitation of capacity during time period. There is no limit if the setting in 100%.
For "Scroll" and "Stream"
Define whether the controller should monitor the discharge gas temperature Sd from a
digital scroll or a stream compressor (NTC 86K or Pt 1000 Ohm).
For scroll and Stream and yes to "Comp.1 Sd temp"
Set the maximum Sd temperature
Compressor timers
Min. On-time for first compressor
Set a forced On-time here during which the compressor will remain in operation before it
can be switched off again. The setting is to prevent incorrect operation.
To prevent a compressor breakdown, the setting must be made in accordance with the
requirements of the compressor supplier.
Min. Off-time for first compressor
Set the forced Off-time during which the compressor must be off before it can be switched
on again. The setting is to prevent incorrect operation.
Min. period of time for re-starting the first compressor.
Set the forced Off-time during which the compressor must be off before it can be switched
on again. The setting is to prevent incorrect operation.
To prevent a compressor breakdown, the setting must be made in accordance with the
requirements of the compressor supplier.
Delay time before compressor no. 1 cut out for reasons of safety
The time begins when a signal is received on the safety input for the compressor
Min. On-time for remaining compressors
Set a forced On-time here during which the compressor will remain in operation before it
can be switched off again. The setting is to prevent incorrect operation.
Min. Off-time for remaining compressors
Set the forced Off-time during which the compressor must be off before it can be switched
on again. The setting is to prevent incorrect operation.
Min. period of time for restarting remaining compressors
Set the forced Off-time during which the compressor must be off before it can be
switched on again. The setting is to prevent incorrect operation.
Delay time before compressors cut out for reasons of safety
The time begins when a signal is received on the safety input for the compressor
Compressor status
Read the Sd temperature of the compressor here.
Read the operating status for compressor 1 here. The following information may appear:
Power up=startup. Off= compressor stoppt. Manual ctrl=compressor manual controlled.
Cut out on safety=stoppt due to signal on DI-input. Restart timer=await timeout of time
delay. Ready=ready to start. Min OFF timer=await time out of time delay. Min. ON timer=await
timout of time delay. Full load=compressor works 100%. Running=compressor running.
Disabled=stoppt due to service

Compressor service
compressor.
No = Normal regulation
Yes = Regulating is carried out without this compressor, and no alarms are generated by it.
