10.2.4 Operation
10.2.4.1 Remarks
Local start/stop function
All local start and stop functions on the control panels of the compressors are disabled, except for the
emergency stop buttons which remain active.
Clock functions
In case time-based automatic start/stop commands were programmed in the regulators of the participating
compressors (via menu Clock function), these commands will not be taken into account.
Variable speed compressors
In case one or more IVR compressors are participating, one IVR will act as control IVR:
1. • The set point of the control IVR will be in the middle of the net pressure band.
1. • The Indirect stop level will equal the maximum level of the net pressure band.
1. • The Direct stop level will equal the sum of the new Set point and the programmed direct stop level
of the control IVR compressor; the direct stop level must be higher than the Indirect stop level.
Example:
Pressure band levels programmed in the master regulator: max. 8.0 bar(e) - min. 7.0 bar(e) and Direct stop
level programmed in the regulator of the variable speed compressor: 1 bar
In LAN configuration, the IVR compressor will have a Set point of 7.5 bar(e), an Indirect stop level of 8.0
bar(e) and a Direct stop level of 8.5 bar(e).
