Explanation
The regulator does not accept illogical settings, e.g. if the unloading pressure is
programmed at 7.0 bar(e)/101 psig, the maximum limit for the loading pressure changes
to 6.9 bar(e)/100 psig. The recommended minimum pressure difference between loading
and unloading is 0.6 bar/9 psig.
Is the time for which the signal must exist before the compressor is shut down. If it is
required to program this setting to another value, consult your Customer Centre.
The compressor will not start if this level is exceeded at the moment of starting. If the level
remains too high for 30 seconds, the message "Start failure" will appear on the display.
