2.2.7 Factory settings
In the factory menu, the following fundamental parameters can be set:
Parameter Function Default Min. Max.
DEF fault delay The time that a fault on the digital inputs D,E or
F are overridden before the compressor is shut
down. 15s 1s 60s
Oil pressure The minimum oil pressure limit on which the
compressor is shut down. This is overridden by
oil pressure delay on start up 1 bar 0.3bar 2bar
Oil Pressure

overridden on start up after the star start. 10 s 1s 30s
1
