Operation of the electric circuit in detail
Compressor function:
See Circuit diagram (standard) (9822 0991 34)
(pages 24 and 26).
Generator function:
Turn switch S7 to position 1. The solenoid valve Y2
via the speed regulator controls the motor and allows
it to reach maximum speed (the normal control
system is switched off). Lamp H3 is activated and
sockets X1.1, X1.2, X1.3 are under tension.
The generator can be switched off by turning switch
S7 to position 0.
In the case of an insulation fault, the yellow LED on
the insulation monitoring relay K6 of the system is
activated. When the yellow LED of K6 is active, a
reset can only occur by halting and restarting the
assembly.
