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, X2, X3 are under tension.
The generator can be switched off by turning switch
S7 to position 0.
An insulation fault is detected when a leakage current
is flowing. Contactor K5 will no longer be exited
through the earth faultcurrent relay N13.
