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. Time
relay K7 disconnects the sockets from the generator
during 4 sec, after which the sockets X1, X2, X3 are
under tension.
The generator can be switched off by turning switch
S7 to position 0.
If switch S7 is turned on, lamp H4 and ecologiser E1
are activated. E1 senses continuously the current to
the sockets. If no current is sensed, time relay K8 is
activated. This time relay deactivates the solenoid
valve Y2 so that the speed regulator is again
controlled by the normal compressor control system.
When in this condition E1 senses current to the
sockets, the solenoid valve Y2 is re-activated
immediately by K8. Time relay K7 disconnects the
sockets from the generator during 4 sec, after which
the sockets X1, X2, X3 are under tension.
