TIC LEXION 500 Electric System
03/05 Lex-e-38a 38a-3
Description of function:
Compressor-type air
conditioner
The two closed gas-pressure switches (Z22/Z23) must supply relay K24
with earth in order to allow the function of the electro-magnetic clutch
(Y32). When the fan switch (S28) and the thermostat switch (Z24) are
closed, relay K24 is actuated and thus, electro-magnetic clutch (Y32) is
also supplied with power by relay K52/87.
If the earth signal fails due to one of the two gas-pressure switches
(Z22/Z23), the electro-magnetic clutch (Y32) disengages and this fault is
displayed in terminal (A30).
