Normally the base voltage of Q502 is low and Q502 is not turn-on. The base of Q503 is minus voltage so Q503 is turn-on. Zener diodes D512 and 513 are short circuitry if Q503 is on. The collectors voltage of Q503 will be the same as zener diode D524, -10volts. This voltage leads fan motor to turn with low speed.
