Full Speed Mode
In full speed mode, IC300_pinK25 outputs constant 3.3V.
When Q606, Q607 and Q603 are turned on, Vo becomes approx 20V (approx.4V drops between R616, R617).
So the voltage between R425 is determined as follows
VL=Vo*R624/(R623+R624)=20*22K/(150K+22K)=2.5(V)
Since IC504_pinA3 is 3.3V and IC504_pinA2 is 2.5V, pin1_IC504 is always "H".
Consequently all Q606, Q607 and Q603 are always turned on, and then approx 20V is supplied to FAN motors.
Therefore FAN rotates with full speed.
6.9.3.3.
FAN stop
When IC300_pinK25 is "L", both Q606, Q607 and Q603 are turned off, then both FAN stop rotation.
6.9.3.4.
Rotation detect signal
During the FAN rotation, the pulse signal is output from pin 2 of FAN motors as the rotation detects signals.
If the period of the pulse is wider than predetermined value, it is judged that FAN error occurred.
Then display shows "Call Service 4".
