lated power supply, +S(+24), -S (GND)
with the tester. Is the voltage +24 V?
NO Replace the regulated power supply.
Elevator motor
4

PCB Unit CN8-4 (+) and CN8-3 (-) with
the tester at the timing of the elevator
motor operation. Is the voltage +24V
whether the elevator motor relay con-
nector is inserted or not?
YES Replace the elevator motor.

limit sensor 0V at the time of pho-
topassing and 5V at the time of pho-
tointerrupting?
YES Replace the main PCB Unit.
