Service manual

2. Protective function
The power supply circuits of +24VDC and +5VDC are equipped with overcurrent/overvoltage
protective functions. These protective functions automatically shut off the output voltage to pro-
tect the circuits when overcurrent or abnormal voltage results from troubles such as a short on
load. When these protective functions are activated and no DC voltage is output from the power
supply circuits, turn OFF the power, rectify the troubles on the loads, and then turn ON the
power again.
Wait about two minutes after turning OFF the power before turning it ON again.
