CHAPTER 7 EXTERNALS/AUXILIARY MECHANISMS
D. Protection Mechanisms for the Power Supply Circuit
The composite power supply PCB is equipped with an overcurrent detection circuit;
if a short circuit occurs in a load for some reason, the protection mechanism is activated
to stop the output.
When the output is cut out, you may reset the output by opening the front door to turn
off the door switch, correcting the load, and turning on the door switch and power switch
(SW829) once again.
Caution:
Be sure to disconnect the connector (J4) of the fixing heater before resetting the
output.
Repeated short circuiting and resetting can cause the built-in fuse (FU101) to blow.
