Situation: No power being applied to heater; TCPL indicator OFF.
In this situation, the HTR indicator remains OFF. The power triac is protected
against continuous current overload with a 10 amp fuse. (Refer to Figure 6, Item
11.) If this fuse is blown, no power is available to the heater circuitry. In addition
to replacing a blown fuse, consider what may have caused the overload. The
heater and/or power triac may have developed a short circuit. This sort of occur-
rence is usually accompanied by burned wiring. Be certain that the heater doesn’t
exceed the power rating for the ITC (1000 watts).
It is the case that the situation described above can occur without blowing the
fuse. If this occurs, consider whether or not the load is inductive. Remember that
such loads cannot be switched with the ITC’s present circuitry.
The appropriate schematic diagram is supplied in this section. Should you require
any explanation of the circuitry, please contact the factory.
