TESTING TWO-STAGE OVERHEAT SYSTEM
Disconnect the power cord from the receptacle. Remove the top front panel
by removing the six retaining screws. Reconnect the power cord to the
receptacle.
Set the drying control on the STC1 Controller to C and the temperature to
45ºC.
Gradually reduce the temperature control setting. When the temperature
setting equals the temperature indicated by the temperature display, the
heater will switch of. This can be verified by observing the C1 Contactor.
When this contactor de-energizes, the heat is off. Reduce the temperature
control further and the compressor will switch off when the temperature
setting is below 5º below the temperature display. This can be verified by
observing the C2 contactor. When this contactor de-energizes, the
compressor is off (See Figure 9).
Should you have any problems resulting from testing your LD3000 or STC1
Controller, contact the Service Department of assistance.
Warning:
DO NOT reach into the electrical panel with your hand or any
tool. This may result in a severe electrical shock or death.
