Unit Description
38
Overload Relay—Manual Reset (Model 50):
An
overload relay protects the standby electric motor. The
overload relay opens the circuit to the electric motor if the
motor overloads for any reason (e.g., low line voltage or
improper power supply) while the unit is on electric standby
operation. The microprocessor will record Alarm Code 90.
Press the reset button on the high voltage tray to reset the
overload relay. The high voltage tray is located behind the
lower access panel on the compressor side of the unit.
Smart FETs:
Smart FETs in the controller interface board
protect some circuits and components from an overcurrent
condition.
Fuses:
A number of fuses, located on the interface board,
protect various circuits and components. The interface board is
located inside the control box. Refer to the appropriate
Microprocessor Controller Diagnostic Manual for more
information about the fuses.
