The following information provides a sequential list of
electrical components that L--1 power travels through
to initiate various operations.
Auto Mode of Operation:
L--1 power travels through the power switch, beater
overload switch, the compressor high pressure
cut--out switch, the overload terminal (OL) on the
power board, the BTR terminal of the power board, and
energizes the coil of the beater motor contactor.
L--1 power travels through the power switch, beater
overload switch, the compressor high pressure
cut--out switch, the overload terminal (OL) on the
power board, the COM terminal of the power board,
and energizes the coil of the compressor contactor .
L--1 power travels through the power switch, beater
overload switch, the compressor high pressure
cut--out switch, the L--1 terminal of the power board,
the MIX terminal of the power board, and energizes the
hopper refrigeration compressor and condenser fan.
Wash Mode of Operation:
L--1 power travels through the power switch, beater
overload switch, the compressor high pressure
cut--out switch, the overload terminal (OL) on the
power board, the BTR terminal of the power board, and
energizes the coil of the beater motor contactor.
Pump Mode of Operation:
L--1 power travels through the power switch, beater
overload switch, the compressor high pressure
cut--out switch, the overload terminal (OL) on the
power board, the PUMP terminal of the power board,
and energizes the coil of the pump motor .
