Scotsman FME2400RH Скачать руководство пользователя страница 9

COMPONENT DESCRIPTION: Control Box

Circuit Board: Controlling the ice machine through
sensors and relays. The sensors are: ice level, and
water level. The relays are for the gear motor
(with a built in time delay to clear the evaporator of
ice when the unit turns off) and for the liquid line
valve.
Transformer: Supplies low voltage to the circuit
board.
On/Off Switch: Manual control for that side of the
machine.
