Power Switch And Control Switch - Hoshizaki Modular Cubelet Serenity Series Service Manual

E. Power Switch and Control Switch
The power switch and control switch are used to control the operation of this appliance.
They are located on the control box.
1. Power Switch
The power switch has 2 positions, "OFF" and "ON." When the power switch is in the
"OFF" position (open), no power is supplied to the components. When in the "ON"
(closed) position, power is supplied to the control transformer and control board. The
control board then supplies 5VDC to the control switch for unit operation.
2. Control Switch
The control switch has 2 positions, "ICE" and "DRAIN."
When the control switch is in the "ICE" position (open), icemaking begins.
When the control switch is in the "DRAIN" position (closed), the drain valve energizes.
a) ICE
When the control switch is in the "ICE" position (open), the control board reads an
open circuit through the control switch contacts and starts the icemaking process.
b) DRAIN
When the control switch is in the "DRAIN" position (closed), the control board reads a
closed circuit through the control switch contacts and the drain valve energizes.
