CONTROL OPTIONS
45 Series fryers may be equipped with thermostat controllers, analog controllers, digital controllers,
basket lift timers, or Computer Magic III computers.
In fryers equipped with thermostat controls, the fryer and melt cycle are turned on and off by means
of rocker switches and the temperature is set by means of a knob connected directly to the frypot-
mounted thermostat. These units have no interface board. In this type of unit, when the melt cycle
switch is placed in the ON position, the fryer stays in the melt cycle mode until the switch is manu-
ally placed in the OFF position, even if the frypot is at setpoint temperature.
Fryers equipped with other types of controllers have an interface board located in the component
shield behind the control panel.
INTERFACE BOARDS
The interface board provides the link between the controller/computer and the fryer's individual
components without requiring excessive wiring, and allows the controller to execute commands from
one central point. When built, depending upon the configuration of the particular fryer, any one of
three different boards may be used. Regardless of the particular board installed when the fryer was
built, P/N 806-3548 is the universal replacement part.
