Model 290
The electric fryer requires two switching contactors: a primary and a
heat contactor. The primary contactor energizes (contacts close)
any time the POWER/PUMP switch is in the POWER position, and
the temperature of the shortening is below 420° F ( 215° C). The
high limit cuts power at the primary contactor if the temperature of
the shortening is above 420° F ( 215° C). The primary contactor
supplies power to one side of the heat contactor.
The heat contactor is controlled by the computer controller. When
the controller calls for heat, the heat contactor applies power to one
side of the heating elements. When the heat contactor and primary
contactor are energized (contacts closed) the electric heating
elements heat the shortening.
The photo shows a mercury heat contactor, but CE countries
will have an electromechanical heat contactor.
