7-11. CONTACTORS

Heat Safety
May 2009
The open fryer requires two switching, 24V contactors per vat:
a primary and a heat contactor. The primary contactor energiz-
es (contacts close) any time the main power switch is in the ON
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 button is pressed and 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.
Checkout:
1. Remove electrical power supplied to the fryer.
To avoid electrical shock or property damage, move the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2. Remove the top, rear panel.
3. Label and remove wires from contactors and perform a
check on both contactors as follows:
Test Points
From 30 to 34
From 31 to 35
From 32 to 36
From 33 to 37 (coil)
To avoid electrical shock, make connections before
applying power, take reading, and remove power
before removing meter leads. The following checks
are performed with the wall circuit breaker closed
and the main power switch in the ON position.
