Contactors - Henny Penny LVE-202 Technical Manual

7-11. CONTACTORS

Oct. 2010
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 temperature limit module 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 the heating elements.
When the heat contactor and primary contactor are energized
(contacts closed), electric heating elements heat the shortening.

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
