U.S. Navy Solid-State Analog Controller
ITEM DESCRIPTION
1 Power Switch – Controls electrical power to fryer.
2 Power-On Light – Indicates when electrical power to fryer is ON.
3 Heating Mode Light – Indicates when heating element is ON.
4 Trouble Light – Indicates over high-limit or problem in heat control circuitry.
5 Thermostat Control Knob – Sets desired frying temperature.
6 Hi-Limit Test Switch – Tests high-limit thermostat.
7 Second Hi-Limit Test Light – Indicates fryer is in second high-limit test mode.
The analog controller, illustrated above, is used to adjust and maintain oil at the temperature
indicated by the thermostat knob.
The fryer has two built-in high-limit protection features. If the temperature in the frypot reaches
approximately 410°F, the controller opens the heat relay circuit, turning the elements off. If the
temperature in the frypot reaches 450°F, a mechanical high-limit shuts off electrical power to the
elements. The operator should periodically test each of the high-limit protection features, using
the procedure at the end of this chapter, to verify that they are operating correctly.
