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 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
fryer
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.
The analog controller has no timing features. The operator must monitor shake and pull times.
