CEF40/75 FRYER - ELECTRICAL OPERATION
ELECTRICAL OPERATION
COMPONENT FUNCTION
Contains components used to set and control temperature.
Engages contactors to supply power to heating elements.
Supplies power to control circuit for fryer operation.
Selects type of shortening being used (liquid/ solid).
Green LED located on control box assembly. Indicates start switch has been pressed.
Yellow LED located on control box assembly. Indicates heating elements are on or off.
LED cycles on and off.
Used to set the desired operational temperature.
Green lamp located on right-side of chassis. Indicates power switch has been pressed.
Yellow lamp located on right-side of chassis. Indicates if heating elements are on or off.
Lamp will cycle on and off.
Used to drain tank.
Magnetic reed switch mounted on drain valve. 24VAC power to temperature controller
board passes through switch. When drain valve is open, 24VAC power is removed from
temperature controller board. This prevents heating elements from being energized when
valve is open.
Used to heat shortening. Cycles on and off as to maintain desired temperature.
Used to limit operational temperature. Opens and removes power if shortening
temperature exceeds 460°F. It has a pushbutton switch that must be pushed to reset it.
The switch cannot be reset until shortening temperature drops below 415°F.
It is wired in series with tilt switch and removes power from power contactor coil when
open.
Magnetic switch mounted underneath element head assembly. Monitors heating
elements position (lowered [closed] or raised [open]).It is wired in series with high
temperature switch and removes power from power contactor coil when open.
Monitors shortening temperature.
Protects fryer electrical circuits from damage.
Supplies power to heat contactor coil.
Controls power to heating elements.
Provides 24VAC operational power to control box assembly / control circuit.
Protects fryer electrical circuits from damage.
Connects factility power to unit.
