ELECTRICAL OPERATION
COMPONENT FUNCTION
FRYER CONTROLS
Solid State or Computer
Cooking Controls
(D or C Models) . . . . . . . . . . . .
Controls fryer operation: Maintains shortening temperature, counts product
cook time(s) and signals the electronic alarm at the end of a cooking cycle. If
fryer is equipped with basket lift(s), controls the basket lift(s) operation.
Note:
By utilizing the same wiring harness connections, the two control types
are interchangeable between fryers.
Control Interface Board . . . . .
Provides the output signal interface from cooking control, to regulate heating
and basket lift(s) operation (if equipped). The board components consist of a
heat control Triac and two single pole N.O. relays.
Transformer . . . . . . . . . . . . . .
Supplies 24VAC to the cooking control circuit. If equipped with basket lift(s)or
filtering system, also supplies power for those control circuits. Transformer is
energized when supply voltage is connected.
Power Switch . . . . . . . . . . . . .
Supplies power to control circuit.
High Limit Thermostat . . . . . .
Prevents shortening from reaching temperatures over 460°F nominal (2
nd
high
limit; manual reset @ 445
/
F or below). Serves as a backup to the cooking
control’s high temperature alarm setting of 415
/
F (1
st
high limit; normal
operation resumes when temperature falls below this point).
Temperature Probe . . . . . . . .
Senses temperature of shortening. Converts the temperature into a resistance
valve which is monitored by the cooking control. The probe is an RTD
(resistance temperature detector) of the Thermistor type. As temperature
increases the resistance value decreases.
Drain Valve Interlock
Switch (DVI) . . . . . . . . . . . . . .
A magnetic reed switch (N.O.) mounted on the manual drain valve. When
valve is closed, supplies a drain valve position signal to the cooking control.
Prevents heating elements from being energized with the fry tank empty.
Tilt Switch . . . . . . . . . . . . . . . .
A magnetic reed switch (N.O.) mounted underneath the element head
assembly. Removes power from 1CON & 3CON to de-energize the heating
elements when the elements are raised.
1CON, 3CON and 2CON,
4CON Contactors . . . . . . . . . .
Supplies line voltage to heating elements.
Heating Elements . . . . . . . . . .
Produces heat that is transferred to the shortening.
R1 Heat Relay . . . . . . . . . . . . .
Supplies power to 2CON and 4CON contactor coils.
R2 Power Relay . . . . . . . . . . .
Supplies power to cooking control.
KLEENSCREEN FILTER CONTROLS
Filter Power Switch . . . . . . . .
Supplies 120VAC to pump motor. Filter valve switch or discard valve switch
must be closed (valve handle extended).
Pump Motor . . . . . . . . . . . . . .
Operates pump to circulate shortening through filtering system. Thermal
protector prevents motor from reaching excessive operating temperatures. If
tripped, the protector can be manually reset when motor temperature is
between 185
/
F to 228
/
F.
Filter Valve Switch . . . . . . . . .
Energizes pump motor to filter the shortening when switch is closed (valve
handle extended). Filter power switch must be turned on.
Discard Valve Switch . . . . . . .
Energizes pump motor to discard the shortening from filter tank when switch is
closed (valve handle extended). Filter power switch must be turned on.
R3 Filter Relay . . . . . . . . . . . .
Supplies power to pump motor.
