ELECTRIC FRYERS - ELECTRICAL OPERATION
18
4. Shortening temperature reaches set
temperature.
A. Computer turns off heat output and control
relay R2 de-energizes.
B. Power is removed from 2CON and 4CON.
5. Computer cycles heat output on temperature.
6. If the first high limit (410 F) trips, the display
will indicate “HI TEMP”.
NOTE:
For a full vat, the fryer will shut down and
become inoperable. For a split vat, only the vat
which experienced the failure becomes inoperable.
7. If the second high limit (435 F) trips or the tilt
switch operates, the control relay R1 is de-
energized removing 24 VAC power from pin 1
(full vat), pin 1 or pin 2 (split vat because its
control relay is de-energized). The display will
indicate “OFF” for a full vat and become
inoperable . If a split vat, “OFF” will be
displayed for the vat which experienced the
failure and become inoperable.
BATTERY AND INTER
PLUMB FILTER SEQUENCE
OF OPERATION
NOTE:
A battery of fryers equipped with optional
interplumbing connects the vats to a common drain.
Each vat has an individual drain valve. These
valves should only be opened one at a time.
1. Conditions
A. Empty filter in position and connected as
outlined in filter Instructions manual.
B. All drain valves and return valves closed.
2. Open desired vat drain valve.
3. Oil drains into filter.
4. Close drain valve.
5. Open return valve for vat oil is to be returned
to.
A. Return valve switch normally open
contacts close energizing 24 VAC control
relay IPR1.
B. Control relay IPR1 normally open contacts
close to provide line voltage to filter motor.
6. Oil is pumped back to vat.
7. Close the return valve.
A. Return valve switch contacts open.
B. Control relay IPR1 unenergizes.
8. Filter motor stops.
BASKET LIFT SEQUENCE
OF OPERATION
1. Conditions
A. Fryer at operating temperature.
B. Basket lift in raised position.
C. Basket lift micro switch operated, normally
open contacts closed.
D. BLR1 control relay unenergized.
2. Power is present at one side of gear motor and
contact 5 of BLR1 control relay.
3. When either the Push To Time button (solid
state models) or the Start button (computer
control models) is pressed, BLR1 relay is
energized closing contacts 5 and 3.
4. Power flows through BLR1 contacts 5 and 3
and normally open contacts of micro switch.
5. Motor runs until lift is lowered and cam
unoperates micro switch.
6. Micro switch normally open contacts open
removing power from motor.
7. Timer (solid state control) or cook cycle
(computer control) is complete and power is
removed from BLR1 control relay.
8. BLR1 normally closed contacts 5 and 1 close
suppling power through micro switch normally
closed contacts.
9. Motor runs and lift raises until cam operates
micro switch opening the normally closed
contacts and stopping the motor.
10. Cycle is repeated.
