ELECTRIC FRYERS - ELECTRICAL OPERATION

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.

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.

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.

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.

6.Oil is pumped back to vat.

7.Close the return valve.
