Computer Control Board Diagnostics

ELECTRIC FRYERS - ELECTRICAL OPERATION

NOTE: The computer control is also used on other equipment and is capable of displaying many different prompts. Therefore some prompts not applicable may display when a problem occurs in the wiring harness. Since the computer is looking for either 24 VAC or 24 VAC ground on particular pins, an open connection can cause a non applicable prompt to appear. Refer to “Computer Control Harness Pin-outs Chart”

For operator programming and operation refer to that section in the Instructions Manual.

Diagnostics is divided into two areas, “operation” and “service”. Operation mode is the usual mode of fryer operation. Service mode is intended to give the service person more information regarding the nature of the failure. In either mode the unit operates normally until an error occurs. In that case what is displayed will be different. The chart below shows what is displayed for both “operation” and “service” modes.

Service mode is entered by pressing the product 3 and product 4 keys while turning on the power to the fryer computer. Once in service mode you can only exit it by turning off the power switch.

The following displays/system responses will be given for the noted failure conditions.
