switch as needed.

 

 

Control, conveyor

Check for supply voltage to conveyor control at

 

 

terminals #1 (AC) and #2 (AC). If no voltage is present,

 

 

trace wiring back to conveyor switch. If AC voltage is

 

 

present, check for DC voltage output at terminals #3

 

 

(A-) and #4 (A+). If there is AC voltage in, but no DC

 

 

voltage out of the conveyor control. Replace the

 

 

conveyor control. If there is D.C. voltage output,

 

 

proceed.

 

 

Fuse, 2 Amp

Check, replace if necessary.

 

Fuse holder

Check for D.C. voltage supplied to fuse holder. If no

 

 

voltage is present, trace wiring back to conveyor

 

 

control. Check fuse holder, replace if necessary.

 

Switch, conveyor reversing

Check for D.C. voltage supplied to the reversing switch.

 

 

If no voltage is present, trace wiring back to the fuse

 

 

holder. Check continuity between switch terminals.

 

 

Replace switch as needed.

 

Conveyor motor

Check for D.C. voltage to the conveyor motor. If no

 

 

voltage is present, trace wiring back to the reversing

 

 

switch. If voltage is present and the motor will not run,

 

 

check the motor windings for opens or shorts. Check

 

 

motor brushes for excessive wear. Replace motor

 

 

brushes as needed.

 

 

If any of the above fails, replace conveyor motor.

 

Conveyor

Check for any mechanical problems in the conveyor

 

 

assembly. Check for damaged or torn belting. Check

 

 

conveyor shaft bearings for damage or excessive wear.

 

 

Repair or replace conveyor components as needed.

Conveyor speed varying or

Power supply

Check for a steady supply voltage to the conveyor

intermittent

 

control. If voltage is not steady, trace back to power

 

 

supply.

 

 

Control, conveyor

Check for a steady DC voltage output at terminals A+

 

 

and A-. If voltage is not steady, proceed. Check for

 

 

5 VDC output from the conveyor control at terminals

 

 

+5V(red) and COM (black). If there is no voltage output,

 

 

replace the conveyor control. If there is DC output,

 

 

proceed.

 

 

Motor, conveyor

Check conveyor motor and gearbox for any visible

 

 

damage. If there is apparent damage, repair or replace

 

 

conveyor motor. Check motor brushes for excessive or

 

 

abnormal wear. Replace motor brushes as needed.

 

Hall effect sensor/magnet

Check to be sure that the Hall effect sensor and

 

 

magnet are mounted on the motor. Check for any

 

 

visible damage to the Hall effect sensor and magnet. If

 

 

there is visible damage, repair or replace as needed. If

 

 

there is no visible damage, check for a frequency

 

 

output from the hall effect sensor at terminals SIG

 

 

(white) and COM (black).

 

 

Readings should be as follows:

 

 

2:15 cook time

56 Hz. approx.

 

 

5:00

25 Hz. approx.

 

 

10:00

13 Hz. approx.

 

 

16:00

8 Hz. approx.

 

 

If these readings are not achieved, replace the Hall

 

 

effect sensor/magnet
