Conveyor Control(Stepper)

Check for 120 VAC supply to primary of

 

Transformer

transformer, if voltage is not present, trace wiring

 

 

back to the fuse-holder. If voltage is present, check

 

 

for output voltage from the transformer secondary.

 

 

NOTE: this control transformer outputs (2)

 

 

secondary voltages. Red Leads 29 VAC Brown

 

 

Leads 10 VAC If BOTH secondary voltages are not

 

 

present, replace the transformer.

 

Speed Adjustment

This is a 0 to 50k ohm,10 turn potentiometer. WITH

 

Potentiometer

POWER OFF: remove the 3 pin potentiometer

 

 

cable plug from the motor control board. With a

 

 

digital multimeter, check the ohm reading across

 

 

the red lead to the black lead, this reading should

 

 

be 50k ohms ± 5% as the potentiometer is rotated

 

 

through its 10 turn rotation. Place the meter leads

 

 

on the red lead and white lead. Rotating the

 

 

potentiometer slowly, from low to high, the meter

 

 

should show an even transition from 0 to 50K ohms

 

 

± 5% through the 10 turn rotation of the

 

 

potentiometer. There should be no dead or open

 

 

spots through the 10 turns of the potentiometer.

 

 

Check all three leads to ground. There should be

 

 

no continuity to ground. If any of the above checks

 

 

fail, replace the potentiometer.

 

Conveyor Motor(Stepper)

NOTE: if the conveyor drive motor becomes

 

Control

jammed or begins to run at an uncontrolled speed,

 

 

the conveyor motor will stop running. To reset, turn

 

 

off the conveyor switch, wait 10 seconds, turn the

 

 

conveyor switch on. If the motor does not run after

 

 

attempting re-set, check for 2-29 VAC across the

 

 

motor terminals 1 to 2 and 3 to 5 on the conveyor

 

 

motor control. If voltage is not present at both sets

 

 

of terminals, replace control

 

Conveyor Drive (Stepper)

Check the drive sprocket on motor out-put shaft to

 

Motor

insure that it is tight.. Check motor windings –

 

 

measurements should be approximately 2 ohms.

 

 

Terminal 1-5, 2-6, 3-7, 4-8 WITH POWER OFF:

 

 

Turn the motor shaft to check for jammed gear box.

 

 

If motor shaft will not turn, replace conveyor

 

 

drive(stepper) motor.

Time/Temp Display

12.6 VAC Power Supply

Measure the transformer primary inoperative for a

 

 

nominal 120 VAC input. Measure the secondary

 

 

voltage output which will be 12.5 to 15 VAC

 

 

normally. Recheck secondary output at rear of

 

 

Time/Temp Display. Terminals 1 to 3 should read

 

 

12.5 to 15 VAC. Terminals 1 to 2 and 2 to 3 should

 

 

be exactly 1/2 of the reading across 1 to 3. If you

 

 

do not get the above secondary readings, replace

 

 

the transformer. If 120 VAC primary voltage is not

 

 

available, refer to the schematic and trace circuit

 

 

for incoming power failure. There is a 4 amp fuse in

 

 

each red secondary lead. These may be jumpered

 

 

(for test only) to determine if they are defective or

 

 

intermittent.

NOTE:

(Dual Belt Ovens)

Dual belt ovens utilize a double pole double throw

 

 

switch, which allows either of the optical encoders

 

 

to be read from a single Time/Temp. Display.

 

 

Check switch and replace as needed.
