Conveyor will not run(S/N Q19078 & Up1000 Series) (S/N Q14791 & Up1200 Series)

Voltage Supply

Check incoming voltage supply at Line 1 to neutral.

 

There should be a voltage reading of 120 VAC.

Fan Switch

See procedure for checking on page 26.

Conveyor Switch

Check for 120 VAC to conveyor switch. If no

 

voltage is present, trace wiring back to the fan

 

switch. WITH POWER OFF: Check continuity

 

between switch terminals.

Conveyor Fuse (3A)

Check, replace if necessary.

Fuseholder

Check, replace if necessary.

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.
