Lincoln Series 1000 Manuel D’Utilisation

Impinger I -–1000 Series Service Manual - International

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)

Transformer

Check for 120 VAC supply to primary of

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

Potentiometer

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

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)

Control

NOTE: if the conveyor drive motor becomes

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 will not

run(S/N Q19078 &

Up1000 Series) (S/N

Q14791 & Up1200

Series)

Conveyor Drive (Stepper)

Motor

Check the drive sprocket on motor out-put shaft to

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.
