Time display inaccurate

erratic, or inoperative

Perform all checks as in the above evaluation. If

the time check is okay, refer to the next section

optical encoder.

Optical Encoder

The above time/temp test should have already

been performed. Remove dust cover from the

gearmotor and inspect the coupling and encoder

disc. The coupling set screws should be tight and

not slipping on the motor shaft or the tach.

generator shaft. The encoder disc should be firmly

attached to the coupling and not warped. Check the

positioning of the optical encoder disc. The disc

should not be touching the optical encoder

assembly and the encoder assembly should be

mounted so it is squarely facing the coupling shaft.

This is to allow the infrared beams to be broken by

the encoder disc. If all this is okay, then replace the

optical encoder assembly.

Conveyor Drive (Stepper)

Control

Perform all checks as in the above evaluation. If

the time check is okay, refer to the next section.

Check to see if the conveyor drive (stepper) motor

is running. If motor is not running, refer to

"Conveyor will not run" on page 43.

Magnet

Check to insure that the magnet (cemented to shaft

of conveyor drive (stepper) motor) has not been

damaged, or come loose from motor shaft. Replace

as needed.

Hall Effect Sensor

Check for any physical damage to Hall Effect

sensor (mounted on conveyor drive(stepper)

motor). Check all wiring and connections for

damage.

Time Display

inaccurate, erratic, or

inoperative(S/N

Q19078 & Above1000

Series) (S/N Q14791 &

Above1200 Series)

Conveyor Drive (Stepper)

Control

Check all connections for tightness or proper

location and check all wiring for visible damage.

Replace as needed. If there is still no time display,

wire in (temporarily) a new conveyor drive control.

If there is still no time display, reconnect original

conveyor drive control. Replace Hall Effect Sensor.
