Speed Control Potentiometer

This is a 0 to 400 ohm or 0 to 500 ohm, 10-turn

 

 

potentiometer. WITH POWER OFF: remove the

 

 

red, white, and black leads from terminals S1, S2,

 

 

S3. With a digital multimeter, check the ohm

 

 

reading across the red to black leads. This ohm

 

 

reading should be a steady 400-ohm, or 500-ohm,

 

 

through the entire 10-turn rotation of the

 

 

potentiometer. Check for shorts or opens or

 

 

unsteady, ohm reading, if potentiometer is

 

 

defective, replace. If the potentiometer checks OK,

 

 

and there is no output at terminals A1 and A2,

 

 

replace the D. C. control board.

 

 

Reversing Switch

If there is D. C. voltage output from the motor

 

 

control board, but the conveyor drive motor is not

 

 

running, check the D.P.D.T. reversing switch.

 

Conveyor Drive Motor

Check the conveyor drive sprocket for tightness.

 

 

Disconnect the motor, check the red and black

 

 

motor leads for opens, shorts or grounds. Check

 

 

the brushes for excessive or

abnormal wear.

 

 

Replace as needed. Reconnect motor. Test for

 

 

operation. If motor does not run, replace.

(Dual Belt Ovens)

Dual belt ovens utilize 2 complete independent

 

 

conveyor drive systems. The trouble shooting

 

 

procedures are the same as single belt ovens,

 

 

except that the dual belt ovens use one each of the

 

 

following: one "A" D. C. control board and one "B"

power off, remove the red, black and white pot

 

 

leads from the motor control board at terminals P1,

 

 

P2 and P3. With a digital multimeter, check the

 

 

ohm reading across the red lead (P3) to the black

 

 

lead (P1). This reading should be 5 K ohms ± 5%

 

 

as the pot is rotated from low to high. Place the

 

 

meter leads on the red lead (P3) and on the white

 

 

lead (P2) Rotating the pot. slowly, from low to high,

DC Motor Control Board

Check for 120 VAC input to the control board at

 

 

terminals L1 and L2. If not present, check the

 

 

conveyor switch and wiring back to 3-amp fuse and

 

 

then back to power source if necessary. If 120 VAC

 

 

is present at L1 and L2, check the VDC output at

 

 

terminals A+ and A-. If a DC voltage is not present,

 

 

check the 4 amp and the 1 amp fuses on the

 

 

control board. Also reset and check the mini

 

 

breaker in the armature line to the gearmotor. If

 

 

120 VAC is present at terminals L1 and L2, but DC

 

 

voltage is not present at A+ and A-, providing the 1

 

 

amp and 4 amp fuses are good, replace the board.

 

 

If DC voltage is present at A+ and A-, but motor

 

 

does not run, check gear motor as follows.
