Lincoln Impinger Conveyor Oven Model #1132 Serial #2010604 The time adjustment for the conveyor is not responding. I had it set at 2 minutes and 30 seconds, but it is running at 65 seconds. I cannot adjust the time. sy

Closing the Conveyor Switch supplies 120 VAC to the DC Motor Control Board at
terminals L1 and L2. A.C.volts are converted to DC volts and are supplied to the
Conveyor Motor at terminals A+ and A-. Adjustment of the Speed Control
Potentiometer (5,000 ohm, 10 turn) will change resistance at terminals P1, P2,
and P3varying the DC voltage to the Conveyor Motor. The speed of the conveyor
motor will increase or decrease as the DC voltage from the board increases or
decreases respectively. As the motor turns, it drives both the reducer gear box
and the tach. generator. The tach. generator is a DC voltage generator which
supplies a voltage to the DC Motor Control Board which is used as a reference
for maintaining a constant conveyor speed. See page 3
