TACH. GENERATOR

1.Shut off power at main breaker.

2.Remove conveyor motor assembly .

3.Remove tach. cover plate and tach. Ieads. Mark lead position.

4.Remove 2 slotted screws from dust cover base and remove dust cover.

5.Loosen coupling set screw (.050 inch allen wrench).

6.Remove tach. bracket from motor.

7.Remove 4 screws from base of tach. and tach. is now free for removal.

8.Reassemble in reverse order. Maintain spacing of .010 minimum between tach. Bracket and coupler hub.

NOTE: If a new tach. generator is installed, the D.C. motor control board MUST BE RECALIBRATED There is no repair procedure for the tach. If defective, replace.

CONVEYOR MOTOR CONTROL BOARD

1.Shut off power at main breaker.

2.Remove control panel top and front cover.

3.Remove cover from relay box. SN 100-4389 BODINE SYSTEM

Remove wires from terminal strip on control board making sure to mark wires so they will be reinserted on the proper terminal.

Remove the four (4) hex head screws.

Reassemble in reverse order and calibrate (See D. C. Motor Control Board - Calibration, Bodine System)

SN 4390-14974 1000 SERIES GAS OVENS SN 4390-14791 1200 SERIES GAS OVENS

4.Make note of wire number and location before removing them from the control board. POLARITY BETWEEN, T1-T2 AND A+ AND A- IS CRITICAL. The bottom mounting screw need only be loosened as the mounting bracket for the control board is slotted. Remove top two (2)mounting screws and remove control board.

NOTE: Exchange boards on the mounting bracket before reinstallation.

5.Reassemble in reverse order and calibrate (See D. C. Motor Control Board - Calibration)

SN 14975 AND ABOVE 1000 SERIES GAS OVENS SN 14792 AND ABOVE 1200 SERIES GAS OVENS

Make note of wire numbers and location before removing them from the control board.

6.The bottom mounting screw need only be loosened as the mounting bracket for the control board is slotted. Remove top two (2) mounting screws and remove control board.

7.Reassemble in reverse order and calibrate. (See Stepper Control-Adjustment)

D. C. MOTOR CONTROL BOARD - CALIBRATION

SN 100 to 4389 - BODINE SYSTEM

1.Remove control panel top and front cover.

2.Remove cover from relay box.

3.Identify D. C. control board and calibrate as per the following instructions:

NOTE: THE USE OF A DIGITAL VOLTMETER IS NECESSARY FOR PROPER ADJUSTMENT Check incoming AC voltage at L1 and L2. Should be 120 VAC ± 10%.

Check field voltage at terminals F1 and F2. Should be 100 VDC ± 10 volts. Turn speed control dial clockwise to its maximum speed position.

PLACE DIGITAL VOLTMETER LEADS ON terminal S1 and S2, adjust the max pot. for a reading of 3.4 VDC.

Place METER LEADS on terminals A1 and A2. Adjust the reg. pot. for a reading of 125 VDC. NOTE: In some instances when the input AC voltage runs on the high side of the normal input range, you may have difficulty adjusting the max. pot. for a reading of 3.4 VDC. In this instance, a reading of 3.45 VDC is acceptable.

Adjust speed pot to obtain the proper time setting for the conveyor to meet customers desired speed .

Check conveyor travel in a no load situation to insure conveyor belt is traveling at a constant speed.
