Conveyor Belt Reversal

Mount the new reflector bracket to the provided holes on the front right-hand side of the oven. The reflector should be po- sitioned just above the conveyor belt.

Using an assistant, hold both back cover switches in the closed position. This will allow power to the photo-eye, and it will pro- vide a red beam for aiming. Loosen one of the screws holding the photo detector gimbal tight, allowing it to be reaimed at the reflector. The beam should hit exactly in the center of the reflector, then tighten the screw back down.

Note: This is MUCH easier in reduced light.

Replace all covers.

ATTACHING THE POINT OF SALE CABLE

Remove the cable (P/N 59198) from the Kit. Attach the 90 degree plug to the rear of the touchscreen display and route the serial connector out the grommetted bottom hole and along the gas pipe. Connect the serial connector with the cable sup-

plied by the customer.

Conveyor belt reversal consists of three steps:

1.Physically reversing the conveyor belt

2.Resetting direction jumper on the conveyor control board.

3.Switching the photo detector.

REVERSING THE CONVEYOR BELT

Remove the conveyor from the oven and find the master link location. Remove master links and remove the belt from the conveyor frame. Reassemble the belt back onto the frame (in the reverse direction) and reinstall the master links. Replace the conveyor assembly in the oven.

RESETTING DIRECTION JUMPER

Locate Jumper P1 on the conveyor control board. Move jumper from terminals 1 and 2, and replace onto terminals 2 and 3.

SWITCHING PHOTO DETECTOR

Remove both rear fan belt covers, then remove the motor cover assembly from both sides of the oven. The photo eye is located on the front side of the left motor bracket. Disconnect the three connecting wires, noting which color wires assemble to the associated wires on the photo-detector. Remove the entire photo detector bracket. Replace the assembly to the right-hand side of the unit, mirroring the way it was assembled on the left. Reconnect the detector wiring in the same order it was on the left.

Incoming electrical power lines are fed through the strain-relief fitting, shown in Figure 2-12. The electrical supply connections are made inside the electrical junction box. The power lines then connect to the oven circuits through safety switches located inside the machinery compartment and each blower motor compartment. These switches interrupt electrical power to the oven when the Machinery Compartment Access Panel is opened, OR when either of the blower or rear shrouds is

removed.
