5.If it is necessary to add or remove conveyor links to achieve the correct tension, OR if it is necessary to reverse the conveyor belt for correct orientation, the belt will need to be removed from the conveyor frame. If this is necessary, perform the following procedure:

•Remove the conveyor assembly from the oven and place it flat on the floor.

•Remove the master links using long-nose pliers. Then, roll up the belt along the length of the conveyor frame.

•Add or remove belt links as necessary to achieve the correct belt tension.

•Replace the belt on the conveyor frame. Check that the conveyor belt links are oriented as shown in Figure 2-15, and that the smooth side of the conveyor belt faces UP.

•Connect the inside master links. Check that the links are oriented as shown in Figure 2-15.

•Connect the outside master links. Note that the outside master links each have an open hook on one side. This hook aligns with the hooks along the sides of the other conveyor links. See Figure 2-15.

•Replace the conveyor into the oven.

CONVEYOR BELT REVERSAL

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.

CAUTION: Shock hazard in compartments electrical filters are electrically alive.

SWITCHING PHOTO DETECTOR

CAUTION: Disconnect Power Before Switching Photo eye.

Remove the three screws securing the access door to the unit. Open the access door and disconnect the connector fitting to the photo eye assembly. Remove the two screws securing the photo eye assembly to the control box. Remove the four nuts securing the photo eye to the housing. Rotate the photo eye 180 degrees and resecure the photo eye with the four nuts.

On the opposite control box, remove the two screws holding the cover where the photo eye assembly will be positioned. Secure the photo eye assembly in position with the two screws. Place the photo eye cover on the opposite control box, where the photo eye assembly was removed, and secure the two screws. Secure the access door with the three screws.

Remove the three screws securing the access door on the opposite side. Open the access door, where the photo eye is now positioned, and connect the photo eye connector fitting. Secure the access door with the three screws.

Apply power to the unit. Adjust the photo eye height by loosen- ing the two screws securing the photo eye assembly and sliding the photo eye assembly either up or down, such that the beam is approximately 1/4 inch above the belt.

Note: This is MUCH easier in reduced light.

Replace all covers.
