LOADING DOOR SWITCH

The door switch should be adjusted so the cylinder stops when door is opened two inches (5.08 cm), plus or minus 1/4 inch (.63 cm). This switch is a normally open switch and is closed by the interlock rod when the door is closed. If adjustment is required, proceed as follows. Refer to Figure 18.

1.Close door and start tumbler, slowly open loading door. Cylinder and heat system should shut off when door is open two inches (5.08 cm) plus or minus 1/4 inch (.63 cm).

2.Slowly close loading door. When door is two inches from being fully closed, the tab should contact the interlock rod and depress it enough to operate the switch arm closing the switch with an audible “click”.

3.If interlock rod does not depress enough to operate the switch, bend tab on loading door OUTWARD one eighth inch (.32 cm) and repeat steps “1” and “2”. Bend tab outward an additional 1/8, inch (.32 cm) if required to obtain proper rod movement and switch operation.

4.If proper operation is not obtained by procedure outlined in step “3”, unlock and open top panel and remove control panel. Loosen the two adjusting screws holding the switch to the bracket and move switch 1/8, inch (.32 cm) toward the front of the switch bracket and retighten the screws. Repeat steps “1” and “2”. If switch and rod still do not have sufficient movement, move switch forward an additional 1/8 inch (.32 cm).
