Adjustments
The door switch should be adjusted so the cylinder stops when door is opened 2 inches (51 mm) plus or minus 0.25 inch (6 mm). This switch is a normally open switch and is closed by the hinge cam when the door is closed. If adjustment is required, refer to Figure 16 and proceed as follows:
1.Close door and start tumbler, slowly open loading door. Cylinder and heat system should shut off when door is open 2 inches (51 mm) plus or minus 0.25 inch (6 mm).
2.Slowly close the loading door. When door is
2 inches (51 mm) from being fully closed, the door switch actuating bracket (located on the door) should depress the button and the switch arm with an audible “click.”
3.If the actuating bracket does not operate the switch at the appropriate door closure, bend the actuating switch arm in or out to achieve proper actuation.
CE Models Through Serial No. 0208002174CE tumblers have a second door switch near the top of the door (refer to Figure 16). This switch also should be adjusted so cylinder stops when door is opened within 0 – 2 inches (0 – 51 mm). This switch is normally closed and is opened by the hinge cam when the door is opened. If adjustment is needed, refer to Figure 16 and proceed as follows:
1.Remove lower switch actuator (Figure 16) so upper switch “click” can be heard.
2.Loosen upper door switch screws just enough so switch can be moved left and right. Move switch right if door opens too far before switch clicks.
Move switch left if door doesn’t open far enough before switch clicks.
3.Retighten door switch screws and retest. Repeat step 2 if further adjustment is needed.
4.Reinstall lower switch actuator and retest its switch.
