bring it under ON condition.
(2) Secondary interlock switch and interlock monitor switch
When the door is closed, the hook pushes the lock lever downward. The lock lever presses the button of the interlock
minitor switch to bring it under NO condition and presses the button of the secondary interlock switch to bring it under
ON condition.
(3) Adjustment steps
a) Loosen the one mounting screw.
b) Adjust interlock switch assmbly position.
c) Make sure that lock lever moves smoothly after adjustment is completed.
d) Tighten completely one mounting screw.

When the door is closed, the interlock monitor switch should be changed(NO condition) before other switches
are closed.
When the door is opened, the interlock monitor switch should be changed(NC condition) after other switches are
opened.
NOTE :
Microwave emission test should be performed after adjusting interlock mechanism. If the microwave
emission exceed 4 mW/cm

, readjust interlock mechanism.
