INTERLOCK MECHANISM AND ADJUSTMENT
The door lock mechanism is a device which has been specially designed to completely eliminate microwave radiation when
the door is opened during operation, and thus to perfectly prevent the danger resulting from the leakage of microwave.
(1) Primary interlock switch
When the door is closed, the hook locks the oven door. If the door is not closed properly, the oven will not operate.
When the door is closed, the hook pushes the button of the microswitch. Then the button of the primary interlock switch
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
monitor switch to bring it under “OFF” condition and presses the button of the secondary interlock switch to bring it under
“ON” condition.
(3) Adjustment steps
a) Loosen the mounting screw.
b) Adjust interlock switch assembly position.
Actuation distance of primary and secondary interlock switch can be adjusted up tp 0.7mm.
c) Make sure that lock lever moves smoothly after adjustment is completed.
d) Completely tighten all mounting screws.
DOOR CLOSED DOOR OPEN
ADJUSTMENT :
Interlock monitor switch
When the door is closed, the interlock monitor switch should be “OFF” condition before other switches are closed.
When the door is opened, the interlock monitor switch should be “ON” condition after other switches are opened.
NOTE :
1) Service personnel have to reconnect and check continuity of Monitor Circuit.
2) Service personnel have to replace all monitored safety interlocks after monitored interlock failure.
3) Microwave emission test should be performed after adjusting interlock mechanism or replacing of all monitored safety
interlocks after monitored interlock failure.
If the microwave emission exceed 4mW/cm², readjust interlock mechanism.
