Motorized Door Lock

The motorized door lock assembly (located above
the oven) consists of a lock motor cam and switch
assembly, lock hook, heat barrier, and mounting
plate. The door latch is accessible by removing the
top enclosure.
Motorized Door Lock Operation
The lock motor is energized when the control is
set for CLEAN and CLEAN TIME selected. The
K1 relay contact will close and complete the
circuit that supplies the voltage to the lock motor.
Note: Display will flash LOCK DOOR if the door
switch is in the C to NC position (door open).
The word LOCKED DOOR will flash on and off in
the display while the lock motor is in motion.
When the door is locked the word LOCKED
DOOR remains illuminated in the display.
CAM – The cam on the motor performs two
functions:
1. Positions the lock hook in the door to prevent
opening during clean operation.
2. Operates the lock switches which tell the
control if the door is unlocked or locked and
ready for clean operation.
Note: When door is either being locked or
unlocked both lock switches will be in the open
position.
