Door Lock Assembly
The door lock assembly consists of a lock motor
cam and switch assembly, lock hook, and mounting
plate.
The lock motor is energized when the control is set
for CLEAN and CLEAN TIME is selected.
The K13
relay
contacts will close and complete the circuit
that supplies the voltage to the lock motor.
Note:
Display of control will
fl
ash “LOCK DOOR” if the
door switch is in the “C” to “NC” position (door open).
• The word “LOCKED DOOR” will
fl
ash 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:
Positions the lock hook in the door to prevent
1.
opening during clean operation.
Operates the lock switches which tell the control
2.
if the door is unlocked or locked and ready for
clean operation.
Note:
When the door is either being locked or
unlocked, both lock switches will be in the open
position.
The door lock motor has an approximate resistance
value of 1.97K
