Door Closer Position Switch Circuit
CIRCUIT DESCRIPTIONThe closer position switch is built in the door lock assembly and detects the position of the closer.
The condition of the HALF/FULL/POLE switches and the door for each case is as follows.
1. CONDITIONS FOR STARTING DOOR CLOSER OPERATION
- Door closer detection switch: original position
- Full latch switch ON
- Half latch switch ON
After detecting the conditions mentioned above, if the following conditions continue for 300 msec., the door closer motor starts rotating in the regular direction.
- Door closer detection switch: original position
- Full latch switch ON
- Half latch switch OFF
- Pole switch: ON
2. CONDITIONS FOR CANCELING DOOR CLOSER OPERATION
If the following conditions are detected during the door closer motor's regular rotation, the door closer operation is stopped. After 100 msec., the door closer motor starts rotating in the reverse direction to move to the original position
- Door closer detection switch: reverse rotation range
- Half latch switch ON
- The motor receives voltage for 3 seconds or more.
- Door unlock detection switch: LOCK
3. CONDITIONS FOR FINISHING DOOR CLOSER OPERATION
If the following conditions are detected during the door closer motor's regular rotation, the door closer operation is stopped. After 100 msec., it makes reverse rotation to move the door closer 150 ± 20 msec.
- Full latch switch OFF
- Half latch switch OFF
- Pole switch: OFF
4. CONDITIONS FOR CANCELING DOOR CLOSER REVERSE ROTATION
If the following conditions are detected during the door closer motor's reverse rotation, the door closer is moved to the original position
- Full latch switch ON
- Half latch switch ON
