Operating Cycle Examples for Standard Models
D4SL-N@@@A-@ (Mechanical Lock Models)
D4SL-N@@@G-@ (Solenoid Lock Models)
Door open/closed detection and lock monitor contacts: Can be used in safety circuits because of the direct opening mechanisms.
Door open/closed detection contact: Can be used to confirm whether the key is inserted and to monitor the open/closed status of a door.
Lock monitor contact: Can be used to confirm whether power is supplied to the solenoid and to monitor whether or not a door can be opened or closed.
Note: 1. The door open/closed detection and lock monitor contact configuration depends on the model.
2. If a current is detected in the solenoid lock model (built-in switches; N, P, Q, R), before the door is closed, the door will remain unlocked.
Be sure to supply power to the solenoid after the door is closed.
