Operating Modes

Fail Safe Operation

Assume the lock is installed, wired, and set to fail safe. The door is open and the positive supply voltage is applied to the BLUE wire. As the door closes the SL30SGL senses the door approaching and activates the bolt pin to pull the door into alignment. The Bolt Position and Door Position monitors will have changed to closed contact state as the door is closed and secured.

To unlock the door, the voltage is removed from the BLUE wire. The SL30SGL will immediately release and will do so even when significant load is being applied to the door. With the door now open the Bolt Position and Door Position monitors change to open contact state. The SL30SGL will remain unlocked as long as the door is open but will instantly re-lock when voltage is applied to the BLUE wire and the door is closed.

In the event of a power failure, the SL30SGL unlocks.

Fail Secure Operation

Assume the lock is installed, wired, and set to fail secure. The door is open and the positive supply voltage is removed from the BLUE wire. As the door closes the SL30SGL senses the door approaching and activates the bolt pin to pull the door into alignment. The Bolt Position and Door Position monitors will have changed to closed contact state as the door is closed and secured.

To unlock the door, the voltage is applied to the BLUE wire. The SL30SGL will immediately release and will do so even when significant load is being applied to the door. With the door now open the Bolt Position and Door Position monitors change to open contact state. The SL30SGL will remain unlocked as long as the door is open but will instantly re-lock when voltage is removed from the BLUE wire and the door is closed.

In the event of a power failure, the SL30SGL will lock, or remain locked, if the door is closed.
