1. Operating Mode
1.1 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 SL30DBL 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 SL30DBL 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 SL30DBL 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 SL30DBL unlocks.
1.2 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 SL30DBL 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 SL30DBL 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 SL30DBL 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 SL30DBL will lock, or remain locked, if the door is closed.
