4. DESIGN AND PRINCIPLE OF OPERATION
The lock Promix-SM308 is produced in a normally closed version, i.e., it is in the closed state
when de-energized and opens as supply voltage is applied.
The lock is mounted on inner surfaces of the locker transversely to the door and is operable in
both vertical and horizontal positions. The mating part (latch) is mounted on the door.
As the door is closed, the latch is inserted in the lock and becomes blocked therein. As supply
voltage is applied, the lock deblocks the latch and pushes it with a built-in pusher, which allows to
eliminate mounting of a handle on the door.
The spring-loaded pusher of the lock is connected to the door position sensor. The operating
principle of the sensor is described in 6.3.
