The safe functions - force limitation, energy limitation and end position detection - fulfill the requirements according to DIN EN ISO 13849-1:2008 for Category 2 and Performance Level d. The drives are suitable for power-operated guards according to EN 953:1997+A1:2009.

The geared motors are the maintenance-free drive unit of the door drive. The geared motors are DC motors with non-self-locking gearing, and are speed-controlled. The set force and speed limits are not exceeded.

Operation of the door drives listed here does not require a limit switch. The door width and the "OPEN/CLOSED" positions are determined automatically.

Forces are transferred via a toothed belt. The toothed belt passes over a deflector pulley, and can be fitted with 2 clutch holders. This enables it to drive both single-sided and centrally-opening doors.
