Operating instructions
3.3 Safety equipment
3.3.1 Main closing edge safety sensors
The area of movement between the open door leaves is monitored by safety
sensors. If a person or object enters the detection area of the safety sensors during
the closing movement, the door brakes, opens and remains in the open position.
When the monitored area is clear again, the door closes after the hold-open time
expires. The safety sensors are tested automatically before every closing
movement. If the test is negative, the control unit reports the corresponding error
and the door no longer closes. The unit must be inspected by a service technician.
3.3.2 Secondary closing edge safety sensors (optional)
The secondary closing edges are monitored by safety sensors. If a person or object
enters the detection area of the safety sensors during the opening movement, the
door stops. Depending on the door unit setting, the door remains still or continues
to move slowly.
3.3.3 Force monitoring
The control unit detects obstacles that are not detected by the safety sensors (e.g.
a doormat lying in the area of movement).
3.3.3.1 Force monitoring during the closing movement
If the obstacle is detected during a closing movement, the door opens again. When
the hold-open time expires, the door closes. Depending on the setting, the next
closure is done slowly. This process is repeated until the obstacle is removed.
3.3.3.2 Force monitoring during the opening movement
If the obstacle is detected during an opening movement, the door stops. The door
performs up to 6opening movements at creep speed. If the obstacle is still present,
the door closes. At the next opening impulse, the door opens at creep speed. This
process is repeated until the obstacle is removed.
3.4 Automatic adjustment of the hold-open time to the footfall
To protect the drive from overheating, the hold-open time is automatically
extended when the door unit experiences high footfall. The hold-open time is
automatically reduced to the set value when the footfall drops again.
