5.5.2 Presence detection swingpath, door mounted
When a sensor that is mounted on the swing side of a door detects an object, it will send a command
to the control unit to stall the door. If the control unit has received a short signal from the sensor
and there is still hold open time left on the control unit, the door will continue on its way open if
the object has cleared.
The inhibit/blanking potentiometer can be adjusted so that the sensor will avoid detecting a wall
or object near the full open position. Presence detection has a higher priority than presence impulse.
Note! When installed as a pair of doors the presence detection signal will stop both doors, except
for double egress doors. The behavior for double egress doors can be changed (see page 58). The
sensor is not active in program mode OFF, manually opened door or during battery operation.
5.5.3 Monitored safety sensors
Both presence impulse and presence detection can be monitored. If a sensor becomes defective,
the operator will not accept any impulses and will then work as a manual door closer.
5.5.4 Open door indication
A relay output is used to indicate an opening cycle or a specific position of the door. The indication
position is set by adjusting the inhibit/blanking potentiometer.
5.5.5 Error indication
A potential free contact COM/NO/NC for external error indication, see page 66.
