Functions on the extension unit EXU-SA

Also see page 59 for more information.
5.6.1

Presence impulse approach, door mounted

The presence impulse is active during fully open and closing. The sensor is mounted to the approach
side of the door. Once the door is closed, the sensor is ignored and will not be active until the next
impulse is received.
Note! When installed as a pair of doors, the presence impulse signal will re-open both doors. The
sensor is not active in program mode OFF, manually opened door or during battery operation
(Power Failure Mode).
5.6.2

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 72.
5.6.3

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.
5.6.4

Relay output

A potential free contact COM/NO/NC used in the below four different way, where the first three
are chosen by Parameter group (see 'Relay' in table at page 72).
• Error indication
For external error indication, see page 83.
• KILL output
Used for distribute KILL-signal to other door sets.
• Lock output
Used for control locks with other voltage than 12/24 VDC.
• Door indication (HW-wired with jumper)
Used for indicate an open or closed position of the door. The indication position is set by adjust-
ing the inhibit/blanking potentiometer. For indication of closed door, adjust the Blanking po-
tentiometer to minimum. For indication of open door, open the door by program select OPEN
or any open-impulse, and adjust the Blanking potentiometer so that the Blanking LED is lit only
in open position (or above desired position, just like blanking).
