Connection of safety sensors
These sensors are installed on both sides of the door leaves in the swing door system and
monitor the swing range of the door. When an obstacle is detected upon opening, the door
will stop and when closing, a re-opening is triggered.
The door control of the DFA 127 enables the sensor to monitor any dangerous movement (in
compliance with EN 13849-1).
SIO Safety signal in opening direction.
0 V / open = active safety
24 V = passive safety
⇒ A closed door only opens when the signal is passive.
⇒ If the signal is active during an opening movement, the door will stop.
⇒ If the door is opening against a wall, the SIO signal disappears from a certain door
position.
SIS Safety signal in closing direction.
0 V / open = active safety
24 V = passive safety
⇒ An open door only closes when the signal is passive.
⇒ If the signal is active during a closing movement, the door will reverse direction.
Wiring
Connect SIO and SIS according to the following scheme.
IMPORTANT
Only products in compliance with EN 13849-1:2008 category 2 PL c are permit-
ted.
