original settings, the running distance has to be relearned.
9. Safety contact profiles for gate open (SLA) and close (SLZ)
Gates with two wings: When a safety contact profile is activated, both motors react.
The controller has two integrated detectors with testing function (according to EN954-1
category 2 for safety contact profiles with 8.2kOhm resistor) for gate OPEN and CLOSE.
The status of the safety contact profiles is displayed by red LEDs (SLA and SLZ). When
the safety contact profile is activated, the matching LED lights.

The connection of the n.o. contact with 8.2k
Ω
±5% resistor (parallel) or the n.c. contact
with 8.2k
Ω
±5% resistor (serial) is possible. In case no safety contact profiles are
connected, an 8.2k
Ω
±5% resistor has to be connected.
When using more than one safety contact profile, they can be connected in sequence (see
drawing below).
