6.1 Signal Indicators
LED Power (green)
Suppl�� voltage
LED Transmit Opening (red)
Fault, opening movement ‑ travelling edge(s)
LED Stationary Opening (red)
Fault, opening movement stationar�� edge(s)
LED Transmit Closing (red)
Fault, closing movement ‑ travelling edge(s)
LED Stationary Closing (red)
Fault, closing movement ‑ stationar�� edge(s)
I� no error is present, then LED Power shows the �unction control (briefl�� off). During the output o� an error
message, the number o� output pulses indicates the error:
