After power on and expiry of the power-on delay time of approx� 5 s the unit is in
the RUN mode (= normal operating mode)� It carries out its measurement and
evaluation functions and generates output signals according to the set parame-
ters�
• During the power-on delay time the outputs are switched as programmed:
-ON with normally open function (Hno / Fno)
-OFF with normally closed function (Hnc / Fnc)�
-ON for detection of direction (dir�F)
• If output 2 is configured as analogue output, the output signal is at 20 mA
(current output) or 10 V (voltage output)�
10 Parameter setting
Parameters can be set before installation or during operation�
If you change parameters during operation, this will influence the function�
