6.4. Setting using the W programming wire
With the variants provided with the remote parametrization option (RFLS-28_-_-_-PD_MW), it is
possible to set the sensor using the
W
programming wire, or a special evaluation unit SSU-1212-
AD, respectively. This unit is equipped with a contact (terminal No. 7) to connect the programming
wire allowing the
basic settings
of the sensor to be performed. Quick settings as per paragraph
6.1.1 or the setting of the “Medium window” mode as per paragraph 6.1.3 is not possible.
6.4.1. Evaluation units SSU-1212-AD
The unit has one input for the connection of the operating sensor (marked as IN, terminal No. 3).
The operating sensor enables the control of the operating relay (terminals 14, 15, 16). The unit is
fitted with the diagnostic function monitoring the correct operation of the connected sensor, and
the remote parametrization function for the connected sensor using the W programming wire. The
programming wire is connected to the terminal marked as P (terminal No. 7).

Description of setting elements
by the “
P / N
” switch
• P position
– the unit reacts to the current entering the input terminal (No. 3) for the PNP-type
sensors
N position
– the unit reacts to current leaving the input terminal (No. 3)
for the NPN-type, “S”, and Namur sensors, or those with voltage-free contact output
by the “
SET CH OFF / ON
” switch
• OFF position
– the setting function of the sensor connected to the IN terminal (No. 3)
deactivated
• ON position
– the setting function of the sensor connected to the IN terminal (No. 3) activated
