Status signalling
The
SS 20.200
has two light emitting diodes (LED) of different colours,
indicating its current status (depending on the switching behaviour or-
dered).
The following table shows the signalling options and their cause.

Startup
Before switching on it must be checked if the
SS 20.200
is installed cor-
rectly, both mechanically and electrically.
The sensor is ready within 20 s, after applying the operating voltage.
During this initialisation stage, the green LED is flashing.
As soon as the green LED is lit permanently, the sensor is ready.
If the sensor detects an internal defect, the green LED will go off and the
red LED is flashing.
In case of defects the sensor must be sent in to
SCHMIDT
for repair.
