LED (light) ring
The light ring encircling the enclosure serves as an additional signaling,
which depends on whether and if so, which module is connected.

Flow sensor without auxiliary module
In this case, the light ring signals the operating status of the SS 20.700 ,
supplementary to the Duo-LED strip in the cover of the enclosure:

Ring lights green: Sensor is in operation

Ring flashes orange: Operational parameter violated
- Supply voltage
- Temperature of electronics
- Temperature of medium

Ring flashes red: Sensor is defective

Flow sensor with connected auxiliary module
The operating status of the SS 20.700 has signal priority, i.e.
if a problem occurs in the sensor, it will be indicated like written
above.
If the SS 20.700 is fully operational, the light ring indicates the status
of communication between sensor and module according Table 6.

„Rotating“:
Clockwise rotation (view on enclosure cover)
„R/s“:
Revolutions (= completed rotations) per second
„O1“, „O2“; „I1“, „I2“:
LEDs near both connec
tors („O“: outside; „I“: inside, see
Figure 5-2)
„O/I alternating flashing“: LED-pairs „O1 + O2“ and „I1 + I2“ flashing alternately
