Health
Health output: The sensor (WLA16 Bluetooth) features a pre-failure notification output
(“Health” in connection diagram table 4), which issues a notification if the sensor is
only ready for operation to a limited extent or the cable has been interrupted. Possible
causes: Sensor or reflector is contaminated, sensor is out of alignment, cable is dam‐
aged. In the good state: HIGH (1), if excessively contaminated or in the event of cable
interruption LOW (0). The yellow LED indicator flashes in this case.

6 Commissioning
Bluetooth® is switched on for initial commissioning. You can get SOPASair in the Google
PlayStore (Android) and in the App Store (iOS).
Operating system requirements: Android version 6.0, most current version of iOS.
1Alignment
Align the sensor with a suitable reflector. Select the position so that the red emitted light
beam hits the center of the reflector. The sensor must have a clear view of the reflector,
with no object in the path of the beam [see figure 3]. You must ensure that the optical
openings of the sensor and reflector are completely clear.

2Sensing range
Adjust the distance between the sensor and the reflector according to the corresponding
diagram [see figure 5] (x = sensing range, y = operating reserve).
