Fig. 5: Indicators and operating elements
Yellow LED: Output function
(not for BOS 21M-XI-RS31-S4)
LED on: Light received and over switching threshold
LED off: No light received
LED flashing: Limit area, Excess gain < 1.5
Green LED: Operating display
LED on: Power present
LED off: Sensor not ready
LED flashing: IO-Link communication (1:10), error (1:1)
Potentiometer
(not for BOS 21M-XI-RS31-S4)
Setting: Switching distance
Setting
Standard setting (to max. sensitivity)
1. Position the sensor and reflector to the desired
distance.
2. Set potentiometer to max. sensitivity (full clockwise).
3. Determine the on and off point of the output (yellow
LED): move the sensor in several directions so that the
yellow LED switches on and then back off. Each
switching state change indicates one switchpoint.
4. Mount the sensor in the middle of the determined
switchpoints. The sensor is optimally aligned when the
yellow LED is continuously on to indicate reliable
function.
Fine adjustment to detect very small objects
1. First perform the standard setting (see above).
2. Turn the potentiometer counter-clockwise until the
yellow LED goes out. The reflector is no longer
recognized.
3. Slowly turn the potentiometer clockwise until the yellow
LED turns on. The reflector is recognized again. Now
very small objects can also be detected.
