Setting
Standard setting (to max. sensitivity)
1. Position the sensor and reflector at 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 switch-
point.
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 small objects
1. Perform the standard setting.
2. Turn the potentiometer counterclockwise 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.
Excess gain
The excess gain is a unitless factor which indicates how
much more light reaches the receiver than is necessary for
function of the sensor. The larger the factor, the more
stable the sensor operates. For applications in dirty sur-
roundings a greater excess gain is needed than under
laboratory conditions. The maximum range of the sensor
should therefore not always be used.
