This setting indicates the position A yellow LED of the sensitivity adjuster. * Remove the object. Increase the sensitivity slowly (turning the sensitivity adjuster clockwise) until the yellow LED lights up again. This setting indicates the position B of the sensitivity adjuster. Note: SENS. In case of no background object, the LED won't light up, even in MAX. adjustment. In that case take care, that in normal operation conditions no temporal background object light/dark switch sensitivity adjuster can appear in the sensing range (e. g. parked pallets). If this can not be excluded, place (only for adjustment matter) an object at the appropriate location. Then repeat this adjustment step. After finishing the adjustment this temporal object should be removed. * For optimal setting, now turn the sensitivity adjuster to the middle position between the positions A and B. 4 Refer to "General Notes Relating to Pepperl+Fuchs Product Information".
