dark switching light switching
2 1 t = 1
1 2 t = 2
Timer stages can be set from 0 to 2 seconds.
Light/dark switch: The sensor is in light switching mode when optional light/dark poten‐
tiometer is rotated to the “L” position. The sensor is in dark switching mode when
optional light/dark potentiometer is rotated to the “D” position. The green power supply
LED will flash once when the mode is changed.
6 Fault diagnosis
Table indicates which measures are to be taken if the sensor stops working.
