Settings on the Unit
The UP watchdog has been set in the Factory to „ Test"
and "Cutout Delay 10 sec.".
During manual adjustment the setscrew scales shall
ser ve for orient ation only. The exact switching
brightness level and cutout delay time must be
determined empirically.
• First, check the switching function of the UP watch-
dog by turning the setscrew to "Test".
– This deactivates the dusk sensor (switching
occurs at any brightness level).
– The cut-in time is approx. 10 seconds.
• Determine the cutout delay by way of experiment.
Position the setscrew onto the sun symbol (switching
occurs at any brightness level). Adjust the cutout
delay via the right setscrew on the back of the unit
and find out the setting that suits your needs best.
• Determine the switching brightness level for the
integrated dusk sensor (find best setting): Turn the
setscrew to a position somewhere between
"switching only when dark" and "switching
irrespective of brightness level" that suits your
requirements.
