INSTALLATION INSTRUCTIONS & TROUBLESHOOTING

CONNECTING POWER
1. Slide off the terminal cover.
2. Connect power either by:
a) plugging in a 12/24VDC power adapter
OR
b) hardwire directly from a 12/24VDC LED driver to the screw terminals marked “INPUT”.
3. Connect the LED strip using the screw terminals marked “OUTPUT” (5A maximum load).

CONNECTING THE SENSORS 
Plug the PIR sensor into the LHS socket and the LUX sensor into the RHS socket.

DIMMING
Slide off the terminal cover and adjust the dial to suit the required light level.

TIMER SETTINGS
The two DIP switches set the time delay to turn off the light when there is no further triggering. Time settings are 15s, 30s, 1m, 2m.
If re-triggered prior to timing out the timer restarts from zero.
To set, slide off the connection cover and set the DIP switches as follows.

TROUBLE SHOOTING

  • Is the polarity correct for input and output power?
  • Connect the LED light directly to the power supply and check if working and the correct polarity.
  • To test the controller, disconnect all sensors and place a jumper on each input between the left pin and the centre pin of both inputs. The light should now be on. Remove the jumper on the PIR input and the light will turn off when the timer times out.
  • Connect the PIR sensor leaving the the jumper on the LUX sensor input between the left pin and the centre pin.
  • Contact Lightdream Technical Support by phone or email for additional assistance.
