Quick Starter – Rain Sensor Settings

DIP Switches setup for mode 1 rain detector

Eager to test out your rain sensor now? This is a quick starter guide to help you familiar with your sensor.

  1. Open up the rain sensor’s dome with the 4 screws found at the bottom of the enclosure. Connect the power to P1 P2 (12V or 24V).
    .
  2. You can set to the DIP switches (to rain sensing mode) as illustrated on the right (DIP switch 1 = ON, switch 5 = ON).
    .
  3. Assembly back the rain sensor‘s enclosure.
    .
  4. Spray or dip some water on top of the rain sensor clear dome cover. You should see a tiny green light glow in the centre of the circuit board. This green light indicates that relay output is triggered by the water.
    .
  5. To test the sensor if it can detect a rain stop, just hold and wait for 2-3 minutes. You do not need to wipe off the water droplet on top of the sensor’s dome cover. You should see the green indicator light turn off after a period of about 2-3 minutes. This means that sensor has detected that the rain is stopped.
