Testing the System
After installation; test the sensor to ensure it is
working correctly. Turn the controller on to initiate
irrigation. Hold down the plunger located on top of
the rain sensor as shown in Figure 4 (B). The zone
should turn off after a few seconds. If it does not turn
off, check your rain sensor wire connections.
Maintenance
The RSD Rain Sensor operates automatically and
requires no scheduled maintenance. However, the
disks inside the sensor dial cap sometimes become
contaminated with debris or insects. If this happens,
use the following procedure to clean the Rain
Sensor.
1.
Turn the dial cap to the 3/4" rainfall setting, as
shown in Figure 2.
2.
Press the tab labeled "Press" on the side of the
sensor body, as shown in Figure 8 (A). Then
turn the dial cap about 1 1/4 turns further to
remove the cap from the sensor body.
3.
Remove the plunger and disks from the sensor
body and wash them in clean water.
4.
Reinstall the plunger and disks. Then reset the
rainfall setting to the desired position, as shown
in Figure 2.
