OPTICAL RAIN GAGE
MODEL RG-11
INSTALLING THE RAIN SENSOR
Mount the rain gage where it gets a clear measurement
of precipitation– away from overhangs, etc.
The mounting arm is designed to fit over a strap 0.75”
(19 mm) wide. Two 0.25” (holes 6.35 mm) are placed
0.75” (19 mm) part.
The gland style connector goes in the bottom hole. Be
sure to use wire rated for outdoor (high-UV) use.
For conduit applications, the mounting arm may be
removed, and the wiring hole drilled out using a step drill
to accommodate a ½” EMT compression connector or
similar style of conduit connector.
Assemble the device as shown. Stretch and release the
silicone o-ring (size -036) a few times, so it fits easily in
the groove. Optionally, you may coat the O-ring and
screws with silicone grease.
For Irrigation Mode, set DIP switch 7 ON and set the
other switches to the desired watering amount.
See
the switch table on page 4 for the other Irrigation
settings.
The Rain Gage must be assembled when dry. Any
water trapped inside can condense and cause corrosion.
You may optionally add extra desiccant packets (not
supplied.) If the Rain Gage is not subject to splashing or
sprayed water, you may optionally vent the enclosure by
drilling a 1/8” (3 mm) hole in the bottom of the case.
