Stretch the O-ring a few times, so that it fits
easily into the groove on the lens.
After the unit is assembled, verify that the O-ring is properly
seated by confirming that you can see it through the lens, all
the way around. The O-ring is slightly under-sized for the
groove because that gives the optimal seal.

MODEL RG-11
OPTICAL RAIN GAUGE
INSTALLING THE RAIN SENSOR
1. Determine the Mode / Set DIP switches
You must set the DIP switches so that the RG-11
behaves the right way for your application. The pages
that follow describe each of the possible modes, and
how to set the DIP switches.
2. Mount the Rain Gauge
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.
3. Assemble the Rain Gauge 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.
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.
Do not use the RG-11 in any application where the false
indication of water or a missed valid detection of water
could cause damage to life or property. It is the
responsibility of the system designer / integrator to
design redundancy into the system so that the failure of
any one component, including the RG-11 or other
sensor, does not result in disaster. The manufacturer of
the RG-11, Hydreon Corporation, will in no way be
2.17
liable for consequential damages due to the failure or
55.20
false indication of one of its sensors.
