UV Sensor
Routing the Sensor Cable
Route the sensor cable through the base of the rain collector and out through a
hole, then connect it to the SIM inside the radiation shield. (This step requires
that the radiation shield is open. If it is not, remove the shield plates now as
shown in “Accessing the SIM” on page 12.)
See the illustration below as you follow these instructions.
1. Tie the sensor cable to the shelf support tube.
Use one of the plastic 4" cable ties provided with the sensor mounting shelf
to keep the cable in place. (#1 in illustration.)
2. Squeeze the cable down into the cable notch on the circular edge of the rain collector
base. The cable needs to be wedged down into the notch so it will come up inside the
rain collector cone when the cone is put back on.
3. Route the cable down and out through the hole in the base.
Plug the cable into the receptacle labeled “UV" in the SIM, to see how much
slack will be left in the cable as you secure it inside the rain collector.
4. In the rain collector base, loop up the slack in the cable. Using the two cable clamps in
the base, secure one loop.
Tie the remaining loops of cable together with cable ties #2 & 3 as shown.
When securing
the sensor cable(s)
inside the rain col-
lector base, the
goal is to ensure
that the cables do
not interfere with
the tipping
bucket mecha-
nism
of the rain
collector.
