SOLAR SENSOR
• Inspect and clean the Solar Sensor
(Pyranometer) every two (2) to three
(3)months. It is best cleaned with a
blast of clean, dry air or with a soft
bristle, camel hair brush. Be careful
NOT to scratch the surface of the
sensor. DO NOT use Windex,
soap or any other cleaning agent as
it may scratch or more likely leave a
film on the surface, which will
affect its accuracy.
• In EXTREME environmental
conditions it may be necessary to
clean the Solar Radiation Sensor
(Pyranometer) on a monthly basis.
• Be sure the DRAIN hole in the side
of the sensor housing near the top, is
OPEN and free of debris.
• Re-Calibration of the Solar Radiation
Sensor (Pyranometer) should be done
every two (2) years. Return the
sensor, through your Rain Bird
Distributor, for calibration.
WIND SENSOR
• Inspect bearings and operation of the
Wind Sensor (wind speed and wind
direction) on a regular basis, at least
once a year. They should move
freely and react to a wind speed of 2
to 3 mph.
The bearings have a life expectancy of 3
to 5 years, except in very high wind
areas, where their life may only be 1
year.
• The bearings can only be replaced by
the factory and therefore need to be
returned to the factory through your
local Rain Bird Distributor.
Checking the bearings of the 034A
Wind Sensor.
• Remove the Wind Sensor from the
Weather Station cross-arm, by
removing the set screw that is
securing the sensor in the mounting
shaft and raising the sensor up and
out of the mounting shaft.
• Hold the Wind Sensor in a horizontal
position (with one of the wind speed
cups “down” toward the ground).
• On one of the cups hang an ordinary
paper clip (0.5 gm weight) on the
outer edge of one of the cups.
• Position this cup in the “up” position
and release. The cup should rotate
downward. Failure to rotate
indicates the bearings need
replacement.
RELATIVE HUMIDITY SENSOR
• The life of the RH chip is dependent
upon air quality in your area. As a
General Rule the RH chip should be
replaced EVERY 2 YEARS, if
necessary.
• In extreme environmental conditions,
the RH chip may need to be replaced
every year.
