EXHIBIT "A"
Re: Weather Station - Model "PRO"
1.0 MAINTENANCE & TROUBLESHOOTING
GENERAL MAINTENANCE:
Proper maintenance of weather station components is essential to obtain accurate data.
Equipment must be in good operating condition, which requires a program of regular inspection
and maintenance. Routine and simple maintenance can be accomplished by the person in charge
of the weather station. More difficult maintenance such as sensor calibration, sensor
performance testing (i.e., bearing torque), and sensor component replacement, generally requires
a skilled technician, or that the instrument be sent to Campbell Scientific for repair or updating.
Contact your local Rain Bird distributor for instructions.
A station log should be maintained for each weather station that includes serial numbers, dates
that the site was visited and maintenance that was performed.
INSTRUMENTATION MAINTENANCE:
The instrumentation requires a minimum of routine maintenance. A few preventative
maintenance steps will optimize battery life and decrease the chances of datalogger failure.
BATTERIES:
RECHARGEABLE
Rechargeable power supplies should be connected to an AC transformer or unregulated solar
panel at all times.
Be aware of battery voltage that consistently decreases over time, which indicates a failure in the
charging circuitry.
DESICCANT:
Enclosure humidity is monitored in the Enclosure. Change the desiccant packs when the
enclosure RH exceeds 35%. The RH chip should be changed every 5 to 8 years.
SENSOR MAINTENANCE:
Sensor maintenance should be performed at regular intervals, depending on the desired accuracy
and the conditions of use. A suggested maintenance schedule is outlined below.
00095762/jkg
1 Week
• Visually inspect the station and all sensors. Look for any damage and debris that may
disturb sensor readings.
• Check the Pyranometer for level and contamination. Gently clean with a soft bristle
brush, if needed.
• Check and clean the Tipping Bucket Rain Gauge, especially the bucket screen and the
small funnel outlet.
To check accuracy of the rain gauge - 16 ounces of fluid is equal to 1" of rainfall. Fluid
must be poured into the gauge VERY SLOWLY to get an accurate bucket tipping count.
1 Month
• Check the Temperature/Relative Humidity Sensor for contamination.
6 Months
• Clean the Temperature/Relative Humidity Sensor.
• Check battery by disconnecting the AC Power and allow it to stabilize for at least 2
hours. Then check the voltage. Reconnect battery to AC Power.
1 Year
• Replace the RH chip if necessary.
2 Years
• Calibrate the Pyranometer (some suggest yearly).
• Replace RH chip in Air Temperature/Relative Humidity Sensor.
• Calibrate the Tipping Bucket Rain Gauge. To check accuracy of the rain gauge - 16
ounces of fluid is equal to 1" of rainfall. Fluid must be poured into the gauge VERY
SLOWLY to get an accurate bucket tipping count.
4-S Years
• Replace sensor cables as required.
General Maintenance
• An occasional cleaning of the glass on the solar panel will improve its efficiency.
• Check sensor leads and cables for cracking, deterioration, proper routing and strain relief.
• Check the tower for structural damage, proper alignment and for level/plumb.
SENSOR MAINTENANCE
RAIN GAUGE
Inspect and clean every two to three months - removing leaves, debris, etc. In extreme
environmental conditions it may be necessary to do this on a MONTHLY basis.
• Check that the tipping mechanism moves freely and that it registers 0.01 inches per tip.
• Check and re -level the Rain Bucket, if necessary.
• Calibrate the Rain Gauge every 2 years.
Calibrating the Rain Bucket:
• Secure a metal can that will hold at least one quart of water.
• Punch a VERY SMALL HOLE in the bottom of the can.
• Place the can in the top of the funnel of the Rain Bucket, and pour 16 fluid ounces (1
pint) of water into the can.
• If it takes LESS than 45 minutes for this water to run out, the hole in the can is TOO
LARGE.
• One hundred (100) tips plus or minus three tips should occur and register from 0.97
inches to 1.03 inches. (0.01 inches per each tip).
Adjusting screws are located on the bottom of the Rain Bucket, adjacent to the large center drain
hold. Adjust both screws the same number of turns or partial turns. Rotation clockwise
increases the number of tips per 16 ounces of water, counter clockwise rotation decreases the
number of tips per 16 ounces of water. One half turn of both screws causes a 2% to 3% change.
• Check and re -level the Rain Bucket lid.
Factory Calibration is available through your Rain Bird distributor.
Suggestions:
Devices for dripping water are available through a chemistry equipment supply house.
In order to see the 100 tips, configure a FAKE weather station within the weather software, to
use for this testing. Drip the water and then do an upload using the new test configuration to see
the number of tips (0.01 inches = 1 tip).
CAUTION ! Be sure to disable any Automatic Uploads, since the 100 tips will contaminate the
every day weather data.
After the calibration is complete, reset the datalogger by removing the power and the battery
connections in the Enclosure. Contact Campbell Scientific for further instructions. You will
have to reset the time of day and year in the datalogger by uploading one day of data (#6 from
the Weather Main Menu). The 7 days of data that are stored in the datalogger will be lost when
you disconnect the power, so be sure to have done an upload before you begin the calibration
process.
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.
• The best time to change the chip is at the beginning of the most critical time for watering
(spring and fall in the desert areas).
• Clean the screen, on the tip of the RH chip enclosure, every six (6) months or more often if
required. If the screen gets dirty quickly, this will reflect how often the chip will need to
be replaced.
TEMPERATURE SENSOR
• Inspect and clean, at least every 2 to 3 months and more often in extreme environmental
conditions. CAUTION - be careful of the thermister, as it is very delicate.
• Carefully clean insects and debris from the temperature probe.
• The temperature probe can NOT be calibrated, so if the readings are poor the complete
probe must be replaced.
• After several years the temperature/RH sensor may become corroded and should be
replaced.
NOTE ! Water will affect the temperature readings, so be sure no direct water is hitting the
weather station from sprinklers in the area.
SEAL OF ET ENCLOSURE
The seal on the panel assembly of the Enclosure forms the seal between the Enclosure cover and
the Enclosure back panel.
• This seal should be inspected on a regular basis, looking for cracks, hardening of the
foam rubber and/or loosening from the back panel assembly.
• Any time the Enclosure is opened, upon closing it the desiccant pack should be replaced
with a new desiccant pack.
• At least once a year the desiccant pack should be replaced with a new pack.
• The Enclosure internal moisture should be monitored. The desiccant pack maintains a
low humidity in the Enclosure and minimizes the chance of condensation on the
datalogger and other electronic components.
• The desiccant pack should be changed when the internal Enclosure humidity sensor
measures 35% or higher.
• If the moisture level gets too high the Enclosure should be opened and dried out. The
desiccant pack needs to be replaced with a new pack.
• All parts should be dried with a clean, dry cloth and components inspected for corrosion.
• When replacing the cover on the Enclosure, place the cover top into the top of the
Enclosure and be sure the cover is properly engaging in the tabs at the top of the
Enclosure. Gently close the cover and secure it with the latch at the bottom. Be sure the
latch hasp is securely latched, as keeping out moisture is dependent upon a tight seal
between the Enclosure back panel and the cover provided by the molded rubber seal on
the Enclosure back panel.
BATTERY CHECK
• At least TWICE (2 times) a year the AC power wires to the charger should be
disconnected to allow the station to operate off the batteries without the charger in
operation.
• Check the battery under these conditions to get an accurate actual battery voltage level.
• Allow 2 hours, after the battery AC recharge power has been disconnected, for the
battery to dissipate high voltage level before checking the voltage.
CAUTION ! Be sure to RE -CONNECT the battery charger and/or power wires to the weather
station after checking the battery voltage.
• The 16 VAC power or the solar panel power should be connected to the weather station
at all other times.
SENSOR TESTING
At least once a year, or whenever sensor failure is suspected, the sensors listed below should be
checked with a volt/ohm meter for ohm resistance.
• Wind Sensor - Wind Speed (Anemometer) Sensor
• Wind Sensor - Wind Direction Vane Sensor
• Rain Gauge Tipping Bucket
• Solar Radiation Sensor - Pyranometer
All sensors that are to be checked, EXCEPT the Rain Gauge, should have a measurable
resistance. INFINITE resistance indicates an OPEN circuit. Any sensor with an open circuit
needs to be repaired or replaced.
WIND SPEED SENSOR
Refer to schematic wiring diagram - located in the Appendix - FIGURE 29
• Measure the resistance from P1 to G (pins 3 to 5) of the Wind Speed Sensor. Slowly turn
the wind speed cup. The resistance should vary from infinite to less than 1 OHM as the
reed switch closes in the anemometer.
WIND DIRECTION
Refer to schematic wiring diagram - located in the Appendix - FIGURE 29
• The Wind Direction sensor varies in its resistance as the vane turns. With the OHM
meter connected to E2 and 2H (pins #1 and #2) the resistance should vary from 11K
OHMS to 21K OHMS.
• If the infinite resistance is measured, then the wiper in the potentiometer is most likely
damaged and the sensor needs to be repaired.
• With the OHM meter connected to 2H & AG (pins #2 & #4) the resistance should vary
from 1K to 11K OHMS with change in wind direction. If infinite resistance is measured
then the potentiometer is bad and should be replaced.
SOLAR RADIATION SENSOR - PYRANOMETER
Refer to schematic wiring diagram - located in the Appendix - FIGURE 30
• The Solar Radiation Sensor (Pyranometer) should measure between 40 OHMS and 90.2
OHMS, when checked with an Ohm meter between 3H & 3L (pins #1 & #2).
• Set meter for lowest DC millivolts (a very sensitive meter is required) and measure from
3H to 3L (pins #1 & #2). The small voltage should vary with variation in light intensity.
Place your hand over the sensor - should read 0 VDC.
TIPPING BUCKET RAIN GAUGE
Refer to schematic wiring diagram - located in the Appendix - FIGURE 31
• The Rain Gauge has a reed switch that closes as the tipping bucket mechanism "tips."
Connect the OHM meter across P2 & G (pins #3 & #5) and should read infinite OHMS.
When bucket mechanism is "tipped" - should then get less than 1 OHM.
• If the bucket tipping mechanism is working correctly you should read +5 Volts DC with
the meter set at DC volts and connected across the reed switch, while sensor is plugged
into the Weather Station. When the bucket is "tipped" the reed switch closes and you
should have 0 VDC. There is continuous low voltage going through this reed switch,
except as it "tips" at which time the +5 Volts DC is shorted and thus there is a possibility
of corrosion buildup on the switch over time.
• The reed switch is easily replaced and the parts are available from your local Rain Bird
distributor.
TEMPERATURE AND RELATIVE HUMIDITY SENSOR
Refer to schematic wiring- diagram - located in the Appendix - FIGURE 32
• Set the meter to DC volts and check across pins #4 & #6 for 12 VDC.
DO NOT connect an OHM meter across the RH chip or damage may occur to the RH chip. If
you are experiencing problems with the temperature and relative humidity probe -
determine the following:
• Are both the temperature and humidity readings "bad"?
• Is just the temperature reading "bad"?
• Is the RH reading "bad"?
• If just the RH readings are "bad" - then the RH chip most likely needs to be replaced.
New RH chips, for replacement, are available from your local Rain Bird distributor.
AIR TEMPERATURE PROBE (ON REDUCED SET STATION ONLY)
Refer to schematic wiring diagram - located in the Appendix - FIGURE 33
• Set meter to OHMs and measure from El to 1H (pins #3 & #1) should read a minimum
of 249K OHMS. Colder temperatures result in higher resistances.
• With meter on OHMS measure from 1H to AG (pins #1 to #5). Should have a fixed
reading of 1K OHMS resistance.
• With meter on OHMS measure from El to 1L (pins #3 to #2) should read a minimum of
249K OHMS. Colder temperatures result in higher resistances.
• With meter on OHMS measure from 1L to AG (pins #2 to #5). Should have a fixed
reading of 1K OHMS resistance.
