T107 Weather Station
1.
Preparation and Siting
1.1
Siting and Exposure
CAUTION
If any part of the weather station comes in contact with
power lines, you could be killed. Contact local utilities for
the location of buried utility lines before digging or driving
ground rods.
Selecting an appropriate site for the weather station is critical in order to obtain
accurate meteorological data. In general, the site should be representative of
the general area of interest, and away from the influence of obstructions such
as buildings and trees.
The weather station should not be located where sprinkler irrigation water will
strike sensors or instrument enclosure.
Some general guidelines for site selection are listed below, which were
condensed from EPA (1988)1, WMO (1983)2, and AASC (1985)3 publications.
1.1.1 Wind Speed and Direction
Wind sensors should be located over open level terrain, and at a distance of at
least ten times (EPA) the height of any nearby building, tree or other
obstruction, as illustrated in FIGURE 1-1.
FIGURE 1-1. Effect of Structure on Wind Flow
1
T107 Weather Station
1.1.2 Temperature and Relative Humidity
Sensors should be located over an open level area at least 9 m (29.5 ft) (EPA)
in diameter. The surface should be covered by short grass, or where grass does
not grow, the natural earth surface. Sensors should be located at a distance of
at least four times the height of any nearby obstruction and at least 30 m
(98.43 ft) (EPA) from large paved areas. Sensors should be protected from
thermal radiation, and adequately ventilated.
Situations to avoid include:
• large industrial heat sources
• rooftops
• steep slopes
• sheltered hollows
• high vegetation
• shaded areas
• swamps
• areas where snow drifts occur
• low places holding standing water after rains
1.1.3 Solar Radiation
Pyranometers should be located to avoid shadows on the sensor at any time.
Mounting it on the southern most (northern hemisphere) portion of the weather
station will minimize the chance of shading from other weather station
structures. Reflective surfaces and sources of artificial radiation should be
avoided.
1.2

1.5
Determining True North for Wind Vane Orientation
Magnetic declination, or other methods to find True North, should be determined
prior to installing the weather station. True North is usually found by reading a
magnetic compass and applying the correction for magnetic declination*; where
magnetic declination is the number of degrees between True North and Magnetic
North. Magnetic declination for a specific site can be obtained from a USFA map,
local airport, or through a NOAA website (Section 1.5.1, Web Calculator). A
general map showing magnetic declination for the contiguous United States is
shown in FIGURE 1-6.
Declination angles east of True North are considered negative, and are subtracted
from 0 degrees to get True North as shown FIGURE 1-7. Declination angles west
of True North are considered positive, and are added to 0 degrees to get True
North as shown in FIGURE 1-8. For example, the declination for Logan, Utah is
12.4° East. True North is 360° - 12.4° = 347.6° as read on a compass.
*
Other methods employ observations using the North Star or the sun, and
are discussed in the Quality Assurance Handbook for Air Pollution
Measurement Systems, Volume IV - Meteorological Measurements4.
Subtract declination from 360°
Add declination to 0°

FIGURE 1-7. Declination Angles East of True North Are
Subtracted From 0 to Get True North
FIGURE 1-8. Declination Angles West of True North Are
Added to 0 to Get True North
1.5.1 Web Calculator
Since magnetic declination fluctuates with time, it should be determined each
time the wind sensor orientation is adjusted. It can be accessed at:
www.ngdc.noaa.gov/geomag-web
Below is an example for Logan, UT.
8
T107 Weather Station
A positive declination is east, while a negative declination is west. The
declination in this example is 12º 24′ or 12.4º. As shown in FIGURE 1-6, the
declination for Logan, UT is east, so True North for this site is 360 – 12.4, or
347.6 degrees.

4.
Clear an area large enough to set the form at the desired elevation.
5.
Dig a hole 2 feet x 2 feet x 2 feet. Lighter soils may require a deeper hole.
About 20 inches below the top of the hole, gouge a small cavity in one
wall of the hole. The cavity should be about 4 inches deep and just large
enough in diameter to insert one end of the conduit. Make certain the
cavity “points” in the direction from which power and communications
cables will come. For example the cavity will “point” towards a valve box
if one is being used.
6.
Center the form over the hole. Adjacent to the form, drive four stakes into
the soil. Secure the leveled form to the stakes with the 8p nails.
7.
Cap the ends of the conduit with duct tape. Position the conduit and wire
into place by securing the wire to nails in the form.
8.
Fill the hole and form with approximately 1/2 yard of concrete. Screed the
concrete level with the top of the form. Center the template assembly over
the conduit and press into the concrete. Put 2 x 4 spacers between the
template and the top of the form. The bottom of the bolt threads should be
about 1/2 inch above the concrete. The template must be level in two
dimensions. Use a trowel and edger to finish.
9.
Wait 24 hours before removing the concrete form. Wait 7 days before
mounting the ET Tower.

2.1.3 AC Power Installation
a)
The currently-available AC power option includes a 100 to 240 Vac to 24
Vdc power supply (see note below). The power supply should be mounted
inside a user-supplied junction box according to local electrical codes.
Dangerous electrical accidents may be avoided by locating the transformer
remotely and burying a low voltage line to the station. The low voltage
will carry up to 500 feet on an 18 AWG power cable.
b) Shut off 110 Vac power at the main breaker. Connect the primary leads of
the power supply to the 100 to 240 Vac power source. Connect a twoconductor cable to the secondary terminals of the power supply. Route the
cable from the power supply to the ET Enclosure according to local
electrical codes.
c)
Splice the incoming two-conductor cable to the power cable provided with
the station. Use the direct burial splice kit when splices are in a valve box
or buried.
d) Connect the power plug to the connector marked “Power” on the back of
the enclosure. See FIGURE 2-21.
2.2
NOTE
The AC power supply option for older T107 stations included a
120 Vac to 16 Vac step-down transformer instead of the 100 to
240 Vac to 24 Vdc power supply. Appendix E provides
information for installing an AC power system that includes the
step-down transformer.
CAUTION
The splice and wire nut must be completely immersed into
the silicon gel inside the splice tube to be waterproof.

2.2.2 Installation
Attach the tower to the base as shown in FIGURE 2-4.
1.
Dig a hole close to the concrete base to access the lower conduit opening.
From the hole, trench to the power and communications sources. Remove
the duct tape from both ends of the conduit.
2.
Remove the template. Slide the bottom and top half of the pole pieces
together. This is a permanent connection and cannot be taken apart once
they are put together. If a little more force is necessary to put the two
halves together, then get a small block of scrap wood and a hammer. Set
the pole upright on a grassy area or have someone hold the pole
13
T107 Weather Station
horizontally. Place a piece of scrap wood over the very end of the top
section of the pole and gently hammer on the scrap wood to fit the two
halves together. A 1.27 cm (1/2 in) gap between the top and bottom pole
sections is acceptable. Lay the assembled pole on the ground next to the
concrete foundation.
NOTE
3.
Cut and save a 9 inch piece of 12 AWG ground wire from the 12 foot
length provided. This will be used later to attach the enclosure ground to
the lightning rod assembly (reference FIGURE 2-6).
4.
Thread communication cable, power cable with connector ends of cable
out the top of tower, and grounding wire through the tower and conduit.
Electrical fish tape will help. Leave approximately two feet of the
supplied power and communication cable hanging out of the top of the
pole. Secure all wiring so it doesn’t slip back down through the pole.
Solar panel and RF options will not have power or communication
cables.
5.
Place the white tower cap over the tower end.
6.
Raise the tower on a still day. Place a washer on top of the two nuts on
each foundation bolt. Taking great care not to damage cables between the
tower and conduit, raise the tower and lower it onto the conduit and
mounting bolts. Install a washer and nut on each bolt and hand tighten.
Check plumb of the tower by placing a level on the north and east sides of
the lower tower section. Adjust the topmost of the two lower nuts
(leveling nut) on each bolt as necessary. When plumb is established, lock
the leveling nut in place by tightening the lowest nut against it. Tighten
the three top nuts with the wrench.

FIGURE 2-26. Short-Haul Modem Wiring Diagram
2.5.4 RF450 900 MHz, 1 Watt Spread Spectrum Radio
The RF450 is a license free 1 watt spread spectrum radio. Communication is
strictly line-of-sight. Communication distance is dependent on antennas,
cabling, and terrain (please note that line-of-sight obstructions and RF
interference will affect transmission distance).
2.5.4.1 Power Considerations
AC power is recommended when using RF450 radios with the station. A 10
watt solar panel can be used but days without sunlight and winter months with
little sunlight should be considered. The T107 station comes with a 7 amp-hour
battery that is NOT designed to handle deep discharge. Discharging the battery
below 11 Vdc may require battery replacement. Below are some examples of
power calculations. Battery current consumption is based on discharging the 7
36
T107 Weather Station
amp-hour battery to 80% capacity (5.6 amp-hours). Discharging the battery
past this value could result in damaging the battery.
Polling the station once every 10 minutes and staying on line with the station
for one minute consumes approximately 1.276 amps over a 24 hour period. If
the station were to lose power it could run for around 4.3 days (105 hours)
before damaging the battery. A station with a 10 watt panel would need at least
3 hours of sunlight every day to keep the battery charged. Recommendation
here would be to decrease the power output of the radios or add a PS24 power
supply and enclosure with a 24 amp-hour battery below the main enclosure.
See Appendix B, PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure, for
mounting options and information on the PS24.
Polling the station once an hour and staying on line with the station for one
minute consumes approximately 0.388 amps over a 24 hour period. If the
station were to lose power it could run for around 14 days (346 hours) before
damaging the battery. A station with a 10 watt panel would need at least 1 hour

the South as much as possible. Rotate wind sensor to realign as
needed.
5.
NOTE
Use the following procedure to install the 14205 Yagi antenna for the
RF450. Installation of the 14221 Omni antenna is similar. See FIGURE
2-36.
Mounting hardware that comes in the box with the Yagi antenna
will not be used.
i.
Slide the back of the Yagi antenna into the saddle bracket. If the
Yagi antenna at the station is communicating with an
omnidirectional antenna at the base then align the tines on the
Yagi antenna so they are vertical. See FIGURE 2-34.
If two Yagi antennas are used at both ends of communication
then align the tines the same. If interference is a concern then
align the tines on the two Yagi antennas horizontally instead of
vertically. This will put the signal out of phase with other
antennas that are aligned vertically.
Tighten the nuts on saddle bracket to hold the antenna firmly in
place. Do NOT over tighten the nuts on the saddle bracket or
damage to the antenna may occur.
FIGURE 2-34. Yagi Antenna Mounted to Saddle Bracket

may have to flip the adjustable angle bracket over to get the
antenna and saddle bracket to point correctly in the vertical
direction.
43
T107 Weather Station
iii. Adjust the antenna cable at the BNC connector so the cable cover
fits over all the sensor cables as well as the antenna cable. You
may have to gently bend the antenna cable to put a 90° bend by
the BNC connector end of the cable. Take the cover off when
you’re done.
iv. Use one of the black wire ties to strap the antenna cable to the
bundle of sensor cables.
v.
Tighten up the wire ties holding the antenna cable to the wire tie
mount at the top of the enclosure.
vi. Take one black wire tie and strap the antenna cable to the antenna
as shown in FIGURE 2-35. Leave a little slack on the cable
between the wire tie and the antenna connector so as not to stress
the connector/cable connection.
vii. Make sure there is a loop of antenna cable directly under the Yagi
antenna. This will act as a drip loop and allow moisture to run off
the antenna and cable. See FIGURE 2-35.
viii. Wire tie the antenna cable to the pole. Clean up the wire ties and
put the cable cover back on.

Tighten down the wire ties holding cabling to the wire tie harness and clip
off any excess. See FIGURE 2-46.
2.9.2 Sealing and Desiccating the Enclosure
The ET Enclosure is supplied with two desiccant packs. The desiccant
maintains a low humidity in the enclosure to minimize the chance of
condensation on the instrumentation. Desiccant should be changed when the
internal ET Enclosure humidity sensor measures 50% or higher. Install the
desiccant as shown in FIGURE 2-47. Keep unused desiccant tightly sealed in
an airtight container.
NOTE
Putting desiccant into the station should be the very last thing that
is done after all other weather station installation steps have been
completed.
1) Take the desiccant packs out of the plastic bag. Strap the packs into the
desiccant holder inside the lid of the enclosure using the two Velcro straps.
2) Be sure to close the enclosure hasp securely. A padlock may be used on

ET Software
NOTE
The T107 comes with a default program, and typically does not
require additional programming (see Appendix D).
A variety of different software packages are available to work with the T107
station. This section introduces software packages that can be used with the
T107 station. It is not the goal to fully explain capabilities of each package. All
software packages mentioned below come with extensive help files. Contact
Campbell Scientific with questions and support. All software includes
installation instructions.
For Toro T.Weather 3.0 or higher, contact Toro NSN for support at (800) 2758676.
PC200W is free software which is used to communicate with a direct connect
or short-haul modem station and collect data. PC200W software cannot be used
to communicate with stations on a phone modem. This software can be
downloaded from Campbell Scientific’s website www.campbellsci.com.
54
T107 Weather Station
VisualWeather version 3.0 or higher is designed to work with the T107 station
and can be used to create programs, monitor present conditions, collect data,
and create reports and graphs. VisualWeather is designed to be a very user
friendly program. No datalogger experience is needed to use it. VisualWeather
will communicate with a direct connect, short-haul modem, RF radio, or phone
modem station. Call Campbell Scientific for pricing.
LoggerNet is a very powerful versatile package that requires some experience
with datalogger programming. LoggerNet is used to create custom
programming for the station as well as handling large networks of stations.
LoggerNet is not as easy to use as VisualWeather. Call Campbell Scientific for
pricing.
NOTE

At default settings, the Campbell Scientific software packages will
not work alongside of Toro T.Weather. Contact Campbell
Scientific.
Maintenance, Troubleshooting, and Schematics
4.1
Maintenance
Proper maintenance of the T107’s 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 or the manufacturer.
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.
4.1.1 Pole
Periodically check the tower for structural damage, proper alignment, and for
level/plumb.
4.1.2 Power Supply
4.1.2.1 Batteries
Rechargeable power supplies should be connected to an AC transformer or
unregulated solar panel at all times. The PS100 charge indicating light should
be “ON” when voltage to the charging circuitry is present. The charge
indicating light runs independent of the power switch. Be aware of battery
voltage that consistently decreases over time, which indicates a failure in the
charging circuitry. Toro T.Weather software displays the battery voltage.
4.1.2.2 Solar Panel
An occasional cleaning of the glass on the solar panel will improve its
efficiency. Use warm mildly soapy water and a clean cloth. Rinse with clean
water.
55
T107 Weather Station
4.1.3 Desiccant
Humidity is monitored inside the T107’s enclosure using the Elan HM2000 (pn
10070) RH sensor that is incorporated in the enclosure. Change the desiccant
packs when the enclosure RH exceeds 50%. The enclosure RH sensor should
be changed every 5+ years. The enclosure RH is displayed in Toro T.Weather
software.
Desiccant packs may be ordered in quantity of 20 individually sealed packs at a
time (pn 6714) or by the individual pack (pn 4905). Campbell Scientific does
have a $50.00 minimum charge. Any orders under $50.00 require a $15.00
handling fee. Call Campbell Scientific or your local Toro distributor for pricing.
4.1.4 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. See Appendix A for an example of a maintenance log file. Log
file is for one year of station use.

CAUTION
Check the solar radiation sensor (pyranometer) for level and
contamination. Gently clean with blast of dry air, soft camel hair brush, or
clean water if needed.
Handle the pyranometer carefully when cleaning. Be careful
not to scratch the surface of the sensor.
•
Do a visual/audio inspection of the 034B-ET’s anemometer at low wind
speeds. Worn bearings can cause the wind cups to spin in an uneven
manner and/or make a grinding sound.
•
Check the WindSonic1-ET for contamination. If needed, gently clean the
WindSonic1 with a cloth and mild detergent.
When cleaning the WindSonic1, do not use solvents and
avoid scratching the sensor.

your local Toro distributor for service.
•
Replace 034B-ET wind speed (anemometer) reed switch (pn 13764) if
needed. Contact your local Toro distributor for service.
•
Check calibration of the HMP60-ETS temp/RH probe. Sensor will tend to
drift up over time giving readings higher than 100%. Replace RH chip (pn
9598) if necessary (see FIGURE 4-1 and Section 4.1.4.1, Procedure for
Removing RH Chip).
T107 stations began shipping January 2014 with an updated gill

and leave it off for 5 to 10 minutes before putting in new desiccant. While
the lid is off the enclosure, compare the internal enclosure humidity to the
air humidity. Replace if > 10% off.
4.1.4.1 Procedure for Removing RH Chip
1. Unscrew the protective cap (see FIGURE 4-1).
2. Hold the plastic sides of the RH chip and unplug it.
CAUTION
To prevent scratching, avoid touching the silver chip, and
handle the RH chip with care.
3. Rinse off the RH chip with distilled water or dispose of the old RH chip.
4. Hold the sides of the rinsed or new chip and plug it in.
5. Screw on the protective cap.
4.1.5 CR1000M Module
The CR1000M Module contains a lithium battery that operates the clock and
SRAM when the module is not powered. The CR1000M does not draw power
from the lithium battery while it is powered by a 12 Vdc supply. In a T107
stored at room temperature, the lithium battery should last approximately 10
years (less at temperature extremes). Where the T107 is powered most or all of
the time, the lithium cell should last much longer.
While powered from an external source, the module measures the voltage of
the lithium battery daily. This voltage is displayed in the status table. A new
battery will have approximately 3.6 volts. The CR1000 Status Table has a
“Lithium Battery” field. This field shows lithium battery voltage.
58
T107 Weather Station
Replace the battery when voltage is approximately 2.7 V. If the lithium cell is
removed or allowed to discharge below the safe level, the T107 will still
operate correctly while powered. Without the lithium battery, the clock will
reset and data will be lost when power is removed. Contact your local Toro
distributor.
CAUTION
Toro recommends factory replacement of the lithium
battery. Misuse of the lithium battery or installing it
improperly can cause severe injury. It is a fire, explosion,
and severe burn hazard! Do not recharge, disassemble,
heat above 100°C (212°F), solder directly to the cell,
incinerate, nor expose contents to water. Lithium batteries
need to be disposed of properly.
The lithium battery contained inside of the T107’s canister is pn 13519.

2.
Check Network IDs of all RF450s; they should be the same.
3.
Check Frequency Key Number of all RF450s; they should be the same
unless two branches of the network are operating in a parallel manner.
4.
Check the “Repeaters Used” box for all RF450s.
5.
Check the PakBus address of dataloggers connected to RF450s and in
LoggerNet.
6.
Check that antenna and antenna cables are SMA (SubMiniature version
A). They will have a yellow heat shrink label to distinguish them from
RPSMA (Reverse Polarity SubMiniature version A) devices. RPSMA
antennas and cables are not compatible with the RF450.
LEDs flash when LoggerNet command transmitted but no response from
datalogger:
1.
Check SC12 cable on the datalogger’s CS I/O port.
2.
Check SDC address in RF450.
3.
Check SDC address in datalogger.
4.
Check the baud rate of all RF450s; they should be the same.
5.
Check the baud rate of LoggerNet; it should match the baud rate of the
RF450s.
Using the diagnostics port.
A special FreeWave Diagnostics cable and software (pn 20625) can be useful
in troubleshooting radio problems. Contact FreeWave Inc. for more
information on using the Diagnostics cable.
4.2.7 Gill WindSonic1-ET Diagnostic Diagnostic Codes
The WindSonic outputs a diagnostic (TABLE 4-3) along with each wind
direction and speed measurement. A datalogger program can be written that
filters out all data when the diagnostic is not 0. The programs can also report
the number of good samples that were used in computing the on-line statistics.
If the total number of good samples is less than 98% of the expected samples,
the WindSonic may be in need of repair.

Appendix B. PS24 24 Ahr Power Supply
and 10 x 12 inch Enclosure
The PS24 Power Supply is typically used when the T107 transmits data via
RF450 Spread Spectrum Radios. However, the PS24 can be used for any
situation where a larger capacity battery is desirable.
B.1 S24 Components
The PS24 consists of a 24 Ahr rechargeable battery, CH100 regulator, and a 10
inch x 12 inch environmental enclosure (see FIGURE B-1 through FIGURE
B-3). The battery should be recharged via ac power or solar power. An SP10
10-W solar panel, SP20 20-W solar panel, or 14014 Wall Charger is typically
used to recharge the battery. The environmental enclosure is mounted to the
T107’s pole using the pn 18520 hanger kit.

B.2 Installation
CAUTION
CAUTION
The PS24 is purposely shipped without the battery mounted
in its bracket. Do not install the battery until instructed to do
so.
1.
Place the top enclosure bracket on the pole at approximately 40 inches
above the bottom of the pole. The bracket should be installed with the
hook side up, and facing north.
2.
Slide the strut clamps into the bracket as shown in FIGURE B-4. Tighten
the clamp so that it doesn’t move.
Do not over tighten the clamp!
FIGURE B-4. Strut Clamps in Brackets
B-4
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
3.
Place the bottom strut clamp and bracket approximately 12 inches below
the top clamp. This clamp is installed with the hook side down. The
bracket might have to be moved a little to accept the enclosure bracketing,
so don’t tighten the bracket yet. FIGURE B-5 shows the top and bottom
brackets correctly positioned on the T107 pole.
FIGURE B-5. Both Strut Clamps and Brackets on T107 Pole
B-5
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
4.
Hook the enclosure on the top bracket as shown in FIGURE B-6.
FIGURE B-6. Top Clamp Hook Side Up
B-6
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
5.
CAUTION
The bottom enclosure bracket should slide between the top lip of the
bottom strut mount bracket and the notch directly below. Move the
bottom bracket if necessary, then bolt the bottom bracket down (see
FIGURE B-7).
Do NOT over tighten the bottom bracket.
FIGURE B-7. Enclosure Mounted on T107 Pole
B-7
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
6.
NOTE
The bottom enclosure bracket has a small metal locking mechanism. Push
up on the small Phillips screw underneath the mechanism and slide it to
the left. Once in place, put a small wire tie in the hole to the right of the
locking mechanism (see FIGURE B-8).
To remove the enclosure from the bracketing, cut off the wire tie,
slide the lock to the right, and lift the entire enclosure off the
bracketing.
FIGURE B-8. Enclosure Locking Mechanism
B-8
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
7.
Install the solar panel above the 10 x 12 enclosure, and face the solar panel
south. See FIGURE B-9 for fully mounted solar.
FIGURE B-9. Mounted Solar Panel
IMPORTANT
8.
Throw a blanket or box over the solar panel to prevent any voltage output.
9.
Route the solar panel cable and power cable coming from the main T107
enclosure into the conduit at the bottom of the 10 x 12 enclosure.
Leave a loop of all cables under the 10 x 12 enclosure to act as a
drip line. Cut both cables to whatever length you need. It doesn’t
hurt to leave a loop of cable inside the enclosure.
B-9
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
10. Wire the solar panel to the CH100 terminal blocks as follows.
Solar Panel to CH100
Red: CHG
Black: CHG
NOTE
Polarity makes no difference. Connect one wire per CHG terminal
block.
11. Remove the blanket or box from the solar panel once it’s wired in place.
12. Wire the power cable coming from the T107 station as follows.
Power Cable from T107 to CH100
Red: +12
Black:
NOTE
B-10
The red charging LED indicates that the solar panel is charging
the battery. The battery will be charged regardless of the switch
position. The switch controls the voltage going to the terminal
blocks marked “+12”.
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
13. Follow the Installation of Battery procedure provided in FIGURE B-10.
Plug the battery into the connector on the CH100 marked “INT”.
FIGURE B-10. Procedure for installing and connecting battery
14. An extra loop of ground wire was sent with the station. Use it to ground
the enclosure to the grounding rod system. The external ground lug is
mounted on the bottom left hand corner of the 10 x 12 enclosure.
15. Flip the switch to “ON”, and test drive the station.
16. After everything checks out, find the gray duct putty that was included in
the enclosure supply kit. Seal the cable-entry conduit by placing putty on
the inside and outside of it. Push the putty down into the cable entries.
B-11
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
CAUTION
The enclosure needs to be sealed up tight so don’t be stingy
with the putty.
17. Put both bags of desiccant inside of the enclosure.
18. Stick the humidity indicator card on a wall inside of the enclosure.
CAUTION
Pink on the humidity indicator card means it’s time to change
the desiccant. Change the desiccant at least every year.
However, it’s often wise to change the desiccant every six
months.
19. Close the enclosure lid.

Appendix E. Step-down Transformer
Installation
This appendix is for users who have a step-down transformer instead of the 100 to 240 Vac
to 24 Vdc power supply.
User-Supplied
Valve Box
Swept Elbow
Conduit
FIGURE E-1. ET tower installation with step-down transformer
NOTE
User supplies valve box at base of station and weatherproof
enclosure for transformer. See FIGURE E-1.
1.
The AC power option at one time included a 120 Vac to 16 Vac step-down
transformer. The transformer should be mounted inside a user-supplied
junction box according to local electrical codes. Dangerous electrical
accidents may be avoided by locating the transformer remotely and
burying a low voltage line to the station. The low voltage will carry up to
500 feet on an 18 AWG power cable.
2.
Shut off 110 Vac power at the main breaker. Connect the primary leads of
the transformer to 110 Vac following instructions provided with the
transformer. Connect a two-conductor cable to the secondary terminals of
the transformer. Route the cable from the transformer to the ET Enclosure
according to local electrical codes.
3.
Splice the incoming two-conductor cable to the power cable provided with
the station. Use the direct burial splice kit when splices are in a valve box
or buried.
E-1
Appendix E. Step-down Transformer Installation
4.
CAUTION
E-2
Connect the power plug to the connector marked “Power” on the back of
the enclosure. See FIGURE 2-21.
The splice and wire nut must be completely immersed into
the silicon gel inside the splice tube to be waterproof.
