Getting Started Page 3

ETTING

TARTED

Follow the steps below to install your station. At various stages of this installa-

tion, you will be advised to test the system to ensure proper functioning.

1. Detach and remove the extension tube from the support tube by cutting the two

black cable ties.

2. Attach the anemometer arm to the support tube as shown below. Make sure that the

anemometer is positioned over the white ﬁeld case and NOT over the black rain col-

lector cone.

3. Attach the wind cups to the anemometer.

Push the wind cups onto the shaft as far as they will go, then tighten the set

screw. The cups should drop slightly and into the ideal position automati-

cally. Spin the wind cups. If they do not spin freely, loosen the set screw and

lower the cups slightly. Repeat until the wind cups spin freely.

4. Detach the rain collector cone and snip the cable tie.

Detach the black rain collector cone from its base by rotating the cone

counter-clockwise until its latches line up with the latch openings in the base

and then lift the cone off. (The cone ﬁts tightly and may require extra pres-

sure to remove it the ﬁrst time.) C

arefully cut and remove the black cable tie

which holds the bucket in place during shipping.

Do not re-attach the rain collector cone at this point; you will need to test the

tipping bucket before you complete the installation.

5. Apply power to the station console.

To power up the console, ﬁrst remove the console’s mounting base by press-

ing down on the large tab between the two oblong holes on the base’s

underside and pulling the base free. Plug the power adapter into the center

“Power” slot, as shown below, and then plug the other end into a 110 VAC

outlet. Once power is applied, the console should beep twice within 10 sec-

onds if the console is working properly. (If you have the optional Weather-

Link installed, the console should beep three times within 20 seconds.) The

readings will appear dashed out until you connect the sensors.

Note:

If you are going to use a battery as backup, make sure that you plug in the AC power before

installing the battery. Powering up the console with the battery alone may cause the console

to lock up due to insufﬁcient power. (Do NOT use a backup battery if you use the optional

EZ-Solar Power Kit.)

Twist off the rain collector cone.

Snip the black cable tie.

6. Connect the sensor array ﬁeld case to the console.

Plug the free end of the 100’ (30 m) 8-conductor cable on the sensor array

into the jack labeled JUNCTION BOX underneath the console.

The pre-assembled EZ-Mount station allows you to install your station

without ever opening the sensor array ﬁeld case (the white rectangular

box). Inside the ﬁeld case, the sensor data passes through a junction box

then out to the console through the cable.

7. Check all of the readings on your display to be sure they appear correctly (i.e., not

dashed out).

Consult your Monitor or Wizard owner’s manual for instructions on dis-

playing the various readings. Spin the wind cups, move the wind vane, and

tip the rain bucket to verify wind speed and direction and rainfall readings.

Note that some sensor readings (e.g., wind direction, barometer, and 0.2mm

rain collectors) must be adjusted in order to read correctly; speciﬁc instruc-

tions are contained in the owner’s manual.

If the console is having problems reading the sensors, consult the trouble-

shooting guide at the end of this manual.

8. Re-attach the rain collector cone and lay the debris screen “feet-down” over the

cone’s funnel hole.

9. Unplug the console end of the 8-conductor cable.

OUR

TATION

Choosing Locations for the Sensor Array and Console

The cable that connects your sensor array to your console is 100 feet (30 m)

long. Choose a location where the cable can safely and reasonably connect

with the console. Most people install the sensor array on the roofs of their

houses, on fences, or in open ﬁelds where wind ﬂow and rainfall are unob-

structed by trees and nearby buildings, and then install their consoles inside

their houses.

Alternatively, you can mount the console in the ﬁeld case on the sensor array

itself and either check the data at the site, or use the optional WeatherLink and

run a cable to a computer. If you plan to mount the console inside the ﬁeld

case, please keep in mind that you will need to supply the console with

contin-

uous

power. To do this, you can use the optional EZ-Solar Power Kit or any

other 110 VAC,

weather-protected

power source.

Note:

The 9-volt backup battery can serve this purpose temporarily but is

not

recommended as a

long-term solution—a new battery will power the station for 24-48 hours only.

For an illustration of how to mount the console on the inside door of the ﬁeld

case, refer to the Multi-Purpose Shelter manual included with your station.

Page 6 EZ-Mount Weather Station

Mounting the Sensor Array

The sensor array has been pre-assembled for easy installation. However, you

will still need to provide a solid mounting for the sensor array. Mounting hard-

ware has been included for the most common installations (see ﬁgures below).

If you are using the optional Mounting Tripod, consult the tripod’s manual for

mounting instructions.

CAUTION:

The station’s wind direction is calibrated as if the horizontal part of the anemometer arm

were pointing south. If you plan to mount the station facing a different direction, consult

your owner’s manual for instructions on how to adjust the wind vane accordingly.

Note:

For roof mounting, we recommend the optional Mounting Tripod. If mounting on a roof, tower, or

other elevated structure without the Tripod, be sure to consider the effects of lightning, wind

loading and vibration and design the installation accordingly.

Securing the Sensor Array

After mounting the sensor array, secure the sensor array to the extension tube

as shown below.

Running the Cable to the Console

To prevent fraying or cutting of the 8-conductor cable, secure the cable so it

does not whip about in the wind. Secure it to the extension tube by wrapping

electrical tape around them both. Use cable clips or weather resistant cable ties

(see owner’s manual for illustration) to secure the cable underneath the eaves

of your house or in locations similarly shielded from rain. Make sure the cable

is secure by placing clips or ties approximately every 3-5 feet (1-1.6 m).

Note:

Do not use metal staples or a staple gun to secure the cable. Metal staples—especially when

installed with a staple gun—have a tendency to cut the cables.

Mounting the Console

1. Plug the 8-conductor cable into the JUNCTION BOX jack on the console (step 6 on

page 5).

2. Apply power to the console (step 5 on page 4).

3. For instructions on installing a backup battery, refer to your owner’s manual.

If you plan to use an EZ-Solar Power Kit, do NOT install a backup battery.

4. For instructions on mounting the console on a wall, desk, or shelf, refer to your

owner’s manual. Or, if you want to mount the console inside the ﬁeld case, see the

discussion on page 5.

ROUBLESHOOTING

While the EZ-Mount weather station is designed to provide years of trouble-

free operation, occasional problems may arise. If you experience a problem,

please check the troubleshooting tips below before calling tech support.

✦

Console does not register any rainfall

Double check that you have cut the cable tie that secures the rain bucket

during shipping. See step 4 on page 4 for instructions. Also, make sure the

anemometer is not positioned above the rain collector cone.

✦

Console does not register wind direction correctly

Check that you have either pointed the anemometer arm southward when

mounting (page 5), or that you have recalibrated the console to the ane-

mometer arm’s current direction. See the “Installing the Anemometer” sec-

tion of your owner’s manual for instructions on how to adjust the wind

vane so that the anemometer and the console are in sync.

✦

Console locks up

Insufﬁcient power during power up or a power surge may cause the con-

sole to lock up. If this occurs, remove all power by disconnecting any bat-

tery backup and the

AC/DC

power cord. Wait for 1 minute with all of the

power removed. Then re-connect the

AC/DC

power cord and listen for 2

beeps within 10 seconds.

Note:

If you have the WeatherLink installed, listen for 3 beeps within 20 seconds and then, if all

is well, try communicating with the WeatherLink using the software.

Once you receive the ﬁnal beep, install a fresh backup battery, if desired,

and put the console back into service.
