Furnish and install, where shown on the drawings or where
directed, a Rain Bird ON-SITE weather station, for the purpose
of monitoring daily weather conditions.
The weather station shall be a Rain Bird Model WS-PRO-SH,
direct communication, hard-wired station or a Rain Bird Model
WS-PRO-PH telephone communication type station, as shown on
the drawings and as hereinafter specified. The weather station
also is available in a solar-powered version (WS-PRO-SOLAR).
The weather station shall be as furnished by Rain Bird Sprinkler
Manufacturing Corp., Glendora, California 91741, U.S.A.
Model WS-PRO-SH Direct Wired Weather Station—Furnish
and install a Rain Bird Model WS-PRO-SH (short-haul) direct
wired weather station, located where shown on the drawings
and/or where directed. The unit shall have a sturdy, lightweight
aluminum pole and cross arm with white, epoxy powder coat
paint finish. The unit shall also have a sealed, moisture-resistant
enclosure housing the battery, micrologger for recording hourly
sensor data, and communication peripherals.
The micrologger itself shall be capable of storing a minimum
of two (2) months of data; the specific time frame of available
data shall range from seven (7) days to two (2) months, depending
on weather station programming and Rain Bird central control
options. A battery pack and a battery recharge circuit, as
well as connection terminal blocks for AC or solar power shall
be located inside the weather station enclosure. Communication
peripherals mounted inside the enclosure will also attach
to terminal blocks, or in the case of the phone modem, a RJ-11
jack. The weather station will come with a separate communication
cable that plugs into the back of the enclosure and will be
used to interface with incoming direct wire for short haul
modem connection, or with a phone line for the phone modem
option. The sensor instruments shall be mounted on the cross
arm, nine (9) feet above the ground. The sensors shall be
connected to the micrologger by water-resistant cables, which
run inside the cross arm to the back of the enclosure and
have quick-disconnect connectors to the sensor devices. The
enclosure shall be equipped with serial (I/O) connectors (not
RS-232 compatible) for use with a remote keyboard and cable
for checking sensors at the weather station itself for ease
in troubleshooting.
The weather station shall have the following sensors: wind
direction, wind velocity, solar radiation, air temperature,
relative humidity, tipping bucket rain gage, and internal
enclosure humidity. Weather station software shall be capable
of directly monitoring and displaying, on the computer screen,
the current weather conditions and calculate the "ET"
value for the past 24 hours. It shall also provide some self-diagnostics,
such as a sensor to indicate the percent of relative humidity
within the enclosure and an automatic display of the battery
voltage.
The WS-PRO-SH shall be complete with a 120VAC/16VAC 30W transformer
and a short-haul modem. The station shall be securely mounted
on a poured concrete base. The weather station will be secured
from vandalism with a chain-link, 6' high security fence with
a lockable access gate, placed a minimum of 8' out from the
weather station, on all sides and such that it will not interfere
with the accuracy of the sensor devices.
Install the transformer in a weatherproof location and run
two #14 gauge (or larger), type "UF" power wires
from the transformer to a valve box at the base of the weather
station. The weather station comes with an additional power
cable and direct burial splice kits to go from the valve box,
up through the weather station pole, to the enclosure. The
short-haul modem shall be installed at the computer location
and connected to a serial port on the computer.
Install an underground communication cable (maximum length
of 20,000 feet using 16 gage wire) between the central control
short-haul modem and a valve box at the base of the weather
station. The wire shall be __________ PE39 or Annixter F-02P22BPL
direct burial cable. Cable shall consist of at least three
(3) twisted wire pairs with a metal shield for each twisted
pair. Two of the twisted pairs will be used for the communications,
between the central control computer and the weather station.
The third twisted pair shall be maintained as a spare pair.
The additional twisted pairs are not to be used for connecting
to AC power. All shield wires MUST go to an earth ground at
one end of the communication path but not at both ends. The
weather station comes with direct burial splice kits and an
additional communication cable with leads on one end and a
plug on the other for going from the valve box to a mating
quick-disconnect plug on the back of the enclosure.
The WS-PRO-SH, including the short-haul modem, shall be installed
in strict accordance with drawings and installation data furnished
in the Rain Bird Weather station Model PRO manual "GT27145."
All equipment shall be protected and grounded using MSP-1
Surge Arrestors and MGP-1 Grounding Plate Assemblies, as shown
in detail in this publication. Also ground the Weather Station,
using a #10 gauge or larger bare copper ground wire, connected
to the Weather station enclosure ground lug and routed and
connected to one rod of a 3-rod grounding grid, using a brass
clamp.
