TurfWeather Weather Station
3. Principle of Operation:
a. A Yagi high gain antenna is a directional RF device designed to
minimize signal attenuation at the base station location, thereby
providing the maximum available energy at the antenna for
communication with the remotely located equipment (i.e.: the weather
station). This antenna does need to be aimed and the best result is
obtained with a clear line of sight to the remote transceiver. If you can
see the weather station, the system has a clear line of sight.
b. The Polyphaser senses the presence of a high voltage electrostatic
energy pulse and passes it to earth ground before it can damage the
RF401.
4. System Test:
a. Initiate the system software and verify that the RF401 will
communicate with the weather station. See “TurfWeather Quick Start
Guide”
IMPROPER GROUNDING OF THE SYSTEM WILL
COMPROMISE ALL PROTECTIVE COMPONENTS AND
RESULT IN SYSTEM DAMAGE IN THE EVENT OF AN
ELECTROSTATIC DISCHARGE EVENT. THE GROUND
SYSTEM SHOULD BE REVALIDATED ON AN ANNUAL
BASIS TO ASSURE THAT CORROSION AT CONNECTORS
HAS NOT COMPROMISED THE GROUND SYSTEM. NOTE
3.11 Battery Pack (P/N 14159) Removal and Replacement
Procedure
The removal and replacement of a TurfWeather weather station battery pack
does not require training, special tools, or test equipment. However, the main
body of the weather station does need to be opened, and the person replacing
this battery should observe basic electro-static discharge (ESD) precautions
(described below) to avoid damage to the weather station electronics inside the
main body of the weather station. There is no personal electrical hazard
involved, and this procedure can be accomplished by anyone possessing basic
mechanical skills. Please read this entire procedure before beginning work.
Tools Required:
9
½ inch wrench
9
5/16 inch wrench
9
#2 Phillips screwdriver
9
Small wire cutter
1. Preparation:
a. Turn the power switch on the weather station to the “OFF” position.
b. Disconnect the power input cable and ground wire connections from
the weather station, using the 5/16 inch wrench for the ground wire
connection.
