TurfWeather Weather Station
6.9.9 Main Electronics Board (Motherboard) Replacement Procedure
This removal and replacement procedure for the main electronics board
requires the main body of the weather station to be opened. The person
replacing this sensor should observe basic electrostatic discharge (ESD)
precautions (described below) to avoid damage to the weather station
electronics inside the main body of the weather station.
Tools Required:
• 1/2-inch wrench
• 5/16-inch wrench
• #2 Phillips screwdriver
1. Main Electronics Board Removal:
a. Follow steps provided in Section 6.9.1, Removing the TurfWeather
Station from a Mast or Pole.
b. Bring the weather station to an enclosed location, preferably near the
host computer, and place it on a flat stable surface with an area of at
least three times the size of the weather station base.
c. Invert the weather station main body and rest it on a support that
eliminates any stress on the wind speed or wind direction sensors
and/or the rain gage. A rolled bath towel placed in the center of the
main body, next to the rain gage, will generally suit the purpose.
d. Remove the seven Phillips head screws on the base of the main body
that hold the base section to the electronics enclosure section. Do not
remove the Phillips head screws that connect the mast bracket to the
weather station base. Notice that the three screws along the end with
the wind sensors are shorter than the remaining four screws.
e. Gently separate the electronics enclosure and base sections of the
weather station main body, taking care not to place any stress on the
wires that connect the two sections.
