Section 8: Troubleshooting
Wind Sensor Tests
In the event the wind speed is reporting zero constantly regardless of
wind conditions, is inexplicably erratic and/or the wind direction is
reporting North constantly regardless of wind conditions, or is reporting
incorrect direction, either the Control Module or the sensors (or both)
may be defective. The following tests are appropriate to help locate the
source of the problem.
Tools required:
(1) Small Phillips screwdriver
(1) 6" (15 cm) jumper wire, 22 gauge
Multi meter or volt meter
Wind Speed Test
1. Unplug the power supply cord from the Control Module.
2. Remove the seven wind sensor wires from their terminals at the
back of the Control Module.
3. Power up the Control Module.
4. With one end of the jumper wire connected to terminal #6, tap
the other end on terminal #5; the wind speed reading should
change from zero. The faster you tap, the higher the wind speed
value.
5. If the wind speed value does not change from zero, then the
wind speed channel in the Control Module is defective and the
Control Module should be returned to the factory for repair.
6. If the wind speed value changes from zero, the problem is in the
wind sensor or cable. Check the cable for damage and inspect
any cable splices. Make sure the cable connector is plugged in
the wind sensor correctly.
7. If you cannot find any problems with the cable, disconnect the
wind sensor and return it to the factory for repair.
Note: Please follow the procedure on page 76 for returning any
defective items to the factory.
