Sensor Interface Cable Removal
and Installation
1.
Open the power supply door and turn off the power to the wind
sensor.
2.
Lower the wind mast or tower.
3.
On the adapter, loosen the single screw close to the sensor. Do not
loosen any of the three screws that are used to fasten the adapter to
the mounting tube (see
Figure 3 on page 18
). Loosening these three
screws would make a solar noon alignment necessary.
4.
Pull the sensor out of the adapter.
5.
Disconnect the cable from the sensor and gently put the sensor
some place where it can’t get hit accidentally.
6.
Open the power supply door and disconnect the sensor interface
cable (12 ring lugs). Wrap electrical tape over wires tightly folding
half forward and half bent back on cable so it can be easily pulled
through the ½” conduit.
7.
Remove the cable from the wind mast or tower. It has to be pulled
out of the conduit first and then pulled out of the top of the pole.
Tape up both tightly with electrical tape.
8.
Remove the new sensor cable from the shipping container. One end
of the cable has ring lugs. On this end take about half of the
individual wires and fold them back.
9.
Feed the cable through the adapter mounting arm, pole, pole pivot
and the conduit going to the power supply starting with the
wrapped end of the cable into the open end of the adapter as the end
of the mounting arm.
10. In the power supply, connect the 12 ring lugs of the sensor interface
cable to the 12 position terminal block.
11. Take the sensor and connect the top end of the sensor interface
cable to it. Insert the sensor into the adapter and tighten the set
screw that secures the sensor to the adapter.
12. Turn on the power switch in the power supply.
13. Connect a laptop to the TEST connector in the power supply via an
RS-232 cable.
14. Run the Diagnostics Program on the laptop. Choose the option that
connects the sensor to the laptop with system disconnected.
15. Issue a WA command. The sensor must respond with a P status.
