CONNECTIONS
The installer must provide cable that will connect the transmitter unit to the monitoring equipment.
Use 4-conductor cable for the 200-WS-23 Wind Speed and Direction transmitter. Use 2-conductor
cable for the 200-WS-23S Wind Speed Only transmitter. If the cable is shielded, connect the shield at
the monitoring equipment end only. The wire gage of the cable depends on the length of cable and the
applied loop voltage. Ensure the applied voltage is at least 8 volts at the transmitter circuit board at full
scale (20mA) operation.
The transmitter is provided with a green earth grounding wire which must be connected to protect the
electronic circuitry. If the wire must be extended, use 18 AWG wire.
Refer to Appendix A for wiring the 200-WS-23 Wind Speed and Direction transmitter
Refer to Appendix B for wiring the 200-WS-23S Wind Speed Only transmitter
1.
Remove the cover of the transmitter unit and set it aside.
2.
Insert the wind speed sensor cable into the same gland as the green earth grounding wire.
Provide some slack so that the wires can be connected without putting strain on the cable.
Tighten the gland nut.
3.
Make sure there is a drip loop below the transmitter enclosure so that any moisture on the
cable will not seep into the enclosure. This is particularly important since the seal around the
grounding wire and cable will not be watertight. If a watertight seal is required, apply plumber's
putty (not supplied) to the cable before tightening the gland nut.
4.
Connect the anemometer wires as indicated in Appendix A or Appendix B.
5.
Prepare the output cable by cutting back the outer jacket about 4 inches, then stripping the
wire ends. Insert the output cable into the remaining gland until the jacket is visible inside the
enclosure, then tighten the gland nut. Provide a drip loop for this cable also.
6.
Wire the Wind Direction transmitter and record the wire colors
a.
Terminal 1 is the 8-30 Vdc input (+)
Wire color _______
b.
Terminal 2 is the 4-20 mA Wind Direction signal
Wire color _______
7.
Wire the Wind Speed transmitter and record the wire colors
a.
Terminal 3 is the 8-30 Vdc input (+)
Wire color _______
b.
Terminal 4 is the 4-20 mA Wind Speed signal
Wire color _______
8.
Disconnect power from your monitoring equipment before wiring the current loop
transmitter(s). Ensure that the 4-20 mA channel(s) on the monitoring equipment are
programmed appropriately. Connect and verify all wiring before restoring power to the
monitoring equipment.
9.
Secure the cables with cable ties as required to complete the installation.
