Installing the Temperature/Humidity Sensor Replacement Kit

The Temperature/Humidity Sensor Replacement Kit works with both the ISS and Temperature/Humidity stations.

The ISS assembly for Vantage Pro2 stations (# 6152, 6152C, 6162 and 6162C) contains the rain cone, Sensor Interface Module (SIM) housing, and the radiation shield plating which houses the Temperature/Humidity sensor. The ISS is also available with extra optional components like the UV and Solar Radiation sensors and mounting bracket if you have purchased a Vantage Pro2 Plus (# 6162, 6162C) unit or have purchased these items separately.

ISS

The Temperature/Humidity Station (# 6382) contains a Temperature/Humidity sensor in a radiation shield and connects to a provided SIM shelter.

Optional — Put Console in Setup Mode

If you have a console, you need to put it in Setup Mode. This prevents the reception of erroneous data while you are removing the ISS. To put your console in Setup Mode:

• At your Vantage Pro2 console, press and hold DONE and then press the down arrow ( - ) to put the console in Setup Mode. The “Receiving from...” screen will display.

Note: Additional information on clearing and setting console data can be found in the

Vantage Pro2 Console Manual.

If you have an Envoy and are concerned with erroneous data, you may edit the data via the WeatherLink software. See the WeatherLink Online Help for more information.

Take Down the ISS

Please work on your Vantage Pro2 ISS in a safe place. We strongly recommend that you take the station down from its sited location before replacing the sensor.

To take down the ISS:

1. Locate the SIM housing cover on the side of the ISS and open it.

2. Disconnect the Solar Panel wire on the SIM cover from the SIM board by

pulling the Solar Panel connector.

3. Pull the foam insert out of the cable access port in between the cables and

set the foam insert aside.

4. Disconnect the anemometer cable from the sensor connector labeled

WIND and slide the cable out of the cable access port.

Cabled ISS Only: Disconnect the console cable from the SIM.

6. You can now remove the ISS from its mounted position. Move it to a safe

place to install the sensor.

Disassemble the Standard Radiation Shield — ISS

Note: We recommend using a workbench or table to perform the following procedures.

1. Open and remove the SIM cover if you have not done so already.

2. Disconnect the TEMP/HUM cable from the SIM

and slide the cable out of the cable access port.

3. Remove the rain collector cone from the ISS base

by rotating the cone counter-clockwise. When the cone’s latches line up with openings in the base, you can lift the cone off. The cone fits in the base

Twist to Open

tightly and may require extra pressure to remove.

Steady the ISS base between your knees when removing the cone.

4. Remove the three 8-32 x 4

screws holding the radiation shield plates together from the top of the rain collector base.

5. Separate out the radiation

shielding plates to locate the Temperature/Humidity sensor in the plating. See “Remove the Previous Temperature/ Humidity Sensor” on page 4 for instructions on removing the previous sensor.
