Check SIM Sensor Connections

Open the SIM Box

1. Locate the white box with the solar

panel containing the SIM on the front of

the ISS unit. The cabled model does not

have a solar panel.

2. Locate the white tab at the bottom cen-

ter of the SIM box cover.

3. Lift the tab away from the box while

sliding the cover up.

Look on the side of the SIM box. The

box cover can be easily removed from

the box when the alignment indicator

on the cover is lined up with the align-

ment indicator on the box

4. Lift the cover off the box, being careful

not to stress the solar panel cable when

removing the cover.

The SIM and sensor connectors are

visible once the SIM cover has been

removed.

Note: See “SIM Board Display and Contents” on page 29 for information on locating the components

and points of interest on the SIM board.

Optional: Disconnect the solar panel

connection

The solar panel on the box cover is

connected to the SIM by a wire. If the

cover cannot be set aside while still

connected to the SIM box safely, it

should be disconnected from the SIM

box. To disconnect the solar power

connection:

1. Locate the brown connector for the

solar power wire.

2. Pull the connector outward off the

brown solar power tab. The solar

panel is no longer connected to the

SIM.

3. Set the SIM cover aside.

Check the Factory Installed

Sensor Connections

1. Verify that the rain collector and temperature/humidity sensor cables are plugged

into the receptacles labeled RAIN and TEMP/HUM on the SIM.

2. If the station includes UV and/or solar radiation sensors, verify that the sensor

cables are plugged into the receptacles labeled UV and SUN on the SIM.
