Checking the RDC control unit - A/D Silo card communications

You can verify that the connection between the RDC unit and the A/D SILO card has
been done correctly and that the data received from the A/D SILO card is without errors.

In the A/D SILO box, remove the jumpers SILO1 and SILO2 from the card.

Enter the Setup screen and scroll to the Prov. Data screen (on page 166).
If the Prov. Data is "1234" then the connection between the A/D Silo card and
the RDC is correct.

Scroll to the Silo Data screen (see page 17). If the data for the Silo Data is "5678"
then the connection between the A/D Silo card and the RDC is correct.

Checking Load Cells

To check that the load cell is ok, disconnect all 4 wires from the connector and measure
the resistance between pairs of wires as described below.

Measured the resistance between the RED and the BLACK wires.

Measured the resistance between the WHITE and the BLACK wires.

Measured the resistance between the RED and the GREEN wires.

Measured the resistance between the WHITE and the GREEN wires.
The resistance between RED-BLACK should be exactly the same as resistance between
WHITE-BLACK. If not, the load cell is defective.
The resistance between RED-GREEN should be exactly the same as resistance between
WHITE-GREEN. If not, the load cell is defective.
Note: If the measured value is under 200 ohms, use 200 ohms range in the resistance
meter. If the measured value is above 200 ohms use the 2K ohms range.
