Connecting a CJC via a Removable Terminal Block

When using an RTB, if you choose to connect CJC sensors to your module, you
must connect a CJC sensor at the top of the RTB and one at the bottom of
the RTB.

IMPORTANT

Remember the following:

Connect the white end of the CJC sensor to the even-numbered terminals.

For CJ 0, connect the white end to terminal 2. For CJ 1, connect the white
end to terminal 36.

Connect the orange end of the CJC sensor to the odd-numbered terminals.

For CJ 0, connect the orange end to terminal 1. For CJ 1, connect the orange
end to terminal 35.

Two CJC values indicate the temperature of the top and bottom CJC sensor

CJC sensor temperatures are indicated in degrees Celsius.
