3-1.1 So Earth

All REM devices have a so earth and as such the Earth must be connected to the terminal ‘E’. This

provides the required path to earth. It is not suicient to have the 0V earthed on the 24V powered

devices as these are separated.

3-1.2 End of Line Termination (EOL)

All REM’s have EOL jumpers and these must be fitted correctly. See the figures below.

There are many variations to network layouts the following four examples provide a guide to correct

jumper application.

EXAMPLE 1:

This example shows a GENIIELD controller with a straight forward network of REM’s.

Both ends must have the EOL jumpers fitted.
