absolute value of the input. The linearization curves can be enabled and disabled
with the “Linear. curve” parameters in the menu Configuration/RTD1/
Input # . The curve is constructed and downloaded to the feeder terminal by using
a special tool in the relay toolbox.
When the linearization curve is enabled, the “Input high limit” and “Input low limit”
parameters affect the scaled range instead of the range selected by the parameters.
The range of the scaled input is defined as the range between the smallest y-axis
value and the largest y-axis value.

The RTD/analogue inputs may be connected to a large variety of different
measuring transducer types, both standardized and customer-specified types.
Three connection screws have been reserved for each channel. Further, one
connection screw (analogue ground) has been reserved per every two channels.
Two earth terminals (see figure below), located to the left of the connectors, are
reserved for connecting the protective sheaths of the transducer input cables. The
cable sheath is generally earthed in one end of the cable only.
