Technical Reference Manual, General
to 1000 per mille of the range selected for the input and the y-axis is the scaled
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 machine 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.
5.1.9.6. Transducer connections
The RTD/analog 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 (analog 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.
