Configuration 5-5
When supplying a voltage signal on any of the
analog input signal terminals, ensure that the
appropriate jumper is cut at the back of the
mounting cassette. Cutting the jumper disconnects
the 250 ohm shunt resistor.
Use FCODE 143, to display any of the analog inputs other than the
default (process value, input signal All). When the default value is
used in conjunction with FCODE 106, the value indicated is in
resealed units.

Analog Input Number
The user may configure input signals Al3 or Al4 as reference signals
DPR90~024 for the gain scheduling
function. When one of these inputs is used
as a reference signal, the user may wish to configure the selected
reference signal to appear on the digital display by setting the value
of FCODE 143 to option 4 or 5.

Analog Inputs Using DPRIOO Series
Temperature Input Module
The DPRSOO accepts either a 4-20 or O-20 mA signal from a
temperature transmitter, direct RTD or thermocouple
temperature-sensor input via a DPRIOO Temperature Input Module.
Any temperature module connected to the controller sends its input
signal via the All terminals, disabling All for any other input.
When a temperature input module is present, ensure that Jumper 1 is
cut and Jumper 5 is intact. Set FCODE 119 to Option 2 (Al 1 signal
range G20 mA). Also select the appropriate option for FCODE 118.
