Polarity Selection

The default polarity is shown in the picture on
the left. To reverse the polarity, simply move the
jumpers to the positions shown on the right.

Input Range Jumpers

The input value range is from 0.5 to 4.0 mV/V
(based on 10VDC excitation). Select the input
value closest to your input range by soldering the
corresponding jumper. Span trim maybe required
in some cases.

Current Output Selection

To change the current output, solder the jumper
in the fashion described in the table below:

Pin# Wiring Code

2 + Signal

3 - Signal

* NOTE: For

6-wire connec­tions, jumper
the Sense
wires with the
Excitation
wires.

4 - Excitation

Span Trimming Adjust:

Needed when sensor sensitivity
needs to be adjusted to a specic
output to meet CSG signal require­ments. Eg. 2.850mV/V to 2.000mV/
V. Note that ETR jumper must be
open to use these options.

Zero Shift:

Causes positive or negative zero
shift for a bi-directional single ended
voltage setup. Eg. 4-20mA Where
12mA is ZERO LOAD.

Shunt Resistor

The shunt resistor is attached in the
location marked ‘RSH’ (shown above).
To change the resistance value, simply
solder your desired resistor into the

‘RSH’ location.

D

Excitation Jumpers

There are two excitation values avail­able on the CSG, 10 VDC (default) and
5 VDC. To select your excitation, simply
connect the corresponding jumper.

* NOTE: Only one excitation jumper can be con-

nected at the same time.

Shunt

It is NOT neces­sary to open the
CSG amplier
to activate the
shunt feature.
Simply press
the button
through the
cover in the
location marked
‘SHUNT’.

Span Adjust

Zero Adjust

Adjustments to the Span and
Zero are made by using a
ne pitch screwdriver to ad­just the Span and Zero pots.
