Precautions, Range Setup
Precautions
WARNING! All wiring must be performed by a qualified electrician
or instrumentation engineer. See diagram for terminal designa-
tions and wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or remov-
ing or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un élec-
tricien ou ingénieur en instrumentation qualifié. Voir le dia-
gramme pour désignations des bornes et des exemples de
câblage. Consulter l'usine pour assistance.
ATTENTION! Éviter les risques de choc! Fermez le signal
d'entrée, le signal de sortie et l'alimentation électrique avant
de connecter ou de déconnecter le câblage, ou de retirer ou
d'installer le module.

Electrical Connections
See wiring diagrams. Observe polarity. If the output does not
function, check wiring and polarity.
*
Do not make any connections to unused terminals or use
them as wiring junctions for external devices. This may cause
permanent damage to the module!
Range Selection
It is generally easier to select ranges before installing the
module on the DIN rail. The tables list available settings for
excitation voltages, ranges and offsets. Any custom range
settings will be listed on the module's serial number label
Rotary switches and a slide switches on the side of the module
are used to select I/O ranges to match your application.

Switch D:
Output range
Switch E :
Set to "V" for voltage output or
Set to "I" for current output
Determine how much output in millivolts the load cell will
produce at full load. Multiply the manufacturer's mV/V
sensitivity specification by the applied excitation voltage.
For example, a load cell rated for 3 mV/V sensitivity using 10
VDC excitation will produce an output of 0 to 30 mV for load
variations from 0 to 100%.
3 mV/V sensitivity X 10 VDC excitation = 30 mV range
Excitation Voltage Setup Switch A
Refer to the sensor manufacturer's
recommendations to determine
what excitation voltage to use.
Set Excitation rotary switch A to
desired excitation voltage. See
table below.
After installation the excitation
fine adjust potentiometer may
be used to precisely trim this
voltage, if desired.
I/O Range Selection B, C, D, E
1. From the table below, find the rotary switch combination
that matches your I/O ranges and set rotary switches B, C,
and D.
2. Set switch E to "V" for voltage output or "I" for current
output.
3. For ranges that fall between the listed ranges use the next
highest setting and trim the output signal with the zero and
span potentiometers as described in the Calibration section.

Offset Switch C
Offset switch C allows canceling or taring of non-zero
deadweights or other sensor offsets such as:
Compensate for tare weights or scale deadweight to get
O
zero output when a load is on the platform.
Compensate for low-output sensors (e.g., less than 1 mV/V)
O
that may have large zero offsets. Switch C can realign the
zero control so it has enough range to produce the desired
zero output.
Raising the offset to allow calibration of bipolar sensors
O
such as ±10 mV.
O
Lowering the offset to compensate for elevated input
ranges such as 10-20 mV.
1. Switch C does not interact with
any other switch and is the only
switch needed to correct zero
offsets. Its only purpose is to
adjust or cancel effects of the
low end of the input range not
corresponding nominally to 0
mV. Setting this switch to "0"
results in no offset.
2. To RAISE the output zero, rotate
switch C from "1" thru "7", until
the Zero control can be set for
your application.
3. To LOWER the output zero,
rotate switch C from "9" thru
"F", until the Zero control can
be set for your application.
4. If switch positions are changed,
repeat the calibration procedure
on the last page.
