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 mod-

ule on the DIN rail. The tables list available settings for excita-

tion 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 input and output ranges to match your

application.

Switch A:

Excitation voltage

Switch B:

Input range

Switch C:

Input offset

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 pro-

duce 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

Switch A Excitation Voltage

Refer to the sensor manufacturer's recommendations to deter-

mine what excitation voltage to use.

Set Excitation rotary switch A to desired excitation voltage.

After installation the Excitation fine adjust potentiometer may

be used to precisely trim this voltage, if desired.

I/O Range Selection Switches B, D, E

1. From the table below, find the rotary switch combination that

matches your I/O ranges and set rotary switches B and D.

2. For taring, deadweight, zero offset, or a bipolar sensor refer

to the "Offset Switch C" section at right. Otherwise set

switch C to zero.

3. Set switch E to "V" for voltage output or "I" for current

output.

4. 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.

Using Offset Switch C

Offset switch C allows canceling or taring of non-zero dead-

weights or other sensor offsets such as:

Compensate for tare weights or scale deadweight to get

zero output when a load is on the platform.

Compensate for low-output sensors (e.g., less than 1 mV/V)

that may have large zero offsets. Switch C can realign the

zero control so it has enough range to produce a zero output.

Raising the offset to allow calibration of bipolar sensors

such as ±10 mV.

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 pro-

cedure on the last page.

Settings for Push-Pull Load Cells

The input range can be thought of as a percentage scale.

Zero percent of the signal range will be a negative number for

push-pull load cells. The high end of the signal will be a posi-

tive number. Add these together to get the span (100% of the

total signal range).

For example, if a load cell has a 1.5 mV/V sensitivity with 10 V

excitation, the range for push-pull will be –15 mV to +15 mV.

This is a span of 30 mV and we would select 30 mV as our input

range. If the range does not match up to what is in the table,

select the next highest input range setting.

For push-pull applications it is common to use a ±5 V or ±10 V

output setting. Use the table below to find your switch settings.

We also need to use "Offset Switch C" to bring the negative

end of our input range up by 50% to 0 mV. The closest setting

is position "B" 45%. This can be adjusted to 50% with the zero

potentiometer when output calibration is done.
