1.Introduction
This instrument is a precision digital indicator using the latest Sigma-Delta analogue to digital
conversion technology to ensure fast and accurate weight readings.
Figure 1: Weight Indicator
The setup and calibration of the instrument are digital, with a non-volatile security store for all setup
parameters.
The instrument may be operated from 9.6V, 12V or 24V batteries or a DC power source from 12V to
24V. There is a soft power on/off function that retains memory of the indicator’s state. Once an
instrument is turned on it will automatically start up again if the external power is interrupted.
The instrument is fitted with opto-LINK communications as standard. This allows a temporary
isolated communications link to be established with a PC using an opto-LINK cable, which enables
software upgrades and the use of computerised setup and calibration via the Viewer software. Refer
to opto-LINK (Optional) page 15
for more information.
The instrument comes with two different firmware types (K376 and K378). FACTRY.APP.ID can be
used to select desired firmware. Then licence code should be entered using FACTRY.L.CODE.
Refer FACTRY menu page 40 for more information.
1.1. Overview
This instrument provides ZERO and TARE functionality as well as more setup options (e.g.
serial and setpoints) and printing functionality.
It also supports special functions (e.g. peak-hold, averaging, counting, etc.), via the user
definable <FUNCTION> key. It is equipped with an NVRAM store to ensure day-to-day
operating settings (e.g. ZERO, TARE,CLOCK, etc.), are retained when power is removed.
This instrument has three isolated transistor outputs with status display and LEDs on the front
panel as well as the RS-232 communications port that can be used for printer driving or
connection to a remote display or PC. There is a built-in clock for date-stamping printed
outputs.

3. Installation
3.1. Introduction
The following steps are required to set up the indicator.
•Inspect indicator to ensure good condition.
•Use connection diagrams to wire up load cell, power and auxiliary cables as required.
•Use the panel mount template provided for hole locations.
•Connect Power to indicator and press <POWER> key to turn the instrument on.
•Refer to the Setup section page 30 for information on configuring and calibrating the
instrument.
•To turn instrument off press and hold <POWER> key for three seconds (until display
blanks).
3.2. General Warnings
•Indicator not to be subject to shock, excessive vibration, or extremes of temperature
(before or after installation).
•Inputs are protected against electrical interference, but excessive levels of electro-
magnetic radiation and RFI may affect the accuracy and stability.
•The instrument should be installed away from any sources of excessive electrical noise.
•The load cell cable is particularly sensitive to electrical noise and should be located well
away from any power or switching circuits.
•For full EMC or for RFI immunity, termination of cable shields and correct earthing of the
instrument is essential.
•Indicator and load cell cable are sensitive to excessive electrical noise. Install well away
from any power or switching circuits.
3.3. Electrical Safety
•For your protection all mains electrical hardware must be rated for environmental
conditions of use.
•Pluggable equipment must be installed near an easily accessible power socket outlet.
•To avoid the possibility of electric shock or damage to the instrument, always switch off or
isolate the instrument from the power supply before maintenance is carried out.
3.4. Cleaning
The unit has been designed for high-pressure, high temperature (80°C) wash-down environments.
However, prolonged periods of focused pressure at a close range will damage the casing. Casing is
chemical resistant

Reference Manual V1.16 Software Versions 4.xx
Page 8 003X-652-116
3.5. Cable Connections
All cable connections are made to the rear of the instrument using pluggable screw terminals.
It is not necessary to tin the ends of the wire with solder or to add crimp ferrules to the wires,
however, these techniques are also compatible with the terminals and may ultimately make
for a neater job.
Figure 2: Cable Connections
3.6. DC Power (DC PWR +, DC PWR –)
The DC supply need not be regulated, provided that it is free of excessive electrical noise and
sudden transients. The instrument can be operated from a high-quality plug-pack as long as
there is sufficient capacity to drive both it and the load cells.
If an optional battery pack is fitted, then the supplied charging system must be used.
3.7. Load Cell Connection
Load Cell Signals and Scale Build
Very low output scale bases may be used but may result in some instability in the weight
readings when used at higher resolutions. Generally speaking, the higher the load cell output,
or the lower the number of divisions, the greater the display stability and accuracy.
The instrument can display the millivolt-per-volt reading that can be used to check scale base
signal output levels. For more information, refer to TEST (Special Test Functions) page 39.
The instrument may be connected for either 4-wire or 6–wire operation. To correspond with the
actual cabling installation the instrument must be configured in setup to the correct setting. For more
information, refer to CABLE Page 33.

Reference Manual V1.16 Software Versions 4.xx
003X-652-116Page 9
4-Wire Connection
The minimum connectivity requirements are the connection of four wires (i.e. Excitation + and
–along with Signal + and –). Internally the instrument has a precision analogue switch that
connects the Sense + and –lines directly to the Excitation + and –lines when 4-wire mode is
selected.
A 4-wire connection is only suitable for short cable runs. Where long cable lengths are
needed, a 6-wire extension is required to maintain accuracy.
The BUILD:CABLE option must be set to 4 to allow for 4-wire connection. Refer to CABLE page 33.
Figure 3: 4-Wire Connections
6-Wire Connection
The excitation and signal lines are connected the same as for a 4-wire installation. The extra
two wires (Sense + and –) should be connected to the Excitation + and –lines as close as
possible to the load cell itself. Typically these connections are made in a load cell termination
box.
The BUILD:CABLE option must be set to 6 (the default) to allow for 6-wire connection. Refer to
CABLE page 33.

Ring Networks: Multiple Instruments to PC (RXD, TXD, GND)
Instruments can be configured in a Ring Network.
The Short Ring Network layout can be used in situations up to a total cable run length of
about 150 m (500 ft.) at 9600 baud in a clean EMC environment. If there are
communications errors, or for longer cable runs, lower the baud rate to 4800 or 2400,
and/or use the Long Ring Network in Figure 8 below, which uses a separate return path
from the ‘Last Instrument’ to the PC.
For DB25 connections at the PC connector, refer to Figure 6 above.
When operating in a Ring Network, the Instruments must have:
•same serial port options, i.e., baud, parity, data bits, stop bits;
•unique addresses.

Long Ring Network: Multiple Instruments to PC (RXD, TXD, GND)
The Long Ring Network layout can be used in situations where each leg of the cable run
can be up to about 150 m (500 ft.) at 9600 baud. If there are communications errors,
lower the baud rate to 4800 or 2400.

Printer Connections (RXD/TXD, GND and DTR)
Figure 9: RS-232 –Instrument to Printer (DB25)
Remote Display (TXD, GND)
The remote display documentation should be referred to for connection details. Connect
TXD to RXD and GND to GND on the remote display.
Remote Input
The indicator requires a voltage free contact between TXD and RXD to enable the
remote input (i.e. SPEC:REM.FN). The SERIAL:TYPE option must be set to AUTO,
PRINT or AUTO.PR. When using SERIAL:TYPE of PRINT or AUTO.PR, the
SPEC:REM.CHR must be set to an appropriate character that will not affect the printer.
This character will be sent repeatedly when the transmitter is idle, regardless of the state
of the DTR line. Note: The remote input will not function when in setup or when using the
opto-LINK.
Note: Auto Output Speed must be set to 10Hz.
WARNING
The remote input is a voltage free contact (e.g.
button, mechanical relay). Connection of any
active circuitry may damage the instrument.
Figure 10: Remote Input

Reference Manual V1.16 Software Versions 4.xx
Page 14 003X-652-116
Outputs
The output drivers for the instrument are high side drive and are capable of driving up to
400mA each. This configuration allows for the direct connection of the instrument outputs to
most types of PLC.
The voltage applied to the instrument’s positive power supply terminal (+) appears on the
output lines (Over, Pass and Under) when the outputs are active (e.g. to connect to a PLC
connect +24V to the common terminal). The outputs can then be connected directly to PLC
inputs.
To drive external loads (e.g. relays), connect the output line directly to the positive side of the
relay coil. Connect the negative side of the relay coil to COMMON. It is recommended that fly-
back diodes or transient suppressors be fitted across relay coils to limit switching noise.

Reference Manual V1.16 Software Versions 4.xx
003X-652-116Page 15
3.9. opto-LINK (Optional)
A temporary infrared communications link can be established between the instrument and a
PC using an optional opto-LINK cable. The optional opto-LINK cable can be used to transfer
setup and calibration information from a PC (e.g. to be stored for later use and/or transferred
to other instruments). It can also be used to download software upgrades to the instrument
from a PC.
The PC end of the opto-LINK cable is a standard female DB9 connector, or USB connector.
The instrument end of the cable consists of an infrared transceiver, which attaches to the left
side of the instrument display. To facilitate a quick and simple connection, the infrared
transceiver is secured in place by a permanent magnet located within the head of the opto-
LINK.
Refer to opto-LINK Activation page 22 for more information.
WARNING
The opto-LINK head contains a strong magnet and care should be taken with its
proximity to electronic media (e.g. credit cards, floppy disks, etc.) and/or other
electronic instrumentation.
Figure 13: opto-LINK Attachment

Reference Manual V1.16 Software Versions 4.xx
Page 16 003X-652-116
3.10. Connecting Shields
To obtain full EMC or for RFI immunity, cable shields MUST be connected to the earth lug on
the rear of the instrument.
Cable Shield Connection and Earthing
•Care should be taken when connecting shields to maximise EMC or RFI immunity and
minimise earth loops and cross-talk (interference) between instruments.
•For full EMC or for RFI immunity, termination of the cable shields at the earth lug is very
important. The earth lug of the instrument must be separately connected to ground
potential via a reliable link.
•The instrument should only be connected to earth via a single reliable link to avoid earth
loops.
•Where each instrument is separately earthed, interconnecting cable shields should be
connected at one end only. This also applies to communications cable shields in Ring
Networks, refer to Short Ring Network and Long Ring Network connections under ‘RS-
232 Serial’ pages 11 and 12.
•Caution: Some load cells connect the cable shield directly to the load cell (and therefore
the scale base). Connection of the load cell cable shield in this situation may be site
specific.
3.11. Regulatory Sealing Requirements
To comply with regulatory sealing requirements for each instrument, (i.e. to ensure instruments are
not accidentally or deliberately tampered with), it is important that proper sealing procedures be
adhered to. Refer to Appendix - Trade Sealing page 57 for more information.
