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 4.8V, 7.2V, 9.6V, 12V or 24V batteries or a DC
power source from 7V 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.
1.1. Overview
This instrument provides ZERO and TARE functionality as well as more setup
options (eg. serial and setpoints) and printing functionality.
It also supports special functions (eg. peak-hold, live weight (livestock) averaging,
counting, etc.), via the user definable <FUNCTION> key. It is equipped with an
NVRAM store to ensure day-to-day operating settings (eg. ZERO, TARE,CLOCK,
etc.), are retained when power is removed.
This instrument has two isolated transistor outputs with status display 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 29 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
•To maintain the instrument, never use harsh abrasive cleaners or solvents.
Wipe the instrument with a soft cloth slightly dampened with warm soapy water.
3.5. Panel Mount Template
Use the panel mount template for drill hole locations. The template indicates
positions for the two 4mm mounting screws through the panel. Also displayed on
the template is the position of the rectangular hole that should be cut to allow for the
connection of cables. The template supplied with the indicator allows for front or
rear machining of the panel.

Reference Manual Rev 3.23 Software Versions 3.xx
Page 8
3.6. Cable Connections
All cable connections are made to the rear of the instrument using screwless
terminals. Wires must be stripped of insulation by at least 10mm. To install,
depress the orange lever beside the terminal required and push wire into the hole.
Release the lever and pull gently on the wire to ensure it is securely trapped in the
terminal. 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
3.7. 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.
3.8. Load Cell Connection
3.8.1. 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 SCALE (Scale Base
Test Display) page 40.
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 (4-Wire or 6-
Wire) ⊗page 32.

Reference Manual Rev 3.23 Software Versions 3.xx
Page 9
3.8.2. 4-Wire Connection
The minimum connectivity requirements are the connection of four wires (ie.
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 (4-Wire or 6-Wire) ⊗page 32.
Figure 3: 4-Wire Connections
3.8.3. 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 (4-Wire or 6-Wire) ⊗page 32.

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.
3.9.2. Remote Input
The indicator requires a voltage free contact between TXD and RXD to enable
the remote input (ie. 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.
WARNING
The remote input is a voltage free
contact (eg. button, mechanical relay).
Connection of any active circuitry may
damage the instrument.
Figure 10: Remote Input

Reference Manual Rev 3.23 Software Versions 3.xx
Page 14
3.9.3. Outputs
The output drivers for the instrument are isolated open emitter transistor drives that
are capable of driving up to a total of 300mA. This configuration allows for the direct
connection of the instrument outputs to most types of PLC.
The voltage applied to the COM terminal appears on the output lines (ie. OUT1 and
OUT2) when the outputs are active (eg. to connect to a PLC connect +24V to the
common terminal). The outputs can then be connected directly to PLC inputs so
when activated are active the PLC will see a 22V signal (approx. - the exact switch
loss will depend on loading of the output).
To drive external loads (eg. relays), connect the relay coil positive supply to the
output common and the output line directly to one side of the relay coil. Connect the
other end of the relay coil to the negative supply. It is recommended that fly-back
diodes or transient suppressors be fitted across relay coils to limit switching noise.

Reference Manual Rev 3.23 Software Versions 3.xx
Page 15
3.10.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 (eg. 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 23 for more information.
WARNING
The opto-LINK head contains a strong magnet and care should be taken with
its proximity to electronic media (eg. credit cards, floppy disks, etc.) and/or
other electronic instrumentation.
Figure 13: opto-LINK Attachment

Reference Manual Rev 3.23 Software Versions 3.xx
Page 16
3.11.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.
Figure 14 illustrates an example of possible connections. Also shown are the
connecting cables restrained using cable ties fastened around the cable strain relief
anchors.
Figure 14: Cable Shield Connection
3.11.1. 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.
3.12.Regulatory Sealing Requirements
To comply with regulatory sealing requirements for each instrument, (ie. to ensure
instruments are not accidentally or deliberately tampered with), it is important that proper
sealing procedures be adhered to. Refer to Sealing page 60 for more information.
