1.Introduction
1.1. Overview
This precision digital indicator uses the latest Sigma-Delta A/D technology to ensure
fast and accurate weight readings. The setup and calibration of the instrument are
digital, with a non-volatile security store for all setup parameters.
It may be operated from either a DC power source (12VDC to 24VDC) or AC power
(optional 110 –240 VAC). There is a soft power on/off function that retains memory
of its state. Once an instrument is turned on it will automatically start up again if the
external power is interrupted.
Optical communications is fitted standard and allows for a temporary isolated
communications link to be established with a PC. Software upgrades, the use of
computerised setup and calibration can then be done using a PC. Refer to Optical
Communications page 14 for more information.
Figure 1: Weight Indicator
The instrument provides zero, tare, gross/net, truck and print on the fixed function
keys and supports special functions (eg. printing, unit switching, etc.), via user
definable function key and external inputs. Operator functions (clock, report etc)
and editing functions are provided on the alpha/numeric key pad. 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.
The RS-232 communications port can be used for printer driving, connection to a
remote display or PC. The transmit only RS-485 communications port can be used
for remote displays. There is a built-in clock for date-stamping printed outputs.
The instrument can support different software applications depending on the
functionality required.

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.
Insert any accessory modules that are being used.
Use the drill hole template provided for hole locations.
Connect Power to indicator and press <POWER> key to turn the instrument On.
Refer to the Setup Menus section on page 5556 for information on configuring 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.
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
The panel mount template is supplied with the instrument. It shows the location of
the rectangular cut-out and the four mounting screws.
3.6. 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 wires with solder or to add crimp
ferrules to the wires, however, these techniques are compatible with the terminals.

Reference Manual Rev 1.12
Page 10 004R-646-112
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.
3.8. Load Cell Connection
3.8.1. Load Cell Signals and Scale Build
Very low output scale bases may be used but may induce some instability in the
weight readings when used with higher resolutions. Generally speaking, the higher
the output, or the lower the number of divisions, the greater the display stability and
accuracy.
The instrument can display the milli-Volt-per-Volt reading which can be used to
check scale base signal output levels. For more information, refer to Scale Test
Display page 5960.
The instrument may be connected for either 4-wire or 6–wire operation. Use 4-wire
when external SENSE connections are not available.
3.8.2. 4-Wire Connection
The minimum connectivity requirements are the connection of four wires (i.e. ±
Excitation and ± Signal). Internally the instrument has a precision analog switch
that can be used to connect the Sense+ and Sense–lines directly to the
Excitation+ and Excitation–lines.
Any addition to the load cell manufacturer's cable length using 4-wire connection is
only recommended for short cable runs. Where long additions to cable lengths are
needed, a 6-wire extension is required.
The BUILD: CABLE option must be set to 4-WIRE to allow for 4-wire connection.

Reference Manual Rev 1.12
004R-646-112 Page 11
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-WIRE to allow for true 6-wire
connection.

3.9.1. RS-232 Serial
Direct Personal Computer Link (RX, TX, GND)
Figure 5: RS-232 - Instrument to PC using COM Port (DB9)
Printer Connections (TX, DTR and GND)
Figure 6: RS-232 –Instrument to Printer (DB25)
Remote Display (TXD, GND)
Refer to documentation supplied with the Remote Display for connection
details. Connect RX on the Remote Display with TX on the instrument and
connect the RS232 GND signals together.
Ring Networks: Multiple Instruments to PC (RXD, TXD, GND)
Instruments with software revision V2.31+ can be configured in a Ring Network
via a M42xx module (software revision 1.01+). This feature is not available on
the inbuilt serial port. This also requires an enhancement in the PC software.
The Short Ring Network layout (Figure 7) 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,
which uses a separate return path from the ‘Last Instrument’ to the PC.
For DB25 connections at the PC connector, refer to Figure 6.

Reference Manual Rev 1.12
004R-646-112 Page 13
When operating in a Ring Network, the Instruments must have:
same serial port options, i.e., baud, parity, data bits, stop bits;
unique addresses.

3.9.2. RS-485 Serial
Remote Display (TA, TB)
RS485 is recommended for communicating over distances longer than a few
metres. Connect TA to RA and TB to RB on the remote display.
3.10. Optical Communications
A temporary infrared communications link can be established between the
instrument and a PC using an optional cable. This connection can be used to
transfer setup and calibration information from a PC or to download software
upgrades.
The PC end of the cable is a standard female DB9 RS232 connector. The
instrument end of the cable attaches to the left side of the instrument display.
WARNING
The optical coupling head contains a strong magnet and should not be placed
near any magnetic storage media (eg. credit cards, floppy disks etc.)

3.11. Connecting Shields
To obtain full EMC or for RFI immunity, cable shields MUST be connected and
the earth lug on the rear of the instrument must be grounded.
Figure 10 illustrates an example of possible connections. Also shown are the
connecting cables restrained using cable ties fastened by screws into the rear of the
unit.

Reference Manual Rev 1.12
Page 16 004R-646-112
Figure 10: 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 to the connectors
is very important. The earth lug of the instrument must be separately connected to
ground potential via a reliable link.
The AC power module directly connects the earth lug to the Earth Pin on the power
supply. In installations where earth is available on the power cable, instrument
earthing can be done with this connection.
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 Section 3.9.1 on page 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, (i.e. to ensure
instruments are not accidentally or deliberately tampered with), it is important that

Reference Manual Rev 1.12
004R-646-112 Page 17
proper sealing procedures be adhered to. Refer to Trade Label page 113114, Lead
Seals page 113114, Destructible Sticker Seals page 113114 and Electronic Seal
page 113114 sections for more information.
3.13. Accessory Module connection
Up to 4 accessory modules can be plugged into the rear of the instrument. There
are many types of modules which can be used. These modules provide additional
features such as:
power supply options, e.g. mains power or batteries
communications ports, e.g. Ethernet or RS485 networking
digital inputs and digital outputs, e.g. external buttons or setpoint outputs
expanded memory, e.g. DSD functionality.
Caution: Instrument should be switched off before connecting or disconnecting
accessory modules.
Each module will come with a manual which explains the features, installation and
use of the module.
After connection, the module needs to be configured using the instrument setup
menus. All hardware test functions and hardware options (such as serial baud
rates or digital input debouncing) are in the H.WARE (hardware) menu described in
section 0 page 5960. Module resources (such as digital inputs or serial ports) are
assigned in specific function menus. For example, the output used by a particular
setpoint is set in the setpoint menu.
A summary of the module resource usage is available in the instrument setup
menus. See ALLOC (Allocation Report) described in section 12.2.1 page 5960.
Note: Power supply options can only be connected in the left position. Other
modules can be connected in any position.
