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 16 for more information.
The instrument comes with five different firmware types (K342, K344, K346, K354, and K356).
FACTRY.APP.ID can be used to select desired firmware. Then licence code should be entered using
FACTRY.L.CODE. Refer FACTRY menu page 41 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.
(NVRAM only supported in the K35* models)
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 section page 31 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 V1.19 Software Versions 4.xx
003R-682-119Page 9
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 TEST (Special Test Functions) 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 34.

Reference Manual V1.19 Software Versions 4.xx
Page 10 003R-682-119
3.8.2. 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 (4-Wire
or 6-Wire) page 34.
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 34.

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 (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 V1.19 Software Versions 4.xx
003R-682-119Page 15
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 (i.e. OUT1 and OUT2)
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 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 (e.g. 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.

Page 16 003R-682-119
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 (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 23 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.

Reference Manual V1.19 Software Versions 4.xx
003R-682-119Page 17
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.

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 12 and 13.
•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 proper sealing procedures be
adhered to. Refer to Appendix - Trade Sealing page 63 for more information.
