1.Introduction
Thisinstrument isaprecision digitalindicator usingthe latest Sigma-Deltaanalogue todigital
conversion technologytoensurefast and accurateweight readings.
Figure1: Weight Indicator
The setup and calibration ofthe instrument aredigital, withanon-volatilesecuritystorefor all setup
parameters.
The instrument maybe operated from 4.8V, 7.2V, 9.6V, 12Vor 24Vbatteries or aDC power source
from 7Vto24V. Thereisasoft power on/off function that retains memoryofthe indicator’sstate.
Once an instrument isturned on it will automaticallystart up againifthe externalpower is
interrupted.
The instrument isfitted withopto-LINK communications as standard. Thisallowsatemporary
isolated communications linktobe established withaPC usingan opto-LINK cable, which enables
softwareupgrades and the use ofcomputerised setup and calibration viathe Viewer software.
Refer toopto-LINK (Optional) page16 for moreinformation.
1.1.Overview
Thisinstrument provides ZERO and TARE functionalityas well as moresetup options (eg.
serialand setpoints) and printingfunctionality.

3. Installation
3.1.Introduction
The followingsteps arerequired toset up the indicator.
•Inspect indicator toensuregood condition.
•Use connection diagramstowireup load cell, power and auxiliarycables as required.
•Use the panelmount templateprovided for holelocations.
•Connect Power toindicator and press <POWER> keytoturnthe instrument on.
•Refer tothe Setup section page30 for information on configuringand calibratingthe
instrument.
•Toturninstrument off press and hold <POWER> keyfor three seconds (until display
blanks).
3.2.General Warnings
•Indicator not tobe subject toshock, excessivevibration or extremes oftemperature
(beforeor after installation).
•Inputsareprotected against electricalinterference, but excessivelevelsofelectro-
magneticradiation and RFI mayaffect the accuracyand stability.
•The instrument shouldbe installed awayfrom anysources ofexcessiveelectricalnoise.
•The load cell cableisparticularlysensitivetoelectricalnoise and shouldbe located well
awayfrom anypower or switchingcircuits.
•For full EMCor for RFI immunity, termination ofcableshields and correct earthingofthe
instrument isessential.
•Indicator and load cell cablearesensitivetoexcessiveelectricalnoise. Install well away
from anypower or switchingcircuits.
3.3.Electrical Safety
•For your protection all mains electricalhardwaremust be rated for environmental
conditions ofuse.
•Pluggableequipment must be installed near an easilyaccessiblepower socket outlet.
•Toavoidthe possibilityofelectricshockor damagetothe instrument, alwaysswitch off
or isolatethe instrument from the power supplybeforemaintenance iscarried out.
3.4.Cleaning
•Tomaintainthe instrument, never use harsh abrasivecleanersor solvents. Wipe the
instrument withasoft cloth slightly dampened withwarm soapywater.
3.5.Panel Mount Template
Use the panelmount templatefor drill holelocations. The templateindicates positions for the
two4mm mountingscrewsthroughthe panel. Also displayed on the templateisthe position
ofthe rectangular holethat shouldbe cut toallowfor the connection ofcables. The template
supplied withthe indicator allowsfor front or rear machiningofthe panel.

Reference Manual V1.00 SoftwareVersions3.xx
003R-677-210 Page9
3.6.CableConnections
All cableconnections aremade tothe rear ofthe instrument usingscrewless terminals.
Wires must be stripped ofinsulation byat least 10mm. Toinstall, depress the orangelever
beside the terminalrequired and push wireintothe hole. Release the lever and pull gentlyon
the wiretoensureit issecurelytrapped inthe terminal. It isnot necessarytotinthe ends of
the wirewithsolder or toadd crimpferrules tothe wires, however, these techniques arealso
compatiblewiththe terminalsand mayultimatelymakefor aneater job.
Figure2: CableConnections
3.7.DC Power(DC PWR+ , DC PWR–)
The DC supplyneed not be regulated, provided that it isfree ofexcessiveelectricalnoise and
sudden transients. The instrument can be operated from ahighqualityplug-packas longas
thereissufficient capacitytodrivebothit and the load cells.
Ifan optionalbatterypackisfitted, then the supplied chargingsystem must be used.
3.8.LoadCell Connection
3.8.1.LoadCell Signalsand ScaleBuild
Verylowoutput scalebases maybe used but mayresult insomeinstabilityinthe weight
readingswhen used at higher resolutions. Generallyspeaking, the higher the load cell output,
or the lower the number ofdivisions, the greater the displaystabilityand accuracy.
The instrument can displaythe millivolt-per-volt readingthat can be used tocheckscalebase
signaloutput levels. For moreinformation, refer toTEST(SpecialTest Functions) page37.
The instrument maybe connected for either 4-wireor 6–wireoperation. Tocorrespond withthe
actualcablinginstallation the instrument must be configured insetup tothe correct setting. For
moreinformation, refer to CABLE
(4-Wireor6-Wire) ⊗page32.

Reference Manual V1.00 SoftwareVersions3.xx
Page10 003R-677-210
3.8.2.4-WireConnection
The minimum connectivityrequirementsarethe connection offour wires (ie. Excitation + and
–alongwithSignal+ and –). Internallythe instrument has aprecision analogue switch that
connectsthe Sense + and –lines directlytothe Excitation + and –lines when 4-wiremode is
selected.
A4-wireconnection isonlysuitablefor short cableruns. Wherelongcablelengths are
needed, a6-wireextension isrequired tomaintainaccuracy.
The BUILD:CABLEoption must be set to 4 toallowfor 4-wireconnection. Refer to CABLE
(4-Wireor6-Wire) ⊗page32.
Figure3: 4-WireConnections
3.8.3.6-WireConnection
The excitation and signallines areconnected the sameas for a4-wireinstallation. The extra
twowires (Sense + and –) shouldbe connected tothe Excitation + and –lines as close as
possibletothe load cell itself. Typicallythese connections aremade inaload cell termination
box.
The BUILD:CABLEoption must be set to 6 (the default) toallowfor 6-wireconnection. Refer to
CABLE
(4-Wireor6-Wire) ⊗page32.
Figure4: 6-WireConnections
