4.0 WARNINGS
4.1 General
• 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.
• 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.
4.2 Configuration Issues
• Configuration and calibration can be performed from the front panel, using digital setup. When Full Setup is
used, all menu items are accessible and care must be taken to ensure no accidental changes are made to
calibration and trade settings.
• Enter a passcode to prevent unauthorized or accidental tampering. If the passcode is lost, GSE Scale Systems
should be contacted for further advice.
5.0 INSTALLATION
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 drill hole template provided for hole locations.
• Connect Power to indicator and press <POWER> key to turn the instrument On.
• Refer to the Instrument Setup section page 15 for information on configuring and calibrating the instrument.
• To turn instrument Off press and hold <POWER> key for three seconds (until display blanks).
5.1 Electrical Safety
• For your protection all 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.
5.2 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 drilling template supplied with the indicator allows for front or rear
machining of the panel.
5.3 Special Function Key
• The Special Function Key on the instrument ships as a blank key.
• If any of the special functions are to be used on the indicator it is important that the matching function key
overlay sticker (supplied) is applied to the keypad.
• Ensure keypad is clean and dry before affixing sticker.
CF 146

V- Rev. 1.0 - 003R-620-100
5.4 GSE-LINK
The optional GSE-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.
• Attach the GSE-LINK cable to the PC using the DB9 connector.
• Attach the GSE-LINK head to the left side of the instrument display using
the permanent magnet located within the head of the GSE-LINK.
WARNING: The GSE-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.
5.4.1 GSE-LINK Activation
A long press of the <GROSS/NET> key will toggle the GSE-LINK infrared communications On/Off.
When the GSE-LINK has been enabled the following will occur:
• The instrument briefly displays the prompt rin-L.
• The editing annunciators (i.e. GRP, ITM, etc.) will flash for up to five minutes while the instrument searches for
activity. During this period, the instrument also disables the RS-232 communications.
• Activity Located: If the instrument is successful in locating activity, the editing annunciators will continue to
flash during the entire period of communications.
• No Activity Located: If the instrument fails to locate activity, the GSE-LINK will be disabled and the editing
annunciators will stop flashing. The instrument will also revert back to the normal RS-232 communications (i.e.
the SERIAL:TYPE setting will be re-activated).
6.0 CONNECTIONS
6.1 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.
6.2 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 AC wall transformer as long as there is sufficient capacity
to drive both it and the load cells.
CF 146

V- Rev. 1.0 - 003R-620-100
6.3 Load Cell Connection
The instrument may be connected for either 4-wire or 6-wire operation. For more information, refer to
BUILD:CABLE setting section 7.6.
6.3.1 4-Wire Connection
The minimum connectivity requirements are the connection of four wires (i.e. Excitation + and – along with Signal +
and –).
The BUILD:CABLE option must be set to 4 to allow for 4-wire connection.
6.3.2 6-Wire Connection
The excitation and signal lines are connected the same as for a 4-wire installation.
The BUILD:CABLE option must be set to 6 (the default) to allow for 6-wire connection.
6.4 Auxiliary Connections
This section provides diagrams to illustrate the terminal connections.
6.4.1 Direct Personal Computer Link (RXD, TXD, GND)
RS-232 - Instrument to PC using COM Port (DB9)

6.4.2 Printer Connections (RXD/TXD, GND and DTR)
RS-232 – Instrument to Printer (DB25)
6.4.3 Remote Display (TXD, GND)
• Connect TXD to RXD and GND to GND on the remote display.
6.4.4 Remote Input
• The indicator requires a voltage free contact between TXD and RXD to enable the remote input (i.e.
SPEC:REM.FN).
Note: The remote input will not function when in setup or when using the GSE-LINK.
WARNING
The remote input is a
voltage free contact (e.g.
button, mechanical
relay). Connection of
any active circuitry may
damage the instrument.
6.4.5 Outputs
• Output drivers for the instrument are isolated open emitter transistor drives that are capable of driving up to a
total of 300mA.
CF 146
5
V- Rev. 1.0 - 003R-620-100
• 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 the outputs are active the PLC will see a 24V signal.
• 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.
Outputs to Drive Relay
Outputs to Drive PLC
6.5 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.
This figure shows the connecting cables restrained using cable ties fastened around the cable strain relief anchors.
CF 146
6
V- Rev. 1.0 - 003R-620-100
6.5.1 Cable Shield Connection and Earthing
• Care should be taken when connecting shields to maximize EMC or RFI immunity and minimize earth loops
and crosstalk (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.
• 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.
6.6 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.
6.6.1 Sealing
Affix sealing stickers to the rear of the instrument, over one or more screws in the locations indicated.
Also affix a sealing sticker over the load cell cable where the cable-tie strain relief is attached, as indicated.
Affix stickers in the locations indicated.
7.0 INSTRUMENT SETUP
7.1 Calibration Counter
The built-in calibration counter(s) monitor the number of times trade critical settings are altered. Refer to Trade

9.0 WARRANTY REPAIR POLICY
Limited Warranty on Products
Any Cooper Instruments product which, under normal operating conditions, proves defective in material or in
workmanship within one year of the date of shipment by Cooper will be repaired or replaced free of charge provided
that a return material authorization is obtained from Cooper and the defective product is sent, transportation

maintained, and operated within the limits of rated and normal usage. Replacement or repaired product will be
shipped F.O.B. from our plant. The terms of this warranty do not extend to any product or part thereof which, under
normal usage, has an inherently shorter useful life than one year. The replacement warranty detailed here is the
buyer’s exclusive remedy, and will satisfy all obligations of Cooper whether based on contract, negligence, or
otherwise. Cooper is not responsible for any incidental or consequential loss or damage which might result from a
failure of any and all other warranties, express or implied, including implied warranty of merchantability or fitness for
particular purpose. Any unauthorized disassembly or attempt to repair voids this warranty.

return the original calibration data with the unit.
Repair Warranty
All repairs of Cooper products are warranted for a period of 90 days from date of shipment. This warranty applies
only to those items that were found defective and repaired; it does not apply to products in which no defect was
found and returned as is or merely recalibrated. It may be possible for out-of-warranty products to be returned to
the exact original specifications or dimensions.
* Technical description of the defect: In order to properly repair a product, it is absolutely necessary for Cooper to
