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 9.6V, 12V or 24V batteries or a DC power source from 12V 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, 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 three isolated transistor outputs with status display and LEDs 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 28 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
The unit has been designed for high-pressure, high temperature (80°C) wash-down environments.
However long periods of focused pressure at a close range will damage the casing. Casing is
chemical resistant

Reference Manual V1.10 Software Versions 3.xx
Page 8 X300-621-110
3.5. 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 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
3.6. 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.
3.7. Load Cell Connection
3.7.1. 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 35.
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 30.

Reference Manual V1.10 Software Versions 3.xx
X300-621-110 Page 9
3.7.2. 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 30.
Figure 3: 4-Wire Connections
3.7.3. 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 30.
Figure 4: 6-Wire Connections
3.8. Auxiliary Connections
This section provides diagrams to illustrate the terminal connections.
