General Description
The FUSION Series of displays accept industrial sensors to allow various
physical measurements to be made, such a weight, temperature, pressure,
humidity etc. Different models are available for different sensor types.
The main function of the FUSION series is to give a large numeric readout of
the variable being monitored. You can choose from various digit sizes and
formats. Most models include an excitation power output, to power the sensor
directly.
Optional output modules are also available, to give alarm relay outputs, analogue
output or digital communications, or any combination of these options.
Displays are programmed using front panel pushbuttons. The buttons may be
locked with a switch. The buttons may also be wired remotely, so that you can
make your settings from ground level.
These displays have two power supply options : 100-240 VAC or 11-30VDC
These units must be installed fully assembled, and must be installed according
to local electrical installation rules. When properly installed, with glands on the
lower surface, they provide ingress protection to IP65 / NMA4X
Safety
Obey all safety warnings in this manual, and install the display according to
local wiring and installation regulations. Failure to follow these guidelines may
cause damage to the display, connected equipment, or may be harmful to
personnel.
Any moving mechanical device controlled by this equipment must have suitable
access guards to prevent injury to personnel if the meter should fail.
!
Caution: There is a risk of electrical
shock if this instrument is not properly installed
Caution: Risk of danger: Read the whole
manual before you install this meter

Mounting and Installation
Install your Fusion display according to local electrical regulations.
Mount it away from moving machinery, to minimise the chance of damage, and
keep away from sources of heat, plastics solvents and electrical and magnetic
noise, such as welding equipment, arc lighting, inductive machines etc.
The screws on the back of the display are necessary for sealing - do not omit
any screws.
Do not overtighten screws - it is sufficient to finger-tighten them. In no
circumstance use an electric screwdriver to remove or fit screws, or you will
damage the case threads and sealing will be impaired.
Power cables and alarm relay cables should be routed seaparately to input
signal, logic signal, serial data and analogue output cabling, to minimise the
chances of electrical interference.

8
Only open the case when power has been removed.
This display uses internal detachable screw terminal connectors. Refer to the
wiring diagram on the following page for the correct positioning of each wire.
Each cable is fed through a compression gland for sealing. All glands must be
sealed, unused glands must be plugged.
The conductors you use must be suitable for the meter’s temperature, current
and voltage rating, which is broadly described as follows:-
Cable Temperature Rating
All cables must be rated for operation up to 90C continuous.
Cable gauge
The connectors on this instrument can accept conductors up to 1.5mm2c.s.a.
The minimum cross sectional area shall be 0.5mm2
Cable insulation voltage rating
Cables shall have an insulation voltage rating of at least 380V continuous.
Wire preparation:
We recommend multi-strand wire, because it withstands vibration better than
single strand cable. Pull the wire firmly after you make the connection to confirm
it is tight.
Use screened cable for all signal and control wiring and connect the screen to
earth at the destination end only. Route signal cabling away from power cabling
and relay switching cabling, to avoid electrical noise interference.
Use a single, circular cable through each gland, diameter 4.5 to 6.5mm

Brightness Adjustment
In normal operation, you can select from one of 8 brightness levels, to suit your local lighting
conditions, or to match the brightness of several meters which may be from different batches
or ages.
Press for 3 seconds, then press the down or up button to decrease or increase the
brightness.
Press OK when set.
Your chosen brightness level will be saved in memory, so that the meter will return to the
chosen brightness after power-off.
Lockout notes: Cal Lock switch = ON when changing.
Drift cancellation (Not on INT2-C, INT2-S)
If your meter will normally be showing 0, for example a platform scale, you can set the meter
to continually cancel any long term drift. To do this, set Drf. 1. to remove this feature, select
Drf.0
This only operates at and around zero reading.
The meter will compares readings to previous ones every 30 seconds, and if the value has
changed by a small amount, the meter will aoutomatically re-zero. The maximum movement in
a 30 second period is 8 counts of the least-significant digit. Any more than that, we assume
the change has been a valid process movement, so leave the change unaltered.

Filter settings
You can use the filter to improve display stability. This is useful if your signal is unstable. Bigger
time constants give more stability but slower response.
The Time constant of this digital filter is very similar to the time constant of an RC filter where
T=RC . The time constant is the time it takes for the display to reach 63 % of its final reading
value, after a step change on the input.
You will see that if you select a 1 second filter time, it will take several seconds for the meter to
reach its final value.
To give improved response to large step changes, we can momentarily cancel the filter action
with the ‘Filter Jump’ feature
How does the Filter Jump feature work?
First, make a note of the range you calibrated your meter over (not the full dynamic range of the
meter, just the the difference between the maximum and minimum display values you set, in
either direct or theoretical calibration) Let’s assume you calibrated the meter for a 250 range.
If you set the filter jump percentage to 25%, any sudden change in input of less than 25% of 250
will be included in the averaging calculation.
However, a jump of greater than 25% will cause the filter to be ignored and the meter will
immediately jump to that new value.
If you set a jump of 0%, filtering will always be overridden (never any filtering)
If you set a jump of 99%, filtering will always be present, so long as the input signal doesn’t jump
more than 99% of the calibrated range.

Calibration Methods - introduction
Calibration lockout switch must be OFF to view
and/or change calibration.
Press Set1 and Set2 buttons at the same time...
There are two ways you can calibrate your display, and each way can be done with 2 points
only, or up to 10 linearisation points.
A. Direct connection of real-time low and high input signal levels, which you
scale the display against. (Zero and Span)
B. Theoretical scaling, where you use the keyboard to enter expected zero and
full scale sensor signals, and the measurement amounts these relate to .
After a couple of seconds,
display shows...
Press UP or DOWN arrow to change Press UP or DOWN arrow to change
Press OK to choose. Press OK to choose.
Examples of Theoretical Calibration...
1. If you do not yet have your sensor, but know what
its published calibration settings are.
For example, you plan to use a pressure sensor,
which will give 0-20mV for 0-250 kg. You can
enter the input range of 0-20mV and the
measurement range of 0-250.
2. If you are a distributor, supplying adisplay to
an end user who will be buying his sensor from
another source. He has told you on his order what
he would like the scaling to be.
Shortly after CAL.SrC appears, the
display will change to show either dIrECt
or tHEor as below.
When you have chosen the Calibration type, it will be saved in your display’s memory, so you
will not need to repeat the procedure.
You may now calibrate your display using your preferred method, on the following pages. ..
Examples of Direct Calibration...
1. If you want to calibrate a weighing system by
loading it with known calibration weights.
2. If you want to calibrate a straight-sided tank
gauging system by filling the tank with a known
amount of liquid.
3. If you are performing a calibration check against
a calibration reference, such as humidity cells, pH
buffers etc.

Direct Calibration, no linearisation
Set your calibration method to DIRECT - see previous page.
Assume we want to calibrate a weighing platform, rated at 250kg. We have a 200kg calibration
weight. (Use at least 60% rated load for calibration. 100% ideally)
First, calibrate the full scale (SPAN) reading. We do SPAN first, because in the SPAN procedure we
can set the decimal point position of our measurement, to set resolution.
SPAN Calibration . Apply your calibration load and press the Set2 button for 3 seconds.
Display will show ‘direct’ , ‘set HI’ . Press OK. You will see that one digit is brighter than the others.
You can edit the value of a brightened digit with the UP/DOWN buttons.
You can brighten other digits with the DIGIT button.
Go through each digit in turn, to set the desired value of your calibration load.
Press OK when done.
To set the decimal point position, press the Set2 button for 3 seconds whilst in the numeric
setting stage . You’ll see all decimal points light, with one brighter than the rest. Use UP or DOWN
buttons to move the brightest decimal point and press OK when in the desired position.
ZERO Calibration. Remove your load and press the Set1 button for 3 seconds.
Display will show ‘direct’ , ‘set LO’ . Press OK. You will see that one digit is brighter than the others.
You can edit the value of a brightened digit with the UP/DOWN buttons.
You can brighten other digits with the DIGIT button.
Go through each digit in turn, to set all digits to 0. Press OK when done.

Theoretical Cal., no linearisation - page 1
Set your calibration method to THEORETICAL - see previous pages
As an example, let us assume we want to calibrate the display for a pressure sensor input.
Let us also assume that we know from the calibration sheet which came with the pressure
sensor, that it has an output of 0-20mV and a rated capacity of 0 to 50 kg
.
We need to enter these figures into the display...
Start with the full scale SPAN setting...
Press the Set2 button for around 3 seconds.
The display will briefly show theor, to confirm that we
are in the theoretical setup mode.
Choose with the up or down arrows and press OK.
Set to highest input signal level which was
20mA, according to the sensor calibration
sheet in our example.
You can change the value of the brightest
digit with the UP or DOWN buttons.
Brighten other digits with the DIGIT button.
Press OK when done...
In HI will appear briefly, followed by a numeric
value, which you can set...
The numeric value will need to be the High
input signal level ...

rd HI will appear briefly, followed by a
numeric value, which you can set...
The numeric value will need to be the High
display reading value ...
Set to highest reading value, which was 50
according to the sensor calibration sheet in
our example.
You can change the value of the brightest
digit with the UP or DOWN buttons.
Brighten other digits with the DIGIT button.
Press OK when done...
You can change the position of the decimal point,
relating to rd HI (and rd LO)
This may be useful if you want to increase the
resolution of the display.
The resolution affects several of the display’s
important functions, such as ....
...the resolution of the analogue output signal
...the resolution of your alarm relay action.
...the resolution of the serial data output value.
As an example, assume you have a sensor with 10
tonne capacity.
If you scale the display for 0 to 10, the resolution will
only be 1 part in 10
Your analogue output will change in 10% steps.Your
precision of alarm setting would be to within 1 tonne.
The resolution of serial data would be within 1 tonne.
However, if you include a decimal point you could
control the resolution, as in these examples :-
0-10.0 which gives 1% resolution
0-10.00 which gives 0.1% resolution
0-10.000 which gives 0.01% resolution
You cannot get more resolution than 1 part in 60000.
This is the limit of resolution in the A/D converter.
Note: If you change the decimal point position, you
must reset the rdLO and rdHI values also.
Next .... how to set the theoretical ZERO calibration...
Theoretical cal., no linearisation - page 2
To change decimal point position, press the Set2
button for around 3 seconds while you’re in the rdHI
