When the unit powers on it displays the initial product identity screen for a few seconds and
then displays the Tank Display.
3.1 SCREEN / KEYPAD BRIGHTNESS CONTROL
The unit has ve tactile buttons along its lower face and pressing any of the rst four buttons
will bring up the button bar which identies the current button function. Pressing the required
button will then execute the function chosen and the button bar will disappear a few seconds
later leaving the whole screen displaying the required data.
The fth button allows the user to vary the screen brightness and keyboard illumination which
is shown below.
Pressing the rst two buttons varies the screen brightness and the next two buttons vary the
key backlights. When the desired levels have been set press the fth button to clear the display
brightness control.
3.2 TANK DISPLAY
The rst display screen is Page 0 of the tank levels / volumes display and this can always be
selected by pressing the rst or most left hand button on the unit.
An example of this display is shown on the next page.

6 of 30
Here we can see that the Tank Display screen is split into 4 quadrants so the user can monitor
4 tanks at once. The centre of the screen at the junction of the four quadrants displays the
Quadrant Page Number which in the above case is Page 0. The display has eight different pages
available which are selected by repeatedly pressing the “TANK” button which will progressively
step through each display page. This allows the user to display up to eight pages each of four
tanks to a total of thirty two tanks.
Each quadrant of the above display contains the following information:
1. In the top centre of the quadrant is the user assignable tank name. When the
unit is delivered each tank type has a generic tank type name that can be set to
any name the user wishes to help identify the tank. See section 4.2.3 later in this
manual for information on how to do this.
2. At the top left hand side of the quadrant is the Tank Number or Instance which
needs to correspond with the number set on the tank sender Address or Instance
switch.
3. At the top right hand side of the quadrant (not shown above) there may be a
small alarm bell symbol which indicates that this tank level is outside it’s
alarm level limits and the alarm has been notied and acknowledged by the user.
See the section on Tank Level Alarms in section 4.2.6
4. In the centre of the quadrant is a gauge showing the tank level / volume per
centage and a pictogram of the tank type.
5. In the lower part of the quadrant is a digital display panel. This panel will show
the tank level as a percentage, ie 45%, if the total tank volume is not being trans
mitted by the sender. If the sender is transmitting the total tank volume as well as
the tank level then the digital display panel will show the remaining uid
volume in either Litres, US Gallons or Imperial Gallons as chosen by the
user conguration in section 4.2.2 below.
6. The gauge arc will display partially in red (not shown) if either the low or high
level alarm has been set to a suitable value and the alarm has been enabled. See
section 4.2.6 later in this manual for information on how to do this.
The user can select which tanks are displayed on each quadrant of each Quadrant Page by
pressing the “TANK” button to bring up the button bar then pressing the “RIGHT ARROW”
button which will alter the buttons to allow each quadrant to be changed.

7 of 30
Pressing the rst button the top left hand quadrant will change to display each of the different
tank sender levels being received and then a blank page in case the user does not wish to
display any tank in a given quadrant. Then by pressing the “BACK ARROW” button that selection
will be remembered and the display will revert to the normal tank display.
This can be repeated for each quadrant on each Quadrant Page giving the user the opportunity
to tailor the tank displays exactly as they wish.
3.3 BATTERY / DC SOURCE SUPPLY
By pressing the “BATT” button the display will show information about the rst two battery or
DC sources as shown below.
Repeated pressing of the “BATT” button will display the next two batteries or DC sources to a
total of 16 sources. Each side of the display contains the following information:
1. In the top centre of each side is the Battery or DC Source user assignable name. When the

8 of 30
unit is delivered each battery or DC source has a generic name that can be set to any
name the user wishes to help identify the Battery or DC source. See section 4.2.4 later in
this manual for information on how to do this.
2. At the top left hand side of each side there is a Battery or DC Source Instance number
which needs to correspond with the Instance of the DC Monitor supplying the data to the
network.
3. The top display gauge is the current charging or being drawn from the battery / DC
source. This gauge scale has our “Autoranging” feature so that if the current exceeds 60
amps the gauge scales will automatically autorange to a higher scale. This gauge also
includes a digital display panel showing the current ow numerically.
4. The second display gauge shows the voltage of the battery or DC source, also with
autoranging between 12 and 24 volt systems and a digital display panel.
5. At the bottom of each side is a battery temperature gauge.
3.4 GENERATOR / AC SOURCE SUPPLY
By pressing the “ACPWR” button the display will show information about the rst two AC
Generators or AC Busses or Shore Power as shown below.
Repeated pressing of the “ACPWR” button will display the next two AC sources to a total of 16
sources.
Each side of the display contains the following information:
1. In the top centre of each side is the AC Source user assignable name. When the unit is
delivered each AC source has a generic name that can be set to any name the user wishes
to help identify the AC source. See section 4.2.5 later in this manual for information on
how to do this.
2. At the top left hand side of each side there is an AC Source Instance
number which needs to correspond with the Instance of the AC Monitor supplying the data
to the network.
3. The top display gauge is the current being drawn from the AC source. This gauge also
includes a digital display panel showing the current ow numerically.
4. The second display gauge shows the voltage of the AC source, also with autoranging
between 110 and 240 volt systems, and a digital display panel.
5. At the bottom of each side is an AC Source frequency gauge.
