the gauge will recognize this and wait for another complete
transmission before going to the next sender.
6. During dispensing, it is important for the gauge to focus on
the viewed tank so that it can respond as quickly as possible
when the dispensing amount has been reached. This is why
scanning is not done during dispensing.
Select a tank to view:
1. The lower right display shows the tank number currently
selected. To select another tank, press and hold the
corresponding tank button until the display changes to the
new tank number.
2. The tank buttons are illuminated by amber/orange LEDs for
night visibility. The selected tank will have the LED brightly
illuminated.
3. If the 12 volt power to the gauge is not active, then the LEDs
will not work but the tank buttons and the tank volume
information will still function.
Check the software version of the main processor:
1. Either unplug the fibre optic cable from the tank being viewed,
or disconnect the ribbon cable between the display face and
the base circuit board. The display must be showing "no L" in
order to check the version.
2. Press and hold the UP and HORN buttons on the front of the
display. The display will show "rX.XX code", where X.XX will be
a number like 5.18, which is the software code version of the
main processor.
3. Release the buttons to return to normal operation. Reconnect
the fibre or ribbon cable.
4. See the section on Serial Interface Commands to find the
software version of the remote communications processor.
How to connect and program the PTO input:
1. The PTO input senses the state of the truck PTO in order
to know when loading or dispensing is occurring. Alarm
operation is affected by PTO status, see the alarm section for
full details.
