Each tank has its own set of alarms, with each set of 6 having a
common output to operate lights, horns, engine shutdowns, or
valves. The dispense alarm can be programmed from the front
panel using the push buttons; it is used to accurately dispense
the correct amount of product by sounding a horn or shutting a
valve when the amount to be dispensed has been reached. The
rising level alarm activates if a tank level not being viewed rises
more than a few inches to alert the operator that the wrong tank
is being filled. The overfill warning alarm is programmed into the
gauge with the 817 programmer, and is used to warn the operator
that the tank being filled has reached its maximum level. The
overfill shutdown alarm is also programmed into the gauge with
the 817 programmer, and functions as an emergency shutdown to
prevent the tank from being overfilled and causing a spill.
See Chapter 5 for details of alarm operation.
WARNING: The use of alarm points is entirely at the owner's
risk due to the nature of connecting external horns or lights,
the reliability of external horns or lights, and the requirement
for truck power to operate them.
Installation of the gauge is straight forward, consisting of mounting
one sender bar in each of the tanks, mounting the display at a
convenient location, connecting the sender bars to the display
with the provided fibre optic cable, and wiring the display to truck
power and the various alarm lights, horns, shutdowns, or valves.
Programming the calibrations and alarm points into the display
completes the installation. Any of the components can be easily
replaced for servicing. Chapter 10 describes the installation in
detail.
