The LED display dominates the front panel. The operator will view the total and rate
on this display. In totalizing applications, six digits (up to 999,999) is often not ad-
equate. The installer has three options in this case, all available through program-
ming.
1. The installer can program the Eclipse to divide the total by 10 (display up to
999,999 tens of gallons).
2. The installer can divide by 100 (display up to 999,999 hundreds of gallons).
3. The installer can display a 10 digit total in the form of the low five digits and the
high five digits on successive screens.
The display will also be used by the installer for programming purposes.
The four input keys will be used primarily by the installer for programming purposes,
but the operator can use them also for changing the display screen from total to rate,
for example. The reset key is programmable. For the base unit, the reset key can
reset the total, or do nothing for the operator.
The program mode indicating LED lets the installer know that he is in the program
mode.
The totalizer base unit has a control input board installed that allows the installer to
wire external switches to it to reset the total and to lock out the program mode from
the operator. These inputs may also perform other functions if the relay option board
is installed.
A
batch control
is a counter that opens a valve to allow flow to start and counts out
a certain preset volume of liquid as entered by the operator. It then shuts off the valve
after the “batch” has been delivered. This is a closed-loop control system. There are
