Time Base, Total Conversion Factor
& Total Reset
The time base, total conversion factor, and total reset
menus are located in the
Program
menu.
The total and grand total have their own independent
settings. This means that one can be displaying the
value in gallons while the other displays in million
gallons, liters, m
3
, etc.
Time Base
The time base is the amount of time over which the
rate parameter should accrue. For example, if the rate
was ten and the time base was in minutes, then the
total would increase by ten every one minute.
Total & Grand Total Conversion
Factor
The total & grand total conversion factor is the
amount by which the rate is multiplied before it is
added to the total or grand total. For Example, if the
rate was ten per second and the total conversion
factor was 100, the total would increase by 1000
every second. This is useful, for instance, if you want
to show rate in gallons and total in thousands of
gallons.
Total & Grand Total Reset
The totals can be programmed for automatic or
manual reset. In the automatic reset mode, a
programmable time delay is available to reset the total
or grand total after the assigned preset is reached.
The totals can also be reset via the front panel button,
via a switch across the F4 terminal, digital inputs, or
via a Modbus command.
Non-Resettable Totalizer
The total and grand total can be password-protected
to prevent unauthorized resets. The grand total can
be programmed as a non-resettable total. See
Reset Password & Non-Resettable Total
on page
for details.
