Summing and Accumulator Mode Note
Using Code 319 Cut-off for Summing and Accumulator Modes:
When the owmeter is used in summing or accumulator mode, a ow cutoff may
be set for each summed valve controller or owmeter (up to 20 devices). This permits
compensation for differences in turbulence in different pipe sizes. The values entered
with Code 319 in the summing module should match the cutoff value set in each valve
controller or owmeter with the corresponding ID number.
Note: The default value from the factory for ow cutoff is 10 GPM for all IDs.
1. Enter program code 319.
Result: The display toggles between the ID number and the cutoff value for
that ID.
2. Press and release the MODE button to increase the ID to the next higher value.
Press and hold the MODE button to automatically step though subsequent ID
numbers.
The display alternates between the ID number and the cutoff value.
3. Press the TOTAL button and adjust the displayed ow cutoff rate:
The MODE button selects the digit to change. The digit will ash.
The TOTAL button changes the value of the ashing digit.
4. Press and hold the MODE button then press the TOTAL button, the next ID
is displayed.
5. When all cutoff values have been entered, press and hold the MODE button
and then press the TOTAL button to exit programming mode and return to
normal operation.
