TOTALIZER PARAMETERS (P622,P630,P633,P640-P642,P645)
If the
8 digit totalizer display
(LCD TOTAL), or a remote totalizer contact closure is
desired, alter the following parameters as required.
P622 (G) INFLOW / DISCHARGE ADJUST
This parameter selects the method used to calculate the volume pumped,
for "pumped total" Operation (P001 = 7).
values: 1 = inflow
* / pump cycle
When the pump is off, the HydroRanger plus estimates the
volume of inflow by recording the rate at which the liquid level
changes. When the pump is operating, the estimated inflow
volume is added to the pumped volume total, as in batch
processing. When the pump stops, the pumped volume of the
previous pump cycle is added to the total volume pumped in
the totalizer.
2 = inflow
* ignored
Inflow is assumed to be 0 while pumps are running.
3 = inflow
* / rate (preset)
Volume pumped is adjusted for inflow. Inflow rate is estimated
by assuming that the rate calculated (P708) just prior to the
start of the pump cycle remained constant during the pump
cycle. Inflow rate is averaged using rate filter (P704), rate
update time (P705) and rate update distance (P706) to control
how the average rate is calculated.
* or discharge
P623 PUMP TOTAL METHOD
This parameter determines the method used for updating the pumped
volume totalizer.
values: 1 = Volume pumped is calculated from the volume readings at the
start and end of the pump cycle. The result is compensated for
estimated inflow which is added to the total volume change
while pumps are running. Inflow rate is estimated as selected
by the inflow / discharge adjust (P622).
2 = Volume pumped is calculated from the pump rate (P182) for
each pump, and the running time of each pump. Pump rate is
recalculated on each pump cycle, based on the rate of change
of level or volume before and after each pump starts. Accuracy
of the totalizer when using this selection is entirely dependent
on the accuracy of the rate calculation, so the user must ensure
that appropriate settings are entered for pump rate time
(P181), start delay (P132). (preset)
