Totalizing pumped volume
Available only on LUT430 (Pump and Flow model), and LUT440 (OCM model).
Prerequisite: The volume of the vessel must be known.
1.
Display vessel volume on the LCD (set parameter
to VOLUME).
2.
Toggle to SV on LCD to display current level (set parameter
to LEVEL).
3.
See
to view pumped volume.
Setting a pump to run-on
This functionality is used to reduce sludge and sediment from building up at the bottom of
a wet well, thereby reducing maintenance. This is achieved by running the pumps below
the normal OFF setpoint and requires you to set a run-on duration and interval to control
this event.
Parameter
Sample
Value
Description
LINEAR Vessel shape is linear (flat bottom)
17.6
Max volume is 17.6m
3
or 17,600 liters.
or
ADA
Sets the control algorithm used to trip the
pump relay to ALTERNATE DUTY ASSIST.
1.0 m
Sets the level at which pump 1 turns on. The
first cycle will use this setpoint. Subsequent
cycles rotate the setpoint among the
pumps.
1.2 m
Sets the level at which pump 2 turns on.
0.2 m
Sets the level at which pump 1 turns off. The
first cycle will use this setpoint. Subsequent
cycles rotate the setpoint among the
pumps.
0.3 m
Sets the level at which pump 2 turns off.
2.7.3.2. Totalizer Decimal
Position
2 DIGITS Sets the totalizer display to 2 digits.
1000
Actual volume is divided by 1000, prior to
display on LCD.
2.7.3.4. Inflow/Discharge
Adjust
RATE
ESTIMATE
The inflow rate measured just prior to the
start of the pump cycle is used to estimate
the inflow for the duration of the cycle.
