ON Setpoint Pump 1 (2.7.1.6.)
(Page 186)
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.
ON Setpoint Pump 2 (2.7.1.8.)
(Page 186)
1.2 m Sets the level at which pump 2 turns on.
OFF Setpoint Pump 1 (2.7.1.7.)
(Page 186)
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.
OFF Setpoint Pump 2 (2.7.1.9.)
(Page 186)
0.3 m Sets the level at which pump 2 turns off.
Totalizer Decimal Position
(2.7.3.2.) (Page 195)
2 DIGITS Sets the totalizer display to 2 digits.
Totalizer Multiplier (2.7.3.3.)
(Page 195)
1000 Actual volume is divided by 1000, prior to dis-
play on LCD.
Inflow/Discharge Adjust
(2.7.3.4.) (Page 195)
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.
1. Display vessel volume on the LCD (set parameter Sensor Mode (2.1.2.) (Page 168) to
VOLUME).
2. Toggle to SV on LCD to display current level (set parameter Sensor Mode Secondary
(2.1.4.) (Page 170) to LEVEL).
3. See Running Totalizer (2.7.3.1.) (Page 194) to view pumped volume.
