Pump control reference
B
This device has the pump control strategies to suit nearly any water/ wastewater application.
This section details these strategies for engineers requiring indepth knowledge of the system
and how it operates.
B.1
Pump control options
The various methods of pump control are made up of a combination of two control variables:
Pump duty
Indicates in what sequence pumps are started.
Pump start method
Indicates whether new pumps start and run with any currently running pumps (most
common) or whether new pumps start and shut off currently running pumps.
B.2
Pump groups
The device groups pumps that use identical pumping strategies based on the value of Relay
Control Function [Relay function (2.8.1.4.) (Page 195)]. Generally, one group of pumps
corresponds to one wet well or reservoir.
B.3
Pump by rate
To trigger pump starts by the rate of change in material level, use Pump by rate (2.8.1.8.)
(Page 198). New pumps are started, one at a time, until the rate setpoint [Filling indicator
(2.3.9.) (Page 176), or Emptying indicator (2.3.10.) (Page 176)] is reached.
B.4
Pump control algorithms
Fixed
Starts pumps based on individual setpoints and always starts the same pumps in the same
sequence.
Alternate
Starts pumps based on the duty schedule and always leads with a new pump.
