Appendix D: Pump Control Reference

Please note that some pump control features apply to the MultiRanger 200 only.

The MultiRanger has the pump control strategies to solve nearly any water / wastewater application. This section details these strategies for engineers requiring in-depth knowledge of the system and how it operates.

Pump Control Options

The various methods of pump control are made up of a combination of two control variables:

Pump Duty

The pump duty indicates in what sequence pumps are started.

Pump Start Method

The 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.

Pump Groups

The MultiRanger groups pumps that use identical pumping strategies based on the value of Relay Control Function (P111). Generally, one group of pumps corresponds to one wet well or reservoir.

Pump by Rate [MR 200]

Please note that this feature applies to the MultiRanger 200 only.

To trigger pump starts by the rate of change in material level use P121–Pump by Rate (P121). New pumps are started, one at a time, until the rate setpoint (Filling Indicator (P702), or Emptying Indicator(P703)) is reached.

Pump Control Algorithms

Please note that the MultiRanger 100 and the MultiRanger 200 use this feature differently.

MultiRanger 100

All of these algorithms can be used to start multiple pumps (assist).
