MiniRanger Plus – INSTRUCTION MANUAL

7ML19981CJ02

Pump Control Application 

The basic difference between a simple level application and a pump control application is 
that the relays assigned to pump function (P111) are normally de-energized (off) and 
energized when required to run the pump. In the program mode, pump relays are held de-
energized. 

Pumps can be programmed to work independently or in lead/lag fashion. Refer to 36. 

In applications where flooding is possible, a submersible transducer should be used. The 
submersible transducer's air cavity insures that a high level reading is maintained rather 
than establishing a loss of echo condition, when the liquid level reaches the transducer. 
When using a submersible transducer, set P802 = 1. 

Example 

The application is to control the level in a wet well. It is required that the level be 
displayed in centimetres. The transducer is mounted at 3.6 m from the bottom and is 
equipped with a submergence coupling as there is possibility of flooding in the well. Two 
pumps are to be controlled by the MiniRanger Plus in lead / lag fashion. The first pump to 
start at 1 m and the second pump to start at 2 m. Both pumps are to stop at 0.25 m. The 
maximum estimated filling rate is 1 m/min. In the event of a loss of echo, a fail-safe low 
after 6 sec is required to protect the pumps from running dry.
