Pumping Functions

 

Overview

This chapter describes the functions included in the Pumping Library.

This library contains function blocks that allow you to execute the following tasks:

opump PID stage control

odevice switching control

oFS pump control, VS pump control, VSD control

ofriction loss compensation basic and friction loss compensation by using the flow value to calculate an adjusted setpoint

ocavitation protection

opump availability status verification and VSD availability status verification

odetection of the device priority

oauxiliary pump control

opipe fill control

ocontrol by operator interface

oauxiliary pump control by operator interface
