Overview

The operating controls for the Pump Drive F600 are Hand, Off or Auto, which may be selected from the keypad interface, digital inputs or HMI/PLC control word.
Hand mode runs the pump at a user defined fixed speed, from either a digital pre-set or an analog reference.
In Auto Mode, the pump starts Automatically with a start delay when the wake condition is detected, for example a pressure transducer signal goes below wake threshold. Initially, a pipe fill operation may be performed to remove air from the pipes. A PID control then regulates the system to the setpoint, e.g. for a constant pressure system, the demand pressure will be regulated by adjusting the motor speed. If the pump detects a stop condition for a defined time period, it will Automatically stop and enter the Sleeping state. There are four main stop conditions - sleep on low motor speed, software no flow detection, no flow from a flow switch and low flow from a pulsed flow meter. All four conditions can be individually enabled to suit the system requirements.
In Off Mode, Hand and or Auto are not selected, the drive will not energise the motor. This is not a safety function; the Safe Torque Off function using T29 may be used as part of a safety system if required. In Cascade or Multi-leader parallel pumping systems, when the leader drive PID output is at maximum, additional assist F600s or soft starters are commanded to run. If the sleeping threshold is reached, additional assist F600s or soft starters are commanded to stop.
