Functions
7. Water Functions Wizard
The PS220 Water Functions will provide the functionality to alleviate common
problems associated with pumping systems in the Municipal and Industrial
marketplace. Many of the uses for these can l be found in the Waste Treat-
ment, Water Treatment, and Water Distribution areas of these facilities.
The functions are as follows:
1. Pump Cleaning.
2. Pump Snoring.
3. Pipe Cleaning.
4. Pipe Filling.
Each of these functions has an individual PS220 Wizard to assist you with
configuring the functionality.
7.1 Pump Cleaning Sequence (PCS)
Wizard
The main function of the pump cleaning sequence (PCS) is to automatically
detect and remove substances that may have become lodged in the pump or
an inlet vane of the pump impeller. The PS220 can detect this during oper-
ation by monitoring the actual motor torque value (1.10 MOTOR TORQUE).
This vale is then compared to a higher reference threshold value (83.03
TORQUE REQ). When the actual value exceeds the reference threshold value
for a certain time period (83.04 TON REQ), the pump cleaning sequence will
be executed. The pump cleaning sequence can also be executed at a preset
time, every day, to serve as a preventive measure and a complement to the
automatic detection and removal of debris that can become lodged in pump
components on clog prone pumping applications.
The PCS is controlled in a way that is referred to as “request” and “execute”.
The control is defined by the settings of parameters:
1. 83.01 EXE P CLEAN SEQ
2. 83.02 REQ P CLEAN SEQ.
The PCS can be executed based on these choices:
1. Automatically at the detection of clog.
2. Automatically at specified time of every day.
3. Manually at any time.
Do not use the Pump Cleaning System for pumps which have threaded on impellers or
rotating shaft parts which can loosen or jam during reverse rotation. Failure to follow
these instructions could result in equipment damage.
