Pump Cleaning Function (PCS)
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 operation by moni-
toring 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”. This 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.
NOTICE
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.
