Basic Principles of the Pump Cleaning Sequence
Starting the PCS
The PumpSmart PS220 must be in Remote control, show a “Start Received “command, and running a pump.
When the Pump Cleaning function is initiated, all PS220 functional control is disabled. It is automatically
enabled once the function completes.
Notes
1. The PCS cannot be run in “Local” control.
2. The request and execution of the PCS is blocked for 3 seconds after a start command, and after a
completed PCS, to prevent increased starting torque levels from motor starts from triggering a false request
for the PCS to execute automatically.
Stopping/Interrupting the PCS
There are two methods that can stop the execution of the PCS:
1. Issuing a Stop signal.
2. Opening Digital Input 3 (DI3), if it was used to start the PCS.
Note:
When either of these choices is used to stop the PCS the PumpSmart PS220 will need to be restarted. It will
not restart on its own.
Disabling the PCS
To completely disable this function, you will need to configure the setting of parameter 83.01 EXE P CLEAN
SEQ to “NOT SELECTED”, and 83.02 to NOT SELECTED.
PCS in Multipump Applications
In Multipump Synchronous control, only one pump shall be permitted to execute the PCS at a time. The
other pump(s) shall be held in queue until they individually become available to execute their PCS routines.
Note:
Setting parameter 83.02 is set to TORQ or TORQ OR RUN TIME, will require a “Torque Test” to be performed
to ensure that the setting for parameter 83.03 TORQUE REQ is suited for the application. This test may also
be required for the Pump Snore functionality.
