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.
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.
3. A “Complete Sequence” is defined by the number of cycles allowed to run. A full cycle is:
1. The PS220 coming to a complete stopping after initiating the PCS.
2. The PS220 running in the reverse direction until stopped during the PCS
3. The PS220 running in the forward direction until stopped by the PCS.
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 settings 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.
PCS Parameter Configuration Settings:
The following parameter settings are used to configure the Pump Cleaning Sequence.
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.
The test can be done as follows:
1. Switch to “LOCAL” Keypad Control.
2. Start the Pump by pressing the Green Start Button.
3. Set the Speed Reference to Max Speed and let the pump run to full speed. Check and validate that the
pump is pumping with a “normal level” in the sump, or the suction side tank and it is maintaining a stable
flow.
4. View/Record the value of Parameter 1 .10 MOTOR TORQUE in %. Multiply this value by 1.2. The factor 1.2
corresponds to the expected increased torque that can be expected when a clog may occur. Use this calculat-
ed value when you configure parameter 83.03 TORQUE REQ.
5. Stop the PS220 with the Red Stop Button.
6. Switch back to REMOTE control.
