Activation options
If the "Pump cleaning - mode" parameter is set to "Manual ", you can start and stop the pump
cleaning function as follows:
• 3RW5 HMI High Feature
Menu: "Control > Control motor > Pump cleaning start / stop"
Access protection to the 3RW5 HMI High Feature is not active or has been reset.
Refer to chapter Control via 3RW5 HMI High Feature (Page 232).
• With SIRIUS Soft Starter ES (TIA Portal) via the local interface on the 3RW5 HMI High Feature
Brief overview: Window "Task Card" > Tab "Online Tools" > "SIRIUS Control Panel"
• Input action (Page 194)
• With a fieldbus via a 3RW5 communication module:
– With SIRIUS Soft Starter ES (TIA Portal) Premium / Professional (only via a 3RW5 PROFINET
– Configuration software of the control system (e.g. STEP 7 with corresponding HSP)
– User program
You can find additional information on the parameters that can be set via the fieldbus in the
manual of the respective 3RW5 communication module.
Setting via 3RW5 HMI High Feature
• Menu: "Parameters > Soft Starter > Parameter set 1 / 2 / 3 > Condition Monitoring > Pump
cleaning"
• Access protection to the 3RW5 HMI High Feature is not active or has been reset.
Configuration of the system
If the 3RW55 or 3RW55 Failsafe soft starter detects a configured reversing contactor assembly,
the 3RW55 or 3RW55 Failsafe soft starter automatically uses the "with reversing switching
element" option (pump cleaning "intense") when starting the pump cleaning function. If
the 3RW55 soft starter does not detect a configured reversing contactor assembly, it
automatically uses the "with creep speed" option (pump cleaning "light"). In this case,
the 3RW55 Failsafe soft starter cannot start the pump cleaning function.
Depending on the requirement for the pump cleaning function, note the information on the
following pump applications:
Pump cleaning function with creep speed (Pump Cleaning "light")
This function is not available for the 3RW55 Failsafe soft starter.
This type of cleaning is suitable for preventing larger deposits of dirt. If the 3RW55 soft starter
detects changes in the operational current, the cleaning can be started normally. There are,
however, restrictions in this case. The pump cleaning function with creep speed can be operated
in reversing mode only in the "Creep speed" (Page 172) function.
