ALARM AND CONTROL
An integral part of the core functionality of the PS220 is the ability for it to identify pumping system problems, provide
a notification, determine the possible causes, and to allow the customer to predefine and implement corrective action
measures automatically. The Alarm and Control Function allows for the predefining of these corrective actions. The
actions listed below are also an integral part of the Pump Protections Wizards.
For Basic Pump Protection:
The PumpSmart PS220 will either:
A. Issue a warning message signifying the event9s), and either run at minimum speed or stop. It can be configured to
automatically re-start after a delay period and then run again to try to maintain the process setpoint. It can be con-
figured to follow this routine a set number of times before a hard Fault is issued. The Fault will have to be reset, and
manually restarted.
B. A hard Fault is issued, and it will stop. The fault message will be displayed, and it will have to be reset, and manually
restarted.
For Minimum Flow Protection:
The PumpSmart PS220 will indicate that the pump is running at or below minimum flow with a message “Min Flow
Warning”. After the response delay time has expired. The event will be stored in the Event Log. The PS220 will then re-
spond based on the Protections Options. If and when a hard fault occurs it will display the message “Min Flow Fault”.
The PS220 will have to be reset and manually restarted. Please refer to the sections “Protection Options” and “Fault
Tracing” in this manual.
For Secondary Protection:
The PumpSmart PS220 will indicate a “Secondary Protect A, (B)” warning message, after the response delay time has
expired. The event will be stored in the Event Log. The PS220 will then respond based on the Protections Options.
With every occurrence, the event(s) are automatically logged in the PS220’s Event Log, which are Date and Time
stamped for historical analysis.
