Example:
In process Control Mode your system setpoint is 100. 97% of this vale is 97. The Protection Limit will become active when
the actual value reading of the process is 97 or below.
This event could be the result of a number of upset conditions both internal and external of the pump. The PumpSmart
PS220 cannot determine what the cause of the event is but it will provide the desired notification and response if the
event does occur.
2. Advanced Pump Protection.
The Advanced Pump Protection functionality uses the full array of the PumpSmart PS220’s feedback from SmartFlow and
Smart TDH in identifying upset conditions that may occur in the system.
This configuration will use these values of Dry Run, Minimum Flow and Runout Flow, along with the responses you estab-
lish, to define the systems reaction to these events. This protection is considered to be “Sensorless”. A flow meter can also
be used for this protection with the exception of Dry Run.
NOTE:
1. The Basic Pump Protection choice and the Advanced Pump Protection choice cannot both be used together.
2. The Keypad will show the specific warning and alarm message signifying when they occur. The list of events will be
as follows:
This functionality can be configured with the PumpSmart PS220 Configuration Wizard. To access this Wizard from the
Home Screen, follow the path: Menu>PS220 Configuration>Pump & VFD Protection>Pump Protection>Yes> Follow the
prompts
Advanced Pump Protection.
To configure the Advanced Pump Protection the individual steps that will be performed are:
1. Configure the choice for Advanced Pump Protection.
2. Configure the use of an external flow meter as the flow feedback source.
There are two choices for this configuration:
A. No (Default). Utilizes the Smartflow functionality to determine flow values.
B. Yes. This choice requires an external flowmeter. If a Flowmeter was not configured when the Process Control Wizard
was completed it will need to be added and configured. This Wizard will continue and guide you through the steps in
adding and fully configuring it for use.
Notes:
1. This choice cannot be used for Pump Protection on an individual pump in Multipump Control.
2. If you are unsure how to configure the external Flowmeter, please refer to the Analog Input configuration section in this
manual.
