Protection
4. Pump & VFD Protection Wizard
The PS220 Pump & VFD Protection functionality can be configured to
fully identify, notify, control, and prevent a pump in a system that may
operate in an underload, overload conditions, and all the adverse con-
ditions of dry-run, dead-head, minimum flow, runout, and cavitation. It
can also provide the pumping system protection to ensure that indirect
damage from conditions such as over pressure, water hammer, and liquid
temperature rise will not occur. The onboard logic can also monitor ex-
ternal devices that are an integral part of the pumping system to add an
additional level of protection as well.
Since the core functionality of the PumpSmart PS220 is that it is a Vari-
able Frequency Drive (VFD), it also provides the ability to identify and
react to the most common electrical system upsets such as Undervoltage,
Overvoltage, Overcurrent, Stall, Underload and Overtemp.
Please refer to the Features & Functions section in this manual for a more
detailed explanation of all this functionality. This Wizard will show the
step-by-step instructions to configure this functionality for use.
This Wizard is made up of 5 individual Wizards for distinctive functional
protections.
They are:
1. Pump Protection. There is a choice for:
A. Basic
B. Advanced.

vidual choices for Protection functionality.
