Broken Pipe Protection
When DIP switch 1-6 is enabled, the Broken Pipe Detection feature will stop the system and display Fault
14 if the drive runs at full speed without reaching the configured broken pipe pressure setpoint.
•
For example, if the feature is enabled and the pressure is set to 25 psi, and if the VFD runs at full
speed with pressure less than 25 psi for 10 minutes, the VFD will stop and fault on F14. Manual reset
is required.
•
If the system is used with a sprinkler system or is being used in another high-flow system, this pro-
tection feature should be disabled.
•
This feature can also be enabled and adjusted using the mobile app.
IMPORTANT: The Broken Pipe Pressure setting must always be a value lower than any active Setpoint
pressure setting.
Underload Protection
The Underload Off Time determines how long the drive will wait before attempting to run following an
Underload event. The default time is Smart Reset (5 minutes, and double the time for each subsequent
reset attempt), but is user-adjustable through programming or via the mobile app from 1 minute to 48
hours.
