Operation Features |
Soft Fill |
Prevents pump damage caused by dramatic pressure changes during initial operation. |
Start/End Ramp |
Prevents pump damage by changing the acceleration and deceleration ramp profile
during initial pump operation and stop. |
Decel Valve Ramp |
Prevents pump or pipe damage caused by sudden pressure changes when pumps
are stopped or valves are closed. |
Scheduling (Time Event: Real Time Clock) |
Real Time Clock allows sequencing of selected functions during pre-defined time periods. |
Flow Compensatione |
Compensates for hydraulic losses due to elevation or long pipe lengths. |
Pump Clean |
Removes foreign substances from the pump cavity to extend life and improve efficiency. |
Load Tuning |
Estabilishes load curves (current & power) to define load characteristics for under
torque and pump clean funtions. |
Fire Mode |
Operates continuously to protect critical systems during emergency situations under
set frequency and direction. |
Energy Savings Display |
Commercial energy consumption is compared to the energy utilized by the VFD to
calculate the amount energy savings. |
