SPECIFICATIONS
MagVFC™ Variable Frequency Controller
Variable speed pumps are controlled by the MagVFC™ variable
frequency controller which provides control for both 2 hp and
4 hp variable speed STPs. Features include:
• Faster fill times during peak hours and power savings during
non-peak hours.
• Control is determined through the PMA power consumption,
eliminating the need for a transducer or special wiring.
• Setup selections include 2 hp or 4 hp, MLD or PLLD, gas or
diesel, and Master-Slave, alternating circuit manifolded
pump control options.
• Capable of networking with INCON™ fuel management
systems for enhanced pump control capabilities.
Diagnostic Fault Detection
The MagVFC™ variable frequency controller features a dual
7-segment display that displays running status and fault
codes. A fault history on the controller also provides an
enhanced troubleshooting process with faults like:
Fault Detection Display Codes
UL = Underload: Dry run or blocked PMA intake
LI
= Low Incoming: Input power under voltage
Lr
= Locked Rotor: Overloaded while PMA is running
LU = Locked Up: Overload at PMA startup
SC = Short Circuit: Short typically from controller to PMA
SU = Shorted Upper: Short typically in controller
OC = Open Circuit: Broken connection to PMA
Er
= Extended Run: No power change for 60 minutes
HO = Hot Operation: Excessive controller temp / fan protection
