MagVFC"' Variable Frequency Controller <br />Variable speed pumps are controlled by the MagVFC'" <br />variable frequency controller which provides control for <br />both 2 Hp and 4 Hp variable speed STPs. Features include: <br />• Faster fill times during peak hours and power savings <br />during non -peak hours. <br />• Control is determined through the PMA power <br />consumption, eliminating the need for a transducer or <br />special wiring. <br />• Setup selections include 2 Hp or 4 Hp, MLD or PLLD, <br />gas or diesel, and Master -Slave, alternating circuit <br />manifolded pump control options. <br />• Capable of networking with INCON— fuel <br />management systems for enhanced pump control <br />capabilities. <br />Diagnostic Fault Detection <br />The MagVFC" variable frequency controller features a <br />dual 7 -segment display that displays running status and <br />fault codes. A fault history on the controller also provides <br />an enhanced troubleshooting process with faults like: <br />Fault Detection Display Codes <br />1 11 <br />0_10_ UL = Underload: Dry run or blocked PMA intake <br />1 <br />LI = <br />Low Incoming: Input power under voltage <br />Lr = <br />Locked Rotor: Overloaded while PMA is running <br />1 11 <br />LU = <br />Locked Up: Overload at PMA startup <br />SC = <br />Short Circuit: Short typically from controller to PMA <br />j i <br />SU = <br />Shorted Upper: Short typically in controller <br />� w <br />OC = <br />Open Circuit: Broken connection to PMA <br />Er = <br />Extended Run: No power change for 60 minutes <br />jj <br />HO = <br />Hot Operation: Excessive controller temp / fan protection <br />
