SUBMERSIBLE
PUMPING SYSTEMS
THREE-PHASE
SMART CONTROLLER
STP-SCIII is designed to replace three-phase motor starters
in both new and existing locations. The STP-SCIII controller
provides valuable pump protection and performance
features for an economical price.
HIGHLIGHTS
SPECIFICATIONS
Easy Retrofit
• Enclosure size: 9 1/16" × 7 6/8" × 5½"
(230 mm × 196 mm × 140 mm).
The STP-SCIII is compatible with most existing three-phase
submersibles from 3 to 5 hp. Retrofitting existing stations is as
simple as replacing the existing three-phase controller or
starter with the STP-SCIIII. No additional wiring is required.
Continuous Diagnostics
The STP-SCIII constantly monitors for abnormal conditions
that reduce motor life or cause downtime. When any of these
conditions exist, the STP-SCIII will alert the service technician
to the source of the problem: dry run, extended run,
overvoltage, undervoltage, relay fault, voltage/current
unbalance, locked rotor, phase loss or open circuit.
• Compatible with three-phase FE PETRO® 3 and 5 hp
submersibles and most competitive makes.
• Relay rating: 5 hp.
• Relay coil (hook) signal rating: 120 VAC.
• Pump “RUN” indication is provided by flashing green light.
• Power “ON” indication is provided by steady green light.
• Flashing red light indicates fault condition. Number of
flashes indicates specific fault.
• Audible alarm alerts operator of fault.
• Built-in voltage surge protection.
Pump Auto-Start
• Flashing yellow light indicates RS 485 is communicating.
Provides “on demand” automatic pump start of up to eight
submersible pumps manifolded to the same discharge line.
Lead pump starts to satisfy initial demand and additional
pumps are started as demand increases, reducing power
consumption and extending pump life.
• RS 485 com port which is provided to connect Smart
Controllers to each or to FFS EVO™ Series automatic tank
gauge (ATG) for enhanced functionality. When Smart
Controllers are connects to the EVO™ Series ATG via Turbine
Pump Interface (TPI), Smart Controllers and ATG can
leverage shared intelligence to further enhance capabilities
and run your business as efficiently as possible.
