Description

The Tornatech Model GPR-380V/200HP/3PH/60Hz is a full-service, reduced voltage electric fire pump controller engineered strictly in compliance with NFPA 20 standards. This system is specifically deployed in installations where the local electrical supply or generator capacity cannot handle the massive voltage dips associated with full-voltage across-the-line starting. By leveraging a heavy-duty autotransformer configured with a 65% voltage tap, the panel restricts initial motor inrush current to just 42% of standard line levels. It implements a rapid, two-step closed transition sequence that guarantees continuous power delivery during acceleration, avoiding damaging line spikes before stepping up to full voltage. Housed in a rugged, red powder-coated NEMA 2 drip-proof enclosure, the controller is equipped with a door-mounted ViZiTouch 7-inch color touch screen HMI for comprehensive system monitoring, real-time pressure recording via an integrated stainless steel transducer, and an external mechanical emergency start handle for absolute override safety.

Features

  • Reduced Inrush Current Shielding: Suppresses initial line current to 42% of normal starting values, protecting localized weak grids, transformer networks, and backup diesel generator sets from catastrophic voltage drops.
  • Closed Transition Starting: Employs an autotransformer circuit that keeps the pump motor continuously connected to power during the step-up transition, eliminating transient voltage spikes and secondary mechanical shock waves.
  • ViZiTouch Screen Navigation: Houses a premium 7-inch color touch screen HMI that displays clear digital metrics for multi-phase voltage/amperage, continuous loop pressure curves, and active alarm tracking.
  • Emergency Mechanical Override: Outfitted with a heavy-duty, flange-mounted external emergency run handle that mechanically overrides all electronic logic to instantly clamp the contacts closed across-the-line.
  • Expanded Diagnostic Logging: Integrates internal flash registers that record up to 7 days of continuous system pressure changes and 15 days of operational event history, easily downloadable via a front-accessible USB port.
  • Dual-Mechanism Safety Handle: Links the isolation switch and circuit breaker mechanisms to a single physical handle that is structurally interlocked with the front door mechanism in the “ON” safety position.
