Description
The Tornatech Model GPR-380V/400HP/3PH/60Hz is a full-service, reduced voltage electric fire pump controller engineered strictly in compliance with NFPA 20 standards. This high-capacity system is specifically deployed in massive industrial complexes, municipal water installations, and large-scale commercial infrastructures where the electrical grid or backup generator system cannot support the severe voltage drops caused by across-the-line full-voltage starting of a powerful 400 HP motor. Utilizing a heavy-duty autotransformer with a 65% voltage tap, the controller restricts initial motor inrush current to just 42% of normal line levels. It implements a rapid, two-step closed transition sequence that guarantees continuous power delivery during acceleration, avoiding destructive line surges before shifting cleanly to full operational line voltage. Housed in a rugged, red powder-coated NEMA 2 drip-proof enclosure, the controller features a door-mounted ViZiTouch 7-inch color touch screen HMI for precise telemetry tracking, real-time pressure diagnostics 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.
