Eaton FT90 Soft Start Fire Pump Controller with Automatic Transfer Switch

The Eaton FT90 is the soft start model with automatic transfer switch in Eaton's EPCT Fire line of electric fire pump controllers. It combines a full-service, reduced-voltage soft start controller and a fire-pump-rated automatic transfer switch in one assembly, and it works with standard motors. Every FT90 is built to order, so we quote each one to your motor, voltage, enclosure and options. Call (786) 336-5783 or send us your catalog number or spec section.

How the FT90 works

The FT90 uses a solid-state starter that provides a step-less, smooth current ramp to the motor. This eliminates current surges and mechanical torque transients at start, which reduces stress on the motor, pump and piping. A soft-stop feature decelerates the motor smoothly as well, which helps reduce water hammer in the system. The integrated automatic transfer switch moves the fire pump to an alternate power source, such as a generator or second utility feed, when the normal source fails, and the EPCT Fire touchscreen manages both the controller and the transfer switch from one display.

FT90 controllers are supplied as dual utility controllers and meet FM 1321/1323 approvals. Other models with transfer switch include the FT30 across-the-line, FT40 part winding, FT60 autotransformer, and FT70 and FT80 wye-delta.

EPCT Fire features

• 7" color touchscreen: 800x480 high-resolution display, a fast processor that reduces input lag, and a simplified tab system for navigation and programming
• USB port: download history, statistics, configuration, diagnostics and start-up files; upload a configuration to reduce programming time; update firmware
• Event history: logs up to 65,000 time-stamped events, with on-screen filtering for troubleshooting
• Programmable output relays for common alarm, power/phase failure, phase reversal and pump run
• Optional boards:
  • Relay board: four (4) one form-C programmable output relays
  • MODBUS board: output communication via RS422 or RS485
  • Secondary 4-20mA device board: additional connections for external pressure transducers, temperature sensors and similar devices
  • Alarm board: a supervisory powered alarm output
• Enclosures: UL Type 2 (drip-proof) standard; Type 3, 3R, 4, 4X and 12 available
• Standards: built to NFPA 20, listed to UL 218, and FM 1321/1323 approved. See the bid submittal for the full list of approvals.

FT90 catalog numbers explained

Every EPCT Fire catalog number follows the same pattern. For example, FT90-60-D-L1-E5 is a 60 HP, 480V/60Hz soft start controller with transfer switch and English labels in a NEMA 4X 304 stainless steel enclosure.

Common options

FT90, FD90 or FD90 with FPATS?

If the fire pump doesn't need automatic transfer, the stand-alone FD90 soft start controller is the simpler option. Where the controller and transfer switch need to be separate, an FD90 can be paired with an FPATS stand-alone transfer switch.
