FTA576E Jockey Pump Controller

Description

Firetrol FTA576E Jockey Pump Controllers are intended for use with fire pump systems. They are used for pressure maintenance in fire pump installations to prevent unnecessary operation of the main fire pump. FTA576E Jockey Pump Controllers use Wye-Delta Open Transition Starting which reduces motor current. When starting the motor will be connected in a wye configuration and draw approximately 33% of its normal inrush current and develop approximately 33% of its normal starting torque. After a time delay, the motor is automatically reconnected in delta, applying full voltage to the motor windings.

Brand

Firetrol

Firetrol, was founded in the early 1970’s and incorporated in Erie, Pennsylvania by an entrepreneur who saw an opportunity in a unique marketplace; the fire pump control industry. The business grew steadily between 1971 and 1980 as the company developed the first fire pump controller with molded case circuit breakers which drastically reduced their size, the first manual wound rotor controller for the New York City high-rise marketplace, the first medium voltage controller, and the first UL Listed controller with an automatic power transfer switch.

Specifications

Jockey Pump Controller
The auxiliary jockey pump controller, if required and specified on the plans and specifications, shall be factory assembled, wired, and tested and specifically designed for
this type of service. This controller shall be of the same manufacturer as the main fire pump controller.

Standards, Listings & Approvals
The controller shall conform to all the requirements of the latest editions of:
· NFPA 70, National Electrical Code.
The controller shall be listed by:
· Underwriters Laboratories, Inc., in accordance with UL508A, Standard for Industrial Controls
· Canadian Standards Association CSA-C22.2, Standard for Industrial Control Equipment (cUL)

Enclosure
The controller components shall be housed in a NEMA Type 2 (IEC IP22) painted steel, wall mounted enclosure (UL50E Construction).

Withstand Ratings (Short Circuit Current Ratings w/Circuit Breaker)
The jockey shall have standard short circuit current ratings of:
65kA @ 480 Volts Max. (3-Phase)
5kA @ 600 Volts (3-Phase)

Construction
The Jockey Pump Controller shall use Wye-Delta Open Transition Starting which reduces motor current. When starting the motor will be connected in a wye configuration
and draw approximately 33% of its normal inrush current and develop approximately 33% of its normal starting torque. After a time delay, the motor shall be automatically
reconnected in delta, applying full voltage to the motor windings. The controller shall incorporate a circuit breaker and horsepower rated motor starter, control circuit transformer with 24VAC secondary and 200-600V multi-tap primary, main disconnect switch, and a 0-600 psi (0-42 bar) solid state pressure transducer.

Operator Interface
The jockey pump controller shall feature an operator interface with user keypad. The interface shall feature a 4 digit digital display. The controller shall provide LED indicationof motor run (manual start and automatic start) and a Hand-Off-Auto Selector Switch shall be provided. User settings such as start/stop pressure settings, timer settings and units of measure shall be programmable from the user interface without opening the enclosure door.

Features

The following are included as standard with each controller:

NEMA Type 2 (IEC IP22) Painted Steel Enclosure
with 2 door latches
Circuit Breaker
Horsepower rated motor starter
Wye Delta Open Transition Starting
Minimum Run Timer
Pressure Display
Solid State Pressure Transducer
Hand-Off-Auto Selector Switch

Applications

Facilities using emergency generators where inrush current must be limited.
Large-scale industrial sites with long piping runs prone to pressure fluctuations.
High-rise buildings where mechanical vibration and water hammer must be minimized.
Professional fire pump rooms requiring digital diagnostics and historical data logging.
