Electric Fire Pump Controllers

Specifications for LXi 1400 Controllers * Primary Resistor Starting * July 2002

The fire pump controller shall be factory assembled, wired, and tested as a unit assembly, shall conform to the requirements of the latest editions of NFPA-20andNFPA-70,and shall be Listed/Approved by and bear the label of UL/FM. The controller shall beHubbell-LexingtonLXi 1400 equipped withLXi logic.

The controller shall be of the combined manual/automatic type and be furnished in a floor mounted drip-proofsteel Type 2 enclosure with lifting eyes. The enclosure shall be red with anon-glaresurface. The controller shall be for primary resistor starting and designed, tested, and marked for the rated horsepower and3-phasevoltage and frequency in a 40 degree C. ambient.

All electrical components shall be accessible from the front for maintenance and service. No components or component wiring shall be permitted on the door of the enclosure. The controller shall have a common operating handle for both the line isolating switch and the controller circuit breaker mounted in the enclosure flange. The minimum withstand rating for the fire pump controller shall be 150,000 amps RMS symmetrical at 200-600volts.The unit shall be Listed/ Approved with UL/FM as “Suitable For Use As Service Equipment”.

The controller shall have separate and independent pressure settings with minimum run timing capable of a setting of 10 minutes. Settings of the pressures shall be established at the time of the field acceptance test. Provisions shall be included to allow manual or automatic shutdown in the field.

The controller shall have two sets of Form “C” contacts for Pump Running, Phase Reversal, Power/Phase Failure, and one set of Form “C” contacts for Trouble. The Trouble contacts shall be activated by the following conditions: Invalid Configuration Memory, Emergency Manual Start, Pump Running, Phase Failure, Phase Reversal, Overload, Locked Rotor, Fail-to-Start,and Lockout.

The controller shall be equipped with LXi intelligent fire pump control system logic. All firmware shall benon-volatileflash based CPLD(complex-programmable logic device). Theboot-uptime for the logic shall be 3 seconds or less. Controllers that do not bootup and allow the pump to be started in 3 seconds or less are not acceptable. An RS232 serial port shall be supplied for downloading event history to a PC for analysis and printing.

The digital pressure readings and settings shall be displayed on the LXi LCD mounted on the enclosure flange. The LCD screen shall be 4 x 20 (4 lines of 20 characters) per screen, and the screens may be scrolled to give a total of 320 characters. The real time display shall givesimultaneous 3-phasedigital amps and volts for the pump power, and digital display for the system pressure. Controllers that do not simultaneously display digital3-phaseamps,line-to-linevolt readings, and system pressure, are not acceptable.

The event alarm caches shall be compartmentalized, and no compartment shall over-rideany other compartment. The compartments allow for analysis of four types of information events without having to look through all events including those not related to a problem. Events shall be shown with Date and Time for each event occurrence:

1.Events that have occurred during a pump idle period

2.Events that occurred during the last start period

3.Events that occurred during the last run period

4.Events that occurred during the last stop period.

The LED displays shall be mounted on the enclosure flange and have an LED for the following, with provisions for five spare LED’s to be available and programmable for other options or event displays.
