Powering Business Worldwide LMR PLUS Electric Fire Pump Controllers FD50 Reduced Voltage - Primary Resistor Product Description The FD50 LMR Plus controller is selected when it is necessary to meet limitations on inrush current. A resistor is inserted in the power supply to the motorfora smooth acceleration. The main contactor by-passes the resistor after a short acceleration time and applies full voltage to the motor terminals. Starting line current is 65% of the across-the-line starting inrush (approximately 390% of rated full load either fully automatic or semi-automatic retrieving diagnostics and history reports, along with USB and Ethernet communication ports for downloading data, make the LMR Plus Series of controllers easy to troubleshoot and maintain. As well, critical information can be easily accessed and used for report generation and analysis, which aids in providing effective, reliable fire protection. Product Features Logic Controller Board The controller can be ordered with the option to display and output current values and status, on command, from various software protocols through the appropriate port(s). The web page is a multifunction tool that allows the user to view the controller's current status, data values, programmed set points and history. It is accessed using the optional ethernet port. Ethernet Port An optional Ethernet port can be used for direct connection to a computer for data transfer. An optional RS485 serial port can be provided for communication to various external software The logic controller board is equipped with a USB port that can be used to transfer data to and from a portable USB Drive device (memory A buzzer is mounted on the logic board which will operate if Fail to Start, Hardware Malfunction or any Common Alarm condition Incoming line voltage is run directly to the I/O board from the incoming lines. The I/O board will accept voltage inputs between 100 and Customer Connection Terminals Connection terminals for external customer connections, are located at the top of the Power Membrane Keypad Door Mount The membrane keypad is accessible from the front door of the controller. Output Relays Five, 8 Amp, 2 Form - C (DPDT) output relays are provided standard on each power I/O board. They are designated for: Common Alarm, Phase Failure, Phase Reversal, Pump Run and Future #1. Each socket has an LED mounted on the I/O board which indicates each relay's coil Optional Output Relay Boards There is provision to add up to eight additional relay outputs, via optional relay output boards. Each board contains a maximum of 2 additional relays. The Power I/O Board will accept a maximum of 4 optional boards which mount in a snap-on configuration. Each board provides an area for the user to label the terminal number and relay name. Drain Valve Solenoid All LMR Plus electric controllers are equipped with a drain valve solenoid used for weekly test When using an external USB Drive, the drive should conform to the following specifications: All LMR controllers come standard with NEMA 2 enclosures unless otherwise ordered. Available Emergency Start Operator emergency start handle switch input. NEMA Rating The standard membrane keypad is rated for Alarm & Status LED's A total of 20, ( 10 Status -10 Alarm ) LED's provide indication on the membrane keypad. Status LED's Pump Running Local Start Remote Start Deluge Valve Emergency Start Auto Shutdown Enabled Alarm LED's Phase Reversal Phase Failure Locked Rotor Trip Silence Button A silence pushbutton on the membrane can be used to silence the buzzer. When an alarm condition exists, the alarm buzzer will sound. If the Silence Alarm button is pressed, the alarm buzzer will turn off. If a subsequent alarm condition occurs after the silence button is pressed, the buzzer will re-sound. Pressing the Silence Alarm button again, will silence the Motor Test Button The motor test button on the membrane can be used to simulate an automatic start. Automatic Shutdown Enabled When the Automatic Shutdown function is enabled, a Green LED will indicate on the controller membrane. Standards & Certification The LMR Plus Electric Fire Pump Controllers meet or exceed the requirements of Underwriters Laboratories, Underwriters Laboratories Canada, Factory Mutual, the Canadian Standards Association, New York City building code, CE mark and U.B.C / C.B.C. Seismic requirements, and are built to NFPA 20 For more information visit: www.chfire.com
