LMR PLUS Electric Fire Pump Controllers Powering Business Worldwide FDM Medium Voltage Controller Product Description For over 50 years, EATON Corporation has been the industry leader in Medium Voltage Motor Control. The FDM Medium Voltage Fire Pump Controller is based on the AMPGARD® controller design which incorporates Eaton's industry leading Cutler-Hammer TRITON ™ SL Series Medium Voltage Vacuum Contactor. The SL Contactor utilizes Eaton's Cutler- Hammer vacuum interrupters that exhibit both a long electrical life and a high interruption Product Features Microprocessor Control The FDM Medium Voltage controller incorporates LMR Plus technology, which is an enhanced version of the original Programming remains straightforward due to the retention of the core firmware and similar menu structure present in previous models. The controller can be ordered with the option to display and output current values and status, on command, from various software An embedded web page for retrieving diagnostics and history reports, can be accessed from the optional Ethernet communication port. An optional Rs485 serial port can be used for direct connection to a computer for data ■ Door Mounted Membrane Keypad displays Pressure, Voltage, Amperage, Time & Date, Frequency, Alarms & Timers and Custom ■ Alarm & Status LED Indication ■ Custom Message Display ■ Custom Inputs & Outputs ■ Information can be saved to USB Drive ■ Optional Output Relay Boards * COM Option must be ordered to enable this The LMR Plus controller section has it's own separate entrance door and is segregated from the medium voltage section. Power connections are accessible through the front of the controller and are fully isolated from the medium voltage A positive mechanical isolating switch with visible disconnect, completely grounds and isolates the contactor from the line connectors. This is achieved using a mechanically driven isolating shutter, which minimizes access to exposed high voltage components and wiring. Since all components are front accessible, routine inspection or parts replacement is easily achieved. Design Simplicity Component-to-component direct connection reduces the number of electrical wire connections by over half, making troubleshooting faster and easier. Space Heater Included as standard is an internal space heater, which is powered from the test plug circuit. It is not necessary to apply medium voltage power to turn on the heater. Operating Devices The two external operating devices are manufactured by EATON. They are Dust- Tight/Oil-Tight pushbuttons and provide the following functions: Start: Allows for local (manual) starting of the motor. The "Local Start" LED illuminates on the Stop: De-energizes the SL-400 Vacuum main Mechanically Locked Since the medium voltage door is mechanically locked with the disconnect switch, access to the MV component section is prevented while medium voltage power is applied to the unit. Power Fuses The FDM controller incorporates fatique proof Current Limiting fuses. When properly applied, the element of the fuse will not age, become brittle or deteriorate under the most severe duty cycling. A spare set of R rated fuses are provided in the spare fuse compartment inside the front door of the The FDM comes standard with a NEMA Type 2 (IEC IP11 ) drip-proof, powder baked finish, free- standing enclosure. A NEMA 4, 4X enclosure is available as an option. A tin-plated copper bus is provided in the incoming / load section of the FDM controller for grounding Control Transformer fuse protection is provided by primary fuses. The TRITON™ SL 400 contactor uses three Axial Magnetic (A-M) coils at the fixed end of the vacuum interrupters. The A-M coils establish a magnetic field within the interrupter during fault conditions. The field disperses the arc during fault current interruption, allowing the contactor to interrupt a very high fault current. For more information visit: www.chfire.com
