LMR PLUS Electric Fire Pump Controllers with Transfer Switch Features January 2012 FT60 Reduced Voltage - Autotransformer Electrically and Mechanically Interlocked The FT Series transfer switch operating mechanisms are mechanically interlocked to prevent the normal and alternate source from connecting at the same time. The switch operates upon signals received from the ATC-300 Plus controller. 1-1 Automatic Transfer The FT Series Transfer Switches will perform an automatic transfer from Normal to Alternate source when the Voltage drops to 85% of normal, or there is a loss of any phase and/or Phase Reversal. ATC-300 Plus Product Description The Automatic Transfer Switch Option may be added to any FD type Fire Pump Controller whenever automatic transfer from normal to alternate power is required. The automatic Transfer Switch and Fire Pump Controller are mounted in the same enclosure or in separate enclosures to form one unit and interwired - depending on the horsepower and voltage required. Engine Test Button An engine test button is provided on the ATC300 controller that can be used to test the Source 2 (generator) engine. The operator can select the engine run test time (0-600 minutes). As well, a silence pushbutton is provided which de-energizes the alarm bell. The panel mounted, multi-function, microprocessor based ATC-300 Plus controller accurately monitors two power sources and provides the necessary intelligence to reliably operate the transfer switch through a series of programmed sensing and timing functions. Keypad Programming The ATC-300 Plus controller membrane is equipped with seven keypad input buttons which are used to program the controller as well as set operating parameters. LED Status Indication Five LED’s indicate the status of the power sources. Source 1 Available Source 1 Connected Source 2 Available Source 2 Connected Unit Status Voltage and Frequency Sensing The ATC-300 Plus continuously monitors the normal source for out of range setpoint values. When the source is outside the dropout setpoints, the source will become unavailable. This prompts a transfer to the alternate source. Retransfer occurs when the normal source’s frequency and/or voltage return within pickup setpoints. Alarm Relay The alarm relay is de-energized to indicate an absence of an alarm state and energized to indicate the presence of an alarm condition. Alarm conditions include: Improper Circuit Breaker Operation Motor Operator Failure Lockout Failsafe Condition Aborted Engine Test Aborted Plant Exerciser Unsuccessful in-phase Transition Product Features Power I/O Board The FT60 Transfer Switch Controller utilizes an autotransformer that is inserted in the power supply to the motor to reduce the voltage at the motor terminals and to provide a smooth acceleration. The main contactor by-passes the autotransformer after a short acceleration time and applies full voltage to the motor terminals. Starting line current is 28% of the across-theline starting inrush for controllers 60HP and up; 45% of across-the-line starting inrush of controllers 50HP and smaller. The FT60 can be programmed for either fully automatic or semiautomatic operation. Transformers Logic Controller Board Communication Incoming line voltage is run directly to the I/O board from the incoming lines. The three transformers mounted on the I/O board will accept voltage inputs between 100 and 600V. Customer Connection Terminals Connection terminals for external customer connections, are located on the top of the Power I/O board. Ethernet Port An optional ethernet port is used for direct connection to a computer for data transfer. RS485 Serial Port 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). An optional RS485 serial port can be provided for communication to various external software programs. Embedded Web Page A buzzer is mounted on the logic board which will operate if Fail to Start, Hardware Malfunction or any Common Alarm condition exists. 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. Buzzer Output Relays Seven socket mount, 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, Startup, Acceleration and Future # 1. Each socket has an LED mounted on the I/O board which indicates each relay’s coil status. Optional Output Relay Boards There is provision to add up to eight additional USB Port / USB Drive 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 stick). 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 conguration. Each board provides an area for the user to label the terminal number and relay name. For more information visit: www.chfire.com BR05805061K/K
