FPATS - Electric Fire Pump Controller Transfer Switch Features - 1

FPATS Electric Fire Pump Controller Transfer Switch Features FPATS - Stand Alone Transfer Switch Transfer Switch Features Electrically and Mechanically Interlocked The FPATS 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. 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. Alarm Relay Product Description EATON’s Automatic Transfer Switches provide automatic transfer of an electrical load to a standby power supply in the event of drop or loss of voltage of any or all phases of the normal power supply. 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: Engine Test Button Improper Circuit Breaker Operation Motor Operator Failure Lockout Failsafe Condition Aborted Engine Test Aborted Plant Exerciser Upon the restoration of the normal supply, the electrical load is automatically re-transferred to the normal power supply. 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. Product Features Source 1 (Normal) Available 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. Five LED’s indicate the status of the power sources. Source 1 Available Source 1 Connected Source 2 Available Source 2 Connected Unit Status The white Source 1 Available LED illuminates when the Source 1 power source is within the setpoint ranges for the nominal voltage and frequency setting. Source 2 (Normal) Connected The green Source 1 LED illuminates when the Source 1 switching device and its associated position indicating auxiliary contact are closed. Source 2 (Emergency) Available The amber Source 2 Available LED illuminates when the Source 1 power source is within the setpoint ranges for the nominal voltage and frequency setting. Source 2 (Emergency) Connected 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. 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. The red Source 2 Connected LED illuminates when the Source 2 switching device and its associated position indicating auxiliary contact are closed. Input Pushbuttons Step / Enter The Step/Enter pushbutton allows the user to scroll through the information and setpoint displays. When the Step/Enter button is pressed, the information on the LCD display advances through the voltage(s), frequency, and status condition of Source 1, then Source 2, then the time and date information, then the history information, then the setpoints - one step at a time. For more information visit: www.chfire.com The Increase button allows the user to increase the value of the setpoints. When the ATC-300 is in the “Program” Mode, each time the Increase button is pressed, the value of the displayed item will increase by one. The Decrease button allows the user to increase the value of the setpoints. When the ATC-300 is in the “Program” Mode, each time the Decrease button is pressed, the value of the displayed item will decrease by one. Alarm Reset Function Pressing the Increase and Decrease buttons simultaneously will reset the Alarm function. If this is done while viewing any of the historical logged values in the program mode, the value of the current item resets to zero. Bypass Time Delay Function (Step/Enter+Help/Lamp Test) Pressing the Step / Enter and Help / Lamp Test buttons simultaneously, will bypass the TDNE or TDEN functions when they are actively timing. Help / Lamp Test If the Help/Lamp Test pushbutton is pressed when a message is present on the LCD Display, a detailed description of the message will appear. It will scroll across the bottom of the display. If the LCD Display is displaying the Home screen when the Help/Lamp Test key is pressed, all of the LED’s will momentarily illuminate, then the following information will scroll across the display: Serial Number of the ATC-300 Plus controller, Hardware Revision number, Software Versions and Revision number, Feature Code, Firmware Version
