EMD-FL-PF-400 Electronic monitoring relay for load monitoring in single and three-phase networks, based on the power factor cos INTERFACE Data sheet 102914_en_02 1 (c) PHOENIX CONTACT - 09/2009 Description Increasingly higher demands are being placed on safety and system availability - across all sectors. Processes are becoming more and more complex, not only in mechanical engineering and the chemical industry, but also in plant and automation technology. Demands on power engineering are also increasing constantly. Features - - - - - - Error-free and therefore cost-effective operation can only be achieved through continuous monitoring of important network - and system parameters. Electronic monitoring relays in the - EMD series are available for a wide range of monitoring tasks - to avoid the consequences of errors or to keep them within limits. Overload monitoring Underload monitoring Window function Adjustable threshold values Adjustable starting override Adjustable response delay Error memory Wide-range power supply unit Two PDTs The operating states are indicated using colored LEDs, errors that may occur can be sent to a control system via a floating contact or can shut down a part of the system. Some device versions are equipped with startup and response delays in order to briefly tolerate measured values outside the set monitoring range. WARNING: Risk of electric shock Never carry out work when voltage is present. Make sure you always use the the latest documentation. It can be downloaded at www.phoenixcontact.net/download.

For all functions the "MIN" and "MAX" LEDs flash alternately if the minimum value selected is greater than the maximum value. The "FUNCTION" rotary switch is used to set the desired function: - O = Overload monitoring (OVER) - OL = Overload monitoring with error memory (OVER + LATCH) - U = Underload monitoring (UNDER) - UL = Underload monitoring with error memory (UNDER + LATCH) - W = Monitoring of the area between thresholds MIN and MAX (window function) (WIN) - WL = Monitoring of the area between thresholds MIN and MAX (window function) with error memory (WIN + LATCH) 102914_en_02 PHOENIX CONTACT 6 EMD-FL-PF-400 Overload Monitoring (OVER and OVER + LATCH) U LED U/t LED MAX LED MIN OL OVER+LATCH LED REL,R Max Min START DELAY <DELAY DELAY START If the measured power factor exceeds the value set at the "MAX" controller, the set response delay (DELAY) starts (red "MAX" LED flashes). After the delay time has elapsed (red "MAX" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). If the measured power factor falls below the value set at the "MIN" controller (red "MAX" LED is OFF), output relay "R" picks up again (yellow "REL" LED is ON). If the error memory has been activated (OVER + LATCH) and the measured power factor has exceeded the value set at the "MAX" controller for longer than the set response delay, output relay "R" does not pick up if the power factor falls below the value set at the "MIN" controller. Once the error has been reset (supply voltage interrupted, e.g., using an external button), output relay "R" picks up when the supply voltage is applied again and the measuring cycle starts again once the set starting override (START) has elapsed.

If the measured power factor exceeds the value set at the "MAX" controller, output relay "R" picks up again (yellow "REL" LED is ON). If the error memory has been activated (UNDER + LATCH) and the measured power factor has fallen below the value set at the "MIN" controller for longer than the set response delay, output relay "R" does not pick up if the power factor exceeds the value set at the "MAX" controller. Once the error has been reset (supply voltage interrupted, e.g., using an external button), output relay "R" picks up when the supply voltage is applied again and the measuring cycle starts again once the set starting override (START) has elapsed.

PHOENIX CONTACT 7 EMD-FL-PF-400 Window Function (WIN + LATCH) If the error memory has been activated (WIN + LATCH), an error that has occurred must be reset by interrupting the supply voltage (e.g., using an external button). Output relay "R" then picks up when the supply voltage is applied again and the measuring cycle starts again once the set starting override (START) has elapsed. U LED U/t LED MAX LED MIN WL WIN+LATCH LED REL,R Max Min START DELAY START DELAY START Detecting Switched Off Loads If the current flow between L1i and L1k is interrupted (yellow "I=0" LED is ON) and no stored errors are present, output relay "R" picks up or remains picked up (yellow "REL" LED is ON). When the current flow is present again, the measuring cycle starts again once the set starting override (START) has elapsed.
