EMD-FL-3V-690 Electronic monitoring relay for voltage monitoring in three-phase networks INTERFACE Data sheet 103233_en_01 1 © 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. Undervoltage monitoring Window function Phase sequence monitoring Phase failure monitoring Asymmetry monitoring Adjustable threshold values Adjustable response delay Power supply via power module can be selected 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.

To install the power module in the relay housing, remove the transport casing and position the power module in the recess in the side of the housing (ensure that it is the right way round). The red locking latches snap in with an audible click when the power module is securely positioned. To remove the power module, press the two red locking latches together and pull out the power module. 103233_en_01 PHOENIX CONTACT 4 EMD-FL-3V-690 8 Installation WARNING: Risk of electric shock Never carry out work when voltage is present. The module can be snapped onto all 35 mm DIN rails according to EN 60715. 9 Diagnostics The LEDs indicate the following error states: "ASYM" LED (Red) – – LED flashes: Set threshold value exceeded, set delay time is running LED ON: Set threshold value exceeded, delay time has elapsed "MIN" and "MAX" LEDs (Red) – – – LED flashes: Set threshold value exceeded, set delay time is running LED ON: Set threshold value exceeded, delay time has elapsed Both LEDs flash alternately: Lower set threshold value is greater than upper threshold value "SEQ" LED (Red) – LED ON: Phases connected incorrectly. LED lights up immediately, relay drops out without delay. "REL" LED (Yellow) – – LED ON: Output relay has picked up LED OFF: Output relay has dropped out 103233_en_01 PHOENIX CONTACT 5 EMD-FL-3V-690 10 Connection example L1 L2 L3 N max. 20 A A1 15 L1 L2 16 L3 15 25 16 18 26 28 18 A2 25 26 28 3 ~ 690 V measuring range with 400 V AC power module (3 ~ 690 V AC mains) 11 Function If an error is present when the monitoring module is activated, output relay "R" remains dropped out and the LED for the corresponding threshold value lights up. 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: – U = Undervoltage monitoring (UNDER) – US = Undervoltage Monitoring With Phase Sequence and Phase Failure Monitoring (UNDER + SEQ) – W = Monitoring of the area between thresholds MIN and MAX (window function) (WIN) – WS = Monitoring of the area between thresholds MIN and MAX (window function) with phase sequence and phase failure monitoring (WIN + SEQ) 103233_en_01 PHOENIX CONTACT 6 EMD-FL-3V-690 Undervoltage Monitoring (UNDER and UNDER + SEQ) U LED U LED MAX If the measured voltage (average value of the linked voltages) falls below the value set at the "MIN" controller, the set response delay (DELAY) starts (red "MIN" LED flashes). After the delay time has elapsed (red "MIN" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). If the measured voltage exceeds the value set at the "MAX" controller, output relay "R" picks up again (yellow "REL" LED is ON). LED MIN LED REL, R MAX MIN START DELAY < DELAY Window Function (WIN and WIN + SEQ) U LED U LED MAX LED MIN LED REL, R MAX MIN DELAY < DELAY DELAY Output relay "R" picks up (yellow "REL" LED is ON) if the measured voltage (average value of the linked voltages) exceeds the value set at the "MIN" controller. If the measured voltage 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). Output relay "R" picks up again (yellow "REL" LED is ON) if the measured voltage falls below the maximum value again (red "MAX" LED is OFF). If the measured voltage falls below the value set at the "MIN" controller, the set response delay (DELAY) starts (red "MIN" LED flashes). After the delay time has elapsed (red "MIN" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). Phase Sequence Monitoring (SEQ) Phase sequence monitoring can be enabled for all functions. In the event that the phase direction has been modified (red "SEQ" LED is ON), output relay "R" drops out without delay (yellow "REL" LED is OFF). Phase Failure Monitoring (SEQ) In the event that one of the phase voltages fails, the set response delay (DELAY) starts (red "SEQ" LED flashes). After the time delay has elapsed (red "SEQ" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). Reverse voltages (e.g., motors that continue running on two phases) are not detected using this function. This is done by monitoring asymmetry using a suitable selection of thresholds. 103233_en_01 PHOENIX CONTACT 7 EMD-FL-3V-690 Asymmetry Monitoring If the asymmetry of the linked voltages exceeds the value set at the "ASYM" controller, the set response delay (DELAY) starts (red "ASYM" LED flashes). After the delay time has elapsed (red "ASYM" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). If a neutral conductor is connected, the asymmetry between the phase voltages (star voltage) and neutral conductor is also monitored. In this case both asymmetry values are used for evaluation. As soon as one of the two values exceeds the value set at the "ASYM" controller, the response delay starts (red "ASYM" LED flashes). After the delay time has elapsed (red "ASYM" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). Neutral Conductor Break Monitoring Using Asymmetry Monitoring A neutral conductor break between the system and supply network is detected as an asymmetry between the phase voltages and the neutral conductor, and the response delay (DELAY) starts (red "ASYM" LED flashes). After the delay time has elapsed (red "ASYM" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). A neutral conductor break between this monitoring module and the monitored system cannot be detected. 103233_en_01 PHOENIX CONTACT GmbH & Co.
