The ECS7 Series is availablein solid or split core housing styles.The ECS7 Series magnetically isolated solid state output contacts arerated for 0.30A @ 135V AC/DC. This “universal” output makes thisproduct especially well suited for PLC control systems or a variety ofload connections.Eaton’s current sensor family encompasses a broad range of productsfor cost-effective monitoring, status, and predictive maintenance.Downtime and costly repairs can be avoided by utilizing Eaton’sproducts and technology in your control systems.Note: Unless otherwise specified, the term “load” refers to thecurrent being monitored.Installation InstructionsCurrentWatch™ ECS7 Series Current SwitchesSelf-Calibrating AC Current Switch with Solid State OutputsINSTALLATIONConsiderations for all ECS7 Series models…• Run wire to be monitored through the aperture (opening) in theswitch body.• These switches can be located in the same environment asmotors, contactors, heaters, pull-boxes and other electricalenclosures.• Mounting can be done in any position or hung directly on a wirewith a wire tie.• Be sure to leave at least one inch distance between sensor andother magnetic devices.Considerations for split-core models only…• Press the tab in the directionshown in the diagram to the right.• After placing the wire in theaperture, press the hinged portionfi rmly downward until a click isheard and the tab pops out fully.• Keep split-core contact areasclean. Silicon grease is factory applied on the mating surfaces toprevent rust and improve performance. Be careful not to allowgrit or dirt into the grease in the contact area, particularly on coremating surfaces of split core models. Sensor operation could beimpaired if mating surfaces do not have good contact. Checkvisually before closing.QUICK INSTALL GUIDEThe below steps can be followed to quickly install a CurrentWatch™ECS7 Series switch.1. Run the wire to be monitored through the aperture2. Mount the sensor3. Connect output wire to the solid state relay terminalsa. Use up to 14 AWG copper wiresb. Don’t exceed output rating4. Slide the Function Switch from “CLR” to “RUN”5. Turn load “on”, equipment is now energized and sensor iscalibrated• Note: Refer to the LED Indication table on page two for switchoperation.WIRING DIAGRAMConnect control or monitoring wires to the sensor. Use up to 14 AWGcopper wire and tighten terminals to 7 inch-pounds torque. Be sure theoutput load does not exceed the solid state output rating.CAUTION! Incandescent lamps can have “cold filament inrush”current of up to ten times their rated amperage. Use caution whenswitching lamps.P51922 Rev 04Effective: April 2010 Page 1WARNINGQuestions?
