In both cases, the E3X-NH/NHB may be damaged. otherwise the E3X-NH/NHB may be damaged. Do not short-circuit the load connected to the E3X-NH/NHB, otherwise the E3X-NH/NHB may be damaged. Fiber Unit Tightening Force Fiber Connection and Disconnection The tightening force applied to the Fiber Unit should be as follows: The E3X-NH/NHB Amplifier has a lock button. Connect or disconnect the fibers to or from the E3X-NH/NHB Amplifier using the following procedures: 1.

After cutting the fiber using the E39-F4 Fiber Cutter, put an insertion mark on the fiber as a guide for correct insertion into the Amplifier, and then insert the fiber up to this mark. 2. Disconnection Remove the protective cover and raise the lock lever to pull off the fiber. (Before removing the fiber, be sure to confirm that the lock is released so as to maintain the fiber properties.) Protective cover Unlocked Locked 3. The fiber must be locked or released in a temperature range of –10°C to 40°C. E3X-NH E3X-NH Fiber Insertion If the portion from the tip to the insertion mark of the fibers are not inserted into the Amplifier Unit, the sensing distance will be reduced. Use either one of the two holes on the right (refer to the following figure) to cut a thin fiber as follows: 1. An attachment is temporarily fitted to a thin fiber before shipment. 2.2-mm-dia. Fiber Thin fiber attachment (E39-F9) Insert to the portion from the tip to the insertion mark of each fiber into the Amplifier Unit. Amplifier Unit Temporarily fitted 2. Secure the attachment after adjusting the position of it in the direction indicated by the arrow. Fiber Unit 12.6 mm Thin Fiber with the E39-F9 Attachment Amplifier Unit The portion from the tip to the insertion mark of each fiber into the Amplifier Unit. 3. Insert the fiber into the E39-F4 to cut. Fiber Unit Cutter E39-F4 Two holes for thin fiber 12.6 mm Fiber with Fixed Length The portion from the tip to the insertion mark of each fiber into the Amplifier Unit. Amplifier Unit Three holes for standard fiber (2.2-mm dia.) 4. Finished state (proper cutting state) 12.6 mm Approx. 0.5 mm Cutting Fiber Insert a fiber into the Fiber Cutter and determine the length of the fiber to be cut. Press down the Fiber Cutter in a single stroke to cut the fiber. An insertion mark can be placed on the fiber to serve as a reference when inserting the fiber into the Amplifier. Use the following procedure. Confirm through the Cutter hole that the fiber is inserted beyond the insertion mark hole so that the insertion mark is properly indicated, and then press firmly down on the Cutter. Note: Insert the fiber in the direction indicated by the arrow. Connection Do not pull or press the Fiber Units. The Fiber Units have a withstand force of 9.8 N (1 kgf) or 29.4 N (3 kgf) (pay utmost attention because the fibers are thin). Do not bend the Fiber Units beyond the permissible bending radius. Do not bend the edge of the Fiber Units (excluding the E32-TjR and E32-DjR). (2) 20 mm min. Correct (1) Amplifier Unit Insert the fiber into the Amplifier up to the insertion mark. Proper fiber performance will not be achieved unless the fiber is inserted all the way to the insertion mark. (This method is applicable to standard, 2.2-mm-diameter fibers only.) 12.6 Fiber Unit 20 mm min. Incorrect Insertion mark 2.2-dia. The cutting holes cannot be used twice. If the same hole is used twice, the cutting face of the fiber will be rough and the sensing distance will be reduced. Always use an unused hole. 35 E3X-NH E3X-NH Do not apply excess force on the Fiber Units. Fiber Unit Nylon wireholder Correct Metal holder Incorrect The Fiber Head could be break by excessive vibration. To prevent this, the following is effective: Bending Radius E39-F11 Sleeve Bender The bending radius of the stainless tube should be as large as possible. The smaller the bending radius becomes, the shorter the sensing distance will be. Insert the tip of the stainless tube to the Sleeve Bender and bend the stainless tube slowly along the curve of the Sleeve Bender (refer to the figure). 1.2 dia. 1.2 dia. 1.3 dia. max. max. min.

Mount the front part on the mounting bracket (attachment) or a DIN track. 2. Press the back part onto the mounting bracket or the DIN track. Note: Do not mount the back part onto the mounting bracket or the DIN track first and then mount the front part on the mounting bracket or the DIN track, or the mounting strength of the Amplifier Unit may decrease. Dismounting By pressing the Amplifier Unit in direction (3) and lifting the fiber insertion part in direction “4” as shown in the following, the Amplifier can be dismounted with ease. (4) DIN track (3) (2) (1) DIN track In the case of side mounting, attach the mounting bracket on the Amplifier first, and secure the Amplifier with M3 screws and washers. The diameter of the washers should be 6 mm max. Washers (6 dia. max.) 36 E3X-NH E3X-NH Turning the Power ON After the E3X-NH/NHB is turned ON, the E3X-NH/NHB will be ready to operate in 100 ms maximum. If power is supplied to the E3X-NH and the load is connected to the E3X-NH/NHB independently, be sure to turn ON the power supply connected to the E3X-NH/NHB first. When the power is turned ON, the operation indicator will be ON momentarily. Note that this will not have an effect on performance since no control output will be generated. Mutual Interference Protection Function Perform two-point teaching if two to three Fiber Units are closely mounted together, at which time supply power only to the Unit in teaching operation in turn or block the emitters of the Fiber Units not in teaching operation. EEPROM Writing Error Write errors may result at the time of teaching due to power failure or static noise, in which case the Unit beeps and the operation indicators flash. If any of these occur, re-input teaching using the teaching button on the Amplifier. Minute Sensing Object This datasheet shows typical examples for detecting minute objects. These typical examples are for reference use only, because these example operations were tested on Units sampled at random from a lot and the values described are average values. Do not assume that all Units ensure such operations. Others When the power is OFF: The moment power is turned OFF, the E3X-NH/NHB may output a pulse signal which could affect the operation of the devices connected to it. This will occur more often if power is supplied to the E3X-NH from an external power supply, thus affecting the connected timer and counter. Use a built-in power supply as much as possible to avoid this. In a case where the cord is extended, use a wire with 0.3 mm2 min. The total length of the cord should be 100 m max. Power supply: If a standard switching regulator is used as a power supply, the frame ground (FG) terminal and the ground (G) terminal must be grounded, or otherwise the E3X-NH can malfunction influenced by the switching noise of the power supply. The supplied voltage must be within the rated voltage range. Unregulated full- or half-wave rectifiers must not be used as power supplies. Do not lay wiring to the Optical Sensor together with power lines in the same piping or ducts. Doing so will cause induction between the lines, possibly resulting in faulty operation or destruction. Always lay wiring to the Optical Sensor in separate or dedicated piping. Power line Attachment Units Applications E39-F10 Fiber Connector Use the following procedure (refer to the figure) to connect fibers via the Fiber Connector. Protective Spiral Tube Insert a fiber to the Protective Spiral Tube from the head connector side (screwed) of the tube. Splice Retention unit Protective spiral tube Fiber Unit Retention unit Push the fiber into the Protective Spiral Tube. The tube should be straight so that the fiber is not twisted when inserted. Then turn the end cap of the spiral tube. Fiber Unit Each Fiber Unit should be as close as possible before they are connected. Sensing distance will be reduced by approximately 25% when fibers are connected. Only fibers with a 2.2-mm dia. can be connected. (Refer to page 9 for applicable Fiber Units.) Protective spiral tube Fiber Unit Secure the Protective Spiral Tube on a suitable place with the attached nut. Mounting panel Hexagon clamping nut Fiber Unit Protective spiral tube Toothed washer 37 E3X-NH E3X-NH Use the attached saddle to secure the end cap of the Protective Spiral Tube. To secure the Protective Spiral Tube at a position other than the end cap, apply tape to the tube so that the portion becomes thicker in diameter. Saddle Tube End cap Reflector Observe the Following Precautions when Using the Reflector (E39-R3) Use detergent, etc., to remove any dust or oil from the surfaces where tape is applied. Adhesive tape will not be attached properly if oil or dust remains on the surface. The E39-R3 cannot be used in places where it is exposed to oil or chemicals. 38 !
