e3x-nh e3x-nh 34 precautions be sure to heed the following precautions to fully utilize the capabilities of the e3x-nh/nhb. general do not impose any voltage exceeding the rated voltage on the e3x- nh/nhb. do not impose 100 v ac or more on models that operate with dc. in both cases, the e3x-nh/nhb may be damaged. do not short-circuit the load connected to the e3x-nh/nhb, other - wise the e3x-nh/nhb may be damaged. when supplying power to the e3x-nh/nhb, make sure that the po - larity of the power is correct, otherwise the e3x-nh/nhb may be damaged. the load must be connected to the e3x-nh/nhb in operation, otherwise the e3x-nh/nhb may be damaged. fiber unit tightening force the tightening force applied to the fiber unit should be as follows: screw-mounting model cylindrical model spring mounting clip toothed washers nuts (attachment) retaining screw (m 3 max.) clamping torque 3 kgf cm max. fiber units clamping torque m3/m4 screw 0.78 n m (8 kgf cm) m6 screw 0.98 n m (10 kgf cm) 2-mm-dia. column 0.29 n m (3 kgf cm) 3-mm-dia. column 0.29 n m (3 kgf cm) e32-d14l 0.98 n m (10 kgf cm) e32-t12f 0.78 n m (8 kgf cm) e32-d12f 0.78 n m (8 kgf cm) e32-t16 0.49 n m (5 kgf cm) e32-r21 0.59 n m (6 kgf cm) e32-m21 up to 5 mm to the tip: 0.49 n m (5 kgf cm) up to 5 mm from the tip: 0.78 n m (8 kgf cm) e32-l25a 0.78 n m (8 kgf cm) e32-t16p e32-t24s e32-l24l e32-l25l 0.29 n m (3 kgf cm) use a proper-sized spanner . fiber connection and disconnection the e3x-nh/nhb amplifier has a lock button. connect or discon - nect the fibers to or from the e3x-nh/nhb amplifier using the fol - lowing procedures: 1. connection lock button fiber fiber insertion mark remove the protective cover , insert the fiber into the amplifier , and lower the lock button until a click is heard. 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.

(2) (1) insert the fiber into the amplifier up to the insertion mark. proper fi - ber performance will not be achieved unless the fiber is inserted all the way to the insertion mark. (this method is applicable to stan- dard, 2.2-mm-diameter fibers only .) 12.6 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 dis - tance will be reduced. always use an unused hole. 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. temporarily fitted thin fiber attachment (e39-f9) 2. secure the attachment after adjusting the position of it in the direction indicated by the arrow . 3. insert the fiber into the e39-f4 to cut. three holes for standard fiber (2.2-mm dia.) cutter e39-f4 two holes for thin fiber 4. finished state (proper cutting state) approx. 0.5 mm 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 with- stand 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-t r and e32-d r). correct incorrect 20 mm min. amplifier unit fiber unit 20 mm min.
e3x-nh e3x-nh 36 do not apply excess force on the fiber units. fiber unit nylon wireholder correct incorrect metal holder the fiber head could be break by excessive vibration. t o prevent this, the following is ef fective: a one-turn loop can absorb vibrations. tape bending radius e39-f11 sleeve bender the bending radius of the stainless tube should be as large as pos - sible. 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). fiber tip position mark do not bend here. 1.2 dia. max. 1.3 dia. min. 1.2 dia. max. r 12.5 r 7.5 r 10 r 5 stainless tube 90 o max. 10 10 amplifier units mounting mounting 1. 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. (1) (2) din track dismounting by pressing the amplifier unit in direction (3) and lifting the fiber in - sertion part in direction a4o as shown in the following, the amplifier can be dismounted with ease.

e3x-nh e3x-nh 37 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 indica - tors 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 ob- jects. 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 con- nected to it. this will occur more often if power is supplied to the e3x-nh from an external power supply, thus affecting the con- nected 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 mm 2 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. unreg - ulated full- or half-wave rectifiers must not be used as power sup- plies. 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 . splice retention unit retention unit fiber unit each fiber unit should be as close as possible before they are con - nected. 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 t ube insert a fiber to the protective spiral t ube from the head connector side (screwed) of the tube. fiber unit protective spiral tube 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. protective spiral tube fiber unit secure the protective spiral tube on a suitable place with the at- tached nut. mounting panel hexagon clamping nut fiber unit toothed washer protective spiral tube
