Sensitivity setting methodMaximum sensitivity setting No-object teaching With/Without-object teaching Typical application Detection of the existence of objects that interrupt light perfectly Detection of objects with no background objects If teaching is impossible by stopping the movement of sensing objects To detect bright or dark objects by teaching only with background objects Detection of a slight difference in reflection Color discrimination Background objects with unstable reflection Detection of object surface irregularities Elimination of background object influence Note: 1. None of the four channels has any output when the E3X-NM (four channels) is in teaching mode (i.e., all the four channels will be in teaching mode). 2. If the set distance is very short (i.e., 0 to 12 mm for the E32-TC200 and 0 to 4 mm for the E32-DC200), no-object teaching is not possible due to excessive light, in which case, perform with/without-object teaching. 3. In principle, use the E3X-NM (four channels) for the close connection of a maximum of four Fiber Units. When closely connecting two to three Fiber Units to more than one E3X-NT (one channel), perform with/without-object teaching, in which case teaching must be performed on a single E3X-NT at a time. Therefore, turn on only the E3X-NT on which teaching is performed. If all the E3X-NTs are turned on, interrupt the emitters of the Fiber Units on which teaching is not performed.

Large Small Considering a drop in light value due to optical axis divergence or dust on the lenses, sample the light of the first to fifth objects. Then reset the operating level to the median value between the lowest light with a sens- ing object and the light without sensing object. Resetting Operating level Light With Reflective (Light-ON) Fiber Unit 1. Teaching button is pressed once. 2. The first sensing object is in the sensing area. 3. Sensing objects continue to pass through the sensing area. Operating level 10% ON OFF Large Small Operating level Set the operating level to ±10% of the light level.

Then reset the operating level to the median value between the lowest light with a sensing object and the light without a sensing object. Large Small Resetting Operating level Light Light Light Note: If the light value up to the fifth object is at least twice as large as the operating level, the initial set operat- ing level (10%) will be maintained. Change to RUN mode Note: 1. After no-object teaching, when the E3X-N is turned off and on, the operation level will be set to the +10% of the initial light level (refer to the above (1)) in reflective operation and –10% of the initial light level in through-beam operation and stand by. 2. After performing no-object teaching and changing to RUN mode, until the first sensing object is in the sensing area, the control output will be prohibited (OFF). The control output will be determined when the first sensing object is detected. 3. The initial operating level compensation function will operate after teaching and/or after the E3X-N is turned on. 4. During no-object teaching, after the E3X-N is in RUN mode, each channel requires approximately 60 ms to determine the operat- ing level from the time the first sensing object is in the sensing area. Therefore, when using the E3X-NM (four channels), set an interval of 60 ms minimum for each channel if sensing objects are forwarded in sequence to the sensing area of each channel. After the operating level is determined, the E3X-NM will operate with a normal response speed of 500 µs.

Remote Teaching/Timer Set Function Remote Teaching Function In principle, the remote teaching function of the E3X-N should be used for initial teaching. Basically, the method of remote teaching is the same as that of sensitivity setting. In remote teaching, instead of pressing the teaching button, teaching is performed with a remote teaching input signal. 1. Set the mode selector to RUN. 2. The following signal conditions must be given as remote teaching input conditions. 1. In the case of the E3X-NM, teaching is performed on all the four channels of the E3X-NM. 2. If all four channels are not used (e.g., only three channels are used), with/without-object teaching will not be available. In which case, perform the usual with/without-object teaching on the channels that are used instead of performing remote teaching. 3. If remote teaching is not performed, cut the pink wire at the base or connect the pink wire to the +V terminal. 4. After remote teaching input setting is finished, the E3X-N will be ready to detect objects in approximately one second.

Select a channel with the channel selector, at which time the stability indicator for the selected channel will flash. 3. The timer of the E3X-NM will be set by pressing the teaching button of the E3X-NM, at which time the operation indicator will be lit. When the teaching button is pressed again, the timer will be disabled and the operation indicator of the E3X-NM will be lit. To perform setting on other channels repeat procedures 2 and 3. 4. Set the mode selector to RUN. Note: Channels are selected in the following order. When all the channels are selected, it is possible to set the timer function on all channels.

Optical Axis Adjustment (Super-flashing Function) Set the mode selector of the E3X-N to TEACH. The super flashing function of E3X-N will be activated. When the optical axes of the fiber heads are divergent and the light value decreases by approximately 10% of the maximum value, the tip of the emitting fiber will start flashing and the built-in buzzer will beep. At this time, if the optical axes are divergent, adjust the axes. The peak light value will be memorized by the E3X-N . Do not press the teaching button before or while adjusting the optical axes, otherwise, the super-flashing function will not operate.

Fiber Connection and Disconnection E3X-NT/NM/NV/NVG The E3X-N Fiber Amplifier Unit adopts a snap-locking system. Con- nect or disconnect the Fiber Unit according to the following proce- dures: 1. Connection

• E3X-NT Lock lever Fiber insertion mark Fiber E3X-NT Remove the protection cover, in- sert the fiber into the Unit, and then lower the lock lever until a click sound is heard.
• E3X-NM Lock button After inserting the fiber into the Unit, press the lock button until a click sound is heard. This will fix the fiber. After cutting the fibers using the Fiber Cutter (E39-F4), place an in- sertion mark on the fiber so that it can be properly inserted into the Amplifier. Insert the fiber into the Amplifier up to this insertion mark. 2. Disconnection
• E3X-NT Remove the protective cover, raise the lock lever, and then pull out the fiber.
• E3X-NM Press the lock button again. The lock will be released and the button will pop up. Pull out the fiber. Do not forcibly pull up the lock button. (Be sure to pull out the fiber only after confirming that the lock has been released in order to maintain the fiber characteristics.) E3X-NT Protective cover Unlocked Locked E3X-NM UnlockedLocked E3X-NV/NVG Protective cover UnlockedLocked 3. Precaution When Connecting or Disconnecting Fibers Lock the fiber or release its lock under an ambient temperature range between –10°C and 40°C. 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 proce- dure. 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. 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.)

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.

To prevent this, the following is effective: 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 sleeve to the Sleeve Bender and bend the stainless sleeve slowly along the curve of the Sleeve Bender (re- fer to the figure).

Handling E32-D51/-T51 Heat-resistive Fiber The bending radius of the fibers should be 35 mm min. Connecting fibers via the E39-F10 Fiber Connector is not possible. The withstand temperature of the Heat-resistive Fibers is 150°C max. In continuous operation, the ambient temperature should be 130°C max.

Seal E32-L25 (A) Wafer Sensor Insert the fiber with a white line into the light emission side of the Amplifier. The tightening force of the sensor head is 8 kgf /C0083 cm max. (0.75 N /C0083 m). Avoid places where water could be sprayed onto the E32-L25(A). E32-T16/-T16P Slit Seal (Attachment) Peel the E32-T16 Slit Seal off the ground paper and affix the Slit Seal to the sensing face of the Sensor so that the corners of the Slit Seal fit in with the corners of the sensing face. To detect an object at a distance of 45 cm max., a 0.5-mm wide Slit Seal must be used. E32-T16 Sensing Head Attachment slit E32-M21 The four fibers must be separated so that there will be no mutual in- terference.

The diameter of the washers should be 6 mm max. Washers (6 dia. max.) E3X-NT Turning Power On After the E3X-N is turned on, the E3X-N will be ready to operate in 100 ms maximum. If power is supplied to the E3X-N and the load is connected to the E3X-N independently, be sure to turn on the power supply connected to the E3X-N first. Output Short-circuit Protection When the E3X-N is turned on or off, no control output will be ON, even though the operation indicator of the E3X-N will be lit for an instant. If the short-circuit protection function of the E3X-NM (four channels) is activated, none of the four channels will have any out- put. Unused Channels of E3X-NM (Four Channels) Unused channel protection seals are provided with the E3X-NM. If all the four channels are not used (e.g., if only three channels are used), paste an unused channel protection seal to the fiber insertion hole. Mutual Interference Protection Function In principle, use the E3X-NM (four channels) for the close connec- tion of a maximum of four Fiber Units. When closely connecting two to three Fiber Units to more than one E3X-NT (one channel), perform with/without-object teaching, in which case teaching must be performed on a single E3X-NT at a time. Therefore, turn on only the E3X-NT on which teaching is per- formed. If all the E3X-NTs are turned on, interrupt the emitters of the Fiber Units on which teaching is not performed. EEPROM Writing Error Power interruptions or noise caused by static electricity or other causes can result in write errors during any part of the teaching pro- cess from teaching initial operating levels without a workpiece to fi- nal compensations. These errors include buzzers, lighting of teach- ing indicators, simultaneous flashing of read/green indicators, light- ing of operation indicators, and lighting or flashing of stability indica- tors. If any of these occur, re-input teaching using the teaching but- ton on the Amplifier. Others When power is off: The moment power is turned off, the E3X-N could output a pulse signal which could affect the operation of the devices connected to it. This will happen more often if power is supplied to the E3X-N 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 the case of 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-N 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 E3X-NT

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 2.2-mm dia. can be connected. Protective Spiral Tube Insert a fiber to the Protective Spiral Tube from the head connector side (screwed) of the tube. Fiber UnitProtective 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 washerProtective spiral tube Use the attached saddle to secure the end cap of the Protective Spi- ral 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 End cap Tube E3X-NT WARNING The E3X-N is not a safety component for ensuring the safety of people as defined in EC Directive 91/368/EEC, or as covered by separate European standards or by any other regulations or standards.
