Connect or disconnect the fibers to or from the E3X amplifier using the following procedures: Screw-mounting Model 1. Connection Spring mounting clip Lever lock Toothed washers Insertion mark Fiber Nuts (attachment) Insert the fibers into the E3X amplifier and press the lever lock until the amplifier clicks to lock the fibers. The fibers will have insertion marks when they are cut with the E39-F4 (Fiber Cutter). The portion from the tips to the insertion mark should be inserted to the E3X. Column Model Retaining screw (M 3 max.) Clamping torque 3 kgf • cm max. 2. Disconnection Raise the lock lever to unlock the fibers before pulling them out. Fiber Insertion Fiber units 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. Clamping torque M3/M4 screw 8 kgf • cm max. (0.78 N • m) M6 screw 10 kgf • cm max. (0.98 N • m) 2-mm dia. column 3 kgf • cm max. (0.29 N • m) 3-mm dia. column 3 kgf • cm max.

(0.78 N • m) Locked Use a proper-sized spanner. 16 16 Unlocked E3X E3X Connection ■ AMPLIFIER UNITS Do not pull or press the Fiber Units. The Fiber Units have a withstand force of 1 kg or 3 kg (pay utmost attention because the fibers are thin). Mounting 1. Do not bend the Fiber Units beyond the permissible bending radius. 2. Mount the front part on the mounting bracket (sold together) or a DIN rail. Press the back part onto the mounting bracket or the DIN rail. Do not bend the edge of the Fiber Units. 40 mm max. Correct Amplifier Fiber unit Din rail Removal By pulling back the lock (yellow) on the bottom with a flat blade screwdriver, the amplifier can be removed with ease. 20 mm max. Incorrect 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. Do not apply excess force on the Fiber Units. Correct Fiber unit Nylon wireholder Washers (6 dia. max.) Others When power is off: The moment power is turned off, the E3X 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 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. Metal holder Incorrect The Fiber Head could be broken by excessive vibration. To prevent this, the following is effective: If power is supplied to a photoelectric sensor through a cord that is wired together with other power lines in the same duct, the cord will be influenced by the power lines and malfunctioning of the photoelectric sensor or damage could result. Wire the cord separately or use a sealed cord to supply power to the photoelectric sensor. A one-turn loop can absorb vibrations If the case of the cord is extended, use a wire with 0.3 mm2 max.. The total length of the cord should be 100 m max. Tape Power line 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 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 use a hammer to hit the amplifier when mounting or the amplifier will loose watertightness. 17 17 E3X E3X OMRON ELECTRONICS LLC OMRON ON-LINE OMRON CANADA, INC.
