(One rubber washer will be provided when one Legend Plate Frame is ordered.) 25 (0.98) Align the Lock Fitting with the groove in the casing, then insert the Lock Fitting so that its edge is located on the panel side. For 25 mm-dia. holes, always use 25 mm-dia. Rings. (Since the cutout dimensions are large, IP65 cannot be guaranteed unless 25-dia. Rings are used.) Tighten the mounting nut at a torque of 0.98 to 1.96 N * m {10 to 20 kgf * cm}. When using a Lock Ring, replace with the supplied Lock Fitting, insert the projecting part into the lock slot, and then tighten the mounting nut. If outer surface treatment such as paint is applied to the panel, the panel dimensions after outer surface treatment must meet the specified panel dimensions.

Grip the indicator with your fingers, then rotate the indicator while pressing it against the Switch Unit. Plate spring Mounting the Color Lens: Mount the Color Lens on the flange and firmly push the Color Lens. When the Color Lens is inserted, check whether it operates properly. When replacing the Lamp, remove the Color Lens and diffusion plate with fingers or Lens Puller. Attach the Character Film properly so that it fits inside the protruding part of the diffusion plate. Then, match the diffusion plate to the square flange and insert the Lens. J CONTROL BOX (ENCLOSURE) Mounting the Switch The Standard-size Legend Plate Frame can be mounted. Mount the Frame as shown in the following diagram. Mount the Switch in the same way as for an ordinary panel. Flange Snap-in Legend Plate Diffusion plate Character Film Color Lens J EMERGENCY STOP SWITCH J INSTALLING/REMOVING THE SWITCH UNIT Insert the protrusion of the Tightening Wrench (A22Z-3905) into the Cap slot and then turn to remove the Cap. Installing the Switch Unit Hook the small protrusion on the Switch Unit into the groove on the other side of the lever, then push up the Switch Unit in the direction indicated by the arrow in the figure below. Lever Mounting Latch J INSTALLING/REPLACING THE LAMP Installing from the Panel Surface Insert the Lamp Extractor (A22Z-3901) into the lamp, then rotate the Extractor while pressing it. Protrusion Switch Unit 45 All A22/M22 Assemblies All A22/M22 Assemblies Removing the Switch Unit J ENGRAVING Insert a screwdriver between the Mounting Latch and the Switch Unit, then push down the screwdriver in the direction indicated by the arrow in the following figure. Engrave the characters on the surface on the Cap. Make sure that the characters are aligned parallel to the imaginary line connecting the two protruding portions to the left and right of the Cap. Use either of the following screwdrivers. Flat-head screwdriver The characters must not be engraved deeper than 0.5 mm. Apply an alcohol-based paint coating, such as melamine, alkyd, or acrylic resin paint coating, to the engraved characters. Phillips screwdriver Protruding portions on Cap J AFFIXING CHARACTER FILM Screwdriver Hold the Cap, remove the cardboard on the Film, and attach the Film to the Cap. Make sure that the protruding portions of the Cap engage the cutout portions of the Film and that the characters are aligned parallel to the imaginary line connecting the two protruding portions to the left and right of the Cap. J WIRING Wiring Round Crimp Terminals Remove the cardboard. Loosen the terminal screw from the Switch Unit until it completely comes off the groove, insert a screwdriver as shown in the following figure, then push up the washer in the direction indicated by the arrow to temporarily secure it. Now, a round crimp terminal can be connected. After inserting the terminal, tighten the screws to complete wiring. Protruding portions on Cap J MOUNTING AND DISMOUNTING SNAP-IN LEGEND Washer Press and secure the Snap-in Legend Plate onto the Legend Plate Frame. Screw The direction of the characters will vary with the mounting direction of the control panel if the Switch is a knob or key selector model. Screwdriver Legend Plate Frame Snap-in Legend Plate Concave surface 46 All A22/M22 Assemblies All A22/M22 Assemblies To easily remove the Snap-in Legend Plate from the Legend Plate Frame mounted to the panel, insert a Tool with a thin tip into the space between the Snap-in Legend Plate and the Legend Plate Frame. J ENGRAVING METHOD Material: Acrylic Engrave the characters directly on the matted side of the Snap-in Legend Plate. The characters must be engraved no deeper than 0.5 mm. Apply alcohol-based paint coating to the engraved characters. If the Snap-in Legend Plate is transparent, engrave the mirror-written characters on the back of the Snap-in Legend Plate and apply paint coating to the characters. Then apply paint coating of a different color to the remaining part of the Snap-in Legend Plate. J MOUNTING THREE-THROW SPACER Press and secure the two protruding portions of the Three-throw Spacer to the two indented portions of the inner side of the control panel. The Snap-in Legend Plate is easily removed by pressing the Snap-in Legend Plate from the back of the Legend Plate Frame. The Legend Plate Frame is made of acrylic resin, which is easily damaged by shock. Be sure to handle the Legend Plate Frame with care. Precautions ! WARNING Wiring After wiring the Switch, maintain an appropriate clearance and creepage distance. Do not apply a voltage between the incandescent lamp and the terminal that is greater than the rated voltage. If the incandescent lamp is broken, the Operational Units may pop out. Always turn OFF the power and wait for 10 minutes before replacing the incandescent lamp. If the lamp is replaced immediately after the power is turned OFF, the remaining heat may cause burns. When DC-specific LEDs are used, wire the Switch so that the X1 terminal is positive. Terminal screws must be Phillips or slotted M3.5 screws with a square washer. The tightening torque is 1.08 to 1.27 N * m {11 to 13 kgf * cm}. J CORRECT USE Single wires, stranded wires, and crimp terminals can be connected to the Switch. Mounting Operating Environment Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. The IP65 model is designed with a protective structure so that it will not sustain damage if it is subjected to water from any direction to the front of the panel. Do not tighten the mounting ring more than necessary using tools such as pointed-nose pliers. Doing so will damage the mounting ring. The tightening torque is 0.98 to 1.96 N * m {10 to 20 kgf * cm}. The panel thickness is 1 to 5 mm. 47 All A22/M22 Assemblies All A22/M22 Assemblies Using the Microload Others Insert a contact protection circuit, if necessary, to prevent the reduction of life expectancy due to extreme wear on the contacts caused by loads where inrush current occurs when the contact is opened and closed. The oil-resistant IP65 uses NBR rubber and is resistant to general cutting oil and cooling oil. Some particular oils cannot be used with the oil-resistant IP65, however, so contact your OMRON representative for details. The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% ( 60) (conforming to JIS C5003). If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after the coating. The equation, 60 = 0.5 x 10--4/time indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%. Do not subject the Switch to extreme shock or vibration. Doing so will cause malfunctions and damage to the Switch. Do not let sharp objects come into contact with the Switches that are made of resin. Doing so will damage the Switches, causing scratches on the outside of the Operational Units, and malfunction. When handling the Switches, do not throw or drop them. Voltage (V) Area of use General-purpose load area Do not allow the Switch to drop and hit the ground. Microload area Invalid area Current (mA) LEDs The LED current-limiting resistor is built-in, so internal resistance is not required. If commercially available LEDs are used, select the ones that meet the following conditions: Do not place or drop heavy objects on the Switch. Base: BA9S/13j Overall length: 26 mm max. Power consumption: 2.6 W max. Do not operate the Switch with hard or sharp objects. Hammer Screwdriver NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.
