It can be set to clockwise operation (CW) or counterclockwise (CCW) operation. Use the procedure given at the right to change the operating direction. Operating procedure 1. Remove the four Head set screws and remove the Head from the Switch Box. Head Cover Operating position mark (arrow) 2. Turn the bottom of the Head toward you, press in the Head Cover shown in the diagram at the left, and turn the Cover clockwise or counterclockwise. Note: The factory setting is for “CW.CCW.” 3. The “CW” setting is for clockwise operation and the “CCW” setting is for counterclockwise operation. Set the Cover to the desired position. Safety Precautions Be sure to read the precautions for All Safety Limit Switches in the website at:http://www.ia.omron.com/. Indication and Meaning for Safe Use Mounting Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, or undesirable effect on product performance. Use four M5 screws with washers to mount the standard model. Be sure to apply the proper torque to tighten each screw. Mounting Dimensions (M5) Standard Model Precautions for Safe Use • Do not use the Switch submerged in oil or water, or in locations continuously subject to splashes of oil or water. Doing so may result in oil or water entering the Switch interior. (The IP67 degree of protection specification for the Switch refers to water penetration while the Switch is submersed in water for a specified period of time.) • Always attach the cover after completing wiring and before using the Switch. Also, do not turn ON the Switch with the cover open. Doing so may result in electric shock. Precautions for Correct Use Appropriate Tightening Torque (3) (6) Be sure to tighten each screw of the [email protected] properly, otherwise the [email protected] may malfunction. (4) (1) 60 30 Changes in Actuator Mounting Position • To change the angle of the lever, loosen the Allen-head bolts on the side of the lever. • The operating position indicator plate * has protruding parts which engage with the lever, thus allowing changes to the lever position by 90°. • The back of the operating position indicator plate * has no protruding parts. If this plate is turned over and attached, any angle within a 360° range can be set. Do not turn over the plate, however, when using the [email protected] as a switch with a certified direct opening mechanism. For an SUVA- or BIA-certified application, make sure that the lever engages with the operating position indicator plate securely so that the lever will not slip. * The operating position indicator plate: Refer to page 5. Changes in Head Mounting Position By removing the screws on the four corners of the head, the head can be reset in any of four directions. Make sure that no foreign materials will penetrate through the head.
