LZB Series Mounting and Moving Auto Switches (Series LDZB Only) Caution 1. Tighten the screw under the specified torque when mounting the auto switch. 2. Set the auto switch mounting band perpendicularly to cylinder tube. Correctly attached Incorrectly attached Mounting the Auto Switch 1. Attach a switch bracket to the switch holder. (Fit the switch bracket to the switch holder.) 2. Mount an auto switch mounting band to the cylinder tube. 3. Set the switch holder (1.) between the reinforcing plates of the band mounted to the cylinder. 4. Insert an auto switch mounting screw in the hole of the reinforcing plate through the auto switch holder, and thread it into the other plate. Tighten the screw temporarily. 5. Remove the set screw attached to the auto switch. 6. Attach a switch spacer to the auto switch. 7. Insert the auto switch with the switch spacer from the back of the switch holder. (Insert the auto switch with an angle of approximately to 15. See figure 1.) 8. To secure the auto switch, tighten the switch mounting screw with the specified torque (0.8 N m to 1.0 N m). Adjusting the Auto Switch Position 1. Unloosen the auto switch mounting screw 3 turns to adjust the auto switch set position. 2. Tighten the auto switch mounting screw as described above (8.) after adjustment. Removing the Auto Switch 1. Remove the auto switch mounting screw from the switch holder. 2. Move the auto switch back towards the position where it stops at the lead wire side. 3. Hold up the lead wire side of the auto switch at the angle of around 45. 4. Maintain the angle, and pull back the auto switch obliquely at the same angle.

When two auto switches are connected in series, a load may malfunction because the load voltage will decline when in the ON state. The indicator lights will light up when both of the auto switches are in the ON state. es with load voltage less than V cannot be used. Load voltage at ON = Power supply voltage Residual voltage x 2 pcs. = 24 V 4 V x 2 pcs. = 16 V Example: Power supply is 24 VDC Internal voltage drop in auto switch is 4 V. Load 3-wire OR connection for NPN output 1 2 Load 3-wire OR connection for PNP output 1 2 (Solid state) When two auto switches are connected in parallel, malfunction may occur because the load voltage will increase when in the OFF state. Load voltage at OFF = Leakage current x 2 pcs. x Load impedance = 1 ma x 2 pcs. x 3 kω = 6 V Example: Load impedance is 3 kω. Leakage current from auto switch is 1 ma. Load (Reed) Because there is no current leakage, the load voltage will not increase when turned OFF. However, depending on the number of auto switches in the ON state, the indicator lights may sometimes grow dim or not light up, due to the dispersion and reduction of the current flowing to the auto switches. 943

LZB Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 50 for Safety Instructions and pages 3 to 13 for Electric Actuators/Cylinders and Auto Switches Precautions. Caution 1. Mount the auto switches at the center of the operating range. Check ON and OFF points before setting auto switches so that positions can be detected at the center of the operating range. If mounted at the end of the operating range, the signal detection will be unstable. 2. Be aware of the environment temperature and thermal cycle. Operate auto switches and auto switch cylinders within the operating temperature range. The reliability of the auto switches may be adversely affected, especially, when they are exposed to thermal shock, severe temperature and humidity cycle etc. 3. Be aware of the suitability of oil, chemicals etc. Resin and rubber materials are used for the auto switches and auto switch mounting brackets. Therefore, if there are chemicals such as oil or organic solvents in the environment, the resin and rubber materials may be adversely affected. 4. During maintenance, securely tighten the switch mounting screws periodically. Use auto switch mounting brackets with the proper tightening torque. In addition, securely tighten the auto switch mounting screws periodically. 5. Be careful not to pull or strain the lead wires. Be careful not to apply excess tensile force (over N) to the auto switches. Also, adjust the position of the auto switches by sufficiently loosening the auto switch mounting screws (3 turns or more). 6. Do not use the auto switches in environments with strong vibration and impact. Do not use the auto switches in environments where excess vibration and impact force outside of the specifications are applied. 7. Be sure to use a switch spacer and a switch bracket. Confirm that a switch spacer is mounted to the end of the auto switch before fastening the auto switch. If the switch bracket is not mounted, the auto switch may move after installation. 945
