a16 24 safety precautions refer to safety precautions for all pushbutton switches . 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 operating part 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. mounting ? always make sure that the power is turned off before mounting, removing, or wiring the switch, or performing maintenance. ? do not tighten the mounting nut more than necessary using tools such as pointed-nose pliers. doi ng so will damage the mounting nut. the tightening torque is 0.29 to 0.49 n m. wiring ? solder terminals and quick-connect terminals (#110) are commonly used for terminals. ? be sure to use electrical wires that are a size appropriate for the applied voltage and carry current (conductor size is 0.5 to 0.75 mm 2 ). perform soldering accordi ng to the conditions provided below. if the soldering is not proper ly performed, the lead wires will become detached, resulting in short-circuits. 1. hand soldering: 350 c, within 3 s 2. dip soldering: 350 c, within 3 s wait for one minute after solder ing before exerti ng any external force on the solder. ? use non-corrosive resin fluid as the flux. ? make sure that the electric cord is wired so that it does not touch the unit. if the electric cord touches the unit, then electric wires with a heat resistance of 100 c min. must be used. ? after wiring the switch, maintain an appropriate clearance and creepage distance. operating environment ? this switch is intended for i ndoor use only. using the switch outdoors will cause the switch to fail. if ip40 models are used in locations subject to dust, metallic particles, or oil, be careful that none of these penetrates the switch. ? the ip65 model is designed with a degree of protection so that it will not sustain damage if it is s ubjected to water from any direction to the front of the panel. ? do not use the switch submersed in oil or water, or in locations continuously subject to sp lashes of oil or water. doing so may result in oil of water entering the switch. using the microload ? insert a contact protection circui t, 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 a16 allows both a standard load (125 v at 5a, 250 v at 3 a) and a microload. if a standard lo ad is applied, however, the microload area cannot be used. if the microload area is used with a standard load, the contact surface will become rough, and the opening and closing of the contact for a microload may become unreliable. ? the minimum applicable load is the n-level reference value. this value indicates the malfunction refe rence level for the reliability level of 60% ( 60) (conforming to jis c5003). the equation, 60 = 0.5 10 -4 /operations indicates that the estimated malfunction rate is less than 1/2,000,000 operations with a reliability level of 60%. led ? the led current-limiting re sistor is built-in, so external resistance is not required. others ? the oil-resistant ip65 uses nbr rubber and is resistant to general cutting oil and cooling oil. some par ticular oils cannot be used with the oil-resistant ip65, howev er, so contact your omron representative for details. ? the durability of the switch depends in the switching conditions. always test the switch under ac tual application conditions to confirm applicability and use the switch only for the number of switching operations that will not affect performance. continuing to use the switch with degraded performance will eventually result insulation faul ts between circuits, burning of the switch, or other failures. ? if the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after the coating. ? do not subject the switch to extr eme 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 operating parts, and malfunction. when handling the switches, do not throw or drop them. warning precautions for correct use rated voltage internal limiting resistor 5 vdc red, yellow, white: 300 ? green, blue, pure white: 160 ? 12 vac/vdc red, yellow, white: 1 k ? green, blue, pure white: 910 ? 24 vac/vdc 2.4 k ? invalid area 0.1 1 10 100 1,000 1 ma 5 12 24 30 0.15 ma current (ma) voltage (v) 0 microload area
a16 25 ? rubber is used inside ip65 models. do not allow the rubber to become scratched or foreign ma tter to become attached to the rubber. scratches and foreign matter will degrade the waterproofing, and the switch may fail operate correctly. screw-less clamp wiring procedure connecting wires 1. strip the wires for 10 mm (allowable range: 10 1 mm). 2. if braided wire is used, twist the wire to straighten it out. 3. insert the wire into the insertion hole while pressing the release button at the side of the hole. (using a precision screwdriver is recommended.) 4. let go of the release button to lock the wire into place. 5. after locking, pull on the wire gently to confirm that it is securely locked. removing wires 1. remove wires by pulling them while pressing the release button. note: when reusing wires that have alr eady been locked one, cut off the end of the wire and strip the wire again before using. precautions 1. the mounting panel thickness must be 0.5 to 3.2 mm. 2. the mounting ring must be tightened to a torque 0.29 to 0.49 n m. 3. the procedure for making the m ounting hole for the screw-less clamp connector is described on page 21. a mounting dimension of at least 33 mm is required, however, because the switch is removed with the screw-less clamp connector mounted to the panel. if switches are mounted si de-by-side separated by less than the specified distance, it may not be possible to remove the switch. 4. be sure to mount the case to the switch with the correct orientation. mount with the dimple on the case facing in the same direction as the side of the switch with the direction arrow or the word top. 5. bend the end of the wire if br aided wire is used with the screw- less clamp connector. 6. when wiring, insert the wire unt il it comes into contact with something. after wiring is completed, pull on the wires to confirm that they are connected securely. 7. after wiring, ensure that continuou s pressure is not applied to the terminals. 8. refer to internal connection di agrams and confirm the terminal numbers before wiring. do not allow the switch to drop and hit the ground. do not place or drop heavy objects on the switch. do not operate the switch with hard or sharp objects. screwdriver hammer switch direction arrow case dimple switch top mark case dimple
a16 26 panel mounting after mounting the pushbutton unit (i.e., the pushbutton and the case) to the panel, snap in the switch unit (i.e., the switch and the lamp) from the back of the panel. mounting to the panel ? insert the pushbutton unit into the front of the panel, and fix the lock ring and mounting nut from the terminal side. ? make sure that the lock ring is aligned with the thread of the case and the edge of the lock ring is touching the panel. ? tighten the mounting nuts to a torque of 0.29 to 0.49 n m. mounting the switch unit ? snap on the switch unit to the pushbutton unit. ? make sure that the switch unit has the correct orientation when snapping it onto the case. align the dimple on the case with the groove between the case guards on the nc terminal side of the switch unit in the way shown below, and push the switch unit into the case until it clicks into place. confirm that the switch unit is securely in place before using. removing the switch unit ? grip the part between the switch holder of the case and the switch unit using the a16z-5080 extractor, and pull to remove the switch unit. note: refer to page 21 for pcb terminals. engraving engraving the legend plate ? the characters must not be engraved deeper than 0.4 mm. ? apply an alcohol-based paint c oating, such as melamine, phthalate, or acrylic resin paint coating. mounting and replaci ng the pushbutton removing and mounting the pushbutton (1) remove the pushbutton as shown in the following diagram. if the pushbutton cannot be removed by hand, use the a3pj-5080 extractor.
