Precautions for Correct Use Mounting LED Lamp • Always make sure that the power is turned OFF before mounting, • A current-limiting resistor for the LED lamp is built in, so no external resistor is required. removing, or wiring the Switch, or performing maintenance. Electric shock or fire may occur. Rated voltage Built-in limiting resistance Wiring 5 VDC 39 Ω • For wiring, use a wire size that is appropriate for the applied voltage 12 VDC 270 Ω and the supplied current. Be sure to perform soldering according to 24 VDC 1300 Ω the following conditions. Using the Switch with incomplete soldering Incandescent Lamp may result in errors and heat, which may cause fire. • It is advantageous in terms of service life and heat generation to (1) Manual soldering: Use a soldering iron with a tip temperature of apply 80% of the rated voltage (operating voltage) to the 350°C maximum and complete soldering within 3 seconds. incandescent lamp. (2) Dip soldering: Solder at 350°C for 3 s or less. Operation Wait for one minute after soldering before exerting any external force on the solder. • Always mount the Operation Unit before operating the Switch. • Use non-corrosive liquid rosin as the flux. (Using your fingers or tweezers to operate moving parts of the Switch may deform internal parts and cause malfunctions.) • If screw-tightened terminals are used, hold the Socket Unit Set or Character Film Socket Unit and install the lead wiring applying a torque of less than 0.98 N·m to the Socket Unit. Applying a torque of more than 0.98 • If the character film is to be specially prepared, use heat-resistant film with a maximum thickness of 0.2 mm. N·m may result in damage. The tightening torque is 0.59 to 0.78 N·m. A3SJ A3SA • Make sure that the insulating sheath of the wires does not come in 18.2 11.3 ±0.2 ±0.2 contact with the Unit. If wiring is performed with the insulating sheath of the wires coming in contact with the Unit, use wire with a 11.3 ±0.2 11.3±0.2 minimum heat resistance of 100°C. • After wiring the Switch, make sure that there is a suitable isolation Others distance. • If the panel is to be finished (e.g., coated), make sure that the panel Operating Environment meets the specified dimensions after the coating. • Do not use in locations that are subject to dust, oil, or metal fillings, because these may penetrate the interior the Switch and cause malfunction. Using Microloads • Using a standard load switch when a microload circuit is opened or closed may cause wear on the contacts. Use the switch within the operating range. (Refer to the diagram below.) Even when using microload models within the operating range shown below, if inrush current occurs when the contacts are opened or closed, it may cause the contact surface to become rough, and so decrease life expectancy. Therefore, insert a contact protection circuit where necessary. The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% (λ 60) (conforming to JIS C5003). −6 The equation λ 60 = 0.5 x 10 /time indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%. 0.15 mA 26 mA 100 mA 30 24 Standard Microload area load area 12 Invalid area 5 1 mA 100 mA 160 mA 0 0.1 1 10 100 1,000 Current (mA) 18 Voltage (V) A3S Application Replacing Incandescent and LED Lamps and Panel Mounting Removing the Display Barrier Mounting • Grasp the groove on the color cap surface, and pull it firmly toward • Place the Edge Barrier on the side of the Socket Unit, and then you to remove the Display. insert it into the panel. • An Extractor (A3PJ-5080) is available to conveniently remove the • Insert the Intermediate Barrier between the Switches after inserting Display. the Socket Units into the panel.
