Failure to turn power off may cause electrical shocks or fire hazard. • To avoid burning your hand, use the lamp holder tool when replacing lamps. • For wiring, use wires of a proper gauge to meet the voltage and current requirements. Failure to tighten terminal screws may cause overheating and create a fire hazard. Operating Instructions Replacement of Lens and Marking Plate Wiring • Removal Solder the terminal at 350°C within 3 seconds using a 60W soldering iron. Sn-Ag-Cu type is recommended when using leadfree solder. When soldering, do not touch the control unit with the soldering iron. Also ensure that no tensile force is applied to the terminal. Do not bend the terminal or apply excessive force to the terminal. Use non-corrosive rosin flux. Remove the lens assembly (color lens, marking plate, lens holder, and spring) by holding the color lens recesses with the Lens Removal Tool (MT-101) and pulling it out. Remove the marking plate by disengaging the latches between the color lens and lens holder. The marking plate must be engraved on the front side as shown below. Latches Installing the Socket Install the socket on the control unit with the TOP markings on the control unit and the socket placed in the same direction. Engraving Area Color Lens Marking Plate Operating Voltage of LED Lamps Lens Holder • Installation Place the marking plate on the lens holder in the correct direction, and press the color lens onto the lens holder to engage the latches. Put the spring on the lens holder and insert the lens holder into the housing in the correct direction. • Installing Non-illuminated Button Non-illuminated pushbuttons contain a marking plate like illuminated units. Be sure to install the marking plate when replacing the button. Replacing the LED Lamp • Removal Use the lamp holder tool (OR-66) to remove lamps. Do not use pliers. • Installation Use the lamp holder tool (OR-66) to install lamps. Note the correct side of the tool for removal or installation. Lamp Holder Tool OR-66 (ø8, ø10, ø12 series) For removing lamps For installing lamps The operating voltage is measured at complete DC. When using a pulsating voltage such as a full-wave rectification voltage, keep peak currents within the forward current If. Peak currents exceeding the If may shorten the LED lamp life. Other Notes • Close Proximity Mounting When mounting pilot lights or illuminated pushbuttons collectively or lighting them continuously, heat may cause the ambient temperature to rise above the rated operating temperature. When the mounting panel is not made of metal or when the control units are mounted in an enclosed panel, provide for ventilation or lower the operating voltage. • Replacement of Buttons (Illuminated/Non-illuminated) Do not replace buttons of maintained action units while the button is in the locked position. Replacing the button in the locked position may damage the internal mechanism. Be sure to release the button before replacing. • Operating and Storage Environment 1. Make sure that the operating/storage temperature and humidity are within the ratings. 2. Do not use enclosed type units (IP40) in an environment subject to oil, water or dust accumulation. In such an area, use the waterproof/oiltight units (IP65). • Microswitch Contacts Do not connect NO and NC contacts of the microswitch to different voltages or different power sources to prevent a dead short-circuit. Panel Mounting • IP65 Type Units When mounting the control units onto a panel, use the optional locking ring wrench (MT-002) to tighten the locking ring. Do not use pliers. Tightening torque must not exceed 0.78 N·m. Excessive tightening will damage the locking ring. IP65 type units are evaluated by conventional cutting and cooling oils, and can not be used with some special oils. Contact IDEC for resistance against special oils. 30 (06/11/10) A1 Series Miniature Control Units ø10 Short 22-mm-long body miniature control unit series with LED illumination face and snap-action switching. • • • • Bright and clear LED illumination. 10-mm mounting holes All series have terminals on the same plane.

Failure to turn power off may cause electrical shocks or fire hazard. • To avoid burning your hand, use the lamp holder tool when replacing lamps. • For wiring, use wires of a proper gauge to meet the voltage and current requirements. Failure to tighten terminal screws may cause overheating and create a fire hazard. Operating Instructions Replacement of Lens and Marking Plate Wiring • Removal Solder the terminal at 350°C within 3 seconds using a 60W soldering iron. Sn-Ag-Cu type is recommended when using leadfree solder. When soldering, do not touch the control unit with the soldering iron. Also ensure that no tensile force is applied to the terminal. Do not bend the terminal or apply excessive force to the terminal. Use non-corrosive rosin flux. Remove the lens assembly (color lens, marking plate, lens holder, and spring) by holding the color lens recesses with the Lens Removal Tool (MT-101) and pulling it out. Remove the marking plate by disengaging the latches between the color lens and lens holder. The marking plate must be engraved on the front side as shown below. Latches Installing the Socket Install the socket on the control unit with the TOP markings on the control unit and the socket placed in the same direction. Color lens Engraving Area Marking Plate Spring Lens Retaining Holder Groove Spring Note: Make sure that the spring is inserted in the correct direction. The base of spring must fit the groove in the holder. • Installation Place the marking plate on the lens holder in the correct direction, and press the color lens onto the lens holder to engage the latches. Put the spring on the lens holder and insert the lens holder into the housing in the correct direction. • Installing Non-illuminated Button Non-illuminated pushbuttons contain a marking plate like illuminated units. Be sure to install the marking plate when replacing the button. Replacing the LED Lamp • Removal Use the lamp holder tool (OR-66) to remove lamps. Do not use pliers. • Installation Use the lamp holder tool (OR-66) to install lamps. Note the correct side of the tool for removal or installation. Lamp Holder Tool OR-66 (ø8, ø10, ø12 series) For removing lamps Operating Voltage of LED Lamps The operating voltage is measured at complete DC. When using a pulsating voltage such as a full-wave rectification voltage, keep peak currents within the forward current If. Peak currents exceeding the If may shorten the LED lamp life. Other Notes • Close Proximity Mounting When mounting pilot lights or illuminated pushbuttons collectively or lighting them continuously, heat may cause the ambient temperature to rise above the rated operating temperature. When the mounting panel is not made of metal or when the control units are mounted in an enclosed panel, provide for ventilation or lower the operating voltage. • Replacement of Buttons (Illuminated/Non-illuminated) Do not replace buttons of maintained action units while the button is in the locked position. Replacing the button in the locked position may damage the internal mechanism. Be sure to release the button before replacing. • Operating and Storage Environment 1. Make sure that the operating/storage temperature and humidity are within the ratings. 2. Do not use enclosed type units in an environment subject to oil, water or dust accumulation. • Microswitch Contacts Do not connect NO and NC contacts of the microswitch to different voltages or different power sources to prevent a dead short-circuit. For installing lamps Panel Mounting When mounting the control units into a panel, use the optional locking ring wrench (MT-003) to tighten the locking ring. Do not use pliers. Tightening torque must not exceed 0.29 N·m. Excessive tightening will damage the locking ring. 36 (06/11/10) A8 Series Miniature Control Units ø8 Short 22-mm-long body miniature control unit series with LED illumination face and snap-action switching. • • • • Bright and clear LED illumination. 8-mm mounting holes All series have terminals on the same plane.
