11 / 16 page D4DL D4DL 11 Precautions ! WARNING Do not dismount the operation key from the door intentionally and insert it to the switch with the door open. Machine may start operating and injury or death may be caused. ! CAUTION Do not disassemble or touch inside under power-on. Electric shock hazard may be caused. Do not use metal connectors or conduits with this switch. Rigid connectors and conduits may damage the switch. The broken conduit hole may cause an electrical shock hazard. Install the operation key so that it will not hit the operator when the door is open. After-changing the release key to the UNLOCK position or inserting the operation key, change the head direction. Otherwise, the switch may malfunction and injuries may occur due to mis-operation of the device. NOTICE If the D4DL is applied to an emergency stop circuit or safety circuit for prevention of injury, use the NC contact, which incorporates a positive opening mechanism, and make sure that the D4DL oper- ates in positive mode. Furthermore, secure the D4DL with screws or equivalent parts that are tightened in a single direction so that the D4DL or operation key cannot be easily removed or provide a protection cover to the D4DL and post a warning label near the D4DL. To protect the D4DL from damage due to short-circuits, connect the D4DL in parallel to a fuse that has a breaking current 1.5 to 2 times the rated current of the D4DL. If the D4DL is used under EN-ap- proved rating conditions, use a 10 A fuse, type gI or gG conforming to IEC 269. Do not supply power to the D4DL while wiring the D4DL. In order to prevent the D4DL from burning due to overvoltage, inser- tion of a protection fuse into the solenoid circuits is recommended. Do not use the D4DL in locations subject to explosive or flammable gases. Make sure that the load current does not exceed the rated current and that the load terminals are wired correctly. Pay utmost attention to correctly wire each terminal. After mounting and adjusting the D4DL, make sure that the D4DL operates properly. If the D4DL is imposed with force exceeding the lock strength, the D4DL may break and the equipment may continue operating. Do not drop or disassemble the D4DL. Release Key The release key is used to unlock the D4DL in case of emergency or if the power supply to the D4DL fails. Use an appropriate tool to set the release key to UNLOCK so that the lock will be released and the door can be opened. The release key is set at the UNLOCK position. Set the release key to the LOCK position before use. Mechanical Lock Type Release key The release key applied to the door of a machine room ensures the safety of people adjusting the equipment in the machine room. If the release key is set to UNLOCK, the door will not be locked when the door is closed and no power will be supplied to the equipment. Do not use the release key to start or stop machines. To prevent the release key from being used carelessly by unautho- rized people, set the release key of the D4DL in normal operation to UNLOCK and seal the release key with seal wax. Mounting Be sure to mount the D4DL with a stopper as shown in the following illustration. Do not use the D4DL Switch as a stopper. Door Stopper Operation key Switch Set zone (0.5 to 3 mm) Solenoid Lock Type The solenoid lock locks the door only when power is supplied to the solenoid. Therefore, the door will be unlocked if the power supply to the solenoid fails. Therefore, do not use the solenoid lock type for machines that may be operating and dangerous even after the ma- chine stops operating because of inertia. Life Expectancy The life of the D4DL will vary with the switching conditions. Before applying the D4DL, test the D4DL under actual operating conditions and be sure to use the D4DL in actual operation within switching times that will not lower the performance of the D4DL. Operating Environment The D4DL is for indoor use only. Do not use the D4DL outdoors. Otherwise, the D4DL may malfunction. Do not use the D4DL in the following locations: Locations with severe changes in temperature Locations with excessive humidity that may cause condensation Locations with excessive vibration Locations where metal dust, oil, or chemical may be sprayed onto the D4DL Operation Key Be sure to use the dedicated Operation Key only. Do not operate the D4DL with anything other than the dedicated Operation Key. Otherwise, the safety of the system may not be maintained. Do not impose excessive force on the Operation Key inserted into the D4DL or drop the D4DL with the Operation Key inserted. Other- wise, the Operation Key may be deformed or broken. Force imposed Drop Secure the Operation Key with a one-way screw, or an equivalent, so that the Operation Key cannot be easily removed. |
