7 / 9 page D-110 Safety Sensors / Components Precautions Caution Do not dismount the Operation Key from the door intentionally and insert it to the Switch with the door open. Machine may start oper- ating and injury or death may be caused. Mount the Operation Key at a location where it will not come in con- tact with users when the door is opened or closed. When operating the D4BS as a part of a safety category circuit to prevent injury, operate the NC contacts that have a direct opening mechanism in direct opening mode. For safety purposes, tighten the switch body and Operation Key with one-way screws or equivalents or install a switch protection cover and warning label for safety pur- poses to prevent easy removal of the D4BS. Connect the fuse to the D4BS in series to prevent it from short-circuit damage. The value of the breaking current of the fuse must be calcu- lated by multiplying rated current by 150% to 200%. When using the D4BS with EN ratings, use 10-A fuse Type gI or gG that complies with IEC60269. Correct Use Operating Environment Make sure in advance that the environment is suitable, with no oil, water, or chemicals, as these may cause the seal to deteriorate, resulting in faulty contact, faulty isolation, current leakage, or burn- ing. Do not use the D4BS in the following locations: • Locations subject to severe temperature changes • Locations subject to high temperatures or condensation • Locations subject to severe vibration • Locations where the product may come into direct contact with pro- cessing waste or dust Operation Key Be sure to use a special Operation Key only. Do not operate the D4BS with anything other than the special Operation Key, otherwise the D4BS may break or the safety of the system may not be main- tained. Do not impose excessive force on the Operation Key inserted into the D4BS or drop the D4BS with the Operation Key inserted, other- wise the Operation Key may deform or break. Secure the Operation Key with a one-way screw, or an equivalent, so that the Operation Key cannot be easily removed. Securing the Door If the Operation Key on the closed door is pulled outside the set zone by a force caused by vibration, the door’s weight, or the door cushion rubber, the switch contact may be opened (causing the machinery to stop) or the D4BS may be damaged. Secure the door with hooks so that it will remain within the set zone. Mounting Do not use the Switch as a stopper. Be sure to install a stopper as shown in the following illustration when mounting the Switch. The range of space “a” must be determined according to the available set zone of the Operation Key. Refer to Dimensions for the mounting dimension of the Operation Key and mount the Operation Key correctly. The Operation Key will soon become damaged or worn out if it is not mounted correctly. Make sure that the Operation Key can be inserted properly with a tol- erance of ±0.5 mm in the upward, downward, left, or right direction, otherwise the D4BS may soon become damaged.
