Safety interlock Switches D4BL D4Bl guard lock Safety-Door Switch Release protective cover locks using controller signals or pushbut- ton switches after the cutting tool stops moving due to inertia A mechanical lock is applied automatically when the Operation Key is inserted. A high level of safety is achieved using a mecha- nism where the lock is only released when voltage is applied to the solenoid. Conforms to EN (TV) standards corresponding to the CE marking Certified by UL, CSA and CCC standards The Switch contact is opened by a direct opening mechanism (NC contacts only) when the protective cover is opened. Direct opening mechanism that is EN-certified is indicated by on the Switch Auxiliary release key ensures easy maintenance and unlocks the door in the case of a power failure.
