Release Protective Cover Locks Using Controller Signals or Pushbutton Switches after the Cutting Tool Stops Moving Due to Inertia Note: Contact your sales representative for details on models with safety standard certification. -A mechanical lock is applied automatically when the Operation Key is inserted. A high level of safety is achieved using a mechanism where the lock is only released when voltage is applied to the solenoid. > Conforms to EN (TUV) 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 theQ Switch. > Auxiliary release key ensures easy maintenance and unlocks the door in the case of a power failure. -Tough aluminum die-cast body incorporating a switch box with degree of protection satisfying IP67, UL, and CSA TYPE6P, 13. - Equipped with a horizontal and vertical conduit opening. - Models incorporating easy-to-see indicators for monitoring and those using an adjustable Operation Key for a swinging door are available. -The mounting direction of the head can be changed to allow the Operation Key to be inserted from four directions. - Conforms to ISO 14119.

Specifications Standards and EC Directives Conforms to the following EC Directives: • Machinery Directive • Low Voltage Directive • EN ISO 14119 Certified Standards Note: The UL/CSA certified rating for products with indicators (-A) is 6 A/115 VAC.

Characteristics Degree of protection *1 Note: The above values are initial values. *1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for the operating conditions and environment beforehand. Although the switch box is protected from dust, oil or water penetration, do not use the D4BL in places where dust, oil, water, or chemicals may enter through the key hole on the head, otherwise Switch damage or malfunctioning may occur. *2. The durability is for an ambient temperature of 5 to 35°C and an...

D4BL Circuit Connection Example • Terminals 11 and 32 are connected internally and so connect terminals 12 and 31 for safety-circuit input. (GS-ET-19). • When using indicators, connect them to the auxiliary circuit side (monitor circuit) or in parallel between E1 and E2 as shown below. • Do not connect the indicators in parallel with the direct opening contact. If the indicators are broken, a short-circuit current may flow, causing equipment to malfunction. • The 24 VDC solenoid terminals have polarity. Confirm the polarity before wiring. 1.
