D4BL

Release Protective Cover Locks Using Controller Signals or Pushbutton 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 mechanism where the lock is only released when voltage is applied to the solenoid.

• Conforms to EN (TÜV) standards corresponding to the CE marking.

• Approved by UL, CSA, BIA, SUVA 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-approved is indicated by on the 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 double door are available.

• The mounting direction of the head can be changed to allow the Operation Key to be inserted from four directions.

Note: Be sure to read the “Safety Precautions” on page A-78 and the

“Precautions for All Safety Door Switches” on page A-2.

■ 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 the solenoid input terminals as shown below.

• The indicators can be used to confirm the open/closed status of the door, the ON/OFF status of the power supply, and the ON/OFF status of the

solenoid.

• 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.

• Be sure to use a special pushbutton switch to stop and start machinery and release locks.
