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.

Safety Door Switches 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 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 p
