Question

The key comes out of D4DL/D4BL Safety-door Switches with a mechanical lock if I insert the key and then turn OFF the solenoid. What causes this and how can I correct it?

Answer

Cause: The release key is in the unlock position. The lock will not engage in the unlock position.

Countermeasure: Set the release key to the lock position.
