Solenoid Lock Models
The solenoid lock locks the door only when power is supplied to the
solenoid. Therefore, the door will be unlocked if the power supply to
the solenoid stops. Therefore, do not use solenoid lock models for
machines that may be operating and dangerous even after the
machine stops operating.

Securing the Door
When the door is closed (with the Operation Key inserted), the
Operation Key may exceed the set zone because of, for example, the
door's own weight, machine vibration, or the door cushion rubber.
Then, when an attempt is made to open the door, it may result in
damage or malfunction. Also, it may not be possible to unlock the
Switch if there is weight placed on the Operation Key. Do not rely on
the Switch to substitute for a door locking device. Secure the door with
a stopper so that the Operation Key remains within the set zone.
