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.
Switch and Operation Key Mounting
Mount the D4BL and Operation Key with four M5 screws with
washers and tighten each screw to the specified torque.

Operation Key
The D4BL is provided with a shock-absorbing damper to protect the
D4BL from damage that may result from dropping the D4BL during
transportation. Be sure to remove the damper after mounting the
D4BL.
The mounting tolerance of the Operation Key is
±0.3 mm vertically or
horizontally. Be sure to mount the D4BL correctly without leaning,
otherwise the D4BL may soon break or wear out.
Observe the specified insertion radius for the Operation Key and
insert it in a direction perpendicular to the key hole.
The Operation Key for the D4BL is different from the one for the
D4BS.
Head Direction
The head can be mounted in four directions. To remove the head,
turn the head by 45
° as shown in figures (A) and (B) below.
To change the direction of the head, make sure that the protruding
part of the rotating lever engages with the groove of the plunger.
Then turn the head clockwise or counterclockwise to the desired
direction. At that time, make sure that the groove of the plunger is
located under the rotating lever. If the direction of the head is not set
when the plunger is rotated by 45
°, the groove of the plunger presses
the rotating lever. The head, plunger, or the built-in switch may be
damaged as a result.
