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  
the Switch.  
on  
• 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.

sufficient for the operating conditions and environment beforehand. Although the switch box is protected from dust, oil or water  
penetration, do not use the D4BL in places where dust, oil, water, or chemicals may enter through the key hole on the head, otherwise  
Switch damage or malfunctioning may occur.  
3. The durability is for an ambient temperature of 5°C to 35°C and an ambient humidity of 40% to 70%.  
4. These figures are minimum requirements for safe operation.

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.

Safety Precautions  
Precautions for Correct Use  
!CAUTION  
Do not insert the Operation Key when the door is open.  
The machine may operate, possibly resulting in injury.  
Before using the machine, be sure to remove the shock-  
absorbing damper, which is provided before shipping.  
Tightening Torque  
Loose screws may result in malfunction. Tighten the screws to the  
specified torques.

Do not use the Switch submersed in oil or water or in locations  
continuously subject to splashes of oil or water. Doing so may result  
in oil or water entering the Switch. (The IP67 degree of protection of  
the Switch specifies the amount of water penetration after the  
Switch is submerged in water for a certain period of time.)

Although the Switch body is protected from the ingress of dust or  
water, avoid the ingress of foreign substance through the key hole  
on the head.  
Cap screw  
Otherwise, accelerated wear or breaking may result.  
Note: Use M5 screws. Apply a torque of 4.90 to 5.88 N·m for an Allen-  
head bolt. For a pan head screw, apply a torque of 2.35 to  
2.75 N·m  
Always attach the cover after completing wiring and before using  
the Switch. Electric shock may occur if the Switch is used without  
the cover attached.  
Two, M5 Operation Key mounting screw  
Connect a fuse in series with the D4BL in series to protect it from  
short-circuit damage. The value of the breaking current of the fuse  
must be calculated by multiplying the rated current by 150% to 200%.  
Four, M3.5 head-mounting screw  
To prevent the D4BL from burning due to overvoltage, insert a

Stopper Installation  
Do not use a Switch as a stopper. Be sure to install a stopper as  
shown in the following illustration when mounting the Switch so that  
the Operation Key is within 0.5 to 5 mm of the set zone.

Use the enclosed Release Key to change the lock from LOCK to  
UNLOCK so that the lock will be released and the door can be  
opened. (Applies only to mechanical locks.)  
LOCK  
UNLOCK  
Auxiliary  
release key  
The auxiliary release key applied to the door of a machine room  
ensures the safety of people adjusting the equipment in the machine  
room. If the auxiliary release key is set to UNLOCK, the door will not  
be locked when the door is closed and no power will be supplied to  
the equipment.  
Whenever the lock has been changed to UNLOCK, always return it  
to LOCK before using the Switch.  
Do not use the auxiliary release key to start or stop machines.  
To prevent the auxiliary release key from being handled carelessly by  
unauthorized people, seal the auxiliary release key with sealing wax  
and the provided seal cap to ensure IP67.  
Make sure that the auxiliary release key is kept with the person in  
charge.

Solenoid Lock Models  
Operation Key  
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.  
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.  
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.  
Observe the specified insertion radius for the Operation Key and  
insert it in a direction perpendicular to the key hole.

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.

When tightening the cover, first check the specified torque, and then  
tighten each screw to the that torque. Also, make sure that no foreign

Processing and Connecting Cable/Conduit  
The following procedures are recommended for mounting and wiring  
the indicator unit securely.  
Cable Connection Example  
1. Connect the wires to the terminals in the order shown below for  
To ensure IP67, use OMRON’s SC-@M and Nippon Flex’s ABS-

wiring efficiency.  
Recommended cable: UL2464-type cable that is AWG20 to AWG18  
(0.5 to 1.0 mm2) in size and has seven conductors  
If the 1/2-14NPT is used, cover the cable and conduit end with  
sealing tape to ensure IP67. Tighten the connector to a torque of  
1.77 to 2.16 N·m.  
Connect the indicator unit after connecting the seven-conductor  
cable.  
Tighten each wired terminal clockwise to a torque of 0.59 to  
0.78 N·m.  
Twist the wire two or three times and make sure that no bare wire  
exists outside the terminal when tightening the terminal.
