Circuit Connection Example
• Do not connect the indicators to the safety contact terminals (1112-31-32) or the safety circuit side.
• 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.

Precautions
Stopper
Caution
Do not insert the Operation Key to the Switch with the door open.
Before using the machine, be sure to remove the shock-absorbing
damper, which is provided before shipping. Otherwise the machine may start operating and injury may be caused.
Stopper
Mount the Operation Key at a location where it will not come in contact with users when the door is opened or closed.
When operating the D4BL as a part of a safety circuit or an emergency stop circuit to prevent injury, operate the NC contacts that
have a direct opening mechanism in direct opening mode. For safety
purposes, tighten the switch body and Operation Key with one-way
screws or equivalents or install a switch protection cover and warning label for safety purposes to prevent easy removal of the D4BL.
Switch
Do not use the Switch as
a stopper. When mounting
the Switch, be sure to locate a stopper as shown
in the following illustration
to prevent the top of the
Operation Key from hitting
the switch head.
Connect the fuse to the D4BL in series to prevent it from short-circuit
damage. The value of the breaking current of the fuse must be calculated by multiplying rated current by 150% to 200%.
When using the D4BL with EN ratings, use 10-A fuse Type gI or gG
that complies with IEC60269.
In order to prevent the D4BL from burning due to overvoltage, insert
a protection fuse into the solenoid circuit.
If the D4BL is imposed with force exceeding the lock strength, the
D4BL may break and the equipment may continue to operate.
Correct Use
Auxiliary Release Key
Due to the wear and tear of the sealing of the D4BL, water and some
types of oil and chemical sprayed onto the D4BL may cause contact
or insulation failures, current leakages, or fires.
The auxiliary release key is used to unlock the D4BL in case of
emergency or in case the power supply to the D4BL fails.
Use an appropriate tool to set the auxiliary release key to UNLOCK
so that the lock will be released and the door can be opened.
LOCK
Operating Environment
Do not use the D4BL in the following locations.
•
•
•
•
Locations subject to severe temperature changes
Locations subject to high temperatures or condensation
Locations subject to severe vibration
Locations where the product may come in contact with metal dust,
oil, or chemicals
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.
To lock the door, set the auxiliary release key to LOCK.
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.
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.
±0.3 min.
Make sure that the auxiliary release key is kept with the person in
charge.
Before attaching the cover to the D4BL, make sure that the auxiliary
release key position is set to LOCK.
±0.3 min.
Do not drop the D4BL with the Operation Key inserted, otherwise the
Operation Key may deform or break.

Head Directions
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.

Be sure to check the mechanical lock and solenoid release functions
when mounting the D4BL.
If the head direction is changed, recheck the tightening torque of
each of screw. Make sure that no foreign materials will penetrate
through the key hole on the head.
Mounting the Cover
When tightening the cover, first check the specified torque, and then
tighten each screw to the that torque. Also, make sure that no foreign
matter has entered the switch.
When mounting the cover, make sure that the cover and switch box
are properly aligned.

Safety Sensors / Components
Processing and Connecting Cable/Conduit
The following procedures are recommended for mounting and wiring
the indicator unit securely.
In order to ensure IP67, use OMRON’s SC-#M and Nippon Flex’s
ABS-08Pg13.5 and ABS-12 Pg13.5 Connectors.
Cable Connection Example
1. Connect the wires to the terminals in the order shown below for
wiring efficiency.
Recommended cable: UL2464-type cable that is 20 to 18 AWG (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 in order 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.

Maintenance and Repairs
Contact your OMRON representative for any repair or maintenance
work on the D4BL. The D4BL must not be maintained or repaired by
any unauthorized party.
Others
Do not touch the solenoid because the solenoid radiates heat while
power is being supplied.
