Circuit Connection Example

• Do not connect the indicators to the safety contact terminals (11-12-31-32) 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.

1. Orange: Lights when the solenoid turns ON. Green: Lights when the door opens.

3. Orange: Lights when the solenoid turns ON. Green: Lights when door closes.

Internal Circuit

• 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.

2. Orange: Lights when the solenoid turns ON. Green: Lights when power turns ON.

4. Orange: Lights when the solenoid turns ON. Green: Lights when power turns ON.

2. In the above diagrams, the Operation Key is inserted from the front.

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.

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.

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 gl 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.

Auxiliary Release Key

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.

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.

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.

Before attaching the cover to the D4BL, make sure that the auxiliary release key position is set to LOCK.

Stopper

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.

Correct Use

Operating Environment

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.

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

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 ± 0.3mm vertically or horizontally. Be sure to mount the D4BL correctly without leaning, otherwise the D4BL may soon break or wear out.

Do not drop the D4BL with the Operation Key inserted, otherwise the Operation Key may deform or break.

The head is constructed so that it cannot be operated with tools such as screwdrivers. Always use OMRON's Operation Key to operate the head in order to ensure the safety of the machine and protect the D4BL from damage.

The Operation Key provided for the D4BL is not compatible with that of the D4BS.

Mount the Operation Key and secure it with one-way screws or equivalents to prevent easy removal of the D4BL.

Securing the Door

If the Operation Key on the closed door is pulled outside the set zone by a force caused by vibration, the door's weight, or the door cushion rubber, the D4BL may be damaged. Secure the door with hooks so that it will remain within the set zone.

Tightening Torque

Be sure to tighten each screw of the D4BL properly, otherwise the D4BL may malfunction.

	Type	Torque
1	M3.5 terminal screw (including terminal screw)	0.59 to 0.78 N·m
2	Cover mounting screw	1.18 to 1.37 N·m
3	Head mounting screw	0.78 to 0.98 N·m
4	M5 body mounting screw	4.90 to 5.88 N·m
5	Operation Key mounting screw	2.35 to 2.75 N·m
6	Connector	1.77 to 2.16 N·m
7	Cap screw	1.27 to 1.67 N·m

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.

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.

Recommended cable: UL2464-type cable that is 20 to 18 AWG (0.5 to 1.0 mm^2 ) 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 2.16N· m .

Connect the indicator unit after connecting the seven-conductor cable.

Properly attach and securely tighten the provided conduit cap to the unused conduit opening when wiring the D4BL.

Cable Connection Example

1. Connect the wires to the terminals in the order shown below for wiring efficiency.

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.

1. The insulation sheath of the seven-conductor cable must come into contact with the wall of the conduit mouth, side A or side B.

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.
