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 on the Switch.

• 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.

Note: Be sure to read the “Safety Precautions” on page A-78 and the

■ 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

Refer to the “Precautions for All Switches” on page I-2 and “Precautions for All Safety Door Switches” on page A-2.

!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-

Switches

absorbing damper, which is provided before shipping.

■ Precautions for Safe Use

•

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

D4BL

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. Otherwise, accelerated wear or breaking may result.

• 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.

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%.

To prevent the D4BL from burning due to overvoltage, insert a protection fuse into the solenoid circuit.

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.

■ Precautions for Correct Use

Tightening Torque

Loose screws may result in malfunction. Tighten the screws to the specified torques.

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 (See note.) 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

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

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 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.

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

A-78 Guard Lock Safety-door Switch D4BL

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.

Mounting Dimensions

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 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.

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 rotating lever. The head, plunger, or the built-in switch may be damaged as a result.

■ Processing and Connecting Cable/Conduit

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 material 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.

To ensure IP67, use OMRON’s SC-@M and Nippon Flex’s ABS08Pg13.5 and ABS-12 Pg13.5 Connectors.

Recommended cable: UL2464-type cable that is AWG20 to AWG18 (0.5 to 1.0 mm

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.
