Use a model with a mechanical lock. 12 D4BL Safety Precautions ● Be sure to read the precautions for all D4BL models in the website at: http://www.ia.omron.com/. Precautions for Correct Use DANGER Injury may occasionally occur. Always check to make sure that the safety functions operate correctly before using the machine. The safety functions may not operate correctly because of wiring mistakes, setting mistakes, or Switch malfunction, causing some machines to continue operating in situations where they should be stopped. Injury may occasionally occur. If the machine is used with the release key in the UNLOCK position, the electromagnetic lock may not operate, causing some machines to continue operating in situations where they should be stopped. Be sure to put the release key in the LOCK position before using the machine. Also, check the condition of the lock and safety circuits. Injury may occasionally occur. When the electromagnetic lock function or Switch function is damaged, some machines may continue operating in situations where they should be stopped. Do not use the electromagnetic lock function of the Switch in place of a door lock. Always provide a lock separate from the Switch, attach a warning seal to prevent people from using excessive force to open the door when it is locked, or provide an indicator lamp to show the locked/unlocked status of the door. Appropriate Tightening Torque Loose screws may result in malfunction. Tighten the screws to the specified torques. No. 1 Appropriate tightening torque Type 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 * 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 5. Two, M5 Operation Key mounting screw 3. Four, M3.5 head-mounting screw 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 the Switch specifies the amount of water penetration after the Switch is submerged in water for a certain period of time.) • Always attach the cover after completing wiring and before using the Switch. Also, do not turn ON the Switch with the cover open. Doing so may result in electric shock. • Make sure the Switch is mounted securely to prevent it from falling off. Otherwise injury may result. Stopper Installation 2. Four, M4 cover-mounting screw 6. Conduit 7. Conduit cap 4. Four, M5 switch-mounting screw Auxiliary Release Key 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. Do not subject the Switch to a shock that exceeds the Switch's shock resistance of 1,000 m/s2. • 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. Release key is not provided with D4BL-2GRD-AT.) Incorrect Correct LOCK Stopper UNLOCK Auxiliary release key Switch Incorrect Gap Set zone Correct • When a Switch with a solenoid lock is in a locked state (i.e., when the solenoid is ON), do not change the release key from the LOCK to the UNLOCK position. Internal parts may be damaged. • 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. • Make sure that the auxiliary release key is kept with the person in charge. • 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. • Before attaching the cover to the D4BL, make sure that the auxiliary release key position is set to LOCK. 13 D4BL Solenoid Lock Models Head Direction 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 Use four M5 screws and spring washers to mount the Switch and Operation Key, and tighten the screws to a suitable torque. To ensure safety, use screws that cannot be easily removed or another means to prevent the Switch and Operation Key from easily being removed. • The head can be mounted in four directions by loosening the four screws holding the head. To remove the head, turn the head at the surface mating with the Switch body 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 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 misalignment, 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. Incorrect Rotating lever (with protruding part) Built-in switch • 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 enter through the key hole on the head. Greater than ±0.3 Incorrect Greater than ±0.3 • Do not use the D4BS operation key. 14 D4BL Processing and Connecting Cable/ Conduit Cable Connection Example 1. Connect the wires to the terminals in the order shown below for wiring efficiency. • The following procedures are recommended for mounting and wiring the indicator unit securely. • To ensure IP67, use OMRON’s [email protected] and Nippon Flex’s ABS-08Pg13.5 and ABS-12 Pg13.5 Connectors. • Recommended cable: UL2464-type cable that is AWG20 to AWG18 (0.5 to 1.0 mm2) in size and has seven conductors • 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. Terminal no. Lp (mm) Lv (mm) E1 30±2 80±2 E2 35±2 75±2 31 45±2 60±2 12 55±2 50±2 23 (21) 65±2 45±2 24 (22) 70±2 35±2 90±2 50±2 a (mm) Twist the wire two or three times and make sure that no bare wire exists outside the terminal when tightening the terminal. 2. The insulation sheath of the seven-conductor cable must come into contact with the wall of the conduit mouth, side A or side B. 8±1 • Properly attach and securely tighten the provided conduit cap to the unused conduit opening to the suitable tightening torque when wiring the D4BL. Insulation sheath edge Others Do not touch the solenoid because the solenoid radiates heat while power is being supplied. 15 Terms and Conditions Agreement Read and understand this catalog.
