Turn over the head to set the desired operation (CW, CCW, or both). The desired operation can be selected by setting the mode selector knob shown in the figure. This knob is factory set to the "CW + CCW" (two-way operation) position. 3. Set the CW hole on the head at the operation position mark (arrow) for clockwise operation or set the CCW hole right at the arrow for counterclockwise operation. In either case, be sure to set the hole position exactly at the arrow point. Head cover (Push and rotate) Precautions Tightening Torque If the D4B-jN is applied to an emergency stop circuit or safety circuit for prevention of injury, use the D4B-jN model that has an NC contact equipped with a force-separation mechanism, and make sure that the D4B-jN operates in the positive mode. In addition, secure the D4B-jN with screws that are tightened in a single direction so that the D4B-jN cannot be easily removed. Then provide a protection cover for the D4B-jN and post a warning label near the D4B-jN. (3) Since loose screws may cause a malfunction, (4) tighten each screw to the appropriate torque. In order to protect the D4B-jN from damage due to short-circuiting, connect a fuse breaking a current 1.5 to 2 times higher than the rated current in parallel with the D4B-jN. (1) If an application satisfying EN standards is to employ the D4BL, apply the 10-A gI or gG fuse approved by IEC269. Do not apply the D4B-jN to the door without applying a stopper to the door. (5) If the D4B-jN is used with the actuator normally pressed, the D4B-jN may malfunction or may soon have reset failures. Be sure to check and replace the D4B-jN regularly.

The D4B-jN may malfunction if the D4B-jN is used outdoors. Be sure to use a model with a lever-type actuator for outdoor use instead. Do not connect the bare lead wires directly to the terminals but be sure to connect each of them by using an insulation tube and M3.5 round solderless terminals and tighten each terminal screw within the specified torque range. The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size. Do not use the D4B-jN in the following places: * * * * Places with radical temperature changes. Places with excessive humidity that may cause condensation. Places with excessive vibration. Places where metal dust, oil, or chemical may be sprayed to the D4B-jN. Mounting Use four M5 screws with washers to mount the standard model. Be sure to apply the proper torque to tighten each screw. The D4B-jN can be mounted more securely by using the four screws plus two 5 --0.05/--0.15-mm protruding parts, each of which has a maximum height of 4.8 mm as shown below. dz dia.: D dia.: B: L: F: I: 3.7 4.5 7.0 20.2 7.7 9.0 (mm) D dia. dz dia. Make sure that all solderless terminals come into contact with the casing or cover as shown below, or the cover may not be mounted properly or the D4B-jN may malfunction.

The operating position indicator plate has protruding parts which engage with the lever, thus allowing changes to the lever position by 90. The back of the operating position indicator plate has no protruding parts. The lever can be set at any angle by attaching the operating position indicator plate to the Switch so that this side will face the lever. In this case, however, the D4B-jN will not be approved by SUVA or BIA. Make sure that the lever engages with the operating position indicator plate securely so that the lever will not slip. Incorrect Crimp-style terminal Changes in Head Mounting Position By removing the screws on the four corners of the head, the head can be reset in any of four directions. Make sure that no foreign materials will penetrate through the head. 16 Crimp-style terminal D4B-N Connector Actuator Load Make sure that each connector is tightened within the specified torque range. The casing may be damaged if the connector is tightened excessively. The load for the actuator (roller) of the Switch must be imposed on the actuator in the horizontal direction, or the actuator or the rotating axis may be deformed or damaged. If the 1/2-14NPT is used, cover the cable and conduit end with sealing tape in order to ensure IP67. Correct The Pg13.5 connector must be Nippon Flex's ABS-08Pg13.5 or ABS-12 Pg13.5. Top View Incorrect Dog Dog Use OMRON's SC-series connector which is suited to the cable in diameter. When using a long lever model like the D4B-jj16N or D4B-jj17N, the Switch may telegraph. To avoid telegraphing, take the following precautions. Properly attach the provided conduit cap to the unused conduit opening and securely tighten the cap screw within the specified torque when wiring the D4B-jN. 1. Set the lever to operate in one direction. (For details, see the data sheet section: CW, CCW or Two-way Operation.) 2. Modify the rear end of the dog to an angle of 15 to 30 as shown below or to a secondary-degree curve. 15 30 30 3. Modify the circuit so as not to detect the wrong operating signals.
