Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced. *1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the D4NL in places where foreign material may enter through the key hole on the head, otherwise Switch damage or malfunctioning may occur. *2. The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your OMRON representative. *3. Do not pass the 3 A, 250 VAC load through more than 2 circuits. *4. These figures are minimum requirements for safe operation. *5. This figure is based on the GS-ET-19 evaluation method. *6. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual load beforehand. 6 D4NL Connections Internal Circuit Diagram Circuit Connection Example Indicator Connection Example for D4NL-@F@@-B 10 to 115 VAC/VDC R ZD LED R Constant-current diode Solenoid 24 VDC E1 (+) 110 VAC/230 VAC E1 (+) E2 (−) E2 (−) • Terminals 12 and 41 are connected internally. When connecting inputs to safety circuits, use terminals 11 and 42. (GS-ET-19). • Connect terminals 21 and 22 and terminals 51 and 52 in series when using as safety-circuit inputs (redundancy circuit for terminals 11 and 12 and terminals 41 and 42 below). Connect the terminals individually when using as auxiliary-circuit inputs (e.g., terminals 21 and 22 for safety-door open/closed monitoring and terminals 51 and 52 for monitoring the lock status). • In the following connection example, terminals 21 and 22 and terminals 51 and 52 are used as auxiliary-circuit inputs. • Direct opening contacts used as safety-circuit inputs are indicated with the mark. Terminals 11 and 42, and terminals 21 and 22 have direct opening contacts. • Connect the indicators in parallel to the auxiliary circuits or terminals E1 and E2 (D4NL-@@@A-B, -@@@G-B, -@@@B-B, and -@@@H-B only). Connecting to contacts with direct opening mechanisms may result in short-circuit current flowing if the indicator is destroyed, possibly resulting in incorrect equipment operation. • Do not switch circuits for two or more standard loads at the same time. Doing so may adversely affect insulation performance. • DC solenoids have polarity. Confirm terminal polarity before wiring. 51 12 11 41 42 52 21 22 34 33 Safety circuit Auxiliary circuit Auxiliary circuit Auxiliary circuit E2 (−) E1 (+) Indicator (Orange) O1 O2 7 D4NL Operation Method Operation Principles Solenoid Operation Key ON OFF OFF Mechanical lock models When the Operation Key is inserted, it is locked by the lock spring. The door will stay locked even if there is a power interruption. Spring Lock plate Solenoid Operation Key Plunger The solenoid is released only when the lock is turned ON. ON OFF OFF Solenoid lock models If the solenoid is OFF, the door will not be locked when the Operation Key is inserted. This means that the door can be opened and closed easily when replacing workpieces or parts. Spring Lock plate The door is locked only when the solenoid is turned ON. This means that the door will be unlocked if there is a power interruption and so this model cannot be used in systems that would maintain a hazardous state (e.g., systems requiring toxic gases, high temperatures, or gears that would continue to turn due to inertia).

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. Installation • Make sure the Switch is mounted securely to prevent it from falling off. Otherwise injury may result. • Do not use the Switch as a stopper. Be sure to install a stopper as shown in the following illustration to ensure that the base of the Operation Key does not strike the Head, and adjust the stopper to be within the setting zone (0.5 to 3 mm) of the base of the Operation Key. • Do not subject the Switch to a shock that exceeds the Switch's shock resistance of 1,000 m/s2. Operation Key Injury may occasionally occur. Always ensure that the release key is set to "UNLOCK" or that the Operation Key is inserted before changing the direction of the head. Not doing so may damage the Switch, causing some machines to continue operating in situations where they should be stopped. Refer to “Release Key” on page 16. 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. !CAUTION Electric shock may occasionally occur. Do not use metal connectors or metal conduits. Precautions for Safe Use Installation Environment • 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.) UNLOCK LOCK Precautions for Correct Use The Switch contacts can be used with either standard loads or microloads. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced. Release Key • The release key is used to unlock the Switch in case of emergency or if the power supply to the Switch stops. • If the release key setting is changed from LOCK to UNLOCK, the lock will be released and the safety door can be opened (mechanical lock models only). • The release key is set in the unlock position at the factory for the D4NL-@@@A/B/C and to the lock position for the D4NL-@@@G/H/ J. • Do not use the release key to start or stop machines. • The auxiliary lock must only be released by authorized personnel. • Do not impose a force exceeding 1 N·m on the release key screws. The release key may be damaged and may not operate properly. • To prevent the release key from being used by unauthorized personnel, set it to LOCK and seal it with sealing wax. Figure 1 D4NL-@@@@-@S UNLOCK LOCK Wiring • Do not switch circuits for two or more standard loads (250 VAC, 3 A). Doing so may adversely affect insulation performance. • Always attach the cover after completing wiring and before using the Switch. Do not supply power when the cover is not attached. Electric shock may occur if the Switch is used without the cover attached. Stopper Set zone (0.5 to 3 mm) D4NL-@@@@-@4S UNLOCK LOCK D4NL-@@@@-@ UNLOCK D4NL-@@@@-@4 LOCK UNLOCK LOCK Hinged Door If an attempt is made to open the door beyond the lock position when the Switch is used for a hinged door at a location near to the hinged side, where the Operation Key’s insertion radius is comparatively small, the force imposed will be much larger than for locations far from the hinged side, and the lock may be damaged. Mount the Switch close to the handle. 16 D4NL Solenoid Lock Models Attaching a Cover 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. Mounting Securing the Door Appropriate Tightening Torque • Be sure to tighten each screw of the Switch properly. Loose screws may result in malfunction. Type Appropriate tightening torque Terminal screw 0.59 to 0.78 N·m Cover mounting screw 0.49 to 0.69 N·m Head mounting screw 0.49 to 0.59 N·m Operation Key mounting screw 2.35 to 2.75 N·m Switch mounting screw 0.49 to 0.69 N·m Connector 1.77 to 2.16 N·m Cap screw 1.27 to 1.67 N·m • When loosening a screw with an electrical screwdriver or similar tool while pressing down on the screw head, do not continue turning the screw past the point where the threads disengage. Doing so may strip the end of the threads. Switch and Operation Key Mounting • Use M4 screws and 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. Mounting Holes for Switches Mounting Holes for Operation Keys Horizontal/Vertical Mounting (D4DS-K1/-K2) Two, M4 Three, M4 32±0.1 15 ±0.1 55±0.1 • When attaching a cover, be sure that the seal rubber is in place and that there is no foreign material present. If the cover is attached with the seal rubber out of place or if foreign material is stuck to the rubber, a proper seal will not be obtained. • Do not use any screws to connect the cover other than the specified ones. The seal characteristics may be reduced. Adjustable Mounting: Horizontal (D4DS-K3) Two, M4 40 ±0.1 79±0.1 Adjustable Mounting: Horizontal/Vertical (D4DS-K5) Two, M4 41±0.1 or, 43±0.1 • If the Switch is back-mounted, the release key can be operated only from the bottom and the indicator cannot be used. • Ensure that the alignment offset between the Operation Key and the key hole does not exceed ±1 mm. If the Operation Key is offset or at an angle, accelerated wear or damage to the Switch may result. • Observe the specified insertion radius for the Operation Key and insert it in a direction perpendicular to the key hole. • Do not impose excessive force on the Operation Key while the Key is inserted into the Switch or drop the Switch with the Operation Key inserted. Doing either of these may deform the Key or break the Switch. When the door is closed (with the Operation Key inserted), the Operation Key may exceed the set zone because of, for example, the door's own weight, machine vibration, or the door cushion rubber. Then, when an attempt is made to open the door, it may result in damage or malfunction. Also, it may not be possible to unlock the Switch if there is weight placed on the Operation Key. Do not rely on the Switch to substitute for a door locking device. Secure the door with a stopper so that the Operation Key remains within the set zone. Set zone (0.5 to 3 mm) Operation key Solenoid • The solenoid will heat when it carries current. Do not touch it. • A DC solenoid has polarity. Confirm terminal polarity before wiring it. Wiring Circuit Connection Example for the D4NL-@F@@-B • Direct opening contacts used as safety-circuit inputs are indicated with the mark. Terminals 11 and 42, and terminals 21 and 22 have direct opening contacts. • Connect terminals 21 and 22 and terminals 51 and 52 in series when using as safety-circuit inputs (redundancy circuit for terminals 11 and 12 and terminals 41 and 42 below). Connect the terminals individually when using as auxiliary-circuit inputs (e.g., terminals 21 and 22 for safety-door open/closed monitoring and terminals 51 and 52 for monitoring the lock status). • In the following connection example, terminals 21 and 22 and terminals 51 and 52 are used as auxiliary-circuit inputs. • Connect the indicators in parallel to the auxiliary circuits or terminals E1 and E2 (D4NL-@@@A-B, -@@@G-B, -@@@B-B, and -@@@H-B only). Connecting to contacts with direct opening mechanisms may result in short-circuit current flowing if the indicator is destroyed, possibly resulting in incorrect equipment operation. 51 12 11 41 42 52 21 22 34 33 Safety circuit Auxiliary circuit Auxiliary circuit Auxiliary circuit E2 (−) E1 (+) Indicator (Orange) Head Direction • Remove the four screws of the head to enable changing the mounting direction of the head. The head can be mounted in four directions. Ensure that no foreign material enters the interior of the Switch. • Do not change the head direction with the cover removed. • Do not insert or remove the Operation Key with the Switch head removed. Doing so may make it impossible to insert the Operation Key. O1 O2 17 D4NL Recommended Connectors Wiring Precautions • Do not wire the Switch while power is being supplied. Doing so may result in electric shock. • Do not let particles, such as small pieces of lead wire, enter the switch body when wiring. • When connecting to the terminals via insulating tube and M3.5 crimp terminals, cross the crimp terminals as shown above so that they do not rise up onto the case or the cover. • Applicable lead wire size: AWG20 to AWG18 (0.5 to 0.75 mm2). Use lead wires of an appropriate length. Not doing so may result in excess length causing the cover to rise and not fit properly. • Do not push crimp terminals into gaps in the case interior. Doing so may cause damage or deformation of the case. • Use terminals having the thickness of 0.5 mm or less to avoid the contact between the terminal and the interior of the Switch case. [Reference] The terminals listed below have thickness of 0.5 mm or less. Manufacturer J.S.T. Mfg Co. Model FN0.5-3.7 (F Type) No. 5-3.7 (Straight Type) • Use a connector with a screw section not exceeding 11 mm. Otherwise the screws will protrude into the case interior. The connectors given in the following table have connectors with screw sections not exceeding 11 mm. Use the following connectors to ensure conformance to IP67.
