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. 5 D4NL Connections Internal Circuit Diagram Circuit Connection Example Indicator Connection Example for D4NL-@F@@-B • Terminals 12 and 41 are connected internally. When connecting 10 to 115 VAC/VDC R 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 ZD LED terminals 11 and 12 and terminals 41 and 42 below). Connect the R terminals individually when using as auxiliary-circuit inputs (e.g., terminals 21 and 22 for safety-door open/closed monitoring and Constant-current diode terminals 51 and 52 for monitoring the lock status). • In the following connection example, terminals 21 and 22 and Solenoid terminals 51 and 52 are used as auxiliary-circuit inputs. • Direct opening contacts used as safety-circuit inputs are indicated 24 VDC 110 VAC/230 VAC with the mark. Terminals 11 and 42, and terminals 21 and 22 E1 (+) E1 (+) have direct opening contacts. • Connect the indicators in parallel to the auxiliary circuits or E2 (−) terminals E1 and E2 (D4NL-@@@A-B, -@@@G-B, -@@@B-B, and E2 (−) -@@@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 41 42 Safety 11 circuit 52 Auxiliary 21 circuit 22 Auxiliary circuit 34 Auxiliary 33 circuit E2 (−) E1 (+) Indicator (Orange) O1 O2 6 D4NL Operation Method Operation Principles Solenoid Operation Key OFF ON OFF Mechanical lock models When the Operation Key is inserted, it is The solenoid is released only when the Spring locked by the lock spring.
