Additionally there may be significant property damage. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, or undesirable effect on product performance. !WARNING When the single beam safety sensor model E3ZS is used as a safety device or a part of safety systems for ensuring safety of personnel, be sure to use it with an appropriate safety controller. !WARNING If the mode selection input (the pink wire) of the receiver is connected to 0V, the output turns ON when light is interrupted (Dark ON), which no longer configures the safety system. Be sure to connect the mode selection input (the pink wire) to 24V DC to make the sensor output ON when light is incident (Light ON). Always maintain a safe distance between the E3ZS and a hazardous part of a machine. Be sure to refer to the related standards (ISO 13855) for the calculation of safety distance. Use an opaque test rod with 18mm in diameter and 200mm or greater in effective length to check the detection capability. The E3ZS cannot detect transparent materials. Do not use the E3ZS in a reflective configuration, otherwise detection may fail. Emitter Reflective Panel Receiver Do not install the E3ZS in a location where it can be affected by wall reflections to avoid detection failure, which may result in serious injury. Wiring must be done while the power is turned OFF. Doing it with the power ON may cause an electric shock. Do not connect the E3ZS to an AC or DC power supply with higher voltage than nominal DC24V. Otherwise the sensor may explode, burn, or cause electric shock. The power supply must conform to regulatory requirements and standards, regarding EMC and electrical equipment safety, of the country where the E3ZS is installed. For example, the power supply must fulfill EN60742 requirements for double insulation and must conform to EMC Directive and Low Voltage Directive in EU. To meet the Category 2, at least 100 diagnostic-tests must be undertaken between two requests for a safetyrelated reaction from the E3ZS. For diagnostic-test intervals, refer to user's manuals of safety controllers to be connected. Precautions for Safe Use 1. When used in combination with a safety controller, also refer to the user's manual of the safety controller for proper connection. 2. A load must not be shorted. A load must not be used with current higher than the rating. Do not apply the reversed supplied voltage. Be sure to route the E3ZS cable separated from high-potential power line or through an exclusive conduit. 3. Do not remove the label (yellow) from the sensor. Doing so may violate the specifications. 4. Wire the cable so that it has some slack and does not prevent personnel or object passage. Allow some leeway for the wires and do not tight the wires when connection cable to G9SP, and confirm that any cable may not block the movements of workers or objects. 5. Do not disassemble, repair or modify the E3ZS. 6. Be sure to dispose of the E3ZS as industrial waste. Precautions for Correct Use 1. Do not install the E3ZS in the following environments: * Areas exposed to intense interference light, such as direct sunlight; * Areas with high-humidity where condensation is likely to occur; * Areas exposed to corrosive, flammable or explosive gases; * Areas in the presence of substances, such as heavy smoke or particulate matter, that may deteriorate product quality; * Areas exposed to vibration or shock levels higher than specification provisions; * Areas where the product may come in direct contact with water, oil, and chemicals; 2. Do not install the E3ZS in water. 3. To extend the cable, use a wire of cross-sectional area 0.3mm2 or more. However do not extend it more than 100m. 4. Be careful not to exceed a tightening torque of 0.5 Nm. Also, if it is not tight enough, vibration may cause it to come loose. 5. When cleaning, avoid using thinner, benzene or acetone. When using multiple sets of E3ZS, arrange them to prevent mutual interference. Failure to do so may cause the sensor not to detect, resulting in serious injury. The E3ZS does not offer protection to the operator's body from projectiles existing the hazardous area. Proper means of mechanical guarding must be provided to ensure protection from these potentially hazardous projectiles. 10 E3ZS 6. Power supply specifications Do not connect to DC distribution network. For combined DC power supply, use the following UL certified products: (1) Limited voltage current circuit that conforms to UL508 Circuit with a power supply that consists of a secondary coil of an insulated transformer that satisfies the following conditions: - Maximum voltage (with no load) : 30Vrms (42.4V peak) or less, and - Maximum current : 8A or less (including short-circuit), or When limited by a circuit protector (fuse, etc.) with the ratings shown in the table below No-load voltage (V peak) Maximum current rating (A) 0 to 20 5.0 More than 20, up to 30 100 Peak voltage value (2) Class 2 power supply unit that conforms to UL1310 (3) Circuit (class 2 circuit) with 30Vrms (42.4V peak) or less of maximum voltage, and which uses a class 2 transformer that conforms to UL1585 as its power supply 7.
