Power Supply and Wiring. Take care when using a power supply with an overcurrent detector, because this sensor uses DC-DC converter for its power supply circuit and inrush current may activate the protective circuit for a power supply with an overcurrent detector. Recommended power supply: S8VS-06024 (Omron, DC24 V 2.5 A 60 W) • The supply voltage must be within the rated range (DC24 V ± 10 %). • Reverse connection of the power supply is not allowed. • Unstable voltage may cause unexpected operation of the sensor controller. If such condition is anticipated, use an UPS (Uninterruptible Power Supply). Recommended UPS: S8BA Series (OMRON) • Open-collector outputs should not be short-circuited. • Use the power supply within the rated load. • High-voltage lines and power lines must be wired separately from this product. Wiring them together or placing them in the same duct may cause induction, resulting in malfunction or damage. • Use adequate safety measures, for example fail-safe circuits. • Use a specified-sized wire when wiring. Do not connect wires other than those of the specification to the terminal block. • Do not connect a wire with an only twisted end directly to a terminal block. • For a power supply, use a DC power supply unit provided with a remedy, for example, safety ultralow voltage circuit, to prevent a high voltage from being generated. • Route so that power supply wires are as short as possible. • Use a power supply dedicated for this product, without sharing it with other products. • Before performing any of the following activities, be sure to turn off the product, or breakdown may result. - Connecting or wiring cables - Connecting or disconnecting connectors - Installing or removing Calibration ROM • Do not apply any loads to cables and connectors when wiring. • When inserting or removing an EtherCAT cable, do not put any stress on the calibration ROM. • Before turning ON the power after the product is connected, make sure that the power supply voltage is correct, there are no incorrect connections (e.g. load short-circuit) and the load current is appropriate. Incorrect wiring may result in breakdown of the product. • Handling fiber cables Use them in compliance with the following. This may result in damage to the fiber cable. - Fiber cable bend radiuses must be at least 20 mm. - Do not yank hard on a fiber cable. - Do not step on a fiber cable or place anything heavy on it. - Do not apply any twisting stress to the fiber cable. - Do not forcefully insert, or ben...
Power Supply and Wiring. When using a commercially available switching regulator, make sure that the FG terminal is grounded. • If surge currents are present in the power lines, connect surge absorbers that suit the operating environment. • Use the specified voltage. If voltage exceeding the rating or AC voltage is applied, circuit parts may be burnt or rupture. • Cannot remove the Fiber interface of Sensor Head. If you accidentally remove it, need to repair. Use the optional extension fiber cable ZW-XF70□□R is suitable for the ZW-7000 series, and ZW-XF50□□R for the ZW-5000 series. Only one cable can be extended. • Be sure to use a Sensor Head and Calibration ROM with the same serial number. A pair with different serial numbers cannot operate normally. • Use the configuration software with the combination specified in this manual, or the system may operate faultily. • Do not shut down the power supply when saving any data into the memory built in the Sensor Controller, or the data may be corrupted. • While a fiber cable is not in use, be sure to attach the included protective cap to the connector of the fiber cable. Leaving it with the protective cap not attached may result in a malfunction due to the adhesion of foreign matter. • Make sure to initialize the Sensor Controller when connecting a different type Sensor Head from that which was connected the previous time the Sensor Controller was launched.
