USER'S MANUAL - Positioning Control Edition FX3U/FX3UC SERIES PROGRAMMABLE CONTROLLERS Transistor Output FX3UC Main Unit [Japanese Model (Sink Output)] Line Driver Output FX3U-2HSY-ADP www.DataSheet4U.com Safety Precautions (Read these precautions before using.) Before installing, operating, maintenance or inspecting this product, thoroughly read and understand this manual and the associated manuals. Also pay careful attention to handle the module properly and safety. This manual classifies the safety precautions into two categories: and . Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury. Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage. Depending on circumstances, procedures indicated by may also be linked to serious results. In any case, it is important to follow the directions for usage. Store this manual in a safe place so that you can take it out and read it whenever necessary. Always forward it to the end user. 1. DESIGN PRECAUTIONS Reference • Provide a safety circuit on the outside of the PLC so that the whole system operates to ensure the safety even when external power supply trouble or PLC failure occurs. Otherwise, malfunctions or output failures may result in an accident. 1) An emergency stop circuit, a protection circuit, an interlock circuit for opposite movements, such as normal and reverse rotations, and an interlock circuit for preventing damage to the machine at the upper and lower positioning limits should be configured on the outside of the PLC. 2) When the PLC CPU detects an error, such as a watch dog timer error, during self-diagnosis, all outputs are turned off. When an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be disabled. Design external circuits and mechanisms to ensure safe operations of the machine in such a case. 3) When some sort of error occurs in a relay, triac or transistor of the output unit, output may be kept on or off. For output signals that may lead to serious accidents, design external circuits and mechanisms to ensure safe operations of the machine in such cases. B-4 B-14 B-67 Reference • Do not bundle the control line together with the main circuit or power line. Do not lay the control line near them.As a rule, lay the control line at least 100mm(3.94") or more away from the main circuit or power line. Noise may cause malfunctions. • Install in a manner which prevents excessive force from being applied to the built-in connectors dedicated to programming, power connectors and I/O connectors. Failure to do so may result in wire breakage or failure of the PLC. B-4 B-14 B-67 (1) Safety Precautions (Read these precautions before using.) 2. WIRING PRECAUTIONS Reference • Cut off all phases of the power source externally before installation or wiring work in order to avoid electric shock or damage of product. • Make sure to attach the terminal cover offered as an accessory to the product before turning on the power or starting the operation after installation or wiring work. Failure to do so may cause electric shock. B-4 B-22 B-67 Reference • Connect the AC power supply wiring to the dedicated terminals described in this manual. If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will be burnt out. • Connect the DC power supply wiring to the dedicated terminals described in this manual. If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will be burnt out. • Do not wire vacant terminals externally. Doing so may damage the product. • Perform class D grounding (grounding resistance: 100Ω or less) to the grounding terminal in the FX3U Series main unit with a 2mm2 or thicker wire. Do not connect the grounding terminal at the same point as a heavy electrical system (refer to the manual of the PLC main unit). • Perform class D grounding (grounding resistance: 100Ω or less) to the grounding terminal in the FX3UC Series main unit with a wire as thick as possible. Do not connect the grounding terminal at the same point as a heavy electrical system (refer to the manual of the PLC main unit). • When drilling screw holes or wiring, cutting chips or wire chips should not enter ventilation slits. such an accident may cause fire, failures or malfunctions. • Use the product in such a status that excessive force is not applied on I/O connectors. Failure to do so may result in wire breakage or failure of the PLC. • Fit the I/O cables securely to the designated connectors. Contact failures may cause malfunctions. • Perform wiring properly to the FX3U Series main unit and FX0N/FX2N Series extension equipment of the terminal block type in accordance with the following precautions. Failure to do so may cause electric shock, short-circuit, wire breakage, or damages to the product. - The.
