The definition of such a person or persons is as follows; a Any engineer who is responsible for the planning, design and construction of automatic equipment using the product associated with this manual should be of a competent nature, trained and qualified to the local and national standards required to fulfill that role.

These engineers should be fully aware of all aspects of safety with regards to automated equipment. These engineers should also be trained in the use and maintenance of the completed product. This includes being completely familiar with all associated documentation for the said product.

All maintenance should be carried out in accordance with established safety practices. The operators should also be familiar with documentation which is connected with the actual operation of the completed equipment.

Whenever any of the following symbols are encountered, its associated note must be read and understood. Each of the symbols used will now be listed with a brief description of its meaning.

Software warning 4 Indicates special care must be taken when using this element of software. Under no circumstances will Mitsubishi Electric be liable or responsible for any consequential damage that may arise as a result of the installation or use of this equipment.

All examples and diagrams shown in this manual are intended only as an aid to understanding the text, not to guarantee operation. Mitsubishi Electric will accept no responsibility for actual use of the product based on these illustrative examples.

Owing to the very great variety in possible application of this equipment, you must satisfy yourself as to its suitability for your specific application. Associated Manuals The following manuals are recomended as esential reference material for the correct operation of a FX1N series Programmable controller. Occupied points are shown in brackets for input and outputs. The value depends on the switch setting. AC, World spec, CE registered.


AC Wor ld spec. DC source transistor, CE registered. FX0N series extension units do not have UL certification. FX0N series extension units do not have CE certification. Only one special function board can be used at any time. The capacitor backed memory will retain programs for a maximum of 10 days, and requires 30 minutes to recharge upon power up.

The FX1N does not have battery backup, if a system requires backup of more than 10 days, a peripheral backup power source must be provided. Terminal layouts The following selection of terminal layouts are taken from the FX1N product range.

All layouts are diagrammatic and are only intended to aid the creation of wiring diagrams. When the products associated with this manual are used as a system or individually, they must be installed in a suitable enclosure.

The enclosure should be selected and installed in accordance to the local and national standards. Features table 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Top cover Direct mounting holes 4. Upper pot, D read from VR1.

Never mount them to the floor or ceiling of an enclosure. Units should not be installed in areas subject to the following conditions: Take special care not to allow debris to fall inside the unit during installation e.

Once installation is complete remove the protective paper band, to prevent overheating. To release, pull the spring loaded clips away from the rail and slide the unit up and off. Terminals screws should be tightened to between 0. Screw terminals must be secured to prevent a loose connection from causing a malfunction.

If during the installation of these products or associated products concern is felt, please contact a professional electrician who is trained to the local and national standards applicable to the installation site. Do not run input signals in the same multicore cable as output signals or allow them to share the same wire.

Low voltage cables should be reliably separated or insulated with regard to high voltage cabling. Always ensure that mounted units and blocks are kept as far as possible from high-voltage cables, high-voltage equipment and power equipment. Harxware greater detail, specifications and wiring examples for each optional unit, hardwwre see the relevant product manuals.

Always make sure the power is turned off, before installing a special function board. Only one board can be used at any one time, do not try to stack multiple boards. E Hzrdware A Special function or optional equipment board.

However Additional extension blocks can be powered from the main unit power hadware 4. Ground resistance must be less than ? Note that the ground cable must not be connected to the same ground as the power circuits.

Grounding is recommended but if a proper ground cannot be provided, the PLC will still operate correctly without being grounded.

When using a DC powered unit, the input circuit power supply should be used. If resistance Rp is less than the stated value, then add Rb. See equation 1 for Rb calculation. If the current leakage is greater than the stated value, then add Rb.

See equation 2 for Rb calculation.

Parallel LED Eqn 1: The following instructions are also not suitable. Do not use this terminal Fuse Surge absorbing Diode. Please note that the over current induced by in-rush greatly reduces the relay contacts service life. The rated life for an inductive AC load such as a contactor or solenoid valve isoperations at 20VA. For improved response times use a ‘dummy’ resistor, see the figure below. If a response time of 0. If a high speed response is required, a current of 10 – mA must be used.

Mechanical interlocks MUST be fitted to all safety critical circuits. Check the power LED is lit. Down load a small test program into the PLC. Verify the program to ensure it has been written to the PLC correctly. Check the output LEDs for operation. Check the previously down loaded program works correctly. During this testing stage take extreme care not to touch any live or hazardous parts. Check D for program scan time, units 0. LED is lit B Check for programming error.
