Caution for compliance with EC Directive

Installation in Enclosure

Programmable logic controllers are open-type devices that must be installed and used within conductive control boxes. Please use the

FX 3U Series programmable logic controllers while installed in conductive shielded control boxes. Please secure the control box lid to the control box (for conduction). Installation within a control box greatly affects the safety of the system and aids in shielding noise from the programmable logic controller.

Caution for Analog Products in use

The analog special adapters have been found to be compliant to the

European standards in the aforesaid manual and directive. However, for the very best performance from what are in fact delicate measuring and controlled output device Mitsubishi Electric would like to make the following points;

As analog devices are sensitive by nature, their use should be considered carefully. For users of proprietary cables (integral with sensors or actuators), these users should follow those manufacturers installation requirements.

Mitsubishi Electric recommend that shielded cables should be used.

If NO other EMC protection is provided, then users may experience temporary induced errors not exceeding +10 %/-10 % in very heavy industrial areas.

However, Mitsubishi Electric suggest that if adequate EMC precautions are followed with general good EMC practice for the users complete control system, users should expect normal errors as specified in this manual.

- Sensitive analog cable should not be laid in the same trunking or cable conduit as high voltage cabling. Where possible users should run analog cables separately.

- Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth loops are accidentally created.

- When reading analog values, EMC induced errors can be smoothed out by averaging the readings. This can be achieved either through functions on the analog special adapter/block or through a users program in the FX

Power supply/input/output specifications and examples of external wiring

As for the details of the power supply wiring and input/output wiring, refer to FX 3U Series User's Manual - Hardware Edition.

DESIGN

PRECAUTIONS

 Make sure to have the following safety circuits outside of the

PLC to ensure safe system operation even during external power supply problems or PLC failure.

Otherwise, malfunctions may cause serious accidents.

1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the equipment at the upper and lower positioning limits).

2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be disabled.

External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

3) Note that the output current of the 24 V DC service power supply varies depending on the model and the absence/ presence of extension blocks. If an overload occurs, the voltage automatically drops, inputs in the PLC are disabled, and all outputs are turned off.

External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

4) Note that when an error occurs in a relay, triac or transistor output device, the output could be held either on or off.

For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

DESIGN

PRECAUTIONS

 Do not bundle the control line together with or lay it close to the main circuit or power line. As a guideline, lay the control line at least 100 mm (3.94") or more away from the main circuit or power line.

Noise may cause malfunctions.

 Install module so that excessive force will not be applied to peripheral device connectors.

Failure to do so may result in wire damage/breakage or PLC failure.

Notes

 Simultaneously turn on and off the power supplies of the main unit and extension devices.

 Even if the AC power supply causes an instantaneous power failure for less than 10 ms, the PLC can continue to operate.

 Even if the DC power supply causes an instantaneous power failure for less than 5ms, the PLC can continue to operate.

 If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned off. When the power supply is restored, it will automatically restart (when the RUN input is on).

WIRING

PRECAUTIONS

 Make sure to cut off all phases of the power supply externally before installation or wiring work.

Failure to do so may cause electric shock or damage to the product.

WIRING

PRECAUTIONS

 Connect the AC power supply 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 burn out.

 Do not wire vacant terminals externally.

Doing so may damage the product.

 Perform class D grounding (grounding resistance: 100  or less) to the grounding terminal on the FX 3U PLC main unit with a wire 2 mm 2 or thicker.

Do not use common grounding with heavy electrical systems

(refer to section 3.3).

 When drilling screw holes or wiring, make sure cutting or wire debris does not enter the ventilation slits.

Failure to do so may cause fire, equipment failures or malfunctions.

 Make sure to properly wire to the terminal in accordance with the following precautions.

Failure to do so may cause electric shock, equipment failures, a short-circuit, wire breakage, malfunctions, or damage to the product.

- The disposal size of the cable end should follow the dimensions described in the manual.

- Tightening torque should follow the specifications in the manual.

Notes

 Input/output wiring 50 to 100 m (164’1” to 328’1”) long will cause almost no problems of noise, but, generally, the wiring length should be less than 20 m (65’7”) to ensure the safety.

 Extension cables are easily affected by noise. Lay the cables at a distance of at least 30 to 50 mm (1.19” to 1.97”) away from the PLC output and other power lines.

3.5.2

Life of relay output contact

The product life of relay contacts considerably varies depending on the load type used. Take care that loads generating reverse electromotive force or rush current may cause poor contact or deposition of contacts which may lead to considerable reduction of the contact product life.

1) Inductive load

Inductive loads generate large reverse electromotive force between contacts at shutdown which may cause arcing. At a fixed current consumption, as the power factor (phase between current and voltage) gets smaller, the arc energy gets larger.

The standard life of the contact used for Inductive loads, such as contactors and solenoid valves, is 500 thousand operations at

20 VA.

The following table shows the approximate life of the relay based on the results of our operation life test.

Test condition: 1 sec.ON / 1 sec.OFF.

Contact life

1 million times

2 hundred thousand times

The product life of relay contacts becomes considerably shorter than the above conditions when the rush overcurrent is shut down.

For countermeasures while using inductive loads,

refer to Subsection 3.5.4.

Some types of inductive loads generate rush current 5 to 15 times the stationary current at activation. Make sure that the rush current does not exceed the current corresponding to the maximum specified resistance load.

2) Lamp load

Lamp loads generally generate rush current 10 to 15 times the stationary current. Make sure that the rush current does not exceed the current corresponding to the maximum specified resistance load.

3) Capacitive load

Capacitive loads can generate rush current 20 to 40 times the stationary current. Make sure that the rush current does not exceed the current corresponding to the maximum specified resistance load. Capacitive loads such as capacitors may be present in electronic circuit loads including inverters.

For the maximum specified resistance load, refer to Subsection 3.5.1.

Cautions in external wiring

For cautions in external wiring, refer to the following manual.


Protection circuit for load short-circuiting

When a load connected to the output terminal short-circuits, the printed circuit board may be burnt out. Fit a protective fuse on the output circuit.

Protection circuit of contact when inductive load is used

An internal protection circuit for the relays is not provided for the relay output circuit. It is recommended to use inductive loads with built-in protection circuits. When using loads without built-in protection circuits, insert an external contact protection circuit, etc.

to reduce noise and extend the product life.

1) DC circuit

Connect a diode in parallel with the load.
