1. DESIGN PRECAUTIONS

Reference

• 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 24V 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.

• 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 100mm (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.

FX3G Series Programmable Controllers

User's Manual - Hardware Edition

Caution for compliance with EC Directive

1. Installation in Enclosure

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

2. Caution for Analog Products in use

The analog products 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 devices, 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 recommends that shielded cables be used. If NO other EMC protection is provided, users
may experience temporary loss or accuracy between +10% / -10% in very heavy industrial areas.
However, Mitsubishi Electric suggests that if adequate EMC precautions are followed for the users complete
control system.

- Sensitive analog cables 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 accuracy can be improved by averaging the readings. This can be
achieved either through functions on the analog special adapters/boards/blocks or through a user's
program in the FX

3G Series PLC main unit.

6.5 Expansion of Main Unit

The extendibility of the main unit varies depending on the power supply type (AC power supply type or DC
power supply type). Select proper extension devices in accordance with the power supply type of the main
unit used.

In the case of AC power type main unit

The allowable extension to the AC power supply type main unit varies depending on used extension blocks
as described below.

Introduction

When extension of the above points 1 to 3 is carried out and further extension is required, determine whether
extension is possible using one of the following methods:
For details, refer to the following.

→ Refer to 6.6 Expansion of FX2N Series I/O Powered Extension Unit.

6.5.1 When adding input/output extension blocks using the 24V DC service power supply of the main unit

When extension is prohibited in the AC power supply type main unit due to restrictions in connection
described above, it is possible to add extension blocks using the 24V DC service power supply of the main
unit.
For adding extension blocks using the 24V DC service power supply, it is necessary to examine again
whether extension is possible for all of extension blocks selected in the preceding subsection and extension
blocks to be selected in this subsection.
Note that only up to two network-related special function blocks can be connected including extension to the
main unit.

1 Confirm the priority of all extension blocks to be connected to the main unit.

The priority is set to each extension block to be connected, and required to judge the possibility of
extension to the main unit. The priority is determined by the extension block type without regard to
the connection position.
