n 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 FX3GE 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.
Analog input/output
The analog input/output 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
adequate EMC precautions be 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 products or through a user’s program in
the FX3GE Series PLC main unit.

4. SPECIFICATIONS AND WIRING
DANGER 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.
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).
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.
Note that when an error occurs in a relay 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 the builtin programming connectors, power connectors or I/O connectors.
Failure to do so may result in wire damage/breakage or PLC failure.
• Even if the AC power supply causes an instantaneous power failure
for less than 10 ms, 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).
CAUTION WIRING PRECAUTIONS
• Connect the AC power supply to the dedicated terminals specified 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.
• Use class D grounding (grounding resistance of 100Ω or less) with
a wire of 2mm² or thicker on the grounding terminal of the FX3GE
Series main unit. However, do not connect the ground terminal at the
same point as a heavy electrical system.
• 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.
• Input/output wiring 50 to 100m (164'1" to 328'1") long will cause
almost no problems of noise, but, generally, the wiring length should
be less than 20m (65'7") to ensure the safety.
4.1 WIRING
n CABLE END TREATMENT AND TIGHTENING TORQUE
• For the terminals of FX3GE series PLC, M3 screws are used.
The electric wire ends should be treated as shown below.
• Tighten the screws to a torque of 0.5 to 0.8 N•m.
• Do not tighten terminal screws with a torque exceeding the
regulation torque.
• Failure to do so may cause equipment failures or malfunctions.

n INSTRUCTIONS FOR CONNECTING INPUT DEVICES
In the case of no-voltage contact The input current of this PLC is
5 to 7mA/24VDC. Use input devices applicable to this current. If
no-voltage contacts (switches) for large current are used, contact
failure may occur.
In the case of input device with built-in series diode The voltage
drop of the series diode should be approx. 4V or less. When lead
switches with a series LED are used, up to two switches can be
connected in series. Also make sure that the input current is over the
input-sensing level while the switches are ON.
In the case of input device with built-in parallel resistance Use a
device with a parallel resistance of 15kΩ or more. When the resistance
is less than 15kΩ, connect a bleeder resistance.
In the case of 2-wire proximity switch Use a two-wire proximity
switch whose leakage current is 1.5mA or less when the switch is off.
When the current is 1.5mA or more, connect a bleeder resistance.

n 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.
Inductive load Inductive loads generate large reverse electromotive
force between contacts at shutdown 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 20VA.
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.

the stationary current at activation. Make sure that the rush current
does not exceed the current corresponding to the maximum specified
resistance load.
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.
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.

n CAUTIONS IN EXTERNAL WIRING
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 in this product. 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.
DC CIRCUIT Connect a diode in parallel with the load. Use a diode
(for commutation) having the following specifications:
ItemStandard
Reverse Voltage5 to 10 times the load voltage
Forward CurrentLoad current or more

The following explains how to connect the built-in Ethernet to 10BASET/100BASE-TX networks. Pay close attention to safety and use the
built-in Ethernet properly.
Sufficient network knowledge and safety precautions are required
when installing 10BASE-T or 100BASE-TX networks. Consult a
specialist when connecting cable terminals or installing trunk line
cables, etc.
Use a connection cable conforming to the standards shown in this

n CAUTIONS REGARDING POWERING THE HUB, PLC AND
ETHERNET SIMULTANEOUSLY
On some hubs, for a fixed period of time immediately after powering
up, even if packets are sent from the Ethernet device, there are cases
when packets are not sent to the external device. In this case, create a
sequence program that waits a sufficient amount of time after powering
up before sending packets.

6. BUILT-IN ANALOG SPECIFICATIONS
AND WIRING
CAUTION WIRING PRECAUTIONS
• 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 observe the following precautions in order to prevent
any damage to the machinery or accidents due to abnormal data
written to the PLC under the influence of noise:
1. Do not bundle the power line or shield of the analog input/output
cable together with or lay it close to the maincircuit, high-voltage line,
or load line. Otherwise, noise disturbance and/or surge induction
are likely to take place. As a guideline, lay the control line at least
100mm (3.94”) or more away from the main circuit, high-voltage line,
or load line.
2. Ground the shield of the analog input/output cable at one point on
the signal receiving side. However, do not use common grounding
with heavy electrical systems.
• Make sure to properly wire to the terminal block (European type)
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.
Twist the end of strand wire and make sure that there are no loose
wires.
Do not solder-plate the electric wire ends.
Do not connect more than the specified number of wires or
electric wires of unspecified size.
Affix the electric wires so that neither the terminal block nor the
connected parts are directly stressed.
6.1 ANALOG INPUT TERMINAL BLOCK (EUROPEAN TYPE)

input wire and power supply wire, or short-circuiting of output wires
may result in serious damage. Before applying power, check that the
power supply and ground terminals are connected correctly and input/
output devices are wired properly.
NOTES The dielectric withstand voltage and insulation resistance
test of the PLC should be measured in accordance with the following
procedures.
1. Remove all input/output wires and power supply wires from the PLC.
2. Connect a crossing wire to each of the PLC terminals (power supply
terminal, input terminals and output terminals) except the ground
terminal.
3. For the dielectric withstand voltage test of each terminal, refer to the
generic specifications for the product.
Measure the dielectric withstand voltage and insulation resistance
between each terminal and the ground terminal. Dielectric withstand
voltage: 1.5kV AC or 500V for 1min (The terminals vary in dielectric

2. Running and stopping with general-purpose input
(RUN terminal)
Operation with one switch (RUN)
One of the input terminals X000 to X017 *1 of the main unit can be
used as a RUN input terminal by a parameter setting (refer to the figure
below). When the specified input terminal is turned on, the PLC starts.
When it is turned off, the PLC is started or stopped depending on the
state of the built-in RUN/STOP switch.

3. Starting and stopping by remote control from programming
software
The programming software has a function to forcibly start and stop the
PLC by remote control (remote RUN/STOP function). However, when
power is reapplied, the remote RUN/STOP function is disabled. The
RUN/STOP status is then determined by the RUN/STOP switch or
RUN terminal.
For details on the start and stop procedures with remote control from
programming software, see below.
n USE OF SEVERAL RUNNING/STOPPING METHODS
1. When the built-in RUN/STOP switch and the general-purpose
RUN terminal are used
(without remote running/stopping operation from the programming
software) The RUN/STOP status of the PLC is determined by the
conditions shown in the following table.
Condition of
Built-in RUN/STOP
Switch
RUN
STOP
Condition of General-Purpose
Input Terminal Specified as
RUN Terminal by Parameter
OFFRUN

Status of PLC
2. When the remote running/stopping operation from the
programming software is performed
For this operation, keep both the built-in RUN/STOP switch and the
general-purpose input RUN terminal in the STOP position. If the stop
command is given from the programming software after the PLC is
started by either the built-in RUN/STOP switch or the general-purpose
input RUN terminal, the PLC will be restored to the running status by
giving the RUN command from the programming software. This can
also be accomplished by setting the built-in RUN/STOP switch or the
general-purpose input RUN terminal to STOP and then to RUN.
n OPERATION AND TEST [POWER ON AND PLC RUNNING]
SELF-DIAGNOSTIC FUNCTION
When the PLC’s power is turned on, its self-diagnostic function starts
automatically. If there are no problems with the hardware, parameters
or program, the PLC will start and the RUN command is given (RUN
LED is lit). If any problems are found, the “ERR” LED flashes or lights.
TEST FUNCTIONS
Functions of the programming tool to turn on/off the PLC devices
and change the current values/settings are effective or ineffective
depending on the PLC status as shown below.
Change of current
values of timers,
counters, data
registers, extension
registers, extension
file registers and
file registers *4
Change of settings
of timers and
counters *5
1. Forcible ON/OFF
The forcible ON/OFF function is effective on the input relays (X), output relays
(Y), auxiliary relays (M), state (S), timers (T) and counters (C). On the display
module, the function cannot be operated for the input relays (X).
The forcible ON/OFF function can turn on or off the devices only for one scan.
While the PLC is running, the function is substantially effective in clearing the
current values of the timers (T), counters (C), data registers (D), index registers
(Z and V) and extension registers (R) and in controlling the SET/RST circuit and
self-retaining circuit. (The operation to forcibly turn on timers is effective only
when the timers are driven by the program.)
The results of forcible ON/OFF operation performed while the PLC in the
stopped state or performed for devices not used in the program are retained.
However, the results of the operation performed for the input relays (X) are not
retained because the relays refresh input even while the PLC is in the stopped
state. (They are updated according to the input terminal conditions.)
2. Since the current values may be changed according to MOV instruction in the
program and the operation results, the most recently obtained values are retained.
3. Only display modules can change the current value by the extension file register
test function.
4. The current values of the file registers stored in the program memory cannot be
monitored or tested on the display module.
5. Change of timer and counter settings. The settings of the timers (T) and counters
(C) can be changed only when the timers are driven by the program.

n BUILT-IN VARIABLE ANALOG POTENTIOMETER FUNCTION
The main unit has two built-in variable analog potentiometers (shown
in the figure below). The current value increases from 0 to 255 when a
variable analog potentiometer is turned clockwise.
The current value of each variable analog potentiometer is stored in
special data registers shown below.
9. MAINTENANCE
This PLC does not incorporate consumable parts that are factors in the
reduction of service life. However, the output relays (points of contact)
and batteries (option) have a limited life expectancy.
n PERIODIC INSPECTION - BATTERY LIFE, ETC.
1. Battery
Model FX3U-32BL battery: Standard life: 5 years (at ambient
temperature of 25°C (77°F))
2. Other devices
When inspecting the battery, check the following points.
Check that the temperature in the panel is not abnormally
increased by other heat generating bodies or direct sunlight.
Check that dust or conductive dust has not entered the panel.
Check for loosening of wiring and other abnormalities.
3. Battery Replacement
When the battery voltage drops while the PLC power is on, the “ALM”
LED on the panel is lit in red, and M8005 and M8006 (latch) are turned
on. The memory can be retained for about one month after the lamps
turn on. However, the operators may not immediately find the lamps to
be on. Prepare a new battery promptly, and replace the battery with the
new one.
n MAINTENANCE – PRODUCT LIFE OF RELAY CONTACTS
The product life of relay contacts varies considerably 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.

set value of the timer T1.
The setting range in this example using T1 (100ms timer)
is from 0 to 255 sec.
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 contacts used for Inductive loads, such as
contactors and solenoid valves, is 500,000 operations at 20VA. The
following table shows the approximate life of a relay based on the
results of an operation life test.

The product life of relay contacts becomes considerably shorter than
the above conditions when the rush overcurrent is shut down.
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.
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.
27
FX3GE QUICK START MANUAL
Mitsubishi Electric Automation, Inc.
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.
