1.5 Backup Data

1.5.1 Data Backup

Data includes the Program, Comment, File Register (D1000 ~ D2499), and parameter data.
This will be stored as long as the EEPROM is not damaged. Mitsubishi Electric has
guaranteed a life cycle time of
operational writes to the EEPROM in excess of 10,000; however, due to temperature effects a
quantitative estimation cannot be given.

If the PLC has been powered ON for five minutes or more, the following device data will be
saved in the EEPROM at power-down:

S0~S127, M384 ~ M511, C16 ~ C31, C235 ~ C255 and D128 ~ D255.

If the PLC is powered ON for less than 5 minutes, the above data is not saved!

1.5.2 Capacitor backup

Only the RTC is backed up by the capacitor.

The capacitor backed memory will retain data for 10 days (Ambient temperature: 25ºC). The
capacitor requires 30 minutes to recharge upon power-up. There is no internal hardware reset

10,000

writes to the EEPROM memory. Users may experience

function, thus, after a 10day duration the RTC data may be unfixed and not reset to 0.

4.1 Wiring Techniques

1

Wiring for FX1S products has been designed to be safe and easy. If the user is concerned
about the correct installation of these products or associated products, please contact a
professional electrician who is trained to the local and national standards applicable to the
installation site.

4.2 Wiring Cautions

• Do not run input signals in the same multicore cable as output signals or allow them to
share the same wire.

• Do not lay I/O signal cables next to power cables or allow them to share the same trunking
duct. Low voltage cables should be reliably separated or insulated with regard to high
voltage cabling.

• Where I/O signal lines are used over an extended distance consideration for voltage drop
and noise interference should be made.

4.3 Power Supply

• When wiring an AC supply, the “Live” cable should be connected to the “L” terminal and

the “Neutral” cable should be connected to the “N” terminal. Do NOT connect the “Live”
wire to the “N” terminal, otherwise, the user may receive a dangerous shock upon
powerup.

• When wiring a DC supply, the “Live” cable should be connected to the “+” terminal and

the “Neutral” cable should be connected to the “-” terminal. Do NOT connect the “Live”
wire to the “-” terminal, otherwise, the user may receive a dangerous shock upon
powerup.

6.2.1 Product life of relay contacts

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

1

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 test results in table 6.2 were gathered from a 1 sec ON/OFF test cycle.
Please note that the over current induced by in-rush greatly reduces the relay contacts life.
The rated life for an inductive AC load such as a contactor or solenoid valve is 500,000
operations at 20VA.

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 "Output circuit configuration" below
in this section.

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 Section 6.1.

6-4

FX1S Series Programmable Controllers Outputs 6

6.2.2 Output circuit configuration

An internal protection circuit for the relays is not provided in the relay output circuit for 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.

1) DC load
Connect a diode in parallel with the load.

The diode (for commutation) must comply with the

Inductive load

following specifications.

6.3.1 Response Times

OFF times increase as the load current decreases.
For improved response times use a 'dummy' resistor, see Figure 6.4. If a response time of 0.5
ms or better is required when using 'light loads' use a 'dummy' resistor and ensure the signal
line has a current greater than 60mA/24V DC.

6.3.2 External wiring precaution

1) Contact protection circuit for inductive loads

Transistor outputs use internal zener diode (50V)
as protection circuitry. When driving the inductive
load with transistor output, a reverse-current
protection diode can be installed in parallel with the
load if necessary.
The reverse-current protection diode needs to satisfy the following specifications.

- Choose a commutating diode that has a reverse voltage strength over 5 - 10 times the
load voltage, and a forward current over the load current.

2) Mechanical Interlock
Ensure all loads are applied to the same side of

each PLC output, see previous figures. Loads
which should NEVER simultaneously operate
(e.g. direction control of a motor), because of a
critical safety situation, should not rely on the
PLC’s sequencing alone. Mechanical interlocks

MUST be fitted to all critical safety circuits. (See
