CAUTION

DANGER
 Form emergency shutdown circuits, interlock circuits or the like outside the
programmable controller. Failures in the programmable controller may result
in damage to the equipment or accidents.
 Use the I/O current with any I/O module within the maximum allowable limit.
Overcurrent flow can cause damage to the parts, resulting in accidents, fires,
or failures.
 Choose an external power supply with overvoltage and overcurrent protection
features.
 When the programmable controller smokes, gives off an offensive smell, or
otherwise misbehave, turn it off immediately and probe into the cause.
See Chapter 1 on page 8.
 An external supply voltage will cause electrical shock hazards if you mount or
demount the module or connect or disconnect the cable with the power switch
turned on and then touch the power terminal by accident. Also, this hardware
unit may be damaged due to a short circuit or noise. Be sure to switch off the
hardware unit before connecting or disconnecting it or its cable.
See Chapter 4 on page 34.
See Chapter 5 on page 43.
 Never touch the terminal block while the system is energized. Electrical
shock hazards can result if you touch the terminal block while the system is
energized.
See Chapter 5 on page 49.

CAUTION
 To prevent possible failures, house the programmable controller in a drip-proof
enclosure in cases where it is feared to be wetted with water.
See Chapter 1 on page 3.
 Even if the input voltage of the power supply module falls within a specified
range, assume it to be in an input power abnormality when it is close to the
upper or lower limit of the range, and call upon the power supply facility
manager for a checkup.
See Chapter 1 on page 4.
 Choose a power supply matching the rating of a module and connect it to that
module. Connecting an improper power supply to a module can cause the
module to fire.
 Parts containing gallium arsenide (GaAs) in a PC or LED are used in this
product. Gallium arsenide is designated as a harmful substance by law.
Use maximum discretion in handling and particularly scrapping the product.
Have a specialized agent dispose of the product as industrial waste.
 Use the same power supply for the external power supply (fed to the +V
terminal) of the S10mini output module and for the load power supply. Use of
different power supplies can cause malfunctioning.
 Do not use transceivers, cell phones or the like near the system.
Electromagnetic noise interference from such gear can cause the system to
malfunction.
See Chapter 1 on page 8.
 To avoid possible failures, allow for at least one second between turning-on
and turning-off of the power switch.
See Chapter 3 on page 25.
 Heat may build up inside the enclosure to such a degree that it will cause the
units to fail. Units may malfunction under the influence of electromagnetic
interference from the adjoining units. Allow specified clearances between the
enclosure and each unit and between the units to assure heat dissipation and
lessen electromagnetic interference.
 Temperature raises vary depending on the manner of installation. The
mounting intervals specified in the manual should be considered as
recommended values. Perform a test run upon mounting and measure the
temperature around the units to make sure that it is within allowable limits. If
the temperature is higher than permitted, increase the mounting intervals or
provide forced air cooling with a cooling fan.
See Chapter 4 on page 29.

CAUTION
 Dust deposited on the connector can result in degraded contact. Install and
wire the equipment immediately upon unpacking.
 Modules are susceptible to damage. Note the following points when installing
or removing modules.
• Check that the connectors are free from bent or broken pins and the pins are
aligned straight and are free from dust.
• Move modules along the vertical surface of the mount base as shown below.
If an inclined module is inserted or removed from the connector, connector
pints may be bent.
[Good example][Bad example]
See Chapter 4 on page 34.
 Have qualified technicians wire cables. Improper wiring can lead to fires,
failures, and electrical shock hazards.
See Chapter 5 on page 49.
 Modules may be damaged due to static electricity. Discharge static charges
from your body before setting switches, connecting or disconnecting the
cables, or inserting or removing the connectors.
See Chapter 9 on page 94.
 Even if the input voltage of the power supply module falls within a specified
range, assume it to be in an input power abnormality when it is close to the
upper or lower limit of the range, and call upon the power supply facility
manager for a checkup.
 Hot swapping of modules can lead to hardware or software destruction. Be
sure to replace the module with the power off.
See Chapter 9 on page 95.

PROHIBITION
 Do not install, wire, handle, or remake the programmable controller beyond
such an extent as may be defined in this manual. We will not be liable for
any damages to our programmable controller and ancillary equipment and for
physical injury arising out of such actions.
See Chapter 1 on page 9.
 Keep the insulating sheets in position to insulate the mount base from the
enclosure.
 Never insert fingers or foreign matter into the clearances between parts of the
connectors and mount base.
See Chapter 4 on page 32.
 Do not install, wire, handle, or remake the programmable controller beyond
such an extent as may be defined in this manual. We will not be liable for
any damages to our programmable controller and ancillary equipment and for
physical injury arising out of such actions.
 To prevent noise-caused malfunctioning, keep the 100 VAC/VDC cable and
the network cable at least 100 mm apart from each other, rather than bundle
them together.
See Chapter 5 on page 49.
PROHIBITION
 Do not disassemble the module.
See Chapter 4 on page 33.
 Except the CPU battery, the internal parts are not customer-serviceable. We
will not be liable for any damages to our programmable controller and ancillary
equipment and for physical injury arising out of such actions. If the module
should fail, replace it in its entirety.
See Chapter 9 on page 105.

REQUIREMENT
 Attach a fuse or circuit protector to the external power supply to protect
against short circuits. Use a circuit protector matching the rating of the power
supply.
 Verify the wiring before turning on the programmable controller.
 Do not shut down (turn off or reset) the programmable controller without
making sure that the peripheral equipment is off or will be unaffected by the
shutdown of the programmable controller.
 Memory contents can be corrupted by module failures. Be sure to back up
sensitive data.
See Chapter 1 on page 9.
 Secure the mount base to the predetermined vertical surface. If it is secured
to a horizontal surface, heat dissipation would be impeded, resulting in failures
or degraded parts due to temperature rises.
See Chapter 4 on page 32.
 Tighten the screws fully. Inadequately tightened screws can cause
malfunctioning, smoking, or firing.
 Damage to the module can result from static electricity. Discharge static
charges from your body before setting switches, connecting or disconnecting
the cables, or inserting or removing the connectors.
See Chapter 4 on page 35.
 A surge voltage may cause hardware units to malfunction or to be damaged.
When a coil, such as a relay, is connected to the PCs OK output circuit, install
a surge-absorbing diode or similar device. Use a diode with its peak inverse
voltage at least 10 times higher than the circuit voltage and with its forward
current equal to or higher than the load current.
See Chapter 5 on page 43.
 Before proceeding with power wiring, make sure that the power cable does not
have a voltage applied to it. Attach the terminal cover immediately upon
power wiring.
 Damage to the module can result from static electricity. Discharge static
charges from your body before setting switches, connecting or disconnecting
the cables, or inserting or removing the connectors.
 Wire the communications and power cables each separately, particularly at
least 300 mm apart from the power cables for inverters, motors, and power
controllers. Wire the communications and power cables in separate piping or
ducts.
See Chapter 5 on page 49.

REQUIREMENT
 Excessive accumulation of heat in the enclosure may cause a fire or hardware
failure. When the ambient temperature reaches 48°C or higher, the
maximum output current of the power supply module is limited. At 55°C, for
instance, it is limited to 5.85 A. Where this is very likely, install a cooling fan
in the enclosure or reduce the number of modules installed therein.
See Chapter 8 on page 88.
 If the battery is handled improperly, it may catch fire or explode. Some used
batteries may still have a considerable amount of charge. To deliver such
used batteries to a waste disposal site safely, follow the general rules for
collection, packing, and transportation. For concrete methods of packing and
transportation, consult with professionals of your local waste disposal
business.
See Chapter 9 on page 100.
REQUIREMENT
An electric shock may lead to a death or burn. Noise may cause the system to
malfunction. Ground the line ground (LG), frame ground (FG), and shield (SHD)
terminals, as described below.
• Leave the mount base insulated from the enclosure. To assure this, do not
remove the insulating sheet from the mount base.
• Ground the LG and FG terminals separately. The LG terminal is provided to
prevent intrusion of power supply noise, while FG and SHD are grounding
terminals that suppress intrusion of line noise into external interfaces for remote
I/O modules, interface modules, or other modules. To prevent mutual
interference, ground the LG and FG terminals separately.
• Connect the FG terminal on each module to the FG terminal on the mount
base. Have the FG terminal of any external interface line (such as a remote
I/O line or OPCN-1 line) grounded at a single point (terminating side) per line.
See Chapter 5 on page 42.

Notes for using Windows PC software
The Windows® PC (tool) software works with both S10mini and S10/2αSeries.
The user should note the following points:
For the PC software that can be used on the S10mini, see the next page titled “Controller Models
and Compatible Software Packages.”
1. CPMS or CPMSE load system -- No need to load the operating system
The S10mini operating system or OS (CPMS) is stored in flash memory in the CPU module.
Thus, the S10mini’s operating system needs to be handled differently from the operating
system (CPMS) of the S10/2αseries, as described below.
(1) Loading of the operating system is needed on S10/2αseries controllers, but it is not on
S10mini controllers. Do not load the OS from the CPMS or CPMSE load system.
Should such loading be carried out, reset the CPU module. The S10mini OS will then
boot.
(2) Since the S10mini control does not require loading of the operating system, the message
“LOAD OS” normally is not displayed by the indicator on the CPU module. Should
the message appear, turn the power off and then back on again at least 10 seconds later.
The CPU module will then be restored to normal, in which case reloading of the OS is
not required. As for the user programs and various settings, they need to be reloaded
or made again from scratch. If the message “LOAD OS” does not disappear, clear all
the memory by following “Clearing all the memory” on page 106. If the CPU module
is still not recovered, it is a hardware problem. Replace the CPU module.
2. Batch save/load feature -- Disallowing loading and saving of files between different
models
After saving files in a batch on the S10mini controller, do not load these backup files in a
batch to an S10/2αseries controller, or vice versa. If batch saving and loading like this is
performed, a controller malfunction may occurs.
3. RS-232C module (LQE060)
(1) LGB editing -- Unable to power down and then up again at the end of editing
At the end of LGB editing with the Windows PC software, the message “Reset or power
down and then on again” appears as a guidance. When working on the S10mini
controller, you can use only the Reset option. When you power down the controller
and then on again, the editing result becomes insignificant.
(2) System program loading -- No such loading required
Since the S10mini controller contains the system program for the RS-232C module in
flash memory within the module, loading of the system program is not required. If you
load it inadvertently, reset the CPU module. The S10mini system will then start up.
