1. SAFETY PRECAUTIONS
(Please be sure to read them before using the product.)
Please carefully read this manual before using the product and pay full attention to safety in order to
handle the product correctly.
Precautions given in this manual relate only to this product.
In this "1. SAFETY PRECAUTIONS," the safety precautions are ranked as "WARNING" and
"CAUTION."
Note that the CAUTION level may lead to serious consequences according to the circumstances.
Be sure to follow the instructions of both levels since they are important to personal safety.
Please be sure to pass this manual on to the end users.
In addition, please keep it in a safe place so that you can read it when needed.
[WIRING PRECAUTIONS]
●Be sure to block the power supply externally for all phases before wiring, otherwise an electric
shock or product damage may occur.
●Check the rated voltage and terminal layout of the product and correctly execute wiring for the
terminal block. Awrong rated power supply or wrong wiring may cause fires or breakdowns.
●Be careful not to let foreign matter such as sawdust or wire chips get inside the product. Fires,
breakdowns and malfunctions may occur.
WARNING
Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous
conditions, resulting in moderate or minor injury or only
material damage.
CAUTION
WARNING

4/43
[DESIGN PRECAUTIONS]
●An external safety circuit shall be installed to this product so that the whole system operates at
the safety side, even if an abnormality of an external power supply has an abnormality, or a
breakdown of this product. Erroneous output and malfunctions may cause an accident.
(1) Interlock circuits for conflicting operations such as forward/backward rotation or for
machine damage prevention such as upper/lower limits shall be configured outside of the
product.
(2) If this product detects a communication abnormality, it will stop operation and set all
outputs to OFF/HOLD. In addition, if an input/output control section has an abnormality
which cannot be detected by the microcomputer within this product, all outputs may be
turned on. In such case, an external fail-safe circuit or mechanism shall be installed for
this product so that the machine operates at the safe side.
(3) Outputs may be set to on or off at all times depending on a breakdown of an output circuit
transistor etc. For output signals which may cause serious accidents, an external
monitoring circuit shall be installed.
●A fuse or other safety circuits shall be installed externally since smoke/fires may occur if a load
current which is higher than the rated current or an over current by a load short circuit flows
continuously for a long time.
●A circuit of the external power supply for input/output circuits shall be configured so that the
power supply is turned on after the power supply for this product is turned on. If the external
power supply is turned on first, erroneous output or malfunctions may cause an accident.
●Control wires and power supply cables shall not be bundled with the main circuit and power
wires or be laid close to them. Separate them by 100 mm (3.9 in) or more. Noise may cause
malfunction.
●An output circuit with a margin in the rated current shall be selected, because large currents
(ten times greater than normal ones) may flow when the output is set to ON from OFF on
control of lamp load or others at the output circuit.
[INSTALLATION PRECAUTIONS]
●This product shall be used with the environmental specifications described in this user's
manual. If it used in an environment outside of the environmental specification range, electric
shocks, fires, malfunctions, product damage, or degradation may occur.
●Do not directly touch the conductive section of this product. Malfunctions and breakdowns may
occur.
CAUTION
WARNING
CAUTION

5/43
[STARTING/MAINTENANCE PRECAUTIONS]
●Do not touch terminals while the product is energized. An electric shock may occur.
●Be sure to block power supply externally for all phases before cleaning.
If all phases are not blocked, an electric shock may occur.
Tightening screws too much may damage the product causing it to fall.
●Do not disassemble or modify the product. Breakdowns, malfunctions, injuries, or fires may
occur. Also, that is prohibited by the Radio Law.
[DISPOSAL PRECAUTIONS]
●When this product is disposed of, it shall be handled as industrial waste.

5. RADIO UNIT INSTALLATION ENVIRONMENT
●Installation Environment
Install the Radio Unit avoiding the following environments.
•A place with direct sun light
•A place with extremely high humidity
•A place with corrosive or inflammable gases
•A place with intense electric field or ferromagnetic field occurrence
●Request on Installing Radio Unit
The Radio Unit transmits/receives data using radio waves. For using it with stable
communication status, install it paying attention on the following.
•Install the antennas of the units which communicate parallel to each other as much as
possible.
•Place metallic plates and concrete walls away from the antenna as far as possible (0.3 m
(11.8 in) at least).
•Install the antenna at a place 1.5 m (59.1 in) or higher from the floor to prevent impact from
moving objects (including human bodies).
•When communications are checked with a temporal installation, the unit shall be installed
on a control board or others which the unit is actually to be installed because
communications are affected by the environment near the fixing part such as metal and
concrete. (If the Radio Unit is installed in a metallic control board, install the flange head
antenna outside of the board.)
•The Radio Unit and antenna are indoor types.
If they are used outdoors, place them avoiding water (rain, fog, snow, etc.) and direct sun light
in a nonmetallic container such as a plastic case for outdoors.
Impact of water on the communication distance is assumed for electric wave characteristics.
In addition, if the plastic case has a metallic plate embedded, it shall not be used because it will
be an obstruction and significantly affect the communication distance.

6. SYSTEM CONFIGURATION
The system configuration example for the SWL31 Radio Series is described below.
The I/O addresses of the slave stations and extension units are closely allocated in the order of
smaller registered station numbers.
The bit I/O leading addresses' RXm and RYm depend on the parameters of the master station.
The word I/O leading addresses' RWr and RWw depend on the parameters of the master station.
* Refer to the I/O Correspondence Table in the next page.
* For the details of the parameter setting, refer to "2.4 GHz Band Radio Unit Setting Utility
(SWL31-UT1) User's Manual."
Refer to the figure below for the maximum bit points, word points, number of slave stations registered,
and number of extension units registered.

*1:The total of [P201_b to P240_b] and [P201_d to P240_d] is automatically calculated and displayed.
*2:When 21 slave stations are registered for one master station, [1] or more shall be set. For the star
communication (no relay), up to 1:20 communications are available.
*3:If the power of the master station is off or the LAN cable is disconnected, the data will not be cleared.
*4:When 000.0 is set, the timeout time is automatically calculated.
*5:This shall be set to Valid when the radio wave intensity is checked only with the radio units without the
Ethernet communications. If the Radio Test Mode is valid, the radio communications will be executed
regardless of the Ethernet communications.
