Precautions for Use
About installation
• Use your cellular phone or PHS at least 1m away from the product main unit in operation,
transmission cables, and I/O cable. Otherwise, the system may malfunction.
• When connecting a connector or cable and mounting a module to the base unit, firmly fix it with
screws.
Insufficient screwing can cause failure or malfunction due to vibrations.
• Do not drop the device and modules, hit them, or give a strong shock on them.
Otherwise, failure may be caused.
About power supply wiring
• Separate the cables as far as possible from other cables. In particular, separate them at least
200mm from power lines.
• The size of the terminal screw is M3.5. Use an appropriate crimp-style terminal with a width of 7mm
or less for the M3.5 screw.
• Do not connect anything to the NC terminals.
About use of sample programs
• For the sample programs provided in the Operating Instructions, does not guarantee the operation.
The customer shall make operation check before using them.
To prevent accident from malfunctioning, confirm adequately before operating.
About battery replacement
• Manganese dry batteries, alkaline batteries, and lithium secondary batteries are not compatible in
voltage. Do not use them.
• The battery can be replaced during energization or non-energization. If replacing the battery during
non-energization, do it within 3 minutes. Leaving without battery for a long time causes the RAM
memory content to be lost.
• The battery LED (BAT) may light while the battery is removed, but this is not an error.
It will go off when voltage drop is detected correctly after the battery is mounted.
• Do not use those after three years from the date of manufacture.
About maintenance
• Place the module removed from the unit on a conductive mat or conductive bag (a bag containing a
spare board, etc.) on a grounded table.
Otherwise, parts can be damaged due to static electricity.
• Before touching the device or modules, touch a grounded metal part to discharge the static electricity
on your body. Otherwise, static electricity on your body can cause malfunction or failure.
• Wipe the dirt on the device or modules with a soft cloth.
For severe stains, use a cloth soaked with water and wrung out.
Leaving them stained may cause misjudgment or malfunction.
• Do not use benzene or thinner to remove stains on the device and modules.
It may cause deformation or discoloration of the device panel and modules.
• To keep the system normal and prevent unnecessary troubles, perform the daily inspection, periodic
inspection, and cleanup on your body.
