Before You Start
Operating environment (Use the unit within the range of the general specifications when
installing)
* Ambient temperature: 0 to +55°C
* Ambient humidity: 10 to 95 % RH (at 25 °C, non-condensing)
* For use in pollution Degree 2 environment.
* Do not use the unit in the following environments.
- Direct sunlight
- Sudden temperature changes causing condensation.
- Inflammable or corrosive gas.
- Excessive airborne dust, metal particles or saline matter.
- Benzine, paint thinner, alcohol or other organic solvents or strong alkaline solutions such as ammonia
or caustic soda.
- Direct vibration, shock or direct drop of water.
- Influence from power transmission lines, high voltage equipment, power cables, power equipment,
radio transmitters, or any other equipment that would generate high switching surges.(100 mm or more)
Static electricity
- Do not touch connector pins directly to prevent static electricity from causing damage.
- Always rid yourself of any static electricity before handling this product.
Power supply
- Use a power supply wire that is twisted.
- The unit has sufficient noise immunity against the noise generated on the power line. However, it is
recommended to take measures for reducing noise such as using an isolating transformer before
supplying the power.
- Allocate an independent wiring for each power supplying line, input/output device and operating device.
- If using a power supply without a protective circuit, power should be supplied through a protective
element such as fuse. If an incorrect voltage is directly applied, the internal circuit may be damaged or
destroyed.
- Be sure to supply power to a control and an expansion unit from a single power supply. Turning on/off
of the power of all the units must be conducted simultaneously.
Power supply sequence
- Have the power supply sequence such that the power supply of the control unit turns off before the
power supply for input and output. If the input/output power supply is turned off before the control unit,
or if the control unit is not shut off momentarily, the controller detects change of input level, and might
conduct an unexpected operation.
Before turning on the power
When turning on the power for the first time, be sure to take the precautions given below.
- When performing installation, check to make sure that there are no scraps of wiring, particularly
conductive fragments, adhering to the unit.
- Verify that the power supply wiring, I/O wiring, and power supply voltage are all correct.
- Sufficiently tighten the installation screws and terminal screws.
- Set the mode selector to PROG. mode.
Before entering a program
Be sure to perform a program clear operation before entering a program. Refer to the respective tool
software manuals for the details of the operation procedure. (Tool software: FPWIN Pro, FPWIN GR)
Request concerning program storage
To prevent the accidental loss of programs, the user should consider the following measures.
- Drafting of documents
To avoid accidentally losing programs, destroying files, or overwriting the contents of files, documents
should be printed out and then saved.
- Specifying the password carefully.
The password setting is designed to avoid programs being accidentally overwritten. If the password is
forgotten, however, it will be impossible to overwrite the program even if you want to. Also, if a password
is forcibly bypassed, the program is deleted. When specifying the password, note it in the specifications
manual or in another safe location in case it is forgotten at some point.
