• A switch or circuit breaker should be provided close to Digital Controller. The switch or circuit breaker
should be within easy reach of the operator, and must be marked as a disconnecting means for
Digital Controller.
• Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine, alcohol,
or any cleaners that contain these or other organic solvents. Deformation or discoloration may occur.
• Design the system (e.g., control panel) considering the 2 seconds of delay in setting the Digital
Controller's output after the power supply is turned ON.
• The output will turn OFF when you move to the Initial Setting Level. Take this into consideration when
performing control.
• The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when
frequently overwriting data, e.g., through communications.
• Use suitable tools when taking the Digital Controller apart for disposal. Sharp parts inside the Digital
Controller may cause injury.
• Do not connect cables to both the front-panel Setup Tool port and the top-panel Setup Tool port at the
same time. The Digital Controller may be damaged or may malfunction.
• Do not exceed the communications distance that is given in the specifications. Use the specified
communications cable.
• Do not turn the power supply to the Digital Controller ON or OFF while the USB-Serial Conversion
Cable is connected. The Digital Controller may malfunction.
