Description
Normal operation
24 V DC power failure or WDT error
Flickers at 0.5-second intervals when the offset value or gain value being
used for compensation is within the setting range.
Flickers at 0.1-second intervals when the offset value or gain value being
used for compensation is out of the setting range (out of the temperature
input range or the gain value minus the offset value is smaller than +10°C).
In this case, the offset or gain value cannot be memorized.
Turns off when the offset/gain setting switch is positioned at SET
Communication data error (CRC error)
Station number, baud rate switch setting error
Indicates that the station number or baud rate switch setting was
changed while power was on.
CC-Link dedicated cable is affected by noise.
