
1: Could be incorrectly recognized as short circuit depending on used load (ex.: lamp load). If detection is incorrect, disable the
parameter setting.

2: This function is valid only when “Hold/Clear priority” of the system parameter is set to “Via software“.

3: Some PLC does not support an idle mode.

4: The count is memorized every hour. When the power supply is turned on again, counting starts from the last value memorized.

5: Times for setting is set value x1000 times.
