This function can be used only when the optional external input is present. The accumulated value, peak
value and bottom value can be reset remotely.

Accumulated value external reset: A function to reset the accumulated value when an input signal is
applied.
In accumulated increment mode, the accumulated value will reset to,
and increase from zero. In accumulated decrement mode, the
accumulated value will reset to, and decrease from the set value.

: When the accumulated value is memorized and each time the accumulated value external reset is activated, the memory device
(EEPROM) will be accessed. The maximum writable limit of the memory device is 1 million cycles and should be considered. The
total number of external input resets and accumulated value memorizations should not exceed 1 million.
