energized quantity (I) falls below the threshold setting [OC1], the element operation will
return to its reset stage after the time t(I) calculated in Equation (2.5-2).

Integration will be kept in timer [TOC1R].
The integration will start again when the energizing current
becomes larger than [OC1] within [TOC1R].

In the DT characteristic, the reset time is designed to be instant.
The integration will be deceased depending on the
[OC1-RTMS-*] reset characteristics.
