Necessary conditions for alarm reset (refer to ① to ③ in figure2.)
Period ①: When a collector current over the OC level flows and the OFF command is input
Period ②: When a collector current over the OC level flows for a period more than the trip
① This represents the case when a failure-causing Fault lasts for a period more than

more than tALM. The alarm resets when the Vin turns OFF under no Fault conditions.
This represents the case when the Fault disappears and the Vin turns OFF within
tALM. The alarm resets after lasting for a period of the specified time tALM.
