3.7.6 Using OL Warning and Alarm Output Signals
This section describes how to wire and use photocoupler output signals OLWRN (over-
load warning) and OL (overload alarm).
These two output signals are output when operation under the rated current or more con-
tinues for a certain period of time. The overload warning signal is output in 20% of the
time required to output the overload alarm signal.

status:
Circuit is closed or signal is at low level. Normal state
OFF
status:
Circuit is open or signal is at high level. Warning or alarm state
