If the output current exceeds 110% of the set value,
the FREQUENCY display will show OCP (Over Current Protect); an alarm will sound; the
FAIL LED will flash; the PROTECT LED will light; and the VOLTAGE and CURRENT
displays will show the corresponding values at the time of overload.

limit value, the FREQUENCY display will show HI-A; an alarm will sound; the FAIL LED
will flash; and the VOLTAGE and CURRENT displays will show the corresponding values at
the time of overload.
Output Current Fell Below Lo-A Limit.
If the output current is less than the set low-
