(3) Status alarms
Alarm characters and the frequency setting may be alternately displayed on the LED in standard
monitor
mode. The following four types of characters may be displayed.
C ···When current exceeding the overcurrent stall level flows.
P ···When voltage exceeding the overvoltage stall level is generated.
L ···When 50% or more of the overload trip value is reached.
H ···When the temperature reaches the overheat protection alarm setting level.
Several alarms may also be displayed simultaneously.(" LC

The alarms will automatically go out when the alarm condition is removed.
(4) Trip information
The standard monitor mode trip display will be entered immediately when a trip occurs.
