Overload Alarm

869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
The Overload Alarm is used to alarm abnormal load increases that can indicate problems
with the process. An alarm is enabled only after the acceleration stage is complete and the
motor has entered the running or overload stage. Once enabled, the alarm is generated
when the average phase current exceeds the Pickup setting for the time delay specified by
the setting Pickup Delay. When the current has subsided, the alarm stays active for the
time specified by the setting Dropout Delay.
