Display of alarms and tables

The time-stamped history and event tables may be displayed on a PC through the communication network.

Embedded memory

Micrologic A and E trip units have a non-volatile memory that saves all data on alarms, histories, event

tables, counters and maintenance indicators even if power is lost.

Maintenance Indicators

Micrologic A and E trip units have indicators for, among others, the number of operating cycles, contact

wear and operating times (operating hours counter) of the PowerPact H-, J-, and L-frame circuit breakers.

It is possible to assign an alarm to the operating cycle counter to plan maintenance. The various

indicators can be used together with the trip histories to analyze the level of stresses the device has

been subjected to. The information provided by the indicators cannot be displayed on the Micrologic

trip unit LCD. It is displayed on the PC through the communication network.

Management of Installed Devices

Each circuit breaker equipped with a Micrologic 5 or 6 trip unit can be identified using the

communication network:

•

serial number

•

firmware version

•

hardware version

•

device name assigned by the user

This information together with that previously described provides a clear view of the state of the

installed devices.
