Handling Pop-up Trip and Alarm Messages

A trip or alarm message indicates that a potentially serious operating event has occurred. To address the event, take the following steps:

Step

Action

1

When the trip or alarm event message displays, press OK.

The display screen displays a message explaining the context of the trip.

2

After reading the explanatory message, take the remedial steps necessary to resolve the underlying condition that caused the trip or alarm.

3

After resolving the cause of the event, press OK to close the alarm pop-up or trip context.

4

If the event is latched, press the button for three seconds to reset the latched event and revert the Status bar color to green.

NOTE: You can bypass steps 3 and 4 by pressing the button while the pop-up is open. In this case, the pop-up is closed, the latched event is reset, and the Status bar color reverts to green.

You can view trip history and alarm history events by accessing Alarm/History in tree navigation mode.
