6.6 EVENTS (ALARMS AND MESSAGES)
Each of the following listed events can be displayed on the LCD screen or on PC where the
ARGUS/JumpManager - Control Network is installed.
Alarms and Messages are differently specified because the alarms are indicating an
abnormal functioning of the UPS (which are additionally signaled with the LED alarm and
acoustically with the buzzer), while the messages indicate the various states of operation of
the UPS (stored in the events list, but no activating the LED alarm and the buzzer).
When in the alarms mode, the LCD screen displays a time ordered sequence of
screens corresponding to the last 256 alarms and messages, each screen indicating:
The number of the event (255 = the most recent).
The date and time when the event occurred.
The standard code and the status word.
An explicit text description of the events.
