The appearance of one or more alarms determines the tripping of the acoustic alarm; in these
conditions, the alarms in progress are displayed.
The acoustic alarm can be muted by means of the specific key.
The messages concerning the alarms are organised as follows: the alarm appears in capital block letters
on the top line of the display unit while the bottom line shows the operations to be carried out to reset
the alarm.
A detailed description of the signalling panel functions is given below:
a) Loop view of the UPS status:
the signalling panel displays messages at about every 5 seconds related to the operating status of
all main sections of the UPS.
If one or more alarms trip at the same time, the control logic gives a continuous beep and displays the
alarms in progress.
If the operator mutes the acoustic signal using the key provided, the Signalling will again display all
the UPS messages together with the alarms in progress.
The following are the alarms and signals displayed on the LCD.
