10.0 VISUAL AND AUDIBLE ALARMS
The EDP70 PLUS UPS is equipped with visual and audible alarms which indicate the status of the UPS to the
operator. The visual alarms are displayed on the LCD and the mimic panel.
10.1 Silencing Audible Alarm
The audible alarm sounds when the UPS is in an alarm condition. The sound is silenced by pressing the button
marked .
When pressed, the red warning light which is illuminated continuously starts to flash, providing an even clearer
indication of the alarm condition, even though the audible alarm has been silenced.
10.2 Mimic
The display mimic consists of a pictorial representation of the functional blocks in the EDP70 PLUS UPS. When the
system is in NORMAL OPERATING CONDITION the green indicators are illuminated continuously.
In the event of an ALARM condition the indicators start to flash identifying the part (or parts) of the system in alarm
(see figure 19).
Further information on the alarms can be obtained from the LCD by scrolling through the page headings using the
button (page right control) until the message on the display describes the functional block in the UPS
identified by the flashing LED(s).
The alarms can then be accessed using the (scrolling up) and (scrolling down) record buttons. This
procedure is described in detail in section 10.4.
10.3 Liquid Crystal Display
The display is a 40-character (2 line x 20 character) module which is back lit.
The messages describing the functioning of the system are accessed via the user switches (see figure 18).
