7. MONITORING PANEL WITH LCD TOUCH
SCREEN.
This chapter describes the functions and instructions for opera-
tion of the monitoring panel with LCD touch screen, including
detailed information on the menus, warning screens and list of
alarms from the UPS.
7.1. INTRODUCTION.
Physically, the monitoring panel with LCD touch screen and
static bypass are part of the same unit as a module, although
they are individual entities with their own functionalities.
Through the LCD panel you can operate and control the UPS,
check all measurements and parameters, equipment status and
batteries, and historical and event logs. The two monitoring
panels available are shown in Fig. 41
Monitoring panel installed in sub-racks of 2 and 4 slots.
Monitoring panel installed in the sub-rack of 6 slots.

Monitoring panels with LCD touch screen.
Basically the LCD monitoring panel is divided into three func-
tional areas:
•
LCD touch screen with structured menus.
•
Flowchart of power LEDs and "Status" indicator and audible
alarm.
The flowchart is only available in the sub-racks of six
slots and it is information that appears replicated in the
"Cabinet" menu of the touch screen.
Additionally each power module has its own energy
flowchart, but obviously without the bypass and output
indicators.
The "Status" LED and acoustic alarm are present in all
sub-racks.
•
EPO emergency stop push button and function keys.
The EPO push button with the protective cover is avail-
able on all equipments.
The BYP, INV, and MUTE shortcut keys are only avail-
able in six-slot sub-racks.
For further information see Tab. 12.
