USER INTERFACE
7. User Interface
Overview
7.1. Graphic Display Module (GDM)
The primary user interface for configuration of the HiPerGuard MV UPS is via the Graphical Display
Module (GDM) which is mounted on the door of the PE120-1 enclosure. It allows local control of the
HiPerGuard MV UPS, shows the UPS block status, and provides access to the operating parameters and
event history.
The GDM has different screens and menus. The User can switch between them on the left side of the
GDM. On the right side of the GDM, the User can view product's main information (product number,
access level, language, etc.) and the current block status (Some of the major modes are Power
Conditioning, Inhibited, Independent, Bypass Isolate). The Start/Stop button is also placed at the
bottom right corner, as shown below with a status bar above it to indicate different operating
scenarios:
– White: Indicates that the block is stopped with no warning or fault.
– Yellow: Indicates that block is starting/stopping/showing a warning.
– Green: Indicates that the block is running.
– Red: Indicates block has a fault.
The product information, control button and the status bar are always visible on the right side of the
screen and on all pages.
To avoid an unintentional operation, after pressing the Start/Stop button, the GDM will show a
confirmation window in the middle of the screen and the message "Please confirm: STOP this single
‘BLOCK’. Remaining UPS capacity may not be sufficient to protect rated load, as shown in Figure 7.1.
The User can confirm the operation by pressing "START/STOP” on the confirmation window or by
pressing "Cancel" to close the window and return to the previous screen with no changes on the MV UPS
state. Please refer to section 7.1.4 for more information about the system Start/Stop (two or more UPSs
connected in hard-parallel).
The Reset button is placed on the bottom right side of the GDM screen below the Start/Stop button as
shown in Figure 7.2. After Pressing the Reset button, the GDM will show a Reset confirmation window
with the message “Please Select: RESET this single BLOCK” as illustrated in Figure 7.3. The User/
Operator can either confirm or dismiss the process by pressing the “RESET” or “Cancel” button on the
confirmation window respectively.
