This menu is displayed when the REAL TIME DATA is selected from MENU 1.
The cursor (→) is used to select the type of real time data the user wants to view,
such as, RECTIFIER DATA, RESERVE DATA, OUTPUT DATA, OTHER DATA
etc. The cursor (→) can be moved upward by the UP (↑ ) key, and can be moved
downward by the DOWN (↓ ) key. The selection is confirmed by pressing the
ENTER (← ┘ ), changing the menu to that at which the cursor is pointing.
If “EXIT” is selected (blinking instead of pointed by cursor), the screen will go
back to the MENU 1- the SELECT MENU.
5.5. Menu 4 – Historical Event Menu
This menu is displayed when HISTORICAL DATA is selected from MENU 1.
The records stored in EEPROM when abnormal events occur are displayed in this
menu. The record display starts with the date/ time stamp of the abnormal
condition, making it is possible for the user or maintenance personnel to trace the
occurrence. Seventy-seven (77) records can be stored in one EEPROM, which can
be increased to 154 records with a second EEPROM. These records will not be
erased by cutting off of the power supply or complete shutdown of the UPS, i.e.,
they will be kept in EEPROM until overwritten by the 78th (or the 155th) record.

Three records can be displayed concurrently on the screen. The records displayed

displayed records will move one record upward when the UP (↑ ) key is pressed,
and move one record downward when the DOWN (↓ ) key is pressed.
