It is a display menu jump from MENU 1 when HISTORICAL DATA is selected.
The records stored in EEPROM when abnormal events happened are displayed in
this menu. The record display is started with the date and time stamped when the
abnormal condition happened. Therefore, it is possible for the user or
maintenance personnel to trace back what happen to the UPS in the past. 77
records can be stored in one EEPROM, can be increased to 154 records with 2
EEPROMs. All 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 forever
except over written by the 78th (or the 155th) records.
3 records can be displayed each time on the screen. The records displayed (once
this menu is popped) are the 3 most update records in the EEPROM. The
displayed records will move one record upward when the UP (
↑
) key is pressed,
and move one record downward when the DOWN (
↓
) key is pressed.
