Figure 8.11
Historical Event Menu Display
MENU 4 is reached by selecting HISTORICAL DATA on MENU 1. All abnormal events
are stored on the EEPROM and viewed through this menu based on the time each
event occurred. The record display starts with the date and time stamp allowing the user
or maintenance personnel to trace back that occurrence. A maximum of 77 records can
be
stored
in
one
EEPROM.
This
can
be
increased to 154 records with the addition of a second EEPROM. These records are
hard coded onto the EEPROM and will not be erased by cutting off the power supply or
during a complete shutdown of the ELI, i.e. they will be kept in the EEPROM forever
until they’re overwritten by the 78
th
(or the 155
th
) events.
The three most recent records are displayed at one time on the view screen. 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.
