4.11. MENU 10 – HISTORICAL DATA

<DATE/TIME/EVENTS> RUN:00YR00MO

2003/09/10 14:14 FUSE/OVERHEAT

This menu is selected from MENU 1, the SELECT MENU.

The records are stored in EEPROM when abnormal events occur and are displayed in this menu. The

record display begins with the date and time stamp of each abnormal event. The user or maintenance

personnel can trace back these events up to 77 records (which can be increased to 154 records with 2

EEPROMs). These records will not be erased by cutting off the power supply or by complete shutdown of the

converter, i.e. they will be kept in EEPROM forever unless over written by the 78th (or the 155th) record.

3 records can be displayed at a time on the screen. The records displayed are the 3 most recent 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. The abnormal conditions that caused the

events to be recorded, are listed below:

1. HIGH DC SHUTDOWN / SHORT CIRCUIT / FUSE/OVERHEAT

2. OVERLOAD SHUTDOWN / EMERGENCY STOP / INVERTER ABNORMAL

On the top right corner of the screen, the converter run time is displayed in year/month for the reference of

the user or maintenance personnel to estimate the time for maintenance.

The UP (?) or DOWN (?) key has no function in this menu. The screen will go back to MENU 1- the

SELECT menu, when ENTER (<+) is pressed.
