6005-145 Rev. A 1-24
FUSE/TEMP –Inverter fuse is blown or over temperature condition
exists.
OVERLOAD – output is overloaded by over 110%, 125% or 150%.
HIGH DC – the LED will light as long as the DC voltage is over
430VDC.
BAT LOW – the LED will light as long as the DC voltage is lower than
320VDC.
BAT LOW STOP – the LED will light as long as the DC voltage is lower
than 295VDC, inverter cannot start.
FAULT – the inverter is shutdown due to abnormal conditions such as
overload, short circuit, high DC, fuse over temperature, bypass
breaker on or emergency stop.
Since these LEDs are located behind the transparent window, the user can
see them clearly without opening the door.
D: Audible (buzzer) alarm: The user should not be expected to watch the ELI
all the time. Therefore, when abnormal conditions occur, an audible sound
should be emitted to warn the user to check the status of the ELI. The alarm
buzzer will beep under any one of the following conditions:
INVERTER IS OVERLOADED-
>110%, beep once / 3 seconds
>125%, beep once / second
>150%, beep twice / second
BACK- UP
>320VDC, beep once / 3 seconds
<320VDC, beep twice / second
<295VDC, no beeping
INVERTER IS SHORT CIRCUITED - beep continuously
FUSE BROKEN - beep continuously
HEAT SINK OVER TEMPERATURE - beep continuously
HIGH DC SHUTDOWN - beep continuously
BYPASS ON STOP - beep continuously
EMERGENCY STOP – (emergency power off) beep continuously
The buzzer will also beep once every time the inverter is switched on or
off to acknowledge to the user that his key is valid and accepted.
