B:
Warning
LED’s-
When an abnormal condition occurs, these LED’s will illuminate
allowing the user to identify the fault. This will also allow the service
personnel the ability to troubleshoot the system. These LED’s are
described below:
•
RECT AC FAIL –
when the supply to the rectifier is outside of the
operating parameters. This not only applies to voltage range but also
when phase rotation is incorrect or the rectifier has been shutdown
(refer to
C: Status LED’s
).
•
RES AC FAIL –
supply to the reserve is outside of the operating
parameters. Supply voltage or frequency out of range (refer to
C:
Status LED’s
).
FUSE/TEMP –
inverter has shutdown due to inverter fuse open or
heat sink temperature above operating parameters.
OVERLOAD –
an overload condition has occurred on the output.
HIGH DC –
this LED will be lit as long as the DC voltage exceeds
430VDC.
BAT LOW –
this LED will be lit as long as the DC voltage is lower
than 320VDC.
BAT LOW STOP –
the LED will be lit as long as the DC voltage is
lower than 295VDC. The inverter will not activate until the DC voltage
is above this level.
FAULT –
the inverter has shutdown because an abnormal condition
has occurred. Possible conditions include overload, short circuit, high
DC shutdown, fuse/over temperature, bypass breaker on or
emergency stop (refer to
C: Status LED’s
).

C: Status LED’s-
24 LED’s represent the real-time information regarding the status of
the ELI system. These LED’s will aid in diagnosing and trouble
shooting abnormal conditions. The 24 LED’s represent the following:
•
•
•
•
INVERTER ON –
inverter is running.
INV STATIC SWITCH ON –
inverter static switch is active.
OUTPUT SHORT CIRCUIT –
ELI output is in a short circuit state.
FUSE/TEMP INV SHUTDOWN –
inverter has shutdown due to
inverter fuse open or heat sink temperature above operating
parameters.
INVERTER FAIL INV SHUTDOWN –
inverter has shutdown due to
inverter output voltage below tolerances.
BYPASS ON INV SHUTDOWN –
inverter has shutdown because the
bypass breaker has been activated while the inverter is supplying
power to the load.
HIGH DC BUSS INV SHUTDOWN –
inverter has shutdown because
the DC Bus voltage is outside of operating parameters while the
inverter is operating.
