8.5 Start-Up Faults
During power on and initialization, the system goes through a series of checks to
prevent hardware failures which can occur from common wiring or installation errors. If
Faults are discovered during the start-up sequence,
LED1 (Charger) and LED2 (Inverter)
will both illuminate red
and will blink a specific quantity which correlates to the fault
type. Listed below are the fault types and the blink quantities associated with each of
the fault types. To clear the fault, press the system test button after problem was
diagnosed/repaired which initiates a new system start-up.
8.6 Charger Faults:
While the batteries are being charged, the system will continuously check for faults
as part of its diagnostic capabilities.
LED1 (Charger LED) will illuminate red
and will blink
a specific quantity which correlates to the fault type. Listed below are the fault types
and the blink quantities associated with each of the fault types. To clear the fault, press
the system test button after problem was diagnosed/repaired which initiates a new
system start-up.
E3MINI SERIES |
15
INCORRECT AC (LED1/LED2
–
1 Blink)
Indicates that the incoming AC voltage does not match the VOLTAGE SELECT JUMPER position.
Simply remove the jumper and connect to the correct location.
VOLTAGE SELECT JUMPER (LED1/LED2
–
2 Blinks)
Indicates that the VOLTAGE SELECT JUMPER is not inserted. Insert jumper to the correct location so
that the Incoming AC voltage matches the VOLTAGE SELECT JUMPER location.
TRANSFORMER WIRING (LED1/LED2
–
3 Blinks)
Indicates that the blue and yellow wires for the main transformer are reversed.
LOW BATTERY (LED1/LED2
–
4 Blinks)
Indicates that the battery voltage is incorrect or too low to start the system. Check the connectors
and wiring of the batteries and measure the DC voltages to ensure they are above 12V.
OVERLOAD (LED1/LED2
–
5 Blinks)
Indicates that there is too much load connected or there is a short circuit. Check the connected
load wiring and/or reduce the connected load to the power of the inverter’s rating.
INVERTER (LED1/LED2
–
6 Blinks)
Indicates that there is fault with the Inverter module.
BACKFEED (LED1/LED2
–
7 Blinks)
Indicates that there is an AC voltage back-feeding the output terminals. This fault means that the
E3MINI Series was wired incorrectly between the output terminal and the load(s).
VOLTAGE SELECT JUMPER (LED1
–
2 Blinks)
Indicates that the VOLTAGE SELECT JUMPER is not inserted. Insert jumper to the correct location so
that the Incoming AC voltage matches the VOLTAGE SELECT JUMPER.
OVER TEMPERATURE (LED1
–
1 Blink)
Indicates that the MOS
FET’s Heatsink temperature has exceeded its limits. This fault will clear itself
after it cools down so no reset is required.
