Display Led Indicators - Salicru EQUINOX EQX 5000-2T Quick Manual

5.3. DISPLAY LED INDICATORS

The LEDs on the display will appear in one of three different
states: on, off, or flashing.
LED off
LED flashing
LED flashing
The inverter uses different combinations of LEDs to indicate dif-
ferent situations:
Status of the LEDs
20
Status of the
inverter
Sleep The inverter has no power.
The inverter has power and it is performing internal checks before
Internal check
starting up.
The inverter is generating and there are no warnings or error
Generation
messages.
The inverter is generating but there is an active warning or error
message:
- The date/time may not have been set correctly.
Generation
- Potential fluctuation in the DC input.
- Potential fluctuation in the mains frequency.
- Possible fan malfunction.
The inverter interrupts generation and goes into sleep mode due to
anomalies in the mains or power supply:
Fault - Insufficient DC input voltage.
- Mains undervoltage or overvoltage.
- Mains under-frequency or over-frequency.
The inverter interrupts generation and goes into sleep mode due to a
severe anomaly:
Fault
- The inverter's internal temperature is too high.
- Overvoltage in the DC power supply.
The inverter interrupts generation due to an error caused by one of the
following:
- DC bus overvoltage.
- Boost failure.
- Internal AC overcurrent.
Error
- IGBT protection.
- International communications failure.
- Internal relay failure.
- Internal memory failure.
- Short circuit in the inverter output.
EThe inverter interrupts generation due to a serious error caused by
one of the following:
- Low isolation impedance.
Error - High leakage current.
- DC injected into the mains.
- Overcurrent in the DC input.
- DC polarity inverted.
