9. Troubleshooting
This is a guide for troubleshooting problems that may arise in the installation and operation of Ingecon
®
μWind units.
It also explains how to perform simple operations such as component replacement and unit configuration.
Troubleshooting for the Ingecon
®
μWind unit must be performed by qualified personnel in compliance
with the general safety instructions in this manual.
9.1. LED messages
Some of the LEDs indicate some kind of problem in the wind farm installation.
9.1.1. Green LED
This is the LED that should light up in normal start-up and operating conditions, while the others remain off. It has
three modes:
1 second flash
This type of blinking indicates that the wind generator is feeding the right amount of voltage to the inverter and it
is about to start up. In this state, the inverter checks the grid parameters to feed current into the grid at the latter’s
precise voltage and frequency. This process takes about one minute.
3 second flash
Standby due to low wind level. Flashing every 3 seconds. This alarm is triggered when the wind generator does not
receive enough wind to supply the minimum voltage required by the inverter to inject power.
If this situation occurs on a day when the wind is very light, check the status of the generator and that it is correctly
connected.
Steady light
Inverter connected to the grid.
9.1.2. Orange LED
This is the LED which indicates that alarms have been set off in the inverter.
0.5 second flash
•
If accompanied by the message COMMS!!! on the display, means that communication has been lost. This
may be due to problems with the communications cable if the communications installation is fixed or because the
inverter is resetting, in which case the flashing will be momentary.
•
If the flashing is not accompanied by this message on the display, the problem is that the external fan is not
working correctly.
Check that no foreign bodies have entered the fan, preventing it turning. Ensure that an adequate flow of air arrives.
1 second flash
The internal fan is not working correctly.
Contact Ingeteam.
3 second flash
The inverter is in self-limiting mode because it has reached the maximum permissible temperature.
In this situation, check that the fans are running, that the air inlets and vents are free from obstacles, and that there
are no sources of intense heat near the inverter. If the problem persists, contact Ingeteam.
