ENERCON E-40 Operating Instructions
Page 84 of 96
10.2.1 Turbine aligns itself to the wind, but fails to start
The first thing to do is to check on the LC display which status message is given. If the status display is not flashing and the cause of the fault is no longer there, the
E-40 should resume operations after a few minutes, providing the wind speed is sufficient (more than 2 m/s), but does not exceed 30 m/s.
If the turbine still fails to start, the complete control system can be reset by pressing the "quit error" key. If the turbine still does not resume operations after approx. 3 minutes or after pressing the "quick start" key, the turbine should be stopped by actuating the start / stop switch and setting the main switch to OFF. After 2 or 3 unsuccessful attempts to reset and restart the turbine via acknowledgement key and main switch, the service department should be informed.
If a fault has occurred that could be acknowledged by a turbine reset, there may still be a malfunction in the turbine which must be eliminated. Therefore, if the same fault signal appears again repeatedly, you should contact the Service department.
Some faults can only be reseted when the cause of the fault has been eliminated and a service code is entered. In that case the LC display will flash. For better identification, these fault messages are marked with an asterisk. The fault has to be inspected by a serviceman who knows the service code and also has the necessary means to eliminate the cause of the fault.
10.2.2 Turbine does not align itself to the wind properly
It is important to check first whether the "manual / automatic" switch on the control cabinet is in the automatic mode (red signal lamp does not light), because otherwise an automatic yaw control is not possible. If the automatic yaw control is activated, the cause of the fault may be a faulty wind indicator. The cause of the fault should be identified and eliminated by Service personnel.
10.2.3 Turbine does not start although there is no apparent fault
If there is sufficient wind, the control system should be reset for at least 5 seconds by switching off the main switch. Before actuating the main switch the turbine must be stopped by setting the start / stop switch to "stop". After 5 seconds, switch on the main switch. If the turbine does not start automatically in four minutes at the latest, reset the control system once more and attempt to start it with the "quick start" button, after first checking the nacelle position and aligning it with the wind, if necesary.
If there is still no response, the Service department must be informed.
