Replace corresponding contactors and plug the elements again. |
| E09 | Max. time of the balance tank water filling exceeded.Not Autoresettable. | The max opening time (30’) of the loading electrovalve of the balance tank has been reached | Make sure that the sensors of water level of the balance tank work properlyMake sure that the discharge hole has been left open.Check a possible water leakage in the hydraulic circuit. |
| E010 | Balance Tank Water levels signals are incompatibles.Autoresettable. | Water level sensors are sending incompatible signals. | Check position of the level sensors or replace them if they are malfunctioning. |
| E011 | Water level in the balance tank is below safety sensor. Autoresettable. | Some function is trying to be activated before the minimum level inside the balance tank has been reached (or when working, the level is below the safety sensor). | Make sure that the loading electrovalve is open and works properly. Make sure there’s no obstruction in the water charging circuit. Verify there’s no water leakage in the hydraulic circuit. |
