– The Controller has
switched to Low wind mode & has started a time delay period to allow the turbine
to stabilize in the new operating mode before re-checking the charge current.
Note: High/Low wind mode switching is inactive when the controller is in Stall
mode. In Stall mode, high wind mode will also be selected to prevent high transient
currents if the controller switches back to charge mode during high winds.

Battery voltage is below the minimum recommended level & is therefore seriously
discharged, any loads should be removed & the batteries recharged as soon as
possible to avoid permanent damage to the battery.

– The
internal components of the control unit have reached a higher than normal
temperature. The turbine will be stalled and the cooling fan will run until the
temperature has reduced to normal levels when the turbine will resume normal
operation. If this occurs, check that the controller housing vents are not obstructed.
The control unit has a built in cooling fan which will only operate when the internal
temperature of the control unit exceeds a pre-set level. This will only normally
operate during periods of high generated power levels.
