-
the SFCCs give a class 1 level 2 caution and the ECAM display unit shows a failure message.
Reset is only possible on the ground.
(d) LVDT Excitation Power
Each flap channel monitors the correct LVDT excitation power. The internal secondary DC power supplies the LVDT excitation power. If the voltages or frequency are outside the specified limits:
-
the solenoids on the related valve block are de-energized
-
the POB locks the related motor
-
the SFCCs give a class 1 level 1 caution and the ECAM display unit shows a failure message
-
the flaps operate at half speed.
If the LVDT excitation power goes back to a value that is in the specified limits, the flaps will operate as normal.
