7 Type disparity The controller and the base
board are not suitable for
the type of operation chosen
by the operator.
It is an internal fault. Replace the
controller.
8 HBT disparity The HBT status is verified
by the controller and the
base board. If a difference is
found between the two, this
alarm appears.
It is an internal fault. Replace the
controller.
9 Faulty RAM
The algorithm used to verify
the main memory detects an
error. The file is corrupt.
