5 Troubleshooting
5.1 OONAPU conditions
While driving, it is not possible to
switch between a non-Gyro Drive Profile and a Gyro Drive Profile, or
switch between Drive Profiles that have Different Gyro Profiles selected in their
Gyro Profile Select field (4.2.1.1), for example G1 and G2.
If a switch is made during driving, the chair will stop and an OONAPU condition will
occur. The joystick must be released to the centre before the chair will drive again.
Out Of Neutral At Power Up is a feature that prevents sudden and unexpected
powerchair movements if the joystick is out of the centre when the controller is turned
on or an inhibit condition is removed. For information on how an OONAPU condition is
shown, see the installation manual of the Master Remote used. For more information
on OONAPU in general, see section 9.3 of the DX System Manual.
5.2 Gyro Faults
If a Drive Profile is selected that is configured for Gyro operation, and the DX2-GYRO
module is not connected or gives faulty signals,
Gyro operation is disabled, and
The maximum speed of the chair is limited to the Gyro Fault Speed Limit (4.2.2.6)
that belongs to the currently selected Gyro Profile, and
The remote shows Flash Code 2 to indicate that there is a Gyro fault.
If the chair is driving at the time that the fault occurs, the chair decelerates to the
speed that is set with the Gyro Fault Speed Limit parameter.
If a Gyro fault occurs in a Drive Profile that is not configured for Gyro operation, the
chair will continue to drive normally and no fault code will be shown. For this reason it
is preferable to switch to a non-Gyro drive profile if a Gyro fault is present, because
the non-Gyro drive profile will drive normally and will not limit the speed to Gyro Fault
Speed Limit. This will probably perform better than continuing to drive with a Gyro-
enabled Drive Profile.
Gyro faults are reset with a power cycle only.

Warning:
Chairs that are tuned to operate with a Gyro may become unstable when
the Gyro control system is not in operation. Typically the Gyro system allows
much faster speeds than in non-Gyro operation.
To make sure that the chair does not become unstable without the
assistance of the Gyro control system, set the Gyro Fault Speed Limit
parameter to a value that prevents the chair from operating at speeds that
can make the chair unstable.
