9.4 Dealing with compact remote module faults
9.1 OONAPU
OONAPU (“Out Of Neutral At Power Up”) is a safety feature that
prevents accidental movement of the wheelchair, either when powering
up, or when the wheelchair comes out of an inhibit state.
OONAPU warning
If the system is powered on (or comes out of an inhibit state) while the
joystick is not in the centre position, an OONAPU warning is displayed.
Figure 34: OONAPU sequence
During an OONAPU warning, the information display LEDs will flash continually (all on, followed by all
off) to alert the user, and the wheelchair will not drive. If the joystick is returned to the centre position
within five seconds, the warning will clear and the wheelchair will drive normally.
OONAPU fault
However, if the joystick remains out of neutral for longer than five seconds, an OONAPU fault will
occur (see note below); the fault is displayed by the status indicator flashing red, and the wheelchair
will not drive. To clear the fault, return the joystick to the neutral position and power the unit off and
then on again.
Note
:
An OONAPU fault will not be displayed if the Wizard parameter
Disable OONAPU Faults
is set to
Yes
.
An OONAPU fault will not occur if the active remote module is a DX2-ACU. Instead, if the DX2-ACU's joystick
remains out of neutral for longer than five seconds, the OONAPU warning will continue to be displayed.
9.2 Drive inhibit indication
When a wheelchair is in a drive inhibit state, the information display
switches off, and the mode button flashes at a rate of on for ½ second,
off for ½ second.
This sequence continues for the duration of the drive inhibit.

Note
:
Apart from the information display and mode button, the drive inhibit indication described above does not affect
any other indicators - all other indicators will continue to operate as normal.
