5.3.9.4 Disable OONAPU Faults
Parameter Possible Values Default Rev HHP Lite Std Adv
Disable OONAPU Faults No / Yes No A,C -
An Out Of Neutral At Power Up (OONAPU) fault occurs if the joystick is not in the
centre position when the DX System is switched on. This makes sure that the
powerchair does not suddenly start to drive when the DX System is switched on.
If an OONAPU fault occurs, the System Status LED flashes constantly. The powerchair
does not drive. If the joystick is returned to the centre
within 4 seconds, the OONAPU
fault disappears and the powerchair can drive normally. If the joystick is not returned
to the centre within 4 seconds, the OONAPU fault will become a latching fault. To
clear a latching fault, the user must switch the DX System off and then on again.
If Disable OONAPU Faults has the value 'Yes', the user has unlimited time to return the
joystick to the centre. The powerchair will still not drive until the joystick is returned to
the centre, but the OONAPU fault will never become a latching fault.
Parameter
Value
Result
No
The OONAPU fault becomes a latching fault
after 4 seconds. The user must switch off the
DX System to clear a latching fault.
Yes
The OONAPU fault never becomes a latching
fault. As soon as the joystick is returned to the
centre the powerchair is ready to drive.
Users who have difficulty to release the joystick to the centre can also benefit from an
increased
Neutral Maximum (see 5.3.9.3) or an increased Drive Delay After Power-up
(see
5.3.9.6) setting.
