Diagnostics
The DX System indicates its status in several ways:
•
Battery Warning conditions are shown on the
Battery Gauge
(if fitted). During
warning conditions the chair is usually able to drive normally.
•
Other warnings and fault conditions are shown as System Flash Codes (see
section 9.6) on the
System Status LED
, which is located on the Master Remote.
During fault conditions the chair will either not drive or drive slowly.
•
In addition, each DX Module has its own
Module Status LED
that flashes when
that module has a fault condition. DX Module Flash Codes can be different
from the DX System Flash Codes. Look in the manual of the DX Module in
question for more information.
Both warning conditions and fault conditions can be diagnosed with the Hand Held
Programmer or the Wizard.
9.1
Limp Mode
If the DX System detects a fault that does not demand the powerchair to be stopped
completely, it will go to 'Limp Mode'. This is a reduced speed mode that recognises
problems, but allows the powerchair user to drive slowly towards a safe environment
where the problem can be investigated.
Warning:
If the DX System is displaying a fault or the chair enters Limp Mode, do
not operate the powerchair except to reach a safe environment.
Proceed extremely carefully because the chair performance may be
significantly different. Have the chair serviced by an authorised service
agent.
9.2
Stuck Power Button
If the power button is pushed and not released, the DX System does not switch on
and the System Status LED flashes constantly.
•
If the power button is released within a few seconds, the System Status LED stops
flashing and the System starts up normally.
•
If the power button is not released within a few seconds, the system switches off.
