Flash
Fault source Meaning
Code
The battery voltage is too low: it has fallen below 17V.
The most probable cause of this fault is a loose battery terminal.
• Check the batteries, the battery terminals, the cables, the
fuses and the thermal circuit breakers
7 Low Battery
• Batteries may be empty: charge the batteries
• Batteries may be damaged or too small: replace the batteries
The battery voltage has exceeded 32V.
• The batteries may be overcharged.
• If driving downhill, slow down and turn on the lights (if fitted).
8
Over
Voltage
• Enable High Voltage Rollback (see also
2.2.4.3).
If this fault occurs during battery charging, the battery charger is
defective or not adjusted correctly.
• Check that the open circuit voltage of the battery charger is
in accordance with the limits of the battery manufacturer,
and is less than 32V.
If this fault occurs during regenerative braking (when stopping or
travelling down a slope) and the batteries are not full, the battery
connector may make intermittent contact. During a lost
connection the braking energy can not be routed towards the
battery, therefore the system voltage becomes too high.
• Check the battery cables and connectors.
DX BUS
cable fault:
An invalid voltage has been detected on the DX BUS CANH or
CANL line. This fault condition results in Limp Mode (see
9.1)
• Check the DX BUS cables for damage.
9 CANL wire
• Check that there is no short-circuit between the pins of the
DX BUS cable. An open-circuit or short-circuit on another DX
Module can cause this fault.
10 CANH wire
If the Hazard Lights were already switched on when the DX System
was turned on, sometimes Flash Code 10 occurs.
• Turn off the Hazard Lights, turn off the DX System then turn the
DX System on again.
The motor current has been at, or close to, current limit for longer
than the Stall Timeout parameter value.
• The motors may not be strong enough for the chosen route
(the route is too steep).
o Turn off the DX System, let it cool down, then turn it
back on again and choose another route.
11 Stall Timeout
• The wheels may be rubbing on the frame.
o Make sure that the wheels can turn freely.
• The motors may be faulty.
o Have the motor(s) checked by a service technician.
The data in the DX System for a DX Module is corrupt or
incompatible with that module.
Module
Mismatch
• Reprogram the DX System.
12
There is a compatibility problem between two or more
DX Modules in the DX System. The powerchair will be disabled.
• Consult your Dynamic Service Centre.
