Likely Cause of Condition and Possible Action

7

Low Battery Fault

Cause: The battery charge is not sufficient to allow safe

driving. It has fallen below 17V

Action

<

  Check battery connection and terminals. The

battery voltage should be similar when the
battery is on charge, and when it isn’t.

<

  Check that fuses have not blown, or circuit

breakers tripped.

<

  Replace battery if worn out or if capacity is

insufficient for the user’s needs.

Note:

 The wheelchair will behave sluggishly and the

Battery Gauge will flash indicating low battery voltage
prior to the display of this fault.

8

Overvoltage Fault

Cause: The battery voltage has exceeded 32V.
Action

<

  If this fault occurs during battery charging, the

battery charger is defective or incorrectly
adjusted.

<

  Check the battery chargers open circuit voltage

is in accordance with the battery manufacturers
limits, and is less than 32V.

Cause: The battery connector is making intermittent

contact when the wheelchair is stopped, or
travelling down a slope.

Action

<

  Check that the battery wiring and terminating is

secure.

9

CANL Fault

 (see Limp Mode below)

Cause: 1. An invalid voltage has been detected on the

DXBUS CANL line.

2. Communication is not possible using the CANL

wire.

Action

<

Check the continuity of the DXBUS cable.

<

  Check for shorts between DXBUS pins. An

open or short circuit on another DX Module
can cause this fault.
