Possible Cause and Action
Right (M2) Park Brake Fault
Cause: The M2 plug connection to its associated Park Brake is
either open or short circuit.
Action < Disconnect the M2 plug and check continuity between
the two Positronic Park Brake pins.
Action < Ensure there is no continuity between motor and park
brake terminals.
Cause: The Park Brake parameter has been set to 'dual' instead
of 'sngl'. Refer to the Programming section for guidance.
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.
Over voltage 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 charger's open circuit voltage is in
accordance with the battery manufacturer's limits,
and is less than 32V.
Cause: 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.
