Right (M2) Motor Fault
Cause: The connection from the PM right (M2) connector to its associated motor, or the
motor itself, is defective. The connection is either open or short circuit.
Action • Disconnect the right motor plug and check continuity between the motor pins
on M2.
• Ensure there is no continuity between motor and park brake terminals.
5
Left (MI) Park Brake Fault
Cause: The M1 plug connection to its associated Park brake is either open or short
circuit.
Action • Disconnect the M1 plug and check continuity between the two Positronic park
brake pins.
• Ensure there is no continuity between motor and park brake terminals.
6
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.
• Ensure there is no continuity between motor and park brake terminals.
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
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 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.
