Otto Bock A200 Service Instructions Manual page 49

No. Cause / Measures
(1)
Low battery voltage
The control system has detected a decline of the battery voltage to below 16 V.
Check the condition of the batteries and the connections to the control system. If the error per-
sists, there might be a defect in the power module.
If error code 2C02 applies, the control system creates a log about the frequency of
INfORMATION
switch-offs caused by low battery voltage.
(2)
Left motor disconnected
The control system has detected that the left motor is disconnected.
Check the left motor and its plug connections / check the cabling. If the error persists, there
might be a defect in the power module.
If the outputs of the left and right motors have been inverted during programming,
INfORMATION
this paragraph refers to the right motor. Please contact Otto Bock if you have any questions.
(3)
Error in the cabling of the left motor
The control system detects errors in the cabling to the left motor, especially if there is a short
circuit in the connection between the motor and battery.
Check the plug connections and cabling of the left motor. If the error persists, there might be a
defect in the power module.
If the outputs of the left and right motors have been inverted during programming,
INfORMATION
this paragraph refers to the right motor. Please contact Otto Bock if you have any questions.
(4)
Right motor disconnected
The control system has detected that the right motor is disconnected.
Check the right motor and its plug connections / check the cabling. If the error persists, there
might be a defect in the power module.
If the outputs of the left and right motors have been inverted during programming, this
INfORMATION
paragraph refers to the left motor. Please contact Otto Bock if you have any questions.
(5)
Error in the cabling of the right motor
The control system detects errors in the cabling to the right motor, especially if there is a short
circuit in the connection between the motor and battery.
Check the plug connections and cabling of the right motor. If the error persists, there might be
a defect in the power module.
If the outputs of the left and right motors have been inverted during programming, this
INfORMATION
paragraph refers to the left motor. Please contact Otto Bock if you have any questions.
(6)
Battery charger connected
The control system has detected that an external battery charger is connected.
Disconnect the battery charger. If the error persists, there might be a defect in the joystick module.
(7)
Possible joystick error
The control system detects problems with the system's own joystick or when there is a commu-
nication error between the joystick module and power module.
Replacement of the joystick and all subsequent work may only be carried out by per-
INfORMATION
sons authorised by the manufacturer of the wheelchair.
7100/7101: Loss of communication connection to the joystick. Check the joystick cable, flat
ribbon cable of the joystick, connections, and corresponding sockets.
7102: Loss of power supply to the joystick. Check the joystick cable, flat ribbon cable of the
joystick, connections, and corresponding sockets.
7103/7104: nternal error release. Check the joystick cable, flat ribbon cable of the joystick,
connections, and corresponding sockets. Verify, whether the cable is correctly connected to
the joystick and to the PCB.
