Diagnostics
Diagnostic information is provided to enable a fault in the system to be identified and localised to a major component; e.g. motor. The following system diagnostics are provided:
Flash code sequence
1.
Low battery voltage fault. "__"__"__
2.
High battery voltage fault. ""__""__""__
3.
Left motor (or connection) fault.
"""__"""__
4.
Right motor (or connection) fault.
""""__""""__
5.
Left or right electromagnetic brake (or connection) fault.
6.
Controller fault.
7.
Motor stalled or joystick out of neutral time out """""""__"""""""__
"""""__"""""__
""""""__""""""__
where """ is a flash and "_" is a pause.
In the event of a system fault, the diagnostic indications are displayed by the battery gauge flashing. Faults are
encoded as one (for a low battery voltage fault) to seven (for a motor stalled or joystick out of neutral time out
fault) and displayed by flashing all LED's the number of items given by the fault code. The flash sequence (one
to seven) is followed by a long off period (2 seconds).
All faults latch, disabling the controller, and require the controller to be turned off then on again even if the source
of the fault is removed.
