Installation Manual Issue 1
9.3 Fault indication
When a fault occurs, a flash code is displayed on both the master remote module and the compact
remote module. A flash code, which is displayed on the status indicator, is a number of flashes
separated by a 1.6 second gap; the number of flashes depends on the fault. For example, one flash
represents flash code one; two flashes represents flash code two, and so on.
Note :
Faults that affect the safety of the wheelchair will cause the wheelchair to stop, while less critical ones will be
indicated but allow the wheelchair to continue driving. Some faults will automatically clear when the fault
condition is removed (non-latched) while others are latched and must be cleared by turning the controller off,
waiting five seconds, then turning the system on again.
Faults are categorised according to their source — that is, there are local faults (those that relate to
the compact remote module), and there are system faults (those that relate to one or more system
modules). Local faults take priority with the compact remote module and so local faults will be
displayed on the compact remote module instead of system faults
if both local and system faults
occur at the same time.
When there is a local fault, the power button will flash red. All other indicators will be switched off. It is
possible that the rest of the system might not indicate a fault. All local faults (faults with the compact
remote module) are displayed as:
Flash Code 1: DX Module Fault
When there is a system fault, the power button will flash red. All other indicators will continue to
operate according to their role. The rest of the system will indicate the same fault or a related flash
code. System faults are displayed according to the flash codes described in the DX System Manual.

9.4 Dealing with compact remote module faults
1. If the compact remote module does not react to a command:
l
Check that the module is not in sleep mode (see 7.1.9 Lock mode 7.1.8 Sleep mode or
7.2.8 Sleep mode ).
l
Check that the module is not in locked mode (see 7.1.9 Lock mode or 7.2.9 Lock mode ).
2. If there is no power to the compact remote module:
l
Check the DXBUS connector is mated correctly.
l
Replace the DXBUS extension cable (if fitted).
l
Replace the compact remote module.
3. For all flash code 1 faults:
l
Check the DXBUS connector is mated correctly.
l
Check the profile setting:
o
If the Joystick Source parameter (see 6.4.1 User profile options ) of a pro-
grammable profile has been set up for a compact remote module (either RJM or
ACU), and the compact remote module cannot be seen by the system when oper-
ating in the profile, a flash code 1 will be displayed.
