Maintenance and Troubleshooting

Removing the MD from the machine configuration
In case a spare MD is not available and if the faulty MD is not able to communicate
with the CAN line, it is possible to remove the device from the machine configuration
in order to proceed with the job.
This requires a consequent change of the machine configuration as well as a change
of the devices logical address.
If this problem arises the 1-1801
“
Invalid configuration or MD address
” alarm
is
displayed when turning on the system, without changing any settings or MD
connections.
1. Check the integrity of the fuse for the MD which is not able to communicate.
If the fuse is blown, replace it.
2. Check the integrity of the CAN connection towards and from the faulty MD.
3. If the problem persists, disconnect the system from the power supply via the
battery disconnect switch.
4. Remove the fuse for the faulty MD but do not unplug the cable from the MD
as it is used to keep the CAN connection towards the other motors.
5. Power up the system via the battery disconnect switch
6. After the system has been started, a 1-1801
“
Invalid configuration or MD
address
” alarm
is displayed and an MD Addressing window is opened.
7. Press the
“
Change configuration
”
button and modify the machine
configuration in order to show the number of devices after removing the
faulty one, and confirm the setting.
8. Press the

”
button
