7 Maintenance and Repair

The Distribution Unit is maintenance free.

A repair is constrained to the exchange of the PCB‘s:

I/O PCB Identnumber 138--118.101

138--118.101 E10

Interface PCB Identnumber 138--118.103

138--118.100 E10

Operation during a repair can only be performed when the

CAN--bus is terminated.

It is absolute necessary that the CAN--bus is terminated

correctly on both ends.

If there is no terminator by jumpers within the respective

devices, than each CAN--bus (CAN1 and CAN2) has to be

terminated by, in total 4 resistors (each 120Ohm) from

CAN--low to CAN--high

Faults within the connected compass are not indicated. The have to be researched at

the display of the respective compass.

7.1 Error indication

An error is displayed by a blinking “ERRO”.
