If the initialising tests are interrupted and an error code among those listed is displayed, e.g.
“LOCAL DIAGS ON BOARD “RBCO” 00080000, to reset the fault it is necessary to replace
the module that failed the test, in this case, RBC2. The code issued is used by COMAU to
identify the fault and can be mentioned for subsequent module repair.
DIAGNOSTIC LEVEL 3
The PC video emulator and programming terminal display show the controller error messages which differ
according to the fault detected. These error messages are on parallel stored in a file called ERROR.LOG,
resident in the controller memory which may be consulted if the message is erased from the display/PC
video emulator or if requiring to check which alarms have occurred previously. The error messages are in the
following form:
E.G: 28694 - 11 - DRIVE OFF Safety gates or Emergency stop
The meaning of the error message is the following:
28694 (consecutive alarm number); 11 (seriousness level); DRIVE OFF (effect on controller status) Safety
gates or Emergency stop (text of message with fault detected on the system)
Below is a list of the levels of seriousness of the system and their meaning:
