This chapter deals with the following topics:
– Precautions before starting
– Methodology
– Comau Customer Center
3.1 Precautions before starting
– Read carefully the instructions in Chap.2. - Maintenance prescriptions on page 19
3.2 Methodology
– Problem analysis
– Diagnosis messages
– Identification items and abbreviations for connectors, cables and modules
– Traceability for replacement purposes
– Replacing the components
3.2.1 Problem analysis
The C5G Control Unit delivers information about the system status using:
– LEDs, located on the modules and cards
– diagnosis messages, displayed through he programming terminal.
Depending on the plant condition, one or both means (LEDs, messages) may be useful
to detect possible faults:
– during the boot phase, the programming terminal is not active and it is necessary
to rely on the LEDs on the modules
– when the programming terminal is active, the Diagnosis messages delivered are
more efficient
– in all cases, in particular for the auxiliary circuit power supplies, LEDs represent the
most immediate diagnostic procedure
– the pins in the tables in Chap. Details about the C5G Control Unit on page 43 of
the “Technical specifications” manual allow to check the availability of the expected
corresponding signal
– for the connection among modules and further information about the circuits, refer
to the Control Unit
Circuit Diagram (ver. ACC1 and ACC3).
