10 PREVENTIVE AND CORRECTIVE MAINTENANCE
10.3.2.3 Standard troubleshooting procedure
If a fault shuts down the drive, proceed as follows:
10.3.3 LEDs and switches on circuit boards and I/O devices
The following section provides an overview of the meaning of LEDs and
switches of the main circuit boards and I/O modules. The LEDs presented
in the following section can be checked easily while the auxiliary voltage
is switched on without having to remove covers first. The LEDs provide
information on the status of the devices and can be used for
diagnostic purposes.
1) DO NOT switch off the auxiliary supply voltage or try to reset a
fault message before all information at the time of the
occurrence of the fault condition has been saved.
2) Select the fault history display on the control panel, but do not
clear the buffer now!
See “8 Operation” on page 173.
3) Identify the fault and make a logbook entry.
4) Save the content of the data logger when a PC is available
which has the Drive Composer/Startup tool installed.
The data logger provides information (eg, waveforms of
voltage, current, torque) for efficient troubleshooting.
5) Contact ABB service if a fault cannot be rectified.
When calling ABB service, it is recommended to have the
following data available at the time when the fault occurred:
• Operating, ambient and load conditions
• Unusual events
6) After the fault has been rectified, start the drive as described
in “8.9 Starting the drive” on page 189.
