IMPORTANT! After a temporary blocking of IGCTs, the PCS6000 attempts to reset the fault
and to restart. If the restart is successful, ie, the device does not trip again within a preset
time, the fault will be cleared automatically.
1. Select the alarm display of the remote control system.
IMPORTANT! DO NOT clear or reset the fault buffer/display at this stage!
2. Check the alarm display for other, possibly related error messages.
3. Identify the fault and make a logbook entry:
NOTE – Refer to section 10.4.1, Fault levels, page 111 and to "Appendix A09 Fault
handbook" for explanation of the fault messages and for instructions on fault finding
and troubleshooting.
4. Try to rectify the fault according to the instructions in the fault hand-book ("Appendix
A09 Fault handbook").
DANGER! For your own safety, follow exactly the instructions in the fault handbook
(Appendix A09 Fault handbook) for fault finding and troubleshooting. DO NOT attempt
any repair work on the PCS6000 beyond these instructions. Before starting to
troubleshoot, carefully read the warnings in section 10.1, Safety, page 109.
If the problem cannot be solved, contact the authorized service engineer. In case further
support is required contact the ABB Service Line.
For efficient troubleshooting, check for other, related fault messages and have the
