For a detailed overview of LED statuses, see "LED status indicators" (below).
– Alarms provide warning information. They do not trigger any response from the
system and do not need to be acknowledged.
– If a fault occurs, the converter shuts down and the "SF" LED on the Control Unit lights
up. The converter cannot be switched on again until the fault has been rectified. Once
the fault has been rectified, it must be acknowledged.
Alarm and fault numbers are displayed via the OP, STARTER, or a higher-level control
system. The online help function in STARTER contains detailed troubleshooting
information.
