Click the LED reset button.
Stored LEDs, output contacts, and spontaneous fault displays are reset on the assigned device.
Acknowledgment of Stored Indications via Log
You can also initiate acknowledgment of stored indications by communicating through connected substation
automation technology. This can occur in conformance to standards (IEC 61850, IEC 60870-5-103) or via
configuration (mapping) of the LED reset input signal for any protocol. Stored LEDs, output contacts, and
spontaneous fault displays are reset.
NOTE

As long as there are no active unstored indications at the output contacts and configured LEDs, the
acknowledgment of stored indications resets the LEDs and output contacts.

Test Mode and Influence of Indications on Substation Automation Technology

If the test mode of the device or of individual functions is switched on, the SIPROTEC 5 device marks indica-
tions sent to substation automation technology station control system with an additional test bit. This test bit
makes it possible to determine that an indication was set during a test. Necessary reactions in normal opera-
tion on the basis of an indication can thus be suppressed.
