8.5.5 Selecting the IED blocked or IED test and blocked mode
The IED blocked mode and the IED test and blocked mode can be activated using the
LHMI. The yellow Start LED flashes when the device is in the IED blocked or IED
test and blocked mode. The green Ready LED flashes to indicate that the IED test and
blocked mode is activated. By default, the test mode can only be changed from the
LHMI. Activation by remote client is possible, see the technical manual.
The Ready LED also flashes if the IED detects a diagnostic failure.
Check the test mode setting and the protection relay's IRF alarm
contact status to find the reason of the failure.
The test mode can be used for simulated testing of functions and outputs without
providing current inputs. The IED blocked mode can be used to block the physical
outputs to the process.
