Authorization

By default, Test mode and Control mode can only be changed from LHMI. It is
possible to write test mode by remote client, if it is needed in configuration. This is
done via LHMI only by setting the Remote test mode parameter via Tests/IED test/
Test mode. Remote operation is possible only when control position of the relay is in
remote position. Local and remote control can be selected with R/L button or via
Control function block in application configuration.
When using the Signal Monitoring tool to force online values, the following
conditions need to be met.
• Remote force is set to "All levels"
• Test mode is enabled
• Control position of the relay is in remote position
