Functionality

When the Test mode functionality TESTMODE is activated, all the functions in the IED are
automatically blocked. Activated TESTMODE is indicating by a flashing yellow LED on the local HMI.
It is then possible to unblock every function(s) individually from the local HMI to perform required
tests.
When leaving TESTMODE, all blockings are removed and the IED resumes normal operation.
However, if during TESTMODE operation, power is removed and later restored, the IED will remain
in TESTMODE with the same protection functions blocked or unblocked as before the power was
removed. All testing will be done with actually set and configured values within the IED. No settings
will be changed, thus mistakes are avoided.
Forcing of binary output signals is only possible when the IED is in test mode.
