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
