Test mode functionality

Functionality

When the Test mode functionality TESTMODE function is activated, protection functions in the IED

are automatically blocked. It is then possible to unblock the protection functions individually from

the local HMI or the Parameter Setting tool 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.
