Preparation of the verification
1.
Check the function settings on the local HMI under
Main menu/Settings/IED
Settings/Control/SMBRREC(79,0->1)/1:SMBRREC
If any timer settings are reduced to speed up or facilitate the testing, they shall be
set to normal after testing. A temporary label on the IED can be a reminder to
restore normal settings after which a verification test should be performed.
2.
Decide if a synchronizing check function SESRSYN (25) shall be included in the
test.
