manual switches

6.7.2.1

Preparation of the verification

Check the function settings on the local HMI under

Main menu/Settings/IED

Settings/Control/SMBRREC(79,0->1)/SMBRREC:1

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.

Decide if a synchronizing check function SESRSYN (25) shall be included in the
test.
