below.
Figure 12 shows the general test connection principle, which can be used during
testing. This description describes the test of the version intended for one bay.

Testing the synchronizing function

The voltage inputs used are:
UP3LN1 UL1, UL2 or UL3 line 1 voltage inputs on the IED
UP3BB1 Bus1 voltage input on the IED
Testing the frequency difference
The frequency difference test should verify that operation is achieved when the
frequency difference between bus and line is less than set value of FreqDiffMax
and above set value of FreqDiffMin. The test procedure below will depend on the
settings used. Input STARTSYN must be activated during the test.
FreqDiffMax = 50.2 Hz
FreqDiffMin = 50.01 Hz
