• Via binary input (170.0043 „>25 Measu. Only") initiate the measuring request.
The synchronism check must release closing (message „25 CloseRelease",
170.0049).
• If not, first check whether one of the aforenamed messages 170.2090 „25 V2>V1"
or 170.2091 „25 V2<V1" or 170.2094 „25 α2>α1" and 170.2095 „25 α2<α1"
is available in the spontaneous messages.
Messages „25 V2>V1" or „25 V2<V1" indicate that the magnitude (ratio) adap-
tation is incorrect. Check address 6x21 Balancing V1/V2 and recalculate the
adaptation factor.
The message „25 α2>α1" or „25 α2<α1" indicate that the phase relation of the
busbar voltage does not match the setting under address CONNECTIONof V2 (see
Section2.19.1). When measuring via a transformer, address 6x22 ANGLE
ADJUSTM. must also be checked. This must adapt the vector group. If these are
correct, there is probably a reverse polarity of the voltage transformer terminals V
• For the synchrocheck the program SYNC V1>V2< is set to YES (address 6x08)
and SYNC Funktion X = ASYN/SYNCHRON (address 16x).
• Open the VT mcb of the busbar voltage.
• Via binary input (170.0043 „>25 Measu. Only") initiate the measuring request.
There is no close release. If there is, the VT mcb for the busbar voltage is not allo-
cated. Check whether this is the required state, alternatively check the binary input
„>FAIL: BUS VT" (6510).
• Close the VT mcb of the busbar voltage is to be closed again.
• Open the circuit breaker.
• For the synchrocheck the program SYNC V1<V2> is set to YES (address 6x07) and
SYNC V1>V2< to NO (address 6x08).
• Via binary input (170.0043 „>25 Measu. Only") initiate the measuring request.
The synchronism check must release closing (message „25 CloseRelease",
170.0049). Otherwise check all voltage connections and the corresponding param-
eters again carefully as described in Section 2.19.1.
• Open the VT mcb of the feeder voltage.
• Via binary input (170.0043 „>25 Measu. Only") initiate the measuring request.
No close release is given.
• Close the VT mcb of the feeder voltage again.
Addresses 6x07 to 6x10 must be restored as they were changed for the test. If the
routing of the LEDs or signal relays was changed for the test, this must also be re-
stored.
