It must be checked that the speed of the 7VE61 and 7VE63 is influenced in the correct sense.

WARNING
Warning of faulty speed adjustment!
Non-observance of the following measures can result in death, personal injury or substantial prop-
erty damage.
²
If the speed adjustment is not carried out as you planned:
²
Abort immediately synchronization pressing the stop-input
²
Switch to manual operation
²
Shut down generator
²
Set up the recommended setpoint commands.
If the adjustment direction is correct, the command duration and the command intervals as well as the setting
parameters (e.g. df/dt) can be optimized. Here the RMS fault record is helpful, which shows very good the
transient condition behaviour due to the long recording time. If the main setting parameters are found, the
synchronization attempts are executed.
Synchronization attempts (dummy) are executed for over-frequency as well a for under-frequency in accord-
ance with the values of the parameters 6132 df ASYN f2>f1 and 6133 df ASYN f2<f1.
After successful checking of the frequency balance, the voltage balance is executed. The generator is brought
to approx. rated speed, the excitation is brought to a voltage outside the permissible synchronization voltage.
The synchronization function is initiated in the 7VE61 and 7VE63.
It must be checked that the voltage of the 7VE61 and 7VE63 is influenced in the correct sense.

WARNING
Warning of faulty voltage adjustment!
Non-observance of the following measures can result in death, personal injury or substantial prop-
erty damage.
²
If the voltage adjustment is not carried out as you planned:
²
Abort immediately synchronization pressing the stop-input
²
Switch to manual operation
²
Shut down generator
²
Set up the recommended setpoint commands.
If the adjustment direction is correct, the command duration and the command intervals as well as the setting
parameters (e.g. dU/dt) can be optimized.
Synchronization attempts (dummy) are executed for overvoltage as well as for undervoltage in accordance
with the values of the parameters 6130 dU ASYN U2>U1 and 6131 dU ASYN U2<U1.
The RMS value record is particularly suitable for checking the control behaviour. To do so, the fault recording is
to be set (parameter 401 WAVEFORMTRIGGER) to Save w. Pickup.
Figure 3-27 shows a record of a test operation with the synchronization function. The functioning of the oper-
ating time can be seen very well.
