Parameter setting for bypass function with synchronization with overlap
Description
Control signal for contactor K1
Control signal for contactor K2
Control signal setting when p1267.0 = 1
Bypass function is initiated by the control signal
Signal source to provide the feedback signal of contactor K1
Signal source for contactor K2 feedback
For synchronization, the internal voltages are used.
Synchronizer activation is triggered by the bypass function.
