Sync phase angle in °
Setting range:
0
– 360°
To have the currents of two supply units flowing in phase, you can set the phase angle
of the line cable current of an MP slave to that of an MP master in synchronization
mode. If the phase angle remains at the factory setting 0°, the phase angles are the
same. This means nearly the full power is available at the junctions of the respective
line cable systems.
The setting 180° reverses the current direction.

A phase shift of 180° is useful, if:
•
The current direction is reversed at junctions due to unfavorable cabling.
•
A re-cabling is to be prevented.
Runtime-related faults can be precisely adjusted with phase shifts that slightly vary
from 0º or 180º. This, however, is usually not required.
Sync timeout response
If the supply unit receives a faulty synchronization signal, or no signal at all, in the "MP
slave" synchronization mode, the fault response set here is executed.
The following settings are possible:
•
No response
•
Display only
•
Inhibit output stage
