Table 3.AA Phase Sequence Setting Parameters
➊ If auxiliary relays #2 and #3 are assigned to the communication (refer to page 5-16 ) they cannot be selected
here.
Phase Failure (Based on Voltage Measurement)
Function
A phase failure is recognized by measuring the voltages before the switchgear and thus with
the motor at standstill. (With phase failure protection where the phase currents are measured,
the motor first has to be switched on, although it cannot start with only two phases.)

Function
Factory setting Off
Tripping Delay
Factory setting 1 s
Output Relay ➊
Selection (relays) MR, AL, #1…#5
Factory setting MR
ATTENTION
!
The phase sequence of the motor supply can be monitored only at the
point of measurement (usually before the contactor). Exchanged leads
between this point and the motor cannot be recognized.
Function
