Figure 5-32:Measurement-value display
Note
The "Phase currents" display always shows the currents in the supply
cable. That is, if the soft starter is operated in the "Inside delta circuit"
circuit type, the currents measured internally by the soft starter are
extrapolated to the supply cable current (phase current) by a factor of 1.73
and displayed.
Due to asymmetries, the phase currents in the inside delta circuit may
deviate from the currents running through the supply cables.
Note
When using the 3RW44 soft starter in an IT system with ground fault
monitoring: 3RW44, product version
≤ *E06* and the PROFIBUS DP
communication module may not be used in this network configuration.
3RW44 soft starters as of product version *E07* can be used in
combination with the PROFIBUS DP communication module. However,
the phase voltage values (UL-N) and phase-to-phase voltage values (UL-
L) may be displayed incorrectly on the measurement-value display of the
3RW44.
