13.5.5. Phase rotation check
This functionality checks the consistency of phase rotation i.e. of the wiring prior to commissioning.
Example: If the parameter ROT PH = ABC:
L1 (A)
L2 (B)L3 (C)
OK
L1 (A)
L3 (C)L2 (B)
NON OK
Display
12
or
12
depending on the non-compliant source
(Rotation check on sources
I
and
II
).
WARNING
Function available on both sources in case of 4NBL/4BL or 3NBL/3BL type of
network and only on source
I
in case of 41NBL or 42NBL network.
If the ROT PH parameter = - - -, the test is carried out when the two sources are present at the same time. It is
therefore recommended to have both sources present during commissioning.
WARNING
If the ROT CHECK parameter is set to NO, the product will not check the
consistency of the phase rotation. Make sure this option configuration is used
only when a different phase rotation order on the two sources does not impact
the load.
