Description, Explanations
Trips the motor depending of the trip class within 1.5 -12 seconds
in case of a phase loss. This parameter must be set to On during
regular operation.
Phase imbalance (current) trip threshold. Above this value a trip is
generated. This function is activated together with the phase
loss protection.
Phase imbalance (current) warning threshold. Above this value a
warning is generated. This function is activated together with the
phase loss protection.
If enabled the three phases must be fed through the UMC CTs in
the correct order (L1 left, L2 middle, L3 right).
Enables supervision of phase sequence (L1/L2/L3)
Value in % of I/I . Below this value a trip is generated. A value of
e
0% disables the trip.
Value in % of I/I . Below this value a warning is generated. A value
e
of 0% disables the warning.
Delay time until a low current trip is triggered.
Delay time until a low current warning is triggered.
Value in % of I/I . Above this value a trip is generated. A value of
e
800% (160) disables the trip.
Value in % of I/I . Above this value a warning is generated. A value
e
of 800% (160) disables the warning
Delay time until a high current trip is triggered..
Delay time until a high current warning is triggered.
Options
Off (0), On (1)
Note: If the voltage module
is present this parameter
activates both voltage and
current based phase loss
detection.

Note: If the voltage module
is present this parameter must

Warning (2)
Note: If the voltage module
is present this parameter
activates both voltage and
current based phase sequence
protection.
