group 0-4.
Table 4 Warning indication
Status Cause/Possible cause
Current imbalance warning Current imbalance between the phases has exceeded the warning level.
Over voltage warning The RMS phase to phase voltage has exceeded the adjustable value.
Under voltage warning The RMS phase to phase voltage has decreased below the adjustable
value.
EOL time-to-trip warning The predicted time before EOL trip has reached the warning level.
EOL warning The calculated motor temperature has exceeded the warning level.
Total Harmonic Distortion (THD(U)) warning THD(U) has exceeded the warning level. Check the quality of the
network.
Voltage imbalance warning Voltage imbalance between the phases has exceeded the warning level.
Power factor underload warning The power factor has decreased below the adjustable value during
continuous operation.
Current underload warning The motor current has fallen below the warning level.Check that the
motor current parameter (Ie) is set correctly.
Faulty fan warning The fans are not working properly because dust or mechanical blocking
The sofstarter could be overheated.
Check that the fans are working and rotating freely. The blades shall
rotate without any resistance.
CAUTION
The fans may only be checked when in voltage free state.
If the fault remains, contact ABB sales office.
Locked rotor warning The motorcurrent has exceeded the warning level. A damaged bearing or
a stuck load could be possible causes.
Thyristor overload warning The calculated thyristor temperature has exceeded the
warning level.
Short circuit warning There is an internal short circuit and the softstarter is running in limp
mode. See chapter 7 Functions.
