10.6 Warning indication shown on screen
For a description of the warnings, see chapter 7.18 Warnings.
Table 4 Warning indication
Status Cause/Possible cause
Current imbalance Current imbalance between the phases is higher than the warning level.
Current underload The motor current is below the warning level. Make sure that the motor
current parameter (Ie) is set correctly.
EOL warning The calculated motor temperature is higher than the warning level.
Locked rotor The motor current is higher than the warning level. A damaged bearing or
a stuck load can be possible causes.
Overvoltage The RMS phase to phase voltage is higher than the adjustable value.
Under voltage The RMS phase to phase voltage decreased below the adjustable value.
Power factor underload The power factor decreased below the adjustable value during
continuous operation.
THD(U) THD(U) is higher than the warning level. Do a check of the quality of the
network.
Thyristor overload The calculated thyristor temperature is higher than the warning level
Voltage imbalance Voltage imbalance between the phases is higher than the warning level.
Short circuit There is an internal short circuit and the Softstarter runs in limp mode.
See chapter 7 Functions.
EOL time-to-trip The predicted time before EOL trip is at the warning level.
Phase loss Voltage to one or more phases missing. Check that the mains are
connected and that no line contactor or breaker is open.
Number of starts limit The number of starts exceeds the warning level. Time for service!.
The warning will stay active until the Number of starts (resettable) value
have been reset. Use menu: Menu ĺ Settings ĺ Reset to defaults ĺ
Reset operating data and select Number of starts (resettable) to perform
the reset.
Motor run time limit The Motor runtime exceeds warning level. Time for service!
The warning will stay active until the Motor run time (resettable) value
have been reset. Use menu: Menu ĺ Settings ĺ Reset to defaults ĺ
Reset operating data and select Motor run time (resettable) to perform
the reset.
Modbus configuration The built-in Modbus RTU slave is enabled but the Com 3 function is not
set to Modbus RTU
