Cause/Possible cause
Current imbalance between the phases is higher than the warning level.
The motor current is below the warning level. Make sure that the motor
current parameter (Ie) is set correctly.
The calculated motor temperature is higher than the warning level.
The motor current is higher than the warning level. A damaged bearing or
a stuck load can be possible causes.
The RMS phase to phase voltage is higher than the adjustable value.
The RMS phase to phase voltage decreased below the adjustable value.
The power factor decreased below the adjustable value during
continuous operation.
THD(U) is higher than the warning level. Do a check of the quality of the
network.
The calculated thyristor temperature is higher than the warning level
Voltage imbalance between the phases is higher than the warning level.
There is an internal short circuit and the Softstarter runs in limp mode.
See chapter 7 Functions.
The predicted time before EOL trip is at the warning level.
Voltage to one or more phases missing. Check that the mains are
connected and that no line contactor or breaker is open.
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
Reset operating data and select Number of starts (resettable) to perform
the reset.
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
Reset operating data and select Motor run time (resettable) to perform
the reset.
The built-in Modbus RTU slave is enabled but the Com 3 function is not
set to Modbus RTU
