• Frequency range protection
• Phase reversal protection
• Too long start time protection
• Auto restart protection
3.1.2.1
User defined protection
You can use your own specified protection, with the
programmable digital input and an external device/sensor.
The protection operates when the input signal comes at
high level (fieldbus or physical I/O).
3.1.3 Warning
functions
The Softstarter has warning functions for potential risks,
that operate before a protection function operates.
A warning cannot stop the Softstarter. A reset of a
warning is not necessary.
You can change the warning level and other parameters
for the warning functions. Warnings are stored in the
event list.
Available warnings are listed below:
• Current imbalance warning
• Overvoltage
warning
• Under voltage warning
• EOL time-to-trip warning
• EOL
warning
• Total Harmonic Distortion (THD) warning
• Voltage imbalance warning
• Power factor underload warning
• Current underload warning
• Locked rotor warning
• Thyristor overload warning
• Short circuit warning
• Number of starts warning
• Modbus configuration warning
• Phase loss warning
• Motor runtime warning
3.1.4
Fault detection functions
The Softstarter has a number of fault detection functions
to signal malfunction at Softstarter, motor or power
network level. The Softstarter identifies external and
internal faults. The user cannot disable fault detection
functions except for Emergency mode, chapter 7.20.1.
Available faults are listed below:
• Phase loss fault
• High current fault
• Low supply voltage fault
• Bad network fault
• Thyristor overload fault
• Short circuit fault
• Shunt
fault
• Unspecified
fault
• Heatsink overtemperarure fault
• Open circuit thyristor fault
• Faulty
