Thermal Overload
The S611 soft starter features an electronic motor overload protection feature. It is designed to
protect the motor and power wiring against overheating caused by operating at excessive current
levels for extended periods of time.
Entering the motor’s full load current rating, using the Motor FLA parameter programs the
overload. The Motor FLA is settable from 50% to 100% of the S611’s rated current (frame size).
The overload’s trip class is set using the Trip Class parameter in the Protection menu. Editing the
Trip Class parameter to “OFF” will disable overload protection.
Additional details on the thermal overload can be found in Appendix B—Protection .
Protection
In addition to motor overload protection, the S611 has many programmable features designed to
protect the motor as well as the soft starter itself.
●
Incoming line phase reversal, loss, imbalance, over voltage, and under voltage trips
●
Three overcurrent trip levels
●
Stall and jam trips
For troubleshooting purpose trips are recorded, as they occur, in the S611’s fault log.
Apply the mains voltage and verify that no fault is present. The S611 indicates most faults with a
fault code in the alphanumeric display and by illuminating the corresponding mode and Protection/
Operation (P/O) LEDs. When a fault is indicated, the dedicated Fault P/O LED will be illuminated.
4. The fault history may be displayed by pressing the Fault Log button.
A Phase Reversal fault is a likely candidate on new installations. It can be remedied by either
changing the Phase sequence P/O LED from ABC to ACB or removing mains power and
switching the incoming line connections at L1 and L2 of the S611.
