    It should be noted that a lightly loaded motor takes less torque, and thus lower voltage and time to accelerate to full speed. For this case the S611 will go into bypass before the ramp reaches full voltage. In other words, the S611 will go into bypass before the Soft Start Time has elapsed.

  • Page 31: Current Limit

    This mode is typically used when it is necessary to limit the maximum current during start-up due to line power limitations or other considerations. During a current limit start the S611 applies a constant voltage to the motor, resulting in limited current flowing through the motor’s windings.

    The Permissive and Network inputs must be energized (120 Vac) to enable starting of the soft starter from the network. After an overload trip, the S611 soft starter cannot be restarted until the prescribed cool-down time has elapsed. Cycling control power does not reset the timer. If 120 Vac power is removed, the soft starter will remember the remaining time and will resume the cool-down timing when power is again reapplied.

    Note: The User Interface module is not required (default) for operation of the S611 after the parameters have been set. The S611 may be configured to fault if the User Interface module is removed by enabling the User Interface Comm Loss Fault parameter setting in the Advanced Config. menu. To reinstall a UI that has been removed, remove 120 Vac control power, reinstall the UI, then restore 120 Vac control power.
  • Page 90 If the resistance is near zero (less than 5 ohms), it is most likely that the SCR is shorted. Resistance of a serviceable SCR is approximately 10k ohms. Resistance typically moves to a lower value as the SCR ages. This feature may be disabled (not recommended). S611 Soft Starter MN03902011E—May 2012 www.eaton.com www.comoso.com...
  • Page 91 During the start ramp time, the maximum rms value of the three-phase current(s) are monitored. Instantaneous overcurrent trip threshold is 6 X catalog FLA. The trip delay is 1.5 seconds and is not user settable. Catalog FLA refers to the maximum continuous line current capacity of the S611 soft starter, NOT the motor rated FLA.
  • Page 92 • Reduce starting load • Verify S611 is properly rated for current Note: The maximum rms value of the three-phase currents is monitored. The current values observed in the UI display should be within ±5% of each other The SCR overcurrent trip threshold is 3 x FLA at the end of the start ramp time and is not user settable.
  • Page 93 Monitors the maximum rms value of the three-phase current and is not user settable. Catalog FLA refers to the maximum continuous line current capacity of the frame size of the S611, NOT the motor rated FLA. At 4 x FLA, the following approximate trip delay times are; Class 5 = 4.5 seconds, Class 10 = 9.0 seconds, Class 20 = 16.0 seconds, Class 30 = 23.0 seconds.
