  • Page 34 OPERATION Kickstart Kickstart provides a short boost of extra torque at the beginning of a start, and can be used in conjunction with current ramp or constant current starting. Kickstart can be useful to help start loads that require high breakaway torque but then accelerate easily (for example helical rotor pumps).

  • Page 35: Stop Methods

    OPERATION been tested on a different motor prior to actual installation, the starter will need to learn the characteristics of the new Motor Full Load Current motor. The EMX3 will automatically re-learn the motor's characteristics if parameter 1A Adaptive Control Gain parameter 2K is changed.
  • Page 36 OPERATION Adaptive Control for Stopping In an adaptive control soft stop, the EMX3 controls the current in order to stop the motor within a specified time and using a selected deceleration profile. Adaptive Control can be useful in extending the stopping time of low inertia loads. Every application has a particular stopping profile, based on characteristics of the load and the motor.
  • Page 37 OPERATION Brake Brake reduces the time required to stop the motor. During braking an increased noise level from the motor may be audible. This is a normal part of motor braking. When brake is selected, the EMX3 uses DC injection to slow the motor. EMX3 braking: Does not require the use of a DC brake contactor •...

  • Page 38: Jog Operation

    OPERATION Jog Operation Jog runs the motor at reduced speed, to allow alignment of the load or to assist servicing. The motor can be jogged in either forward or reverse direction. CAUTION Slow speed running is not intended for continuous operation due to reduced motor cooling. Jog operation causes the motor to heat faster than the rate calculated by the motor thermal model.

  • Page 66: Auxiliary Trip Circuit

    APPLICATION EXAMPLES 11.4 Auxiliary Trip Circuit In normal operation the EMX3 is controlled via a remote two-wire signal (terminals C31, C32). Input A (terminals C53, C54) is connected to an external trip circuit (such as a low pressure alarm switch for a pumping system). When the external circuit activates, the soft starter trips, which stops the motor.

  • Page 67: Dc Brake With External Zero Speed Sensor

    APPLICATION EXAMPLES 11.5 DC Brake with External Zero Speed Sensor For loads which may vary between braking cycles, there are benefits in using an external zero-speed sensor to interface with the EMX3 for brake shut-off. This control method ensures that the EMX3 braking will always shut off when the motor has reached a standstill, thus avoiding unnecessary motor heating.

  • Page 68: Soft Braking

    APPLICATION EXAMPLES 11.6 Soft Braking For applications with high inertia and/or a variable load, the EMX3 can be configured for soft braking. In this application the EMX3 is employed with forward run and braking contactors. When the EMX3 receives a start signal (pushbutton S1), it closes the forward run contactor (K1) and controls the motor according to the programmed primary motor settings.

  • Page 76: General Faults

    TROUBLESHOOTING 12.3 General Faults This table describes situations where the soft starter does not operate as expected but does not trip or give a warning. Symptom Probable Cause Starter "Not Ready" • Check Input A (C53, C54). The starter may be disabled via a programmable input. If parameter 6A or 6F is set to Starter Disable and there is an open circuit on the corresponding input, the EMX3 will not start.
  • Page 77 TROUBLESHOOTING Symptom Probable Cause Motor does not reach full speed. • If the start current is too low, the motor will not produce enough torque to accelerate to full speed. The soft starter may trip on excess start time. NOTE Make sure the motor starting parameters are appropriate for the application and that you are using the intended motor starting profile.

  • Page 94: Busbar Adjustment Procedure

    BUSBAR ADJUSTMENT PROCEDURE 14. Busbar Adjustment Procedure The busbars on non-bypassed models EMX3-0360C ~ EMX3-1600C can be adjusted for top or bottom input and output as required. NOTE Many electronic components are sensitive to static electricity. Voltages so low that they cannot be felt, seen or heard, can reduce the life, affect performance, or completely destroy sensitive electronic components.
  • Page 95 BUSBAR ADJUSTMENT PROCEDURE NOTE If moving the input busbars, the current transformers (CTs) must also be reconfigured. Label the CTs L1, L2 and L3 (L1 is leftmost when looking from the front of the starter). Remove the cable ties and unscrew the CTs from the bracket.
