    OPERATION CAUTION Continued use of emergency mode is not recommended. Emergency mode may compromise the starter and/or motor life as all protections and trips are disabled. Using the starter in emergency mode will void the product warranty. 8.4 Auxiliary Trip An external trip circuit (such as a low pressure alarm switch for a pumping system) can be used to trip the soft starter and stop the motor.

  • Page 50: Soft Start Methods

    OPERATION 8.6 Soft Start Methods Constant Current Constant current is the traditional form of soft starting, which raises the current from zero to a specified level and keeps the current stable at that level until the motor has accelerated. Constant current starting is ideal for applications where the start current must be kept below a particular level.
  • Page 51 OPERATION Timed Voltage Ramp Timed voltage ramp (TVR) soft starting ramps the application of voltage to the motor over a defined time period. The voltage ramp reduces the initial starting torque and slows the motor's rate of acceleration. TVR starting can be useful for applications where multiple motors of different sizes are connected in parallel, and/or the loads are not mechanically linked.

  • Page 52: Stop Methods

    OPERATION 100% 1. Constant Acceleration Start Ramp Time (parameter 2B) Time • Fine-tuning Adaptive Control If the motor does not start or stop smoothly, adjust the adaptive control gain (parameter 2I). The gain setting determines how much the EMX4e will adjust future adaptive control starts and stops, based on information from the previous start.
  • Page 53 OPERATION Stop Time (parameter 2G) Time Adaptive Control for Stopping In an adaptive control soft stop, the EMX4e controls the current in order to stop the motor within a specified time. Adaptive Control can be useful in extending the stopping time of low inertia loads. If adaptive control is selected, the first soft stop will use timed voltage ramp.

  • Page 84 TROUBLESHOOTING Display Possible cause/Suggested solution This trip is not adjustable. L1 phase loss During pre-start checks the starter has detected a phase loss as L2 phase loss L3 phase loss indicated. In run state, the starter has detected that the current on the affected phase has dropped below 10% of the programmed motor FLC for more than 1 second, indicating that either the incoming phase or connection to the motor has been lost.
  • Page 85 TROUBLESHOOTING Display Possible cause/Suggested solution This trip is not adjustable. Motor connection • Ensure the motor is connected to terminals T1, T2, T3 using in-line (three wire) connection. The EMX4e does not support inside delta (six wire) connection. • If the soft starter is connected to a grounded delta mains supply, the starter may incorrectly detect the motor Motor Connection configuration.
  • Page 86 TROUBLESHOOTING Display Possible cause/Suggested solution The motor thermistor input has been enabled and: Motor thermistor • The resistance at the thermistor input has exceeded 3.6 kΩ for more than one second. • The motor winding has overheated. Identify the cause of the overheating and allow the motor to cool before restarting.
