    ABOUT THIS MANUAL 1. About This Manual WARNING Indicates a hazard that may cause personal injury or death. CAUTION Indicates a hazard that may damage the equipment or installation. NOTE Provides helpful information. 1.1 Disclaimer The examples and diagrams in this manual are included solely for illustrative purposes.

  • Page 5: Caution Statements

    CAUTION STATEMENTS 2. Caution Statements Caution Statements cannot cover every potential cause of equipment damage but can highlight common causes of damage. It is the installer's responsibility to read and understand all instructions in this manual prior to installing, operating or maintaining the equipment, to follow good electrical practice including applying appropriate personal protective equipment and to seek advice before operating this equipment in a manner other than as described in this manual.

  • Page 6: Unexpected Operation

    CAUTION STATEMENTS 2.2 Unexpected Operation WARNING – ACCIDENTAL STARTS In some installations, accidental starts may pose an increased risk to safety of personnel or damage to the machines being driven. In such cases, it is recommended that the power supply to the soft starter is fitted with an isolating switch and a circuit-breaking device (eg power contactor) controllable through an external safety system (eg emergency stop, fault detector).

  • Page 48: 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 49 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 50: Stop Methods

    OPERATION 100% 1. Constant Acceleration 2. Start Ramp Time (parameter 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 51 OPERATION 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.

    APPLICATION EXAMPLES 10. Application Examples 10.1 Smart Card - Pump Protection The EMX4e smart card is ideal for applications with extensive external inputs, such as pumping situations where external sensors provide additional protection to the pump and motor. In this example, the soft starter controls a bore pump. The pump is manually started and stopped using the digital control inputs.

  • Page 85 APPLICATION EXAMPLES 10.2 Smart Card - Level Controlled Pump Activation The EMX4e smart card can be used to control start/stop activation of the starter, based on information from external inputs. In this example, the EMX4e controls a pump which fills a tank, with maximum and minimum water levels.
  • Page 86 TROUBLESHOOTING 11. Troubleshooting 11.1 Protection Responses When a protection condition is detected, the EMX4e will write this to the event log and may also trip or issue a warning. The soft starter's response depends on the Protection Action setting (parameter group 6). Some protection responses cannot be adjusted by the user.
