    Unauthorised tampering with the unit will void the product warranty. Protection Responses When a protection condition is detected, the Digistart D3 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 16).
  • Page 92 Check for other equipment in the area that could be affecting the mains supply, particularly variable speed drives and switch mode power supplies (SMPS). If the Digistart D3 is connected to a generator set supply, the generator may be too small or could have a speed regulation problem.
  • Page 93 PowerThrough will not operate if control power is cycled between starts. Related Pr: 15D The Digistart D3 has detected a drop in the internal control voltage. Low Control Volts Check the external control supply (CSH, CSL, CSR) and reset the starter.
  • Page 94 A short circuit has occurred. Check and resolve this condition. • Related Pr: None The Digistart D3 is internally bypassed and has drawn high current during running. (The 10A Time-overcurrent protection curve trip has been reached or the motor current has risen to 600% of the motor FLC setting.)

  • Page 95: General Faults

    The starter may be disabled via a programmable input. If Pr 3A or 3F is • set to Starter Disable and there is an open circuit on the corresponding input, the Digistart D3 will not start. If there is no further need to disable the starter, close the circuit on the input. NOTE Pr 3M Local/Remote controls when the LCL/RMT button is enabled.

    DI4, +24V will open and the starter will be disabled. When the next start command is given (ie next application of K10), DI4, +24V closes and the Digistart D3 is enabled. The Digistart D3 must be operated in remote mode and Pr 3A Input A Function must be set to 'Starter Disable'. CAUTION If the brake torque is set too high, the motor will stop before the end of the brake time and the motor will suffer unnecessary heating which could result in damage.
