  • Page 15: Safety

    Programming Guide | VLT® HVAC Drive FC 102 Safety Safety Safety Symbols The following symbols are used in Danfoss documentation. DANGER Indicates a hazardous situation which, if not avoided, will result in death or serious injury. WARNING Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
  • Page 16 Programming Guide | VLT® HVAC Drive FC 102 Safety WARNING UNINTENDED START When the drive is connected to AC mains, DC supply, or load sharing, the motor may start at any time. Unintended start during programming, service, or repair work can result in death, serious injury, or property damage. Start the motor with an external switch, a fieldbus command, an input reference signal from the local control panel (LCP), via remote operation using MCT 10 software, or after a cleared fault condition.

  • Page 17: Protection Mode

    Programming Guide | VLT® HVAC Drive FC 102 Safety Protection Mode Once a hardware limit on motor current or DC-link voltage is exceeded, the drive enters protection mode. Protection mode means a change of the PWM modulation strategy and a low switching frequency to minimize losses. This continues for 10 s after the last fault and increases the reliability and robustness of the drive while re-establishing full control of the motor.
