3.3 Start-up of the TURBOVAC
Press the START key.
The STATUS LED flashes during acceleration. The LED chain indicates the
increasing speed with one LED each. When 80% of the target speed has
been reached, the LED STATUS remains on continuously.
During normal operation the row of LEDs will indicate the amount of power
taken up by the TURBOVAC.
3.4 Operation
During NORMAL operation, the LED STATUS lights and the LED chain
shows, starting at the bottom and moving upwards, the current consumed.
If the target speed of the TURBOVAC cannot be maintained during normal
operation due to overloading (pressure, excessive TURBOVAC or Turbo.Drive
TD20
classic
temperature), the LED ERROR flashes.
The mode is not a failure, but can result in a shut down depending on the
cause of overload, e.g. if the temperature continues to rise.
