What to do if temperature in LEYBOLD TURBOVAC is too high?
- K
  Kelly LeeJul 31, 2025
  If the temperature in the LEYBOLD TURBOVAC is too high or the coding is wrong, several factors could be the cause. It could be due to frequent switching between acceleration and braking, in which case you should let the pump cool down and operate it under normal load only. Alternatively, there might be poor cooling or an interruption in the cooling line, so you should check the cooling system. Finally, excessive current in the output stage of the TURBOTRONIK, such as a short-circuit, could be the issue. In this case, turn off the POWER switch on the TURBOTRONIK, fix the fault, and then switch it back on.

  If the temperature in the LEYBOLD TURBOTRONIK is too high, it could be due to frequent switching between acceleration and braking, or because the ambient temperature is too high. To resolve this, allow the TURBOTRONIK to cool down, ensure it has adequate ventilation, and only operate the pump under a normal load.

What to do if LEYBOLD TURBOVAC has not attained the target speed?
- D
  Dale HarperAug 8, 2025
  If the LEYBOLD TURBOVAC has not reached the target speed within 10 minutes, it could be due to forevacuum pressure being greater than 10-2 mbar. Check the forevacuum. Another possible reason is that the pump is blocked. In this case, check the vacuum chamber.
