What does 'Transmitter 1 Warming up ! Transmitter 1 Error !' mean on Dräger Gas Detectors?
- B
  Barbara FoleyAug 17, 2025
  The message 'Transmitter 1 Warming up ! Transmitter 1 Error !' on Dräger Gas Detectors indicates that the transmitter is either warming up or there is an electronic fault. If the issue is due to the transmitter warming up, the fault will resolve itself at the end of the warming-up time. However, if the problem persists, the transmitter may need to be replaced, or you may need to contact DrägerService.

Why Dräger Gas Detectors VarioGard says 'Voltage is too low'?
- L
  Laura McmillanSep 5, 2025
  The 'Voltage is too low !' error on your Dräger VarioGard Gas Detectors can occur due to several reasons: * If using a 28 V DC mains supply, the voltage may be too low; check the 28 V DC mains. * If using 110 V mains, the power supply might be set to 230 V; convert the power supply to 110 V. * In case of an electronic fault, contact DrägerService.

Why is my Dräger VarioGard Control Unit showing a voltage too low error?
- U
  uhessSep 8, 2025
  If your Dräger VarioGard control unit displays a 'Voltage too low' error, there are several potential causes. If you're using DC mains, the voltage may be insufficient, so check the DC mains. Alternatively, if you're using 115 V mains, the power supply might be incorrectly set to 230 V; in this case, convert the power supply to 115 V. If neither of these resolves the issue, it could be an electronic fault, which requires repair by Dräger Service.
