Extraction chamber fault
This chapter describes the approach to fault analysis and troubleshooting the extraction chamber. The

extraction chamber process with detailed background information on the brief instructions.
9.1.1 Brief instructions on site
Execute the following points in succession:
• NEVER switch the power supply of a faulty device on and off to make it work again!
• Please ensure that the “Activate device” key is active ( ).
• Please ensure that the external slide / ball valve has not been accidentally closed.
• Check the fault status display on the main menu.
• Use the MSENSE® DGA Service Tool to read out the service data.
• Carefully remove the device's protective hood.
• Check the extraction chamber by way of visual inspection.
• Check to see if oil is found in the hood or on the device's components.
• Check if loose pneumatic connections (air white / oil yellow) can be found.
• Check for loose electrical connections.
• If necessary, repair or replace the defective components.
• If there are no faults in the device, open the Extraction Status menu.
• Acknowledge the fault in the extraction status menu using the key.
• Monitor the device while the initialisation cycle is in progress.
• Wait for the next measurement cycle and monitor the process.
• Should a fault occur again in the device, read out the service data once again.
