Testing the electrical supply
1.
Check the device and the surrounding area (gas connections and pipelines) with a
methane detector. If you discover any leaks, close the gas supply, identify the leaks and
seal them. If this is not possible, notify the TAC.
2.
Check the device for signs of damage and loose parts. Notify the TAC if you identify any
damage. Tighten any loose parts. Activate any existing loosening guards, for example on
the hood.
3.
Check the vent line/breather valve. Ensure there is no dirt or blockage. If there is, clean it
or notify your TAC.
Do not use liquids.
4.
Check the fluid connections and electrical cables to ensure they are undamaged. If they
are damaged, replace any damaged components. If this is not possible or spare parts are
required or the housing must be opened, please notify the TAC.
5.
Ensure all unused openings are sealed.
If this is not possible or spare parts are required,
please notify your TAC.
6.
Read the cylinder pressure of the calibration gas and carrier gas on the pressure gauges.
Note: you can empty the cylinder up to a minimum pressure of 1 MPa, but the cylinder
must then be replaced, regardless of the maintenance interval. Replace the auxiliary gas
cylinders if necessary.
7.
Check the inlet pressures
8.
Optional: check the flow rates. If you have flow meters available, compare the current
values with the values obtained during commissioning. If they are different, readjust the
flow rates. If this is not possible with the current inlet pressure, the inlet filters may have to
be replaced. In this case, please contact your TAC.
9.
Create a report on the completion of the work and the results of items 1 – 8 to document
your work and results
8.2.1 Visual inspection of the connections

Action: Visual connection inspection
1.
Check the connections (fluid and electrical) and stainless steel pipelines or
cables to determine whether they are undamaged, complete and free of
corrosion.
2.
If you find any damaged or corroded parts or notice that components are
missing, immediately disconnect the gas and voltage supply.
3.
Replace damaged and/or corroded parts and add missing components so that
all the unused openings are sealed. If you require any spare parts, you can simply
order them at your TAC.
4.
Do not carry out any measurements or work using the
device before the repair work has been completed.
