4.1 Preparation
4.1.1 Check
 Check with a leak detector:
Are the external hydrogen supply and the hydrogen connection gas-tight?
After a longer period of standstill (several weeks), also check:
 Instrument air supply and fuel gas supply available and clean?
 Gas pressures.
 Sample gas outlet free from any blockages?
 Sampling probe ready for operation?
4.1.2 Procedure
1 Start the peripheral devices (e.g. heated line, sampling probe, catalyst).
If necessary, wait until they are ready for operation (e.g. warming up time).
2 Check the availability of the operating gases (quality, pressure, stock).
3 Switch on the operating gases.
4.2 Start up the FIDOR
1 The FIDOR starts when the power supply is switched on.
2 The green “POWER“ LED on the display of the FIDOR signals that supply voltage is pres-
ent.
– If the green LED does not light:
– Is the mains switch on the rear of the FIDOR switched on?
– Check firm seating of the power plug on the rear of the FIDOR.
– Check the fuse in the mains switch (
