4.3.4
Setting the operating pressures
Set the combustion air and the combustion gas pressure
Gas
Input pressure
Combustion gas (hydrogen)
2000 – 4000 hPa rel.
Combustion air (synth. air)
2000 – 4000 hPa rel.
1.
Set the pressures of the gases connected outside the unit (combustion air and
combustion gas) to a value between 2000 and 4000 hPa.
2.
Connect the gases to the provided gas connections on the rear of the unit.
3.
Start the unit (switch on the power supply). The unit is now in the warm-up phase and
checks here that the supply gases are connected.
4.
Wait about 30 to 45 minutes before taking any further action.
5.
Now select function 2 "Diagnostic values" and read off the pressures for combustion air
and (hydrogen) combustion gas. The pressure for the combustion air must be 480 hPa
+0/-5 hPa. The pressure for the combustion gas must be 1000 hPa ±5 hPa.
6.
If these values aren't what they should be, readjust them. To do this, open the front panel
and adjust the pressures using the pressure regulators behind this.
7.
Now wait until the flame of the flame ionization detector (FID) is burning. As soon as it
burns, the FIDAMAT 6_G switches to the "standby" operating state, which can be seen in
the bottom line of the measured value display. You can return to the measured value
display by pressing the [MEAS] or [ESC] key.
