Installation and Connection

Subject to change without notice

3.4.1 Connecting the instrument air



Connect the instrument air supply to the FIDOR.

3.4.2 Connecting the combustion air



Connect the combustion air if an external combustion air supply is used

3.4.3 Connecting the fuel gas (hydrogen)

● Recommendation:

– Fit a pressure monitor on the fuel gas cylinder which monitors the cylinder pressure

and emits a signal at a certain residual pressure (e.g. 10 bar).

– If the FIDOR is integrated in an enclosed system cabinet:

Install an H

flow limiter for the fuel gas supply in the system cabinet and, if

required, install a hydrogen sensor (H

Sensor) (< 25% LEL).



Lay the lines.

– Only use analytically pure tubes made of copper or stainless steel.

– Do not contaminate the insides of tubes during assembly



Connect the fuel gas to the “Fuel gas” connection.

3.4.4 Connecting the test gases

3.4.4.1 Zero gas



Connect the zero gas.

3.4.4.2 Reference gas

Recommendation:

Monitor the feed pressure of the reference gas with a pressure monitor which emits an

electric signal at a certain minimum pressure (e.g. 10 bar).

Connect the signal of the pressure monitor with the “External signal failure” control input.



Connect the reference gas.

WARNING: Risk of explosions

The screw fitting for the fuel gas supply contains a flow limiter.

● The fuel gas inlet is marked “Fuel Gas”.



Do not modify this screw fitting.



Do not connect the fuel gas supply to any other screw fitting.
