Gas connections / safety features

All gas connections are located on the underside of the analyzer. The connections are clearly marked and may not be exchanged.
The gas-carrying pipes are connected to the device by means of clamping-ring screw connections.
The following connections must be made:
* Up to four measuring points with an automatic switching function are optionally available (refer to section 2.2.8).
The delivery includes 20 meters of PVC hose (an additional 10m per measuring point with the measuring-point switch option) and
the required connections.
In order to protect the biogas plant against flashback, a safety unit is installed at the measuring-gas input of the analyzer which
prevents flashback into the gas-carrying system of the plant in the case of pipe leakage.
The device is at present fitted with the F 510 detonation protection system according t EN 12874 / PTB 02 ATEX 4012X made of
stainless steel. The manufacturer's conformity declarations and test certificates for the safety and protection equipment are shown in
the appendix to this manual.
2.2.8

Measuring-point switch (option)

Depending on equipment enables the implementation of up to four measuring-gas inlets with detonation protection and 3/2-way
solenoid valves for switching between the measuring points.
The solenoid valves are controlled and the measuring points selected by the SSM 6000. A measuring process can be triggered
manually via the digital inputs at port 1 or the (optional) Profibus interface.
With the device in "MANUAL" mode, a measuring process can be started in stand-by mode at any time by pressing the <enter> key.
You are first prompted to select the measuring point via the <up> and <down> keys. Thereafter, press the <enter> key once again in
order to confirm the start of the measuring process.
The Analyzer comes with four digital inputs at Port 1 which are used to start the H
select the measuring point. The digital optocoupler inputs are assigned as follows and must be activated for around 1.5 seconds:
DI 01 - measuring point 1
DI 02 - measuring point 2 / valve 1
DI 03 - measuring point 3 / valve 2
DI 04 - measuring point 4 / valve 3
After the start of the measuring process, the analyzer simultaneously activates the corresponding measuring-point valve and/or the
pertinent digital output at plug connector PORT2. The digital inputs are not read again until a H
completed. After an H S measuring cycle, the continuous measuring mode of the other components continues to be active until
2
another measuring point is selected or until the <esc> key is pressed in order to terminate the measuring cycle.
If the device is controlled via the digital inputs or via the Profibus interface, an H
