SSM 6000 GENERAL SAFETY INFORMATION CONT General safety information The following safety information must always be observed during operation as well as during any maintenance and repair work on this device. Non-compliance with safety measures or any other information or warnings contained in this user manual constitutes a violation of safety standards underlying the design, manufacture and proper use of the device.
The analyzer features ease of operation and a clear-cut display structure. In terms of time and frequency of use, the SSM 6000 family can draw on the largest experience of all biogas analyzers available on the market. The first analyzer developed in Europe specifically for continuous operation in biogas plants belongs to the SSM family and has been in use since 1998.
Gas mixtures with critical concentration relationships between methane and oxygen are flammable. Although critical gas mixtures of this kind are very rare in biogas plants, the utmost must be done in order to avoid the risk of ignition. In the SSM 6000, a detonation protection unit separates the analyzer from the biogas plant.
SSM 6000 HARDWARE DESCRIPTION CONT 2 HARDWARE DESCRIPTION Measuring characteristics The SSM 6000 Continuous analyzer was developed for the continuous measurement of CH , CO and for the discontinuous determination of H S and H concentrations in biogenic gases. The table below contains details concerning measuring ranges, etc.

SSM 6000 HARDWARE DESCRIPTION CONT The measuring gas is initially drawn in through the safety device (1) of the selected measuring point (15) and cooled down to 5°C in the measuring-gas cooler (2). The hose pump (3) pumps the resultant condensate to the condensate discharge. The condensate must be collected and disposed of by the equipment user.
SSM 6000 HARDWARE DESCRIPTION CONT 2.2.2 Display and control panel The measured values are displayed for each gas type on the four-digit LED panels in the respective unit (Vol.% and ppm, respectively). In the case of devices with reduced functionality, the displays of gas types not included in the functionality remain inactive.
Measuring-gas filter Several filters are integrated into the gas path of the SSM 6000 in order to protect the sensors and other components of the system. The filters clean the biogas and the ambient air drawn in, thereby increasing both the service life of the sensors and the measuring precision of the system.
2.2.5 Measuring gas cooler (option) The SSM 6000 Classic analyzer version comes with a serial measuring-gas cooler. The SSM6000 LT is available with an optional measuring-gas cooler. Measuring-gas coolers are used in analyzer systems to process contaminated and humid measuring gases and to lower their dew point.
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.
1 must be interrupted during measuring breaks with admission pressures of more than 5 hPa, using suitable means, such as an automatic stop valve. The solenoid valve can be controlled via the "Measurement active" status output of the SSM 6000 on the underside of the analyzer (port 2).
The mains disconnector switch must be marked in a manner that clearly shows the equipment to be disconnected. Signals and interfaces The SSM 6000 analyzer comes with the following connections for communicating with peripheral equipment. Plug connector Description...

Stop valves should be installed at the sampling points of the biogas plant in order to prevent biogas from escaping when the measuring-gas hoses are disconnected. The measuring-gas pipe should, if possible, slope towards the sampling point, so that any condensate produced can flow back into the process.

SSM 6000 SETTING INTO OPERATION CONT Checking the interface functions The analyzer can simulate three analog output values in order to check the analog data output functionality and to adjust this to the higher-level plant control system, if necessary. This enables adjustment of external isolating switching amplifiers or arithmetic correction by the controller.

In order to ensure correct measuring results within the specified tolerances, analyzers and systems must be calibrated at regular intervals. With the SSM 6000, the individual gas types are calibrated using certified calibration gases and/or calibration gas mixtures. Note that incorrect calibration leads to incorrect results during subsequent measurements! Before any service or maintenance intervention, the higher-level system (plant control system) must be notified of any such work in advance in order to avoid emergency shut-down of the motor in response to incorrect measuring values.
CALIBRATION CONT The process of calibrating the SSM 6000 consists of the following steps: Rinsing the gas ducts and pipes with ambient air in order to record the sensor zero points Determining the sensor sensitivity values using biogas / calibration gas Rinsing the system using filtered ambient air.
SSM 6000 CALIBRATION CONT Calibration procedure Calibration of the system can start after you have determined the ACTUAL condition and checked the sensor signals. The calibration menus are accessed after operation of the key switch via the selection level SETUP MODE CALIBRATION PARAMETERS.
SSM 6000 CALIBRATION CONT When the zero points are accepted the request „CONNECT SPAN GAS!” is displayed. CALIBRATION Connect the span gas to the sample inlet for sample point 1 with a maximum pressure of 0.4bar CONNECT SPAN GAS! and confirm the request by pressing the <enter> key.
SSM 6000 CALIBRATION CONT Calibrating the oxygen sensor Besides the normal calibration routine, it is also possible to adjust the sensor sensitivity of the oxygen channel even without test gas because the sensor sensitivity is calibrated using ambient air and because the zero point of the oxygen sensor features long- time stability.
8 Maintenance, repair, customer service The SSM 6000 is a complex electronic measuring device and must hence be handled with care. The manufacturer is solely responsible for the original safety characteristics and features of the device. Any guarantee becomes void if the device is modified in any manner not performed or approved by the manufacturer.

Description PROFIBUS interface Introduction This technical description deals with the Profibus DP (DP Decentralized Periphery) slave interface of the SSM6000. The correct description is as follows: Profibus-DP: Compliance to IEC 61784 Ed.1:2002 CPF 3/1 Electrical transmission equipment Interface properties of the SSM6000 The SSM6000 comes with a galvanically (optically) isolated Profibus interface according to IEC61784 Ed.1:2002 CPF3/2 (formerly EN50170).
Description PROFIBUS interface Bus termination The PROFIBUS interface of the SSM6000 does not terminate the PROFIBUS at the device end. The SSM6000 does not set the open-circuit level of the bus at the device end. If this is required, the necessary measures must be implemented in the PROFIBUS connector.
Description PROFIBUS interface In the parameter data telegram, the following pattern can appear for example 1: Param. DPV1-1 DPV1-2 DPV1-3 Module parameter P1..P7 Configuration data The configuration data is transmitted in the "special format". The following example refers to CH4: 42 , 83 , 00 , 01...
Description PROFIBUS interface Cyclic mode The SSM6000 DP slave features a modular design. The data modules can be combined in any order for cyclic operation. It is not necessary to insert blank modules, and it is possible to select several modules at the same time. The only restriction is that the maximum number of inputs and outputs (as specified in the GSD file) may not be exceeded.
Description PROFIBUS interface The same error message is generated if the "Measurement" data module was selected (parameterized) for cyclic data exchange. Otherwise the output value which is output in acyclic mode would be cyclically overwritten. Write access is possible via index 2 only.
