Neverthe- less, hazards may occur during its use which can be avoided by observing these instructions. You may only use the RGQ 5 Gas Quality Analyzer for its intended purpose and if it is in perfect technical condition.
However, this note can also give you tips on how to make your work eas- ier. In addition, this note provides you with further information on the de- vice or the work process, which can be used to avoid incorrect behavior. Manual RGQ 5 EN00 07.12.2020...
Note All instructions in the manual must be observed. The RGQ 5 gas quality meter may only be used in accordance with the op- erating instructions. RMG accepts no liability for damage caused by non-observance of the op- erating instructions.

1.1.5 Risk assessment and minimization The RGQ 5 Gas Quality Meter is subject to risks in its use, which have been as- sessed by qualified personnel. Risks may arise, for example, from use outside the permissible temperature range. Impermissible current and voltage values can trig- ger explosions in the potentially explosive area.
Observe the specifications of the system manufacturer or system operator. 1.1.6.2 Dangers for operation in EX areas Variants of the RGQ 5 Gas Quality Meter are intended for use in potentially explo- sive atmospheres. If you make technical changes to the device, safe operation can no longer be guaranteed.
Manual … … Note The list below applies to the RGQ 5 stand-alone (loose, not installed on the back plate). The variants installed on a mounting plate have an integrated fine pres- sure reduction, bypass and SBV. Optionally, the mounting plate with all accessories can be installed in a protective box.
Avoid long storage times. Check the RGQ 5 Gas Quality Meter for damage and function after storage. Have the device checked by RMG Service after a storage period of more than one year. To do this, send the device to RMG or make an ap- pointment with the RMG service organization.
It also contains specifi- cations for the transport and storage of the RGQ 5 gas quality meter. The second part describes the structure of the RGQ 5 gas quality meter. The third part de- scribes the operation of the RGQ 5 and its intended use.

1 About this manual 1.4 Certification for hazardous area The gas analyzer RGQ 5 is certified for use in Ex zone 1. If you have any ques- tions, please contact RMG for additional information. Danger When installing in hazardous areas, ensure that the housing potential is balanced.
Interventions or modifications to the gas analyzer that are not described in these operating instructions are not permitted. Make sure that attachment points are burr-free and clean. After installation, use a gas sensitive gas leak detector to ensure there is no leak. Manual RGQ 5 EN00 07.12.2020...

(e.g. IEC 60079-20). Note Regular maintenance of the device is not required under normal use. For further information, please contact RMG. Have repairs carried out only by RMG to avoid loss of warranty claims. Note The device is calibrated at the factory. For recalibration or retrofitting, please contact RMG.
1100 mbar absolute Figure 1: Connection of the RGQ 5 to the gas line Danger Make sure that the device to be installed is calibrated for the gas present in the system. Failure to do so may result in possible damage due to in- correct control values and may also result in hazardous situations may arise.

2 Installation Flow direction and outlet The RGQ 5 has a predefined flow direction. The device inlet can be connected di- rectly to the gas line or tank with built-in pressure reducer. Connection condition The following conditions are required: • Dry, filtered gas (with an external particle filter, pore size 10 µm) •...

To use the current loop correctly, it must be supplied with 24 VDC as shown in the following figure. Figure 2: Current loop connection 2.1.4 RS485 Modbus-RTU connection The RGQ 5 is designed for both full-duplex (4-wire) and half-duplex (2-wire) RS485 Modbus. Danger When installing in hazardous areas, make sure that the housing potential is balanced.
3 Operation The RGQ 5 has no external or internal switches. By connecting wire 1 to +24 VDC and wire 2 to -24 VDC (as described in the table under section 2.9 "Electrical con- nection"), the RGQ 5 automatically starts operation. After approximately 3 minutes, data communication via RS485 Modbus RTU is activated and the 4-20 mA current loop provides a signal.
Communication: with the Modbus USB Windows Interface Package Communication via RMG's Modbus USB Windows interface package allows the user to operate the RGQ 5 in a plug-and-play manner. It has additional features such as creating graphs, saving output parameters in CSV format and switching reference conditions and units, applying moving averages, etc.
Figure 9: RGQ 5 Modbus USB Windows interface package 3.2 First use To reduce the warm-up time during initial operation when the RGQ 5 is connected to a gas supply for the first time, it is recommended to use the "Boosting" function.
°F 3.4 Calibration 4-20 mA current loop The RGQ 5 is shipped from the factory with a calibrated 4-20 mA current loop. Since the actual mA output is affected by the (custom) current loop system, it is strongly recommended to recalibrate the current loop after connecting it to your specific current loop system.
There is no particular reason for the metering reference conditions to be the same as the combustion reference conditions. In RGQ 5, the following reference conditions can be selected: 25/0°C, 0/0°C, 15/0°C, 15/15°C, 20/20°C, 25/20°C at 101325 Pa and 60°F at 14.65 psi, 14.696 psi, 14.73 psi, and 15.025 psi absolute.

Figure 4: Reference conditions according to ISO 6976 Note The RGQ 5 provides the combustion characteristics in all commonly used measurement and reference conditions. Please ensure that the correct ref- erence conditions are selected to avoid any resulting offset between the RGQ 5 output and the comparison values (with other reference condi- tions).
4 Maintenance & regular checks 4 Maintenance & regular checks The RGQ 5 has no moving parts, does not burn the medium flowing through it, and does not react chemically with the medium. As a result, there are minimal maintenance requirements during normal operation. The quality of the medium flowing through is not controlled.

Components must be used that can withstand the maximum expected pressure levels and peaks. Observe working conditions according to data sheet RGQ 5. Interventions or modifications to the gas quality measuring device that are not described in these operating instructions are not per- mitted.
Danger Immediately take a damaged or unsafe instrument out of service and mark it to prevent accidental use. Have repairs carried out only by RMG or rep- resentatives authorized by RMG. Note Please check in advance whether the correct pressure is applied (valves/ball valves etc.
Observe the permissible ambient and media temperatures valid for this range based on the specified temperature classes. The maximum permissible tempera- ture range is specified on the nameplate of the RGQ 5. Operation of the device is only permitted within these specified ranges.
5.4 Measured media Dry, neutral gas (filtered 10 µm) The RGQ 5 can measure gas compositions in a wide range, in the form of H-gas or L-gas, as well as biogas or other (natural and synthetic) gas compositions. However, to ensure accuracy and warranty period, the gas composition range...
