  • Page 19: Commissioning

    Commissioning 4 Commissioning 4.1 Installation and Set-up Pre-checks After completing the installation and before starting the system for the first time, please check the following: Check and confirm that all electrical connections are carried out according to the manuals and the technical drawings. Check that the air supply is connected to the air supply filter regulator without leaking and in accordance with good installation practice.

  • Page 20: System Operation

    G4130 NO Analyzing System 5 System Operation 5.1 Calibration Mode In the calibration mode (both Zero and Span), the selector valve must stay at the Calibration position. For zero calibration Turn the selector valve to Zero position. Check that the instrument air (zero NO gas) is connected to the air supply filter regulator.

  • Page 21: Measurement Mode

    System Operation 5.2 Measurement Mode In the measurement mode, both selector valves must point to the Operation posi- tion. The instrument air for back-flushing is regulated by the solenoid valve which is controlled by the analyzer. For back-flushing, the solenoid valve will be opened automatically to allow the probe back-flushing with high air flow.

  • Page 22: Routine Maintenance

    G4130 NO Analyzing System 6 Routine Maintenance 6.1 Calibration The system must be calibrated regularly and always after each start-up of the analyzer. The frequency of calibration depends on each specific application, but we recommend the calibration before making any measuring report or at least once a month.

  • Page 23: Sensor

    Routine Maintenance 6.3 Sensor Warning The analyzer must be turned off and the air supply must be disconnect- ed before you start changing the sensor. If you remove the sensor while there is exhaust gas in the stack, there is a risk that hot exhaust gas will come out of the sensor house.

  • Page 24: Diffusion Probe

    G4130 NO Analyzing System 6.4 Diffusion Probe The probe filter element is normally cleaned by back-flushing. The period be- tween back-flushings depends on the actual flue gas condition and how dirty the filter gets. Regular back-flushing will normally keep the filter clean. However, a slow re- sponse to NO changes in the flue gases indicates that the probe filter may be contaminated.
  • Page 25 Routine Maintenance To clean the probe filter, please go through the following steps: Turn off the analyzer and disconnect the air supply. Unscrew the nuts and remove the blue cover plate of the probe. Unbolt the 3 bolts at the sensor and filter flange. Take the sensor and filter flange out and unscrew the threaded filter Clean or change the filter.
