    SAFETY, WARNING & CAUTIONS A WARNING identifies conditions or procedures that can be dangerous to the user. A CAUTION identifies conditions or procedures that can cause damage to the Product. WARNING Make sure no hazardous gas is present in the area before and during installation. Violation of the National Electrical Code requirements (especially Article 500 that deals with hazardous areas) may cause a fire or explosion with the potential for serious injury or loss of life.
  • Page 10 WARNING The following power requirements must be met by the installer of the DC/AC power connections to the Analyzer: – You must include an electrical disconnect means and a current limiting device, such as a switch and fuse. The disconnect device must be marked as a ‘disconnect device’ and readily accessible to shut off power to the Analyzer.
  • Page 11 – Any AC voltages outside this range may cause the Analyzer to malfunction Any use of this equipment in a manner not specified in this manual or approved AMI documentation may impair the protection provided by the equipment. Toute utilisation de cet équipement d’une manière non spécifiée dans ce manuel ou dans la documen tation AMI approuvée peut altérer la protection fournie par l’équipement.

  • Page 19: Gas Connections

    Sample Gas Inlet Pressure to the Analyzer should be regulated down to the range of 1.0 to 20.0 psig (0.07–1.4 bar), depending on the line pressure – The BARRACUDA MODEL 4010LX comes internally equipped with a complete Sample System, including a Liquid Separator that effectively removes liquids and particulates –...
  • Page 20 Steps The BARRACUDA MODEL 4010LX has three (3) gas connections on its right side. Exhaust Port Sample Gas Inlet Port Bypass Gas/Liquid Drain Sample Gas Connection 1. Take a deburred length of 1/4” stainless–steel tubing and slip it through the supplied compression nut and ferrule set.
  • Page 21: Initiation Of Sample Flow To The Analyzer

    CAUTION The EXHAUST LINE must run slightly downhill the entire way to a safe area to allow any condensate to drain outside and not back into the Analyzer. If you must run the EXHAUST LINE vertically through the ceiling, install a ‘knock-out’ pot to capture the liquid condensate just prior to going vertical.
  • Page 22 Then, remove the flow meter and reattach the bypass tubing. NOTE: AMI has chosen this technique since all bypass flow meters have a tendency to plug quickly due to the volume of liquids and particulates going through the bypass path.
  • Page 23: Calibration

    CALIBRATION Unlike most gas sensing technologies, MODEL 4010LX moisture analyzer does not require periodic calibrations. By design, there is no required method for field-calibrating a 4010LX. Wavelength tunable diode laser (WMTDL) spectroscopy-based instruments, like the 4010LX, are extremely stable and reliable. END OF CALIBRATION Click here return to a Table of Content page.

  • Page 32 8. Disconnect the multimeter from the system leaving the wiring attached to the analog output. Verify the reading in your attached device and if additional tuning is required continue calibrating any offset. This procedure is detailed in previous step SYNC YOUR EFM.
  • Page 33 B. Set the ALARM DELAYS. There are two (2) ALARM DELAYS. Each ALARM DELAY setting is located beneath the corresponding ALARM that it controls. Enter your desired time duration for each ALARM DELAY and press the ENTER key on your laptop. You can also adjust using the UP AND DOWN ARROWS.
  • Page 34 View the ALARM STATUS. Both independent ALARMS have their own ALARM STATUS. If an ALARM is not triggered, the ALARM STATUS will display ‘OFF’ in green. If an ALARM is triggered, its ALARM STATUS will display ‘ON’ in red. *For an ALARM to be triggered, it will take into account the complete logic of how the ALARM was set up.
  • Page 35 C. Click on the drop-down menu and set the Alarms to FAILSAFE or NON FAILSAFE. – If set to FAILSAFE, the ALARMS will trigger if the power supplied to the Analyzer drops below 8.5V. However, the ALARMS will not clear until the power moves back up and exceeds 12V.
