  • Page 14: Cautions & Installation

    6.Cautions & Installation 6.1 Detector cautions The LD8000 Multigas uses a detection technique known in the industry for many years. The principle is not new, but the design of the detector and the electronics make it unique for its performance and reliability. The analysis is based on spectroscopic emission.

  • Page 15: Installation

    6.3 Installation Some simple steps are required to make a successful installation. Unpack the instrument from the box carefully without damaging the gas connections. Inspect the instrument to be sure it is in good condition and hasn’t been damaged during shipping. Remove all plugs from the gas connections on the rear panel.

    10.2 Software Update Procedure 1) You need to connect a computer to the analyzer with a FTP client. To do that uses a FTP client like Core FTP. (download on www.coreftp.com) 2) Connect an Ethernet cable to your analyzer on your server. You can retrieve the analyzer IP in the configuration menu.
  • Page 52 4) When you are connected to the analyzer (the screen below will then appears), 5) You now have to upload the image.bin to the analyzer: First select the new file ‘’image.bin’’ then click on upload button. It is important to not modify the other files .ini in the analyzer. These are the configuration files.

Only the metal nut should turn. 5) Release the nut and center part from the O2 sensor manifold part (it can only be disasembled once the nut is fully unscrewed).
  • Page 56 6) Remove the O2 sensor electrochemical cell from the Vacuum package and install it in the O2 sensor manifold. Grill part of the Cell should face the manifold and gold contacts should face 7) Re-install the Nut and center part together on the manifold. Screw-in the nut without twisting the center part (to no damage the cable).

    11.Options 11.1 RS232/RS485/Profibus communication The RS-232 option is used to monitor the values and the status of the analyzer. A female DB-9 connector is available on the back of the LD8000 when the option is installed. Baud rate: 9600, 19200, 38400, 57600 bauds (see section 7.5, admin menu, page 4) The string coming out of the serial port is ASCII.
  • Page 58 A RS-485 communication can also be available by installing a RS-232 to RS-485 converter module. The RS-485 can then be accessible by connecting the TX and RX wires in the terminal block of the converter module mounted on the back panel of the analyzer. The module is powered by the analyzer itself.
  • Page 59 The module provides a fully buffered serial interface between Profibus and peripheral devices. Internal FIFO’s, buffer up to 255 bytes for both receive and transmit data, easing the interface for slower RS232 based devices. Hardware or software flow control is supported. See on the image below our RS-232 to Profibus converter module.

  • Page 60: Integrated Stream Selector & Auto Calibration

    11.2 Integrated stream selector & auto calibration The integrated stream selector is used for selecting the desired stream from the LD8000 Multigas interface. The compact stream selector system is mounted inside the LD8000 Multigas and is certified and tested for high purity. It can have up to 5 different streams. Mostly, one stream is used for zero gas, a second stream for span gas and the 3extra streams are user’s selectable depending of the number of analysis streams.
  • Page 61 The auto calibration option can also be added to the integrated stream selector system. It consists of having the software interface that gives the benefit to configure an automatic routine for the analyzer calibration. Please refer to the calibration menu snapshot below for further details.
