    Average charging time: 2 hours 30 minutes 1.2. Memory saving A second lithium battery ensures the storage of the MX 2100's specific data, such as when the main battery set is completely discharged. This lithium battery has an average service life of five years.

    EEPROM memory in which OLDHAM has stored the cell's specific characteristics (measuring range, various correction coefficients, STEL and TWA alarms, date of manufacture, serial number, etc.). Another item of data called the "wear rate" is used by the MX 2100 to automatically determine the optimal time to replace the cell.

  • Page 7: Visual Indications

    N.B. On option, the MX 2100 can be equipped with a vibrator. The MX 2100 can be equipped with a sampling system to measure gas concentrations either in normally inaccessible locations or before entering places which may be contaminated by gas (such as tanks, sewers or tunnels ).

  • Page 8: Carrying The Mx 2100: Options

    The MX 2100 can be connected to a computer via a cable equipped with an infrared port which is plugged into the charger module.

  • Page 9: Twincall" Calibration Station

    " " Checking of the MX 2100 can be performed using a testbench which delivers test gases to the MX 2100 in order to place the channels in alarm status. The MX 2100 detects the presence of the bench and indicates, on the display unit, the faulty channel or channels where alarms were not triggered.

  • Page 10: Reading Measurements

    If there are no toxic cells, the Oxygen and Explo. measurements will be displayed at the top of the dial. REMINDER: Before switching on the MX 2100, check that the necessary cells are connected. When you switch the appliance on, you have a choice of two procedures: •...

  • Page 11: Switching On With Choice Of Reference Explosive Gas

    The reference explosive gas is now the gas that was selected. If you do not validate any gas, after a certain time, the MX 2100 switches to the test phase and to the normal scanning phase without changing the reference gas, so that the procedure is aborted.

  • Page 12: Display Unit Lighting

    The display unit is then lit up in backlighting mode so the data can be read easily. This lighting is automatically deactivated after 30 seconds. The lighting function can be used in dangerous environments, i.e. containing explosive gases as the MX 2100 guarantees intrinsic safety.

    In this way, as soon as the predefined alarm thresholds are exceeded on at least one channel, the MX 2100 triggers an audio and light signal. The alarm message or messages (FAULT, ALARM, TWA, STEL, min., etc.) and the...

  • Page 14: Fault Alarms

    • Normal operating conditions can be restored by stopping and restarting the MX 2100. • Caution must be exercised in the area owing to the presence of explosive gases exceeding LEL.

  • Page 15: Acknowledging Fault Alarms

    8.3. Memorizing histogram measurements Depending on the version, the MX 2100 can memorize measurements so they can be restored later on a computer. The "Histogrammes" (Histograms) function can be used to output values and events memorized by MX 2100 during its operating period to a computer (a workstation, for example).

  • Page 16: Operating Principle

    To make the best possible use of the data output when histograms are printed, you must understand the operating principle of data memorization. Items memorized: The MX 2100 stores sets of data when it is switched on and then in cyclic mode. Each of these data sets has the same structure and contains the following: •...

  • Page 17: Special Instructions For Use In Atex Explosive Atmospheres

    All servicing, adjustment and maintenance operations must be performed by duly approved personnel. IMPORTANT: The MX 2100 is a safety appliance and, therefore, it must be calibrated at least once a year and according to its utilization. The user will automatically receive a maintenance reminder every six months.

  • Page 20: Cell Calibration Menu

    This menu is used to regularly calibrate the cells connected to the appliance. Calibration consists in adjusting the zero of the clean air cell (free of gas which may be detected by the MX 2100) and adjusting sensitivity with a standard gas of known characteristics (including content, etc.).

  • Page 21: Exit Menu

    This system automatically injects standard gases from two cylinders installed in the testbench in order to trigger the alarms. The MX 2100 detects the presence of the testbench and indicates the faulty channel or channels according to the test, on the display panel.
