    EN50081-2 (generic emission for household appliances and the light industry) and EN 50082-2 (generic immunity for the industry). The sensor element of the TCOD-IR operates by the principle of infrared absorption. This principle provides : - precise &...

  • Page 8: Structure Of The Tcod-Ir

    PTFE-Foil Viton Seal The TCOD-IR should be mounted in a suitable position, eg on a wall, with the opening of the transmitter pointing downwards. Allow a 10 cm gap between the head of the transmitter and any other object for calibration.

  • Page 9: Calibration And Adjustment

    The voltage at the measured points X2:S1 (ground) and X2:S6 of the service terminal is measured with a voltmeter (set mV DC). OLDHAM EQUIPMENTS The voltage is set to 0 mV DC with the potentiometer U0; voltage may indicate either positive or negative values.
  • Page 10 • Zero-Point Adjustment at Output Signal = 4 mA (Potentiometer Z (Zero)). (The sensor is subjected to zero gas with a volume flow of 0,5l/min.). Using an ameter (set to mA DC), the voltage is measured across the signal path of the "mA" terminal (positive) , note, - the cable must be disconnected from this terminal.

  • Page 11: Test Gases

    Only certified test gases must be used. For calibration, the test gas concentration must be known to ± 2% relative to the bottle value. Zero gas: 100% Vol. N (nitrogen) Standard Test Gas: (carbon dioxide) above 2nd alarm level or in upper third of measuring range.
