  • Page 17: Operation

    Operation Device Display The GTR 210 incorporates a graphics display. The upper line of the display indicates the status of the gas transmitter, where faults and alarms are output.

  • Page 19: Alarms

    Alarms In the user menu of the GTR 210, three limit values can be set, each of which triggers an alarm. The first alarm is a pre-alarm, the limit value of which is always lower than that of the main alarm (except for the measurement of oxygen).

  • Page 20: Trend Graph

    Page 16 Trend Graph The GTR 210 comes with 4 different trend graphs that are shown when pushing the arrow keys more than two seconds in the measuring mode. You can switch between the display of the different trend graphs by repeating the activation of the arrow keys.

  • Page 21: Output Signals

    GTR 210 Rev 1.16 Page 17 Output Signals The GTR 210 transmits the measured gas concentration to the evaluation unit via an analogue 4...20 mA current interface. The measuring range of the gas transmitter is transmitted straight proportionally to the current output.

  • Page 22: Systemstart

    On the current output, 2 mA is output (maintenance mode). This is to allow the sensor cell to warm-up and avoid any fault alarm during this time. After the run-in time, the GTR 210 automatically accesses the measurement mode. Maintenance mode (15 seconds remain) MAINTE.

  • Page 23: Exception-State: Sensor-Overload

    Page 19 Exception-state: sensor-overload When using a pellistor-sensor (VQ sensor), the GTR 210 can be in an exception-state. Due to the physical measurement principle, the signal from the pellistor-sensor falls with concentrations exceeding the lower explosion limit. In order to prevent the gas transmitter from indicating a smaller concentration at this time, the exception condition "VQ overload"...

  • Page 24: Exception-States

    ADOS GmbH GTR 210 Rev 1.16 Page 20 Exception-states The GTR 210 gas transmitter has the following exception-states: • warm-up, • calibration, • parameterization (maintenance), • and fault. The measurement of the gas concentration and therefore the output of alarms are interrupted during a exception-state.

  • Page 25: Parameterization Of The Gas Transmitter

    15 minutes. The parameters of the GTR 210 are adjusted by way of a menu. In order to access the menu, the ESC key must be pressed for 4 seconds, then released. In order to protect the measuring device from unauthorized user access, a request is made for the input of a valid code 210.

  • Page 39: Maintenance Operations

    For safety-technical reasons, the sensing head should be checked once each year by a specialist. The maintenance work can be subdivided into transmitter tests of ADOS GTR 210 and testing the evaluation electronics. A check of the calibration, with zero gas and calibration gas, must be carried out on all existing sensors, since the gas sensors age with time and can lose sensitivity.

  • Page 40: Calibration

    ADOS GmbH GTR 210 Rev 1.16 Page 36 Calibration Read carefully, before any calibration: The measuring device must have been in operation for at least two hours before the calibration of the gas sensor! A suitable calibration gas adapter must be used for feeding the test gas. The calibration gas adapter must not produce any pressure on the measurement cell.

    The user must wait until the indicated time has elapsed and the measured value for the zero gas has stabilized. After the time has elapsed, the GTR 210 waits for a user confirmation to check the new value and to accept it, as appropriate. Confirmation with the “ENTER key” should be made only when the user has checked that the measured value has in fact stabilized, i.e.
