4.16 Activating an automatic over range
An automatic over range can only be activated for the sensors DrägerSensor CatEx
125 PR (order number 68 12 950) and CatEx 125 PR Gas (order number
68 13 080) with the measurement gas methane.
Prerequisite:
– The measuring ranges %LEL (heat of reaction) and vol. % (thermal
conductions) are calibrated.
1. The automatic over range can only be activated with the Dräger CC-Vision PC
software.
WARNING
Risk of explosion!
Only for CatEx sensors: The automatic over range only applies for methane in the
air. Any other gas composition has an impact on the measured signal, may cause
an incorrect display of the results and may cause permanent damage to the sensor.
► Only use the automatic over range to measure methane in the air.
When the automatic over range is activated, the device automatically switches to
the vol. % range if the 100 %LEL methane range is exceeded.
When the values return to the <100 %LEL methane range, the measured value
display alternates with the transitional phase indicator (circle arrow).
4.17 Hydrogen (H2) added signal (for IR Ex)
The H2 added signal can be adjusted using the Dräger CC-Vision PC software.
Requirements:
– At least one DrägerSensor XXS H
2 HC (68 12 025) is activated. H2 is set as the
measurement gas.
– An Ex channel on the DrägerSensor DUAL IR Ex/CO
2 (6811960) or
DrägerSensor IR Ex (68 12 180) is activated.
– Both channels are set to the unit %LEL/%LEL/%LIE.
–The H
2 added signal is only possible with a DrägerSensor XXS H2 HC and an
IR Ex channel.
When the H
2 added signal is activated, the LEL gas concentrations of both selected
sensors are added together and the result is shown in the display in the place of the
IR Ex display.
An activated H
2 added signal is displayed with a + next to the gas name of the
IR Ex sensor in the display.
