13.3 Sensor / Gas Selection
13.3.1 Sensor Selection
“Select Sensor” sets the identity of the type of mV sensor attached to the XCD RFD when
it does not detect the sensor type automatically.
The available mV sensors:
Cb-6 705 100%LEL remote (UL and CSA Certied)
Cb-7 705 HT 100%LEL remote (UL certied)
Selecting ‘

’ will move the operator to the Select Sensor screen. The rst screen displays
the currently configured sensor. To select a new mV sensor like remote type sensors
use‘

’ to move through the list, and then use ‘

’ to make the selection or discard the
selection and return to menu mode by using abort function. If type of sensor is changed,
calibration prompt will appear to ask if you want to perform calibration.

13.3.2 Gas Selection
Use “SEL gAS” to set the target gas for sensors capable of detecting multiple gases. The
available gases:
Sensor type Gas type Gas Name displayed
Cb-6 Str 1 to Str 8 FLM
Cb-7 Str 1 to Str 8 FLM
705 Sensor 705HT Sensor
705 705HT Calibration gas Adjust to Calibration gas Adjust to
Hydrogen *6 *6 50% Hydrogen/air 50% 50% Hydrogen/air 50%
Methane *6 *7 50% Methane/air 50% 50% Methane/air 50%
Butane *3 *4 50% Butane/air 50% 50% Butane/air 50%
Propane *3 *5 50% Propane/air 50% 50% Propane/air 50%
Pentane *2 *4 50% Pentane/air 50% 50% Pentane/air 50%
Ethylene *4 *6 50% Ethylene/air 50% 50% Ethylene/air 50%
Gas selection is dependent on the type of sensor attached to the XCD RFD. Add provided
chart with common gases. When Cb-6/Cb-7 sensor is attached to the XCD RFD, a user
can select the gas from Str1 (1*) to Str8 (8*). For more information on star rating, please
refer to section 19.2.
