2.2 CARTRIDGES AND EXTREME WEATHER
G7 is rated to operate in weather conditions as low as -20°C (-4°F). G7 will function in
temperatures colder than this for short periods of time, but Blackline Safety does not
recommend letting the device’s internal temperature drop below -20°C (-4°F).
For more details, see Operating Devices in Extreme Weather on the Blackline Support site.
2.3 CARTRIDGES EQUIPPED WITH COMBUSTIBLE GAS (LEL)
SENSORS
For safety reasons, combustible gas (LEL) sensors must be operated and serviced by
qualified personnel only. Read and understand the instruction manual completely before
operating or servicing LEL sensors.
WARNING: High off-scale readings may indicate an explosive concentration.
WARNING: Calibrations must only be performed in areas free of flammable gases.
Blackline’s LEL sensors are factory calibrated with the following settings:
Gas
Calibration
concentration (%vol)
Calibration
concentration (%LEL)
Balance (±5%
tolerance)
Methane (CH4) 2.5% 50%±2%
O
2
18 vol%
CO 100ppm
H2S 25ppm
N2Balance
Like any gas sensor, be sure to understand potential explosive hazards and choose the
appropriate sensor technology based on these hazards.
Blackline supports three different combustible gas (LEL) sensor technologies:
•Molecular Property Spectrometer (LEL-MPS)
•Non-Dispersive Infra-Red (LEL-IR)
•Pellistor (catalytic bead) (LEL-P) (EU only)
Blackline makes the following recommendations for the use of each type:
Molecular Property Spectrometer (LEL-MPS)
This sensor is not intended for inert environments. Environments with oxygen (O2) levels
below 18% will negatively impact this sensor’s accuracy and Blackline does not recommend
using it when oxygen levels are below 10%.
NOTE: The LEL-MPS sensor will auto-zero at start-up and must be started in clean air.

13 | G7 Technical User Manual ©2023 Blackline Safety Corp
2023-04-26 Rev. 33
When bump testing or calibrating cartridges containing this sensor, Blackline recommends
applying a gas mixture containing at least 18% oxygen (O2). Less oxygen than this may
impact the MPS sensor’s reading. If a gas mixture with less than 18% oxygen is applied to
this sensor, power cycling the device is recommended.
This sensor can be calibrated two ways:
•Default calibration — The default calibration process will validate and ensure accuracy
without adjusting the LEL-MPS sensor’s readings. Unlike traditional sensors, this sensor
is factory--calibrated for optimal accuracy.
Blackline Safety recommends using the factory calibration for the lifetime of the sensor.
•Full calibration — Advanced users can perform a full calibration with a span
adjustment. A full calibration may negatively impact the accuracy of other gases.
NOTE: No known gases desensitize or contaminate Blackline’s LEL-MPS sensors. The sensor
does not cause any electromagnetic interference (EMI), and is not negatively affected by
EMI, such as radio transmissions, of up to 8W.
Non-Dispersive Infrared (LEL-IR)
This sensor is recommended for use in inert environments without oxygen (O2). This sensor
does not detect Hydrogen (H2) or Acetylene (C2H2).
NOTE: No known gases desensitize or contaminate Blackline’s LEL-IR sensor. The sensor
does not cause any electromagnetic interference (EMI), and is not negatively affected by
EMI, such as radio transmissions, of up to 8W.
LEL-IR sensors are impacted by temperature. For more details, see Cartridges and Extreme
Weather.
2.4 CARTRIDGE MAINTENANCE
2.4.1 GAS CARTRIDGE REPLACEMENT PROGRAM
If you have an uninterrupted service plan for your G7 gas cartridge, Blackline will replace
expired cartridges for you free of charge. To inquire about or request new cartridges,
please contact our Technical Support team or your distributor.

Rev. 33 2023-04-26
2.4.2 CHANGING CARTRIDGES
To change G7’s cartridge:
NOTE: Cartridges should always be replaced with a manual (not electric) screwdriver to
avoid damage to the device’s plastics.
1. Power off G7.
2. Using a Phillips #1 screwdriver, remove the screws on
each side of the device.
3. Pull up on the cartridge.
4. Slide a new cartridge onto G7, ensuring the cartridge
clicks into place.

2.4.3 CARTRIDGE CARE
Gas sensors are susceptible to contamination by a variety of common chemicals, reducing
or eliminating their sensitivity.
Take care when using silicones, cleaners, solvents, and lubricants near sensors as exposure
may cause permanent damage to the sensor. If a device is exposed to a new chemical or
compound, it is best practice to bump test and calibrate units to ensure proper sensor
function is maintained.
For details on preventing sensor contamination, see Cleaning Devices and Accessories on
the Blackline Support site.
2.4.4 CHANGING FILTERS FOR CARTRIDGES
For instructions on how to change filters for cartridges, refer to the following support
