USING G7’S CONVENIENCE FEATURES
Much like a smartphone, G7 will include convenience features that will make it easier for device users to do their jobs. If G7 is being used in an area where cellphones are not permitted, these features will ensure users do not need to carry multiple devices in the field — G7 can act as an all-in-one solution. The timer and stopwatch features will be available from the both the main menu and the quick-select menu. They will always be available on G7 devices using firmware version 3.450 and higher — it will not be toggleable in the configuration.
TIME
G7 now provides the option of showing the local time on the LED screen. The time will be displayed in the top right of the main status screen. Since this is also where the check-in timer is displayed, the user will have the option to choose what information they would like to see if they also have the check- in timer feature enabled.
How to show local time in the banner display The banner can display the check- in timer or the local time. By default, if your G7 fleet is configured with the check-in timer enabled, the screen will display the check-in timer to ensure consistency with previous behavior.

GAS DETECTION
Included with your G7 Single-gas or Multi-gas cartridge is a calibration cap and tubing for bump tests and calibrations. Alternatively, bump tests and calibrations can be completed using G7 Dock. Only perform bump test and calibrations in a safe environment. For more information and instructions on bumping or calibrating with G7 Dock, refer to the G7 Dock technical user manual.
BUMP TEST
What is a bump test? It is safe practice to regularly test gas sensors by applying the target gas. G7’s bump test also tests the operation of light, sound and vibration indicators. The bump test schedule depends on your company’s safety policy.G7 automatically communicates bump test data to the Blackline Safety Cloud, and will remind you when a bump test is overdue. The bump test schedule is configurable. NOTE: To meet CSA LEL performance standard, you are required to bump test before each day’s use. Blackline recommends you do not exceed 30 days without a bump test.
How do I perform a bump test? 1. Attach tubing to the calibration cap. 2. Ensure the other end of the tubing is attached to a fixed flow regulator on the gas tank. 3. On your G7, press the OK button to enter the main menu. 4. Use the arrow buttons to navigate to Gas options, press OK. 5. Use the arrow buttons to navigate to Bump test, press OK. 6. Press the up arrow to continue. 7. G7 performs an automatic audio and visual assessment to test vibration and lights. 8. You can individually choose which sensors to test. By default, G7 will test all sensors. 9. Attach the calibration cap to your device. 10. G7 will begin to count down from 60. Apply the gas within this time window. 11. Turn gas off when prompted on your G7 screen. 12. Press the OK button to complete bump test. 13. G7 will let you know if the bump test has passed or failed, and when your next bump test is due.
21 ||G7 TECHNICAL USER MANUAL

14. Remove the calibration cap and let your G7 sit until the readings stabilize and your G7 has returned to baseline.
NOTE: If you see a bump test fail message on your LCD screen, try the bump test again. If the error persists, please contact our Customer Care team.
22 ||G7 TECHNICAL USER MANUAL

CALIBRATION
What is calibration? Gas sensors periodically need to be calibrated by applying a known concentration of gas for a set amount of time. This procedure ensures the gas sensor can accurately detect gas levels throughout its operating life. The calibration schedule depends on your company’s safety policy. Blackline recommends not exceeding 180 days without a calibration.
How do I perform a calibration? 1. Attach tubing to the calibration cap. 2. Ensure the other end of the tubing is attached to a fixed flow regulator on the gas tank. 3. On your G7, press the OK button to enter the main menu. 4. Use the arrow buttons to navigate to Gas options, press OK. 5. Use the arrow buttons to navigate to Calibration, press OK. 6. Press the up arrow to continue. 7. G7 performs an automatic audio and visual assessment to test vibration and lights. 8. You can individually choose which sensors to test.By default, G7 will test all sensors. 9. Attach the calibration cap to your device. 10. G7 will begin to count down from 60.Apply the gas within this time window and continue to apply gas for 2 minutes. 11. Turn gas off when prompted on your G7 screen. 12. Press the OK button to complete calibration. 13. G7 will let you know if the calibration has passed or failed, and when your next calibration is due. 14. Remove the calibration cap and let your G7 sit until the readings stabilize and your G7 is calibrated.
NOTE: If you see a calibration fail message on your LCD screen, try the calibration again. If the error persists, please contact our Customer Care team.
Calibration for special cases For gases that require special calibration steps, see the support articles on the Blackline Support site:
How to calibrate O3 and ClO2 sensors
23 ||G7 TECHNICAL USER MANUAL

BUMP TEST AND CALIBRATION REMINDER WINDOW
What is the bump test and calibration reminder window? A bump test and calibration reminder window can be customized from G7’s configuration profile in Blackline Live. This setting will prompt the device to show a bump test or calibration reminder alarm upon startup if one of these tests is due within the configured window of time.
How does the bump test and calibration window work? Enabling this feature will help ensure G7 goes into alarm upon startup instead of while it is in use in the field. If you have a daily bump interval, your bump test will be due in 24 hours. However, if you start your shift 2 hours early the following day, you will not be prompted to bump your device as 24 hours has not elapsed. When it becomes due, you may already be out in the field without bump test materials. If you have a 2-hour bump test/calibration reminder window, G7 will go into yellow warning alarm for bump test due on startup when the bump is due within this 2-hour window.
BUMP TEST AND CALIBRATION LOCK
What is the bump test and calibration lock? In the case that an organization wants to make the device unusable when it is out of compliance, the calibration or bump test lock can be enabled from G7’s configuration profile in Blackline Live. This feature locks the device’s screen and all functionality when a bump test or calibration is due on startup. This means the user cannot use their device in any capacity (including gas readings, SOS latch, message sending) until it has been bump tested or calibrated.
What if a bump test or calibration is due during my shift? If a bump test or calibration becomes due during your shift (not on startup), the device will not lock. This is a safety hazard, since the user will not be able to use G7 to call for help. The device will go into a yellow warning alarm for bump test or calibration due, and the message will display in the banner, but the device will remain fully functional. For more details, see the support article on the Blackline Support site:
Bump test and calibration on G7
24 ||G7 TECHNICAL USER MANUAL

ZERO SENSORS
What is zeroing? If G7 is not reading zero and you know you are in an atmosphere with no gas, your gas sensor readings may have shifted. If this happens, it is best to calibrate your sensors. If you are unable to preform a calibration, you can zero your sensors to reset the baseline. G7 can be configured to automatically or manually zero on start-up when you turn on your device from the configuration profile in Blackline Live. NOTE: The baseline reading for oxygen is 20.9.
How do I zero sensors? 1. On your G7, press the OK button to open the main menu 2. Press the arrow buttons to navigate to Gas options, press OK 3. Use the arrow buttons to navigate to Zero sensors, press OK 4. Press the up arrow to begin zeroing. Do not apply any gas. 5. The LCD screen will let you know once zero is complete
NOTE: If you see a zero incomplete message on your LCD screen you may be in an environment with gas levels, or your cartridge may need replacement.
PID TARGET GASES
What are target gases? Photoionization (PID) sensors can be used to detect a large range of gases. A target gas refers to the specific gas you are using trying to detect. G7’s readings will be adjusted based on the target gas it is configured to detect.
How do I set G7’s target gas? G7’s PID sensor’s target gas is set from the configuration profile in Blackline Live. Under the photoionization detector section of the gas sensor settings card, you can choose an existing target gas or set a custom target gas.
Where do I see which target gas G7 is detecting? The target gas G7 is configured to use can be seen in two places:
On startup In the gas options menu, under gas info > VOC target
25 ||G7 TECHNICAL USER MANUAL

In both of these places, G7’s screen will display the target gas’ name, as well as its correction factor.
GAS ALERT COUNTDOWN
This feature will make it easier to prevent false alarms from being delivered to monitoring services. Gases like CO and O2 can spike and dip very quickly, setting G7 into high gas alarm even when gas levels go back to normal. The gas alert countdown is an optional gas feature that creates a time buffer before a high gas alert is delivered to Blackline Live and to monitoring personnel.
How does the countdown work? Typically, when a device’s high gas threshold — determined in the configuration profile — is crossed, the device will immediately send an alert to Blackline Live. This is done so that monitoring personnel can investigate the incident and follow up with the device user to ensure their safety.
Since the alert is sent immediately, it can create false alarm scenarios where monitoring personnel will be alerted even though the exposure was momentary and the device user is back in a safe area. When the gas alert countdown feature is enabled, the device will wait a configured amount of time before sending the alert. G7 will still display red lights and an alert sound so that the user knows to leave the immediate area. With the gas alert countdown enabled, the banner at the top of the screen will show the remaining time before an alert is sent to Blackline Live. If gas levels return to normal before this time has elapsed, the alert will be cleared. The gas exposure will still be visible in the device history view on Blackline Live but will not appear as an alert in the Alerts list.
How do I set up the gas alert countdown feature? The gas alert countdown feature will be turned off by default. To set up this feature:
1. Log into Blackline Live and go to the G7 configuration profile. In the gas sensor settings section under each individual sensor, there will be two new settings: a toggle labeled “Gas alert countdown” and a dropdown field labeled “Gas alert timeout”.
26 ||G7 TECHNICAL USER MANUAL

2. Flip the toggle on for each sensor you want the countdown enabled for and determine the length of buffer time from the “Gas alert timeout” dropdown.
After the configuration is saved and the devices successfully receive the new settings, the gas alert countdown feature will be enabled. For instructions, see the Blackline Support Centre website and search for Gas Alert Countdown.
USING G7 SENSORS IN COLD WEATHER
G7 is rated to operate down to -20°C (-4°F). G7 will function in temperatures colder than this for short periods of time, but Blackline does not recommend letting the device’s internal temperature drop below -20°C (-4°F). Electrolyte sensors At temperatures below -20°C (-4°F), the sensor electrolyte inside CO, H2S and other electrochemical sensors can freeze over time, reducing the ability of the sensor to give a meaningful output. Storing G7 in a warm and humid (60% relative humidity) environment when not in use will help keep electrochemical sensors running longer. Shocking an electrochemical sensor from room temperature to extreme cold and vice versa can also cause temporary drifts in sensor readings. These readings typically resolve in less than 60 seconds.
Infrared (IR) LEL sensors Sudden temperature and humidity changes may cause condensation within the LEL-IR sensor, which can affect its optics and trigger a temporary baseline drift. Typically, they last less than 60 seconds, after which point the readings will recover and G7 will function as normal. Shocking the IR sensor from room temperature to an extremely cold environment can cause a temporary baseline drift, typically less than 10% LEL. If this drift persists, you can manually zero the sensor in the cold environment. Shocking the IR sensor from an extremely cold environment to room temperature can cause a temporary baseline drift, sometimes reaching overlimit. For more details, see the Blackline Support Centre website and search for Operating G7 in cold weather.
27 ||G7 TECHNICAL USER MANUAL

GAS ALARMS AND ALERTS
Once you have completed a bump test and calibration, G7 is ready to monitor and notify you of gas exposure. Gas detection alarms will notify you with either a yellow warning alarm or a red alert depending on the gas level measured. All settings are customizable in Blackline Live. Speak to your safety supervisor to learn about how your gas features are configured.
YELLOW WARNING ALARM GAS FEATURES
LOW WARNING ALARM FOR GAS
When does G7 trigger a low yellow warning alarm for gas? When gas levels reach the low concentration threshold configured by your safety supervisor, G7 will inform you with a yellow warning alarm. NOTE: A G7 with an O2 sensor will trigger low warning alarms in both oxygen-deficient and oxygen-enriched atmospheres. An oxygen-deficient atmosphere poses a risk of insufficient oxygen for breathing. An oxygen-enriched atmosphere presents an increased risk of explosion. Muting low warning alarms for gas You can choose to mute the sound and vibration portion of an alarm, but the lights will stay active. Persistent lights and recurring sound and vibration are there to encourage you to leave, and help emergency responders to locate you in the event that you pass out or are unable to remove yourself from the area. To mute the sound and vibration portion of an alarm:
Press and hold the up and down arrows for three seconds and move to an area where gas is not present
If you do not leave the area and gas levels remain above the low threshold, the vibration and sound will restart in two minutes
28 ||G7 TECHNICAL USER MANUAL

SENSOR UNDER LIMIT
If a gas sensor’s baseline shifts, its reading will shift accordingly and become unreliable. When this happens, the presence of gas can still be measured, but cannot be converted into an accurate reading.G7 will inform you of a sensor under limit with a yellow warning alarm. Your options to correct reset the sensor’s baseline:
If you are in a clean atmosphere, you can zero your sensors to reset the baseline You may need to perform a calibration to ensure the sensors are accurately detecting
gas levels NOTE: Not all sensors can be zeroed, example: LEL sensor.
SENSOR ERROR
If a gas sensor stops working for any reason, G7 will inform you with a yellow warning alarm. An X on your LCD screen will indicate which sensor or sensors are generating the error message. Power off and restart your G7. If this does not correct the problem, you will need to replace your cartridge.
PUMP BLOCK
If your pump inlet is blocked, G7 will inform you with a yellow warning alarm.
What do I do in the case of a yellow warning alarm?
Read your G7 screen. Press and hold the up and down arrow buttons at the same time to let your G7 know you have read the message. Yellow warning alarms are between you and G7, and will not notify any monitoring personnel if your device is monitored.

HIGH ALERT FOR GAS
When does G7 trigger a high alert for gas? If a gas sensor detects gas levels above the high gas concentration threshold configured by your safety supervisor. NOTE: A G7 with an O2 sensor will trigger red alerts in both oxygen-deficient and oxygen-enriched situations. SHORT TERM EXPOSURE LIMIT (STEL) ALERT An alert will be triggered when G7 detects you have reached the STEL configured by your safety supervisor. STEL refers to the gas concentration that you can be continuously exposed to for a configurable time frame without suffering adverse health effects. TIME WEIGHTED AVERAGE (TWA) ALERT An alert will be triggered if a toxic sensor detects you have exceeded the average allowable amount of gas during a configured period of time, informed by your TWA calculation method. NOTE: The two TWA measuring methods available for use on your G7 are:
OSHA (United States Department of Labor Occupational Safety and Health Administration) or
ACGIH (American Conference of Governmental Industrial Hygienists) OSHA is defined as a rolling average of gas exposure accumulated over an eight-hour period of operation. If the worker is in the field longer, the most recent eight-hour cumulative value is used. ACGIH is defined as the total accumulated average, from four to 16 hours as configured by your safety supervisor.
30 ||G7 TECHNICAL USER MANUAL

OVER LIMIT (OL) ALERT An alert is triggered when a gas sensor detects an excessive amount of gas and can no longer give you an accurate reading. NOTE: STEL, LEL and peak readings are reset on power cycle. To have G7 resume readings instead, this setting can be configured in G7’s configuration profile in Blackline Live.
What do I do in the case of a red alert?
Evacuate the area and follow your emergency safety protocol. Read the information on your G7 screen. Press and hold the up and down arrow buttons at the same time to mute the sound and vibration. If high gas levels are still present, the sound and vibration will return after one minute. Sound and vibration will return until gas levels and averages have reduced or returned to acceptable concentrations. Red alerts are immediately communicated to any monitoring personnel. Muting sound and vibration does not cancel the remote alert sent to monitoring personnel.
31 ||G7 TECHNICAL USER MANUAL

CONFIGURATION MODES
Configuration modes are customized in the G7 configuration profile on Blackline Live. Each profile supports up to a total of five modes. These modes allow G7 to temporarily change its behavior for different situations, and can be turned on and off through G7’s interface. Modes can be configured in the portal so that they are only available when a pump cartridge is installed. To enter a mode, you must complete a successful pump block test.
AVAILABLE MODES
Normal This mode is the configuration you determine for everyday operation. G7 will operate using this mode as a default.
Pre-entry Pre-entry mode is used before entering a space that could potentially contain dangerous gas. This mode can be used with or without a pump cartridge, which will actively draw surrounding air to its sensors and test gas levels.
SCBA This mode is meant to be used when the device user is wearing a self- contained or supplied air breathing apparatus (SCBA/SABA) and is entering an area that is known to have high gas levels.
Leak check Leak check mode can be used when checking for gas leaks in a particular area. This mode ­ like pre-entry mode ­ can be used with or without a pump cartridge.
High risk This mode is unique in that it is meant for general high-risk situations, such as an evacuation or travelling through a dangerous area. Unlike the other modes, you will never be timed out and must exit it manually.
Pump run This mode is unique in that a multi-gas pump cartridge is required to use this mode, and it runs the pump continuously ­ such as for use in a hole- watch situation. Unlike the other modes, you will never be timed out and must exit it manually.

CARTRIDGES
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 Customer Care team or your distributor.
CHANGING CARTRIDGES
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. 5. Replace screws into each side of the device. NOTE: Cartridges should always be replaced with a manual (not electric) screwdriver in order to avoid damage to the device’s plastics.
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 in close proximity to 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.

LEL SENSOR PRECAUTIONS
For safety reasons this equipment must be operated and serviced by qualified personnel only. Read and understand the instruction manual completely before operating or servicing.
High off-scale readings may indicate an explosive concentration. Calibrations must only be performed in areas free of flammable gases. Blackline supports three different LEL sensor technologies:
Non-Dispersive Infra-Red (LEL-IR) This is recommended for use in inert environments without oxygen. This sensor does not detect Hydrogen or Acetylene.
Molecular Property Spectrometer (LEL-MPS) By default, the calibration process will validate and ensure accuracy without adjusting the MPS sensor readings. This sensor is factory calibrated for optimal accuracy and we recommend using the factory calibration for the lifetime of the sensor. Advanced users can perform a full calibration with a span adjustment by configuring this in Blackline Live, but this may negatively impact the accuracy of other gases. 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. Oxygen levels below 18% negatively impact accuracy. This sensor is not intended for inert environments and Blackline does not recommend using the sensor when oxygen levels are below 10%. The LEL-MPS sensor will auto-zero at startup, and must be started in clean air.
Catalytic-bead pellistor (LEL-P) Any rapid up-scale reading followed by declining or erratic reading may indicate a gas concentration beyond upper scale limit which may be hazardous. Blackline does not offer this LEL sensor anymore.
36 ||G7 TECHNICAL USER MANUAL

Blackline’s LEL sensors can be calibrated with the following settings:

Gas Methane (CH4)

Calibration concentration (%vol)
2.5%

Calibration concentration (%LEL)
50%±2%

Balance (±5% tolerance)
O2 18% CO 100ppm H2S 25ppm N2 Balance

No known gases desensitize or contaminate Blackline’s LEL sensors. Blackline’s LEL sensors do not cause any EMI interference, and are not negatively affected by EMI of up to 8W.

LEL LATCHING ALARM
Enabling the LEL latching alarm setting means G7 will not stop alarming when LEL sensor readings return from the high alarm threshold. The device user must manually cancel the alarm by pressing and holding on the G7’s up and down arrow buttons for three seconds. If the LEL gas alarm is not canceled by the device user, it will continue until the battery is depleted.
How do I enable the LEL latching alarm? 1. From the gas status screen, press OK twice to enter the Main menu 2. Use the up and down arrow buttons to navigate to Gas info 3. Press OK to enter the Gas info menu 4. Select Gas options 5. Select LEL latching from the list and confirm your selection
The setting you have chosen for LEL latching alarm will remain in place until it is changed manually. It will not be affected by power cycling the device or downloading future firmware updates.

37 ||G7 TECHNICAL USER MANUAL

MULTI-GAS PUMP CARTRIDGE
Using Pump
How do I turn pump on? 1. Ensure G7 is equipped with a multi-pump cartridge and
pumped modes, such as pre-entry, leak check or pump run 2. From G7’s main or secondary menu, select the pumped mode you wish to enter 3. Attach tubing, and perform a block test by following the instructions on G7’s screen 4. G7’s screen will invert, and the pump icon will show in the info bar to let you know pump is running
How do I turn pump off? To turn pump off, enter any non-pumped mode, such as normal, SCBA or high risk mode.
Where do I see my pump details? When a pump cartridge is attached to G7, you can see the pump status screen by pressing the up or down arrow from G7’s main screen. Here you can see if pump is on or off, your hose length, flow rate and sample time (if enabled).
How do I bump test or calibrate my pumped cartridge? Manually bump testing and calibrating pump cartridges is done using the same calibration cap and method as G7’s multi-gas cartridge. Please see “How do I bump test?” on page 23 for stepby-step instructions. G7 cannot be bump tested or calibrated through the pump itself. Bump testing and calibrating with a G7 Dock requires an updated G7 Dock unit. You can tell if your Dock is an updated unit by checking that its unit ID is Dock-P.
How do I perform a block test? You will be asked to perform a block test upon entering any pumped mode, such as leak check, pre-entry or pump run. Follow the steps on G7’s screen to complete the block test. If you do not pass the block test, you will not be able to enter the mode. IMPORTANT: When performing an automatic block test, G7 is in a safe mode where gas alerts will not be triggered. This prevents triggering false alerts from residual gas in the tubing.
38 ||G7 TECHNICAL USER MANUAL

When you are in a pumped mode, you can perform a manual block test at any time by plugging G7’s inlet. This will cause G7 to go into yellow warning alarm, and your screen will let you know that your pump is blocked. Unplug your inlet, and if the warning alarm silences, you know that your equipment is safe to use. What is flow rate? Flow rate is the speed at which air is passing over your device’s sensors. In order to provide accurate gas readings, flow rate needs to be above 150 ml/min. A flow rate less than 150 ml/min will result in a pump block yellow warning alarm. By default, Blackline’s pump aims to maintain a flow rate of 300ml/min and G7 will automatically adjust its pump speed to maintain this rate.
39 ||G7 TECHNICAL USER MANUAL

PUMP OPTIONS
Settings for pump can be found in G7’s main menu, under Settings > Pump options.
What is the sample timer? The sample timer is the amount of time it takes for one air sample to be pumped to your sensors. This calculation is based on your hose length. If sample timer is enabled, the pump status screen will show a countdown and beep once when a sample cycle has completed. The sample cycle will repeat continuously until you turn pump off. If disabled, the sample timer will not show and the device will not beep, and pump will continue to function normally. Blackline recommends a 120 second sample time for 10 feet of tubing, with an additional second per foot of tubing.
How do I enable or disable the sample timer? 1. Press OK to enter G7’s main menu. 2. Use the up and down arrows to navigate to Settings, press OK. 3.
