Using the G7 Multi-Gas Pump Cartridge
G7's multi-gas pump cartridge is a plug-and-play cartridge that you can attach to G7. The pump cartridge allows you to actively test different areas prior to entering (e.g., down manholes) to determine if the environment is safe.
The pump cartridge uses configuration modes to enable and disable the pump. G7 has three pumped modes: pre-entry, leak check, and pump run. The pump cartridge is toggled between diffusion and pumped operation by entering and exiting gas detection modes.
Note: If A-CART is installed, G7 devices will only operate in pumped modes, regardless of configuration.
You can configure G7 devices that have firmware version 3.505 (or later) and have a Pump Cartridge F2 installed to automatically enter into a pump mode when the device is powered on, instead of having to turn on pump mode manually. See Editing Configuration Profile Details for more information.
Note: If G7 has older firmware or a diffusion cartridge attached, this configuration setting is ignored.
