Block Testing a G7 Multi-Gas Pump Cartridge
Pump block tests are performed when you activate any pumped operating mode (leak check, pre-entry, or pump run) on your device. For more information on selecting your device’s operating mode, see Configuring Gas Detection Modes.
When you are in a pumped mode, you can perform a manual block test at any time by plugging G7’s inlet. This causes G7 to go into low-urgency status, and the screen displays that the pump is blocked. Unplug the inlet. If the device returns to OK status, the device is safe to use.
When performing an automatic pump block test, G7 is in safe mode and gas alerts are not triggered. This prevents triggering false alerts from residual gas in the hose.
