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.

Note:

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.
