Automatic Bump Tests and Calibrations
Blackline Safety offers an Automatic Bump Test and Calibration feature that enables EXO to automatically perform bump tests or calibrations so your device can operate unattended on a worksite.
This feature is not available for EXO Diffusion.
The Automatic Bump Test and Calibration feature requires a service plan and hardware accessories. The required hardware accessories include:
-
EXO 8 Pump or EXO 8 Gamma Pump
-
Solar Panel and the Solar Panel Mounting Kit (ACC-G7EXO-UMK-SOLAR-MOUNT-KIT)
Note:You can use the trickle charger instead of a solar panel to supply continuous power to EXO.
-
Two Gas Tank Mount Kits (ACC-G7EXO-UMK-GAS)
-
Universal Mount Kit (ACC-G7EXO-UMK)
-
Quad Gas 34L gas cylinder
-
Ultra Zero Grade Air gas cylinder
-
A 0.5 LPM demand-flow regulator attached to the cylinder(s)
-
Tubing
-
Inlet Particulate Filter (ACC-INLET-FILTER)
For more information about the automatic feature and the optional hardware accessories, contact your Customer Relationship Manager (CRM).
EXO initiates a bump test or calibration when the test is due. You can configure EXO’s pump inlets 1 and 2 to complete automatic bump tests and calibrations in Blackline Live. Pump inlets 1 and 2 must be connected to a gas cylinder with a multi-gas mixture and the ultra-zero grade air gas cylinder (required for calibrations). Inlets 3 and 4 can be used for gas sampling when automatic bump tests and calibrations are enabled. For more information on configuring automatic bump tests and calibrations, see the Blackline Live Technical User Manual.
The ultra-zero grade air gas cylinder has an O2 composition of 20.9% and N2 for balance. Do not use a gas cylinder with an O2 composition of 18% during calibrations, as it can affect the baseline of the O2 sensor.
Failed Bump Tests and Calibrations
If an automatic bump test or calibration fails, EXO displays a bump test due or calibration due notification. EXO continues to operate with the active notification until you perform a manual bump test or calibration.
Blackline recommends that you set up text or email notifications in Blackline Live to notify you if an automatic bump test or calibration fails, or if a pump block is detected. See the Blackline Live Technical User Manual for more information.
