block the pumps/sampling system of the device within 30 seconds.
When the device detects a pump flow block, it will display a PASS message. The startup sequence will
resume.

The device will shut OFF after the customer acknowledges this message by pressing the  button.
Check your sampling system if this occurs and contact MSA as needed.
