Fault. A fault may occur when there is restriction in airflow
(e.g., kinked tubing) that remains uncorrected and the pump
can no longer compensate flow, or when battery voltage is too
low. See Fault Mode and Display for details on pump
operation during flow fault.
FAULT!

skcinc.com PDP0008 Rev 0 Page 18
Fault Mode and Display
During a sample run, overloaded sampled media or kinked tubing can restrict airflow and cause back
pressure to build to a point at which the pump can no longer compensate flow within ± 5%. This also may
happen when battery voltage is too low to maintain set flow. If this condition is sustained for 3 to
10 seconds, the pump will go into fault mode as follows:
1. The pump stops sampling and status LEDs on the pump flash red. Elapsed time stops and
“FAULT!” is displayed on the screen.
2. After 20 seconds in fault, the pump will attempt to restart up to 5 times.
a. If full airflow is restored during the restart attempts, the pump will continue the sample
run.
b. If full airflow is not restored during 5 faults and four restart attempts within 5 minutes, the
pump will end the sample run. The LEDs will flash red with decreasing frequency.
3. The fault screen below will be displayed. Touch the check mark to clear the flow fault and return
to the Sample menu.
