Description
COMPLETED

EXECUTING

ABORTED
Indicates that the Timer Event was aborted by the user
EXPIRED

timer event.
FLOW RANGE

of the set flow rate for a period exceeding 2 minutes. This
indicates that the system was not able to control the flow at the

reason. Examine the system for disconnected tubing, clogged
orifices, proper sensor operation, calibration errors, and filter
media requirements to determine the source of the problem.
