Pump Status Indicator
The Vertex M Display includes pump status indicators in the top right corner. The bottom row
indicates which of the pumps is currently operating. The indicator will display ON with a green
background if the pump is operating and OFF on a white background if the pump is not
running.
The top row indicates what is known about pump health. The indicator will display GOOD with a
green background if the pump has successfully provided proper levels of system vacuum. If the
Indicator displays BAD on a red background, this indicates that pump related faults 112 or 219
have been generated. The indicator may display UNKNOWN on a white background after
software is installed or after analyzers are added or moved into a different location.
Pumps in the UNKNOWN or BAD state change to the GOOD state only when successfully used
during gas monitoring. After a failed pump has been repaired or replaced, it can be exercised by
pressing PUMP ALTERNATE button while monitoring. See "Flow Calibration" on page 104 for
more information. If successful, the pump state will change to GOOD.
Honeywell recommends that pumps be alternated periodically to insure availability according
to the facility's schedule.
