Instrument Power On and Communication Symptoms
MSD turns on but then the foreline pump shuts off
MSDs will shut down both the foreline pump and the high
vacuum pump if the system fails to pump down correctly. This
is usually because of a large air leak: either the sideplate has not
sealed correctly or the vent valve is still open. This feature helps
prevent the foreline pump from sucking air through the system,
which can damage the analyzer and pump.
You must power cycle the instrument to recover from this state.
