Description
Operate Mode
Local /
Remote
Remote
This Mode determines if the Archon will
depend on switch signals from the purge
and trap to advance, or be dependent on
the Cycle Timer. In the “Local” Mode,
the Archon will start when the Cycle
Timer parameter, set in the method has
elapsed. NOTE: In Local, the Archon will
NOT respond to switch signals from the
purge and trap, i.e. Standby (Ready) and
Desorb Ready. In the “Remote” Mode,
the Archon responds to the switch signals
given by the purge and trap and the Cycle
Timer parameter. Once the purge and
trap reaches its Standby mode, a signal
output will start the Archon, provided the
Cycle Timer has reached 0.0.
Cycle Timer
0-99.9 min.
00.0 min.
This will advance the Archon from a ready
to sample mode. The Archon starts when
a purge ready signal is received from the
purge and trap, in the standby mode. The
cycle includes the purge time, plus the
GC run time and cool down. The cycle
time is normally used to ensure that the
GC will be ready to receive the next
sample. In the case of short GC run
times, cycle time will not be effective, and
should be set to "0.”
Auxiliary
Timer
0-99.9 min.
00-0 min.
This is a timed event output used to start
or stop additional external equipment.
The timer starts after the sample goes out
the sparge tube for a water or a blank
sample or at the start of the purge for a
soil sample.
Link to
Method
0-30
0-00
The Archon will continue the sampling
sequence for this method upon
completion of the current selected
method. Any combination of methods
may be linked together providing for
continuous operation. Note: Circular
linkage of a method is allowed, i.e.,
linking a method to itself to continually
cycle through one method. Set the
parameter to "0" to stop the autosampler
after the last vial in the method.
