Available values for the time in these fields are 0 - 99 min. For the pin

Spark Marathon user manual.
Flush Mode
Allows to set the injection mode by selecting one of the possibilities. Note
that the available options differ according to the sub-type of the autosampler.
The options are:
fFlushed Loop - in this mode, the full sample loop will be transferred to
the column.
Partial Loopfill - in this mode, only a part of the sample loop with the
volume defined on the particular row of the Sequence Table will be
transferred into the column.
Flush Time
When this field is checked, the loop is filled based on time by the
overpressure instead by the dispenser pump. The injection volume in
sequence then corresponds to time in seconds for partiall loopfill.
Preflush Volume [μl]
Defines the volume of the sample used to wash the needle and tubes before
the injection valve is set to the load position. Possible values range between
50 and 999 μl in the Partial Loopfill mode and between 30 and 999 μl in the
Flushed Loop mode.
Needle Wash
Defines whether the needle wash will be performed. The wash is performed
after each injection, the flushing solvent will be taken from one of the wash
vials (vials number 93 - 96). The option is disabled when the Large Sample
Volume option is used.
Note:
Fill all four vials and place them to the appropriate positions as the wash
is taken alternately from them.
Large Sample Volume
Defines the type of the sample tray used with the Spark Marathon
autosampler. When the standard tray (for 96x1,5ml vials is used, this option
should be unchecked, as opposed to the usage of the 48x5 ml tray.
Tray Cooling On
When checked, the optional sample tray cooling is switched on. The cooling
is set to the temperature of 4 °C.
Oven Temperature [°C]
Allows to enable the oven temperature function and set the temperature for
the oven (in the range 0 - 90 °C, the instrument can only control
temperatures at least 5 °C above ambient temperature or more). The Spark
Marathon autosampler will wait with the injection until the set temperature ±
