Notes:
•
The typical overall times above are also the minimum BioTector cycle time.
•
It is essential that the tube slopes gently back to the sample point, dips and rises in the
sample tube increases the sample transport time.
•
Any point of the sample tube must never be higher than 7 meters above the sample
point.

Manual Operation:
To manually fill the sampler, press the [A] key on the PLC for > 2 seconds. The PLC latches
this input, and this simulates the operation of the BioTectors SAMPLER FILL command.
To manually empty and purge the sampler, press the [B] key on the PLC for > 2 seconds. The
PLC latches this input, and this simulates the operation of the BioTectors SAMPLER EMPTY
command.
To reset the sampler at any time, press the [ESC] key.
