Multi-Bottle Flow Composite Programs
*10 Flow Mode - Multiple Bottle Composite
The *10 mode augments basic flow mode by allowing Multiple Bottles per Sample and Multiple Samples per
Bottle to be used together. Normally they are mutually exclusive but *10 combines the two, using Flow with
Multiple Bottles per Sample as the base. It adds Multiple Samples per Bottle by letting the user place multiple
samples (1-99) in the same bottle creating a composite sample. NOTE: The number of samples should be
equal to or less than the volume of the sample containers divided by the volume of the sample, to prevent over
filling. The unit operates by accepting contact closures from an external device. Whether those contact
closures are based off Flow, pH, Level, ORP, DO etc. is transparent to the sampler. The unit simply
acknowledges a contact closure was received and that in turn triggers the sample collection process. In *10
the sampler does not control totalization, logging, or the meeting of certain parameters, etc. so they must be
done by the external device. Once the parameters have been met, a contact closure will be output to the
sampler. Every time a contact closure is received, the sample collection process is initiated. The unit will
advance the spout, draw its samples and place them in the correct bottles. It will then wait for the next contact
closure. This will continue until the total number of bottles the unit is configured for (set in *99) each have a
sample placed in them or a bottle full condition occurs. If either of these two conditions are met, the sampler
ends the program.
For example, assume the sampler is configured for 24 bottles and Samples per Bottle is set to 3 (see step by
step programming below). The sampler, after receiving a contact closure, will in rapid succession place 1
sample in each bottle it is configured for (set in *99). In this case, since the sampler is configured for 24
bottles, a total of 24 samples would be deposited (one in each bottle). After depositing this set of samples the
unit would pause awaiting the next contact closure to place the second set of samples in the bottles (there
would be 48 total samples taken after the second contact closure - 2 in each bottle). After the third set, the
sampler would end the sequence and wait for a new program (there would be 72 total samples taken - 3 in
each bottle).
The override time causes the unit to take samples if the contact closure fails to occur. The override time starts
counting down immediately after pressing <START>. If a contact closure is received, the override time resets
and immediately begins to count down again. NOTE: This means that the override time must be longer than
the time it takes for the sampling sequence to complete. If it is not, the override time will elapse while the
sampler is in the sequence causing the sampler to immediately start another sequence after it finishes the
previous one.
Display on LCD Explanation
SAMPLER READY
04/30 04:30:02
This display indicates the sampler is ready to program and displays
the current time. Press the * key to begin programming.
ENTER * MODE
__ __ 04:30:02
The sampler is now prompting for a star mode to be input. Enter the
numbers which represent the star mode of choice, in this example 10,
and press <ENTER>.
