Sampler Set-Up; Proportional-To-Flow Sampling - YZ Systems DynaPak DP-2020N Manual

8. Sampler Set-Up

Proportional-to-flow sampling

In this mode of operation, the Z-200 uses two operator
inputs in conjunction with the 1 - 5 VDC flow input to vary the
time that will transpire between pump strokes.
8.1 Adjust the pump volume adjustment knob to the value
used in the calculation in step 9.1.
Sample pump displacement per stroke
.1cc
.2cc
.4cc
In order for the Z-200 controller to operate in the propor-
tional-to-flow mode of operation it will be necessary to
enter the following parameters:
8.2 Loss of flow input:
(XX.X min) Mode #7 Default 20.0 min
The loss of flow input setting is a predetermined amount of
time that the operator would like to see transpire between
pump strokes in the event that the 1 - 5 VDC flow input
signal is lost.
To set the loss of flow input:
1. Set the mode switch to position #7.
2. Set the data switches to the desired time
in minutes XX.X minutes.
Ex: 20 minutes = 20.0
3. Depress the enter switch to load the
value into memory.
NOTE: the green LED will flash if entry is accepted; the red
LED will flash if not accepted.

NOTE: Time (20.0 minutes) above corresponds to dial setting
shown for the Z-200.1 model. (For the Z-200.10, the time would
be 2.00 minutes - the decimal moves one place to the left).
