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).
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.
