Once the correct values are input in the correct fields, select the "Enable” button
on the lower right hand portion of the Manual screen. If this Enable step is omit-
ted, the changes will be lost when you navigate to another screen.
NOTE: When changes to this screen are made and enabled, the Status indicator
will be red for a preset period of time. This time is dependent upon the kind of
change made and the length of time required for the change to become equili-
brated. For example, resetting the permeation chamber temperature from 30°C
to 75°C could require up to two hours to reach equilibration, at which point the
Status indicator will change to green.
Auto Mode
After configuring the Dynacal 235 with at least one permeation tube (refer to
page 14 as required), the user may elect to run an automatic mode of operation.
The auto mode uses the power of the Touch Panel Controller to calculate the set
points required to achieve the available range of concentrations for a given
permeation tube or tubes. Once the user input is complete, the flows are auto-
matically set to achieve the requested concentration of the permeate compound
to the span outlet stream.
In Auto mode, all controlled variables are logged once per minute, with flows,
temperatures, and concentration calculations stored in a database. See the fuller
description in the section entitled "historical Dispay graph" beginning on page 18.
To use auto mode:
1. Make sure that all configuration data has been input. Check that the data for
the permeation tube has been entered properly in the Tubes tab. If there is
more than one tube, ensure that all tubes are entered correctly.
2. Select the “Auto” tab on the left hand side of the display controller.
3. Touch inside the white text box labeled “Compound”. A pull-down menu will
appear, allowing you to select from the tubes that have been installed at the
Tubes tab.
