8.6.2 Analog
Outputs
The EZT-570S can have up to four analog outputs which can be used to retransmit set points,
process variables or percentages of output from the installed control loops. If your chamber is
equipped with optional analog outputs, this menu item will appear in the Hardware menu. With this
option, electrical connections are provided on the chamber for external connection to each available
output.
Some outputs may be provided for specific control functions depending upon the
design of your chamber. Do not alter these output settings unless you are sure that
they are used for monitoring purposes only. If you have any questions regarding the
use of the output, contact our customer service department for assistance.
The analog outputs can be configured to retransmit signals either in a 0-10V or 4-20mA range. The
minimum and maximum values of the output can be set to correspond to a specific value of the
retransmitted source. The output will retransmit this source linearly from the minimum to maximum
range. To configure an analog output, select “Analog Outputs” from the Hardware menu.
Figure 8-12 Analog Outputs
If more than one analog output is available use the left and right navigation arrows at the top right of
the screen to select the desired output. To make changes to the output’s configuration, select the
desired output type by pressing the “Vdc” or “mA” button to select either a 0-10V or a 4-20mA output
signal. The selections are mutually exclusive, so selecting one input type will deselect the other.
Select the desired loop that the output is to use for the source value by pressing the “Source” button.
A list will be provided with the available loop selections. Select the desired loop by pressing the
on/off button for the loop. The selection is mutually exclusive, so selecting one will turn off the others.
Once the selection is made, press the “Return” button to go back to the analog output setup screen.
Press the function button for the desired loop value that the output is to retransmit. The selections
are the loop set point (SP), loop process value (PV) or the loop percentage of output (%Out). The
selections are mutually exclusive, so selecting one will deselect the others. Enter the “Minimum” and
“Maximum” range of the source value that the analog output is to retransmit and press the “Save”
button once all entries have been completed. If you do not press the “Save” button, all changes will
be lost if you leave the screen or select a different analog output.
