3. To save the changes and leave the window open so that you can monitor the
discrete input’s progress, click Save. The current state of the discrete input displays
in the State column, and is updated in real time.
4. To save the changes and close the window, click OK.
3.5.3 Monitor the operational status of a discrete input
To check a valve’s status, select Discrete Input… from the Hardware menu.
The status of each discrete input displays under the Status column. There are three
possible status readings, and their meanings are as follows:
OK The discrete input is installed and is working correctly.
Not Installed The discrete input is not installed.
Error The Heater/Solenoid board is installed but the GC cannot communicate
with it.
3.5.4 Invert the polarity of a discrete input
The Invert Polarity option reverses the way a voltage signal is interpreted by the discrete
input. By default, the Invert Polarity option is set to Normally Open, which means that a
low voltage signal is interpreted by the discrete input as ON, and a high voltage signal is
interpreted by the discrete input as OFF. Setting Invert Polarity to Normally Closed means
that a low voltage signal is interpreted by the discrete input as OFF, and a high voltage
signal is interpreted by the discrete input as ON.
To set the polarity of a discrete input, do the following:
1. Select Discrete Input… from the Hardware menu.
The Discrete Inputs window displays.
2. Select Normally Open or Normally Closed from the drop-down menu under the
Invert Polarity column.
3.6 Discrete outputs
You can use MON2020 to assign labels to the GC’s discrete outputs and to control the
discrete outputs’ operational modes. The number of discrete outputs available depends
on the GC.
3.6.1 Rename a discrete output
Give each discrete output a descriptive label to avoid confusing one unit for another. To
assign an identifying label, do the following:
1. Select Discrete Outputs… from the Hardware menu.
The Discrete Outputs window displays.
