Assigning I/O Functions
The inputs and outputs must be configured before use. By default, the unit does not ship with
any relay configuration. To configure the inputs and outputs, you will need to use the PC
software application.
I/O Status
Figure 53: I/O Status screen
The I/O Status screen shows the current state of the physical inputs and outputs to the EYFR03.
If you have not configured the I/O, this screen will just say "I/O not configured" instead of
showing the inputs and outputs as pictured above. If you have configured the I/O and this screen
shows another message, please contact product support.
Once the I/O is configured, the screen will show the state of each input. A high input or output
will be filled in with green. A low input or output will be filled with yellow.
Inputs
The inputs of the EYFR03 qualifier take 3.3-24VDC and have low current drain. The discrete
I/O has a single common pin for all inputs and a signal pin for each input. The inputs can be
used to select an item to run or control the qualifier.
The selection inputs should not be used when the unit is being controlled by a network protocol,
as this will generally result in unexpected behavior. Some control inputs, notably the suspend
input, may also cause unexpected behavior when used along with a network.
Selection inputs
Select Parameter #X
Inputs used: 1 per parameter
This input selects a parameter when activated. One version of this input exists for each of the
100 available parameters (Select Parameter 1, Select Parameter 2, etc.). If the parameter is not
configured with a valid tool, activating an assigned input will do nothing. Deactivating the input
does not stop the parameter. The parameter will remain selected until the parameter is stopped,
or another parameter, group, or job is selected.
