Procedure options
After completing the above steps, the XGF868i returns to the
I/O window. Do one of the following:
• To continue programming, refer to
Appendix A. Menu
Maps on page 39 , to navigate to the desired menu.
• To leave the keypad program , press [escape] three times.
1.9.2d Analog inputs
Refer to Figure 31 on page 43 , and complete the following
steps to set up the analog inputs of an option card installed
in slot 1:
Accessing the input
1. In the keypad program , scroll to prog and
press [enter].
2. In the prog menu, scroll to GLOBL and
press [enter].
3. In the global program menu, scroll to I/O and
press [enter].
4. Scroll to optn and press [enter].
5. Scroll to slot 1 and press [enter].
6. Scroll to the desired input and press [enter].
NOTE: Input letters (A, B, etc.) correspond to input wiring
terminal numbers from top to bottom (e.g. input A
corresponds to pins 1,2 and 3; input B corresponds to
pins 4, 5 and 6; etc.).
Setting up the input
1. Enter a label of up to eight characters for input and
press [enter].
2. Scroll to the desired input measurement and
press [enter]. Do one of the following:
• If off was selected, go to
procedure options below.
• If pressure or temperature was selected, proceed
to step 5.
• If special was selected to set up the input as a
live special input, proceed to the next step.
3. Use the arrow keys to enter a name for the input and
press [enter].
4. Use the arrow keys to enter a unit of measurement
for the input and press [enter].
