IB140012EN

The I/O's are programmed similar to the setpoint programming. 

The user may view the I/O's programmed by going into the View 

Setpoints area or one can program the I/O, including the I/O Mod-

ule by going into the Change Setpoints Menu.  Figure 12 shows 

the Programmable Inputs screen. Figure 13 shows the Program-

mable Outputs screen. Programming an I/O module is done in the 

same manner. Figure 14 shows the Module's final programming.  

Be sure to press the enter key when you have completed each 

input (or output). “Save” your choices for each Module before 

changing screens, or your settings will be lost.

Figure 14. I/O-Module Display Example

When the I/O is "Fixed" the display will show the particular I/O in 

the designated slot.  The display will show a fixed I/O as black 

instead of blue.
Table 8 shows the features and the I/O of the controller. There are 

several more switch features and options not shown in Table 8. 

See Appendix B for more information and definitions. This IB is 

updated during the year but some features may not be shown 

because of the time element of the IB getting published.  Eaton is 

constantly adding in more features to the ATC-900. As men-

tioned, the user will receive all software features except for the 

optional closed transition.The "P" and "S" (programmable, stan-

dard) included in all ATC-900's.The difference is that the "P" 

refers to the I/O programming.  If the switch requires more I/O 

than 4 in or 4 out, an I/O Module will be required. The right col-

umn shows the I/O required for that particular option. 
The fixed I/O is required when a switch on the door may be used 

to enable an option.  An example would be a two position switch 

on the front of the door to enable Load Shed.
