I/O setup is normally performed only once, before field connections are made to the Analyzer/Controller. You can also use this menu to view parameters. If you do not change anything, you will not cause a cold reset of the unit. You can exit now using the MENU key. If you go past this “Attention” screen, you must go through the entire sequence of I/O setup screens before returning to the main menu.
Go to the next screen.
Specify whether AutoClean should be enabled. If YES, a relay will be dedicated to this use.
Specify whether you want to use a relay to indicate when the range shifts for the analog output based on Cell 1’s input. (Output scaling is specified in Step 13.) If YES, a relay will be assigned to indicate when the Cell 1 range switch occurs.
Go to the next screen.
1If the system uses a DE option card, no analog outputs are supported by the hardware. The screen will show “DE ENABLED”, instead of displaying output assignments.
