A.10.6. Define Digital Outputs
Digital outputs can be programmed. The following screen shows one logical
function per time, and allows the user to assign it to a physical output. The
NEXT key scrolls between the logical functions. The NC/NO key selects the
Normally Open (NO) or Normally Closed (NC) status of the output. Normally
Open means the output is not energized in normal conditions. To program a
function, scroll with NEXT until the function is displayed, then enter the
number of the physical output and confirm with ENTER; finally scroll with
NC/NO until the desired mode is displayed. By assigning a function to 0, the
function is disabled.

The following table shows the available logical selections that can be assigned
to any available physical output. Typical field wiring drawings and customer
specific field wiring drawings show Ready defaulted to #1 NC, Alarm defaulted
to #2 NC and Totalizer (remote counter) defaulted to #3 NO. Default selections
can be reassigned to any physical output if desired.
Logical selections should not be reassigned after the physical outputs have been
wired.
CAUTION
LOGICAL SELECTIONS RETURN TO THE DEFAULT IF THE
INTEGRATOR IS COLD STARTED.
