7. Connect a current meter in series between the AO + and AO–
terminals.
8. Select the Analog Output point from the list.
Using ROCLINK 800, set the output to minimum EU value.
9.
Verify that the current meter indicates the low current needed for the
10.
loop.
If the value does not meet the minimum current required, alter the
11.
Adjusted A/D 0% counts found in the AO point on the ROCLINK
800 screen until it does meet current requirements.
12. Using ROCLINK 800, set the output to maximum EU value.
Using the current meter, verify that maximum loop current is being
13.
supplied.
If the value does not meet the maximum current required, alter the
14.
Adjusted A/D 100% counts found in the AO point on the ROCLINK
800 screen until it does meet current requirements.
15. Set the AO EU value to the range noted in step 5.
16. Connect the field device.
If the AO was used in a PID loop, re-able the PID loop and verify
17.
the operation is adequate.

Failure to exercise proper electrostatic discharge precautions, such
as wearing a grounded wrist strap may reset the processor or
damage electronic components, resulting in interrupted operations.
Ensure that the area is a safe operating environment.
Ensure that the IO point is safe to remove from service.
1.
Connect to ROCLINK 800.

3. Remove the wiring from the termination points.
4. Select Configure > I/O > DI Points.
5. Select the correct DI point number.
Place a jumper between the DI and the ground on the termination

block.
7. Using ROCLINK 800, verify that the status is on. (If the point is
configured for inverted operation the status is off.)
8. Remove the jumper between the DI point and the ground on the
termination block.
