Brief Operating Instructions for TZID-C With Software Rev. 1.1 and Lower
Commissioning
1. Turn on the air supply to the positioner.
2. Apply the 4...20 mA analog input signal to the positioner.
3. Check for proper mounting: refer to instruction manual if needed.
• Open front dust cover from positioner to access the local control keys.
• Press and hold MODE.
• Additionally briefly press or until mode 1.3 MAN_SENS is displayed.
• Release MODE.
• Press or to move the actuator to its mechanical limit stops in both directions, and note the values.
The angle of rotation on the display is indicated in degrees. Recommended positions of limit stops:
> -28° and < +28° for linear actuators
> -57° and < +57° for rotary actuators
• Adjust the mounting position of the positioner in relation to the actuator if required.
Configuration
4. Switch to the configuration level:
• Press and hold or simultaneously.
• Additionally briefly press ENTER.
• Wait until the countdown from 3to 0is completed.
• Release or .
The device will automatically go to program level “P1.0”
5. Select the actuator type “ROTARY” or “LINEAR” using or .
Note: This Step must be done prior to Autoadjust (Step 6)

QUICK-START
6. Start Autoadjust:
• Press and hold MODE
• In Addition briefly press until "P1.1" is indicated.
• Release MODE.
• Press ENTER and keep it pressed until the countdown from 3to 0is finished.
• Release ENTER Autoadjust is now activated; the complete process will take a few minutes.
• When the message "COMPLETE" is displayed to indicate successful Autoadjust, briefly press ENTER to
acknowledge. It is also possible that Auto-adjust is cancelled due to errors detected during this procedure; the
applicable error message is displayed. Refer to Instruction manual for error codes and details.
7. Save the settings:
• Press and hold MODE.
• In addition, briefly press until P1.4 “EXIT” is indicated.
• Release MODE.
• Select NV_SAVE using or .
• Press and hold ENTER until the countdown from 3to 0 is completed, then release ENTER. The settings are
saved in the non-volatile memory, and the positioner returns to the operating level.
Selecting the Operating Mode
Mode 1.1: Fixed control
• Press and hold MODE.
• Additionally briefly press as often as required until level 1.1 “CTRL_FIX” is displayed.
• Release MODE
• Positioner is now active in the FIXED control mode.
Mode 1.2: Adaptive Control
• Press and hold MODE.
• Additionally briefly press as often as required until level 1.2 “CTRL_ADV” is displayed.
• Release MODE
• Positioner is now active in the ADAPTIVE control mode.

QUICK-START
Advantage of Adaptive Control Mode:
The positioner incorporates a unique “Adaptive Control” mode that will allow a “Selftune” function within the posi-
tioner to determine the best control parameters for the application (This process is independent of the PID control
settings needed in the DCS or controller to obtain loop control stability). The positioner will optimize the control per-
formance by adjusting the control parameters automatically as the dynamic conditions of the valve changes due to
process load demand changes.
In any application the process control performance is largely dependent on the control valve and the condition of
the valve. For this reason the valve needs to be in a “good” condition to ensure the optimum performance of the
Adaptive control mode.
Any deterioration of valve performance due to increased friction stick of the valve stem, cylinder shaft or stem/dia-
phragm leakage will cause the positioner to “adapt” to the changed valve condition in a attempt to optimize the per-
formance, however, this optimization does not represent dynamic process changes, in this case the positioner will
consistently optimise until the stem friction or deterioration has increased to an undesirable level. In this case the
positioner is unable to provide reliable control due to problems beyond its control. If the “TIME OUT” diagnostic
alarm of the positioner is active the positioner will provide a binary output as an alarm function when the set point is
not reached within the preset time. This “time-out” time can be adjusted. Refer to instruction manual “Alarm mes-
sages” for details.
In the case of the “Fixed Control” mode, the positioner will consistently position the valve with the control parame-
ters detected during the AUTOSTROKE process. It may become a consideration by the user to switch from the
“Adaptive Control” to the “Fixed Control” mode once the TZID-C was optimized as explained above.
The TZID-C also allows the user to access the control parameters manually via the front push buttons on the TZID-
C or via the ABB Smart Vision software tool to perform custom optimization that may be required in some extreme
cases when the standard AUTOSTROKE or Adaptive Control was not able to optimize the application.
The TZID-C Positioner is now ready for operation.
