4-2-2 Auto Setup
Auto setup is a function that automatically performs basic adjustments and setup after
the device is assembled onto the actuator.
Select [Device]→[Basic Setup]→[Auto Setup].
Cautions
It is dangerous during auto setup because the fully closed valve moves to fully open. Be
prepared in advance to prevent injury and effects on the process when the valve moves.
Handling Precautions:
- The input signal should be 5 mA or more. If it is less than 5 mA, auto setup
may not operate normally.
- If any of the self-diagnostic messages shown in Table 4-5 in 4-2-20,
“Diagnostic Messages” appears, auto setup cannot be executed.
- When auto setup and zero span adjustment are complete, change the input
signal and be sure to check valve operations such as opening and shutoff.
- Before the Auto setup operation, set the position of the actuator type and the
forced close feedback lever correctly.
- In some cases, the dynamic characteristic is not set correctly with the actuator
capacity, operation stroke, inner diameter of pneumatic piping and piping
length. If this occurs, refer to '4-2-5 Control Configuration' and adjust the
dynamic characteristic manually.
- When the actuator size is Custom, the size is not changed with the Auto setup.
When selecting the actuator size with the Auto setup, set the size as below.
Param 1 to 6 or
Param A to C.
- In some cases, the initial setting is not same even though the actuator and
valve size is same. Please perform the operation check and configuration of
the device if necessary.
- There is a possibility that the forced open value described on page '4-2-7
Travel Cutoff' may change after performing the Auto-setup operation. Please
reconfigure the forced open value if necessary.
- If the booster relay is on, and is operating the Auto-setup function, there might
be a possibility of hunting. In this case, adjust the booster's sensitivity, or refer
to '4-2-5 Control Configuration and adjust the dynamic characteristic manually.
- If a speed controller is incorporated, set it to full open and execute auto-setup.
Afterwards, adjust the speed with the speed controller.
- When the device is purchased separately, its initial settings are set to those
in the list of default values in '6-7 List of Default Values for Internal Data' of
this manual. Because the default actuator direction is reverse, if you mount
the device on the direct actuator the device will not work. Please be sure to
execute the auto setup program before operation and be sure that appropriate
settings are created in the device.
Check the Actuator Type and Valve Closed Position before starting auto setup.
The Actuator Type is set to Linear and the Valve Closed Position is set to Down when
the valve is fully closed at the time of shipment unless there are other shipment setup
instructions. If factory setting (initial setup) is requested, check the settings at the time of
shipment. Configure settings as needed.
