Valve Coupler Mode Commissioning - Step 1
Set parameters in order to describe the valve used and connected position feedback sensors
(PFCs). Select whether to perform the parameterization manually or with the setup wizard.
1. Set the actuator fail action and PFC parameters manually use the wizard to assist you with
the following parameterization tasks:
• Selecting a valve drive design in the Act. Fail Action parameter.
• Initialization run: Automatic value determination for the Sensor Usage parameter
Note: During the initialization run, the valve is opened and closed once. Ensure, that
your plant is in maintenance mode, before starting the initialization run so you do not
endanger persons and tamper dangerously with the plant process.
• Activation of time monitoring of breakaway and transit times. In this case, the current
breakaway and running times of the valve are determined during the initialization run
and taken over as reference values. The maximum permitted deviation is set to
30 %.
2. Determine the "target mode" of the transducer block.

Valve Coupler Mode Commissioning - Step 2
During the second step of parameterization, you can adapt the valve position information that
was transferred to the function block according to your requirements.
Prerequisite: Set the device in the mode Out of Service (OOS) in order to modify the PV_D
Generation parameter.
You can activate the following diagnostic options:
■
Lead breakage or lead short circuit monitoring for the valve lead.
■
Lead breakage or short circuit monitoring for the PFC lead.
■
Cyclic functional test for the position "open" or "closed".
■
Stroke counter and limit value.
The diagnostic information can be stored in the MIO device via the connected valve and the
connected drive.
After having set all parameters, ensure that no "configuration error" is displayed in the
BLOCK_ERR parameter of the parameterized transducer block.
Note!
Implementing the Setup Wizard
The setup wizard is executed in the device description as a method. Refer to the
documentation of the control system in use for information on how to start this method. For the
use of the setup wizard, we recommend you also read the procedure for manual configuration.
