Dependent parameter

Options:

7.9.3

Enable manual valve override

Options:
Manual valve override is enabled using this parameter. This feature is used to specify valve control values
directly; the control value from the controller is overridden. This action may be necessary during the
commissioning phase, for example, to test the function of the system. A further possible application is the
specific overriding of controller.
•
no: The manual valve override is deactivated
•
Yes: The manual override is enabled. The two group objects Enable/disable manual override valve A
and Override valve control value are enabled. The former is used to activate or deactivate the manual
override. The manual valve control value is specified using the second group object. Only if the
manual override has been activated via the first group object is the value in the second group object
sent to the valve. As soon as the manual override is ended using the Enable/disable manual override
valve A group object, the valve output reacts again to the controller (controller mode) or the control
values received via the bus (actuator mode).
As soon as the manual override is activated via the Enable/disable manual override valve A group object,
the value currently in the Override valve control value group object is written to the valve. If, while the
override was disabled, a value was written to this group object, this value will become active as soon as
the override is enabled.
