7. Basic settings for commissioning
Definition
Basic settings such as type of seating, torque and limit switching are required for
safe commissioning of the actuator controls together with the actuator. Basic settings
for display, such as date and time or display formats, can be changed, if required.
7.1. Type of seating for end positions
Function
●
Selection of the type of seating (according to valve manufacturer's specifications)
- Limit seating in end position
- Torque seating in end position
●
For end positions OPEN and CLOSE, the following can be set individually:
Limit seating
The controls switch off the actuator in the end positions (OPEN/CLOSED) set via
limit switching.
For end position seating via limit switching, you have to account for the overrun of
the actuator. Overrun [1] is the travel from switching off until complete standstill.The
overrun depends on the inertia of both the actuator and the valve and the delay time
of the controls.

[1] Overrun
Torque seating
The controls switch off the actuator in the end positions via torque switching.
For this the torque switching has to be set to the tripping torque specified by the
valve manufacturer.When reaching the end position, the torque increases within the
valve seat. As soon as the set tripping torque is reached, the controls automatically
switch off the actuator.
In this context, the limit seating is used to signal that the limit switching will trip shortly
before reaching the end position.
