P13.10 Positioner
Period
{0,2 s}
Variable speed actuators (Bettis RTS CM and Smartcon
CSC FU): Without function Fixed speed actuators
(Smartcon CSC): This parameter is only relevant in Step
mode when approaching the target position (parameter
gain smaller than 100%) and determines the period of a
run / pause cycle.
P13.11 Positioner
Begin pos. (a0)
0.0 -
25.0%
{2.0%}
Smallest controllable position other than the end
position CLOSED. The range 0% - a0 will be just passed
through. Use the parameter a0 to define the beginning
of the allowable control range of the valve (e.g., blind
spot for ball segment valves, etc.).
P13.12 Positioner
End pos. (e0)
75.0 -
100.0%
{98.0%}
Largest controllable position other than the end position
OPEN. The area e0 - 100% is just passed through. Use
the parameter e0 to define the end of the allowable
control range of the valve
P13.13 Positioner
Begin setp. (a1)
0.0 - 25.0%
{2.0%}
Below this value, the end position CLOSED is controlled.
In the range 0% - a1 cannot be controlled (end position
tolerance). The initial setpoint a1 is associated with a
small hysteresis (1/4 of the deadband).
P13.14 Positioner
End setp. (e1)
75.0
- 100.0%
{98,0%}
Above this value, the end position OPEN is controlled.
The range e1 - 100% cannot be controlled (end position
tolerance). The final setpoint e1 is associated with a
small hysteresis (1/4 of the deadband).
