0 – 100% Determination of the emergency position. (it can also be

Calibration value for the mA setpoint. Calibration process:
-10% -
By applying 20 mA on the setpoint input, this parameter
+10%
is corrected until the readout matches 20 mA.
Variable speed actuators (RTS Compact Multi-Turn CM
and Smartcon CSC FU): Without function
Fixed speed actuators (Smartcon CSC): Minimum
activation time of the reversing contactors. For very
small activation times (<0.3 ... 0.5 s), the motorwill be
{0,2 s} switched off during start-up process, which increases
significantly reversing contactors mechanical wear. With
frequent periods of very small activation times (restless
loop, small dead zone, clocking near to the target
value), we therefore recommend electronic reversing
contactor.
Variable speed actuators (RTS Compact Multi-Turn CM
and Smartcon
CSC FU): Without function
Fixed speed actuators (Smartcon CSC): This parameter
{2,0 s}
is only relevant when Step mode is enabled and when
approaching the target position (parameter gain smaller
than 100 %) and determines the period of a run / pause
cycle.
Smallest controllable position other than the end
0,0 – position CLOSED. The range 0% . . . a0 will be just passed
25,0% through. Use the parameter a0 to define the beginning
{2,0%} of the allowable control range of the valve (e.g., blind
spot for ball segment valves, etc.).
Largest controllable position other than the end position
75,0 –
OPEN. The area e0 . . . 100% is just passed through. Use
100,0%
the parameter e0 to define the end of the allowable
{98,0%}
control range of the valve.
Below this value, the end position CLOSED is controlled.
0,0 –
In the range 0% . . . a1 cannot be controlled (end
25,0%
position tolerance). The initial setpoint a1 is associated
{2,0%}
with a small hysteresis (1/4 of the deadband).
Above this value, the end position OPEN is controlled.
75,0 –
The range e1 . . . 100% cannot be controlled (end
100,0%
position tolerance). The final setpoint e1 is associated
{98,0%}
with a small hysteresis (1/4 of the deadband).
-10% - Calibration of zero for the input setpoint.
+10% 1% = 0.2mA
