P13.8
Positioner
Calibration
setpoint
-10% - +10%
Calibration value for the mA setpoint. Calibration
process: By applying 20mA on the setpoint input, this
parameter is corrected until the readout matches 20mA.
P13.9
Positioner
Minimum
Impulse
{0.2 s}
Minimum activation time of the reversing contactors.
For very small activation times (<0.3 to 0.5s), the motor
will be 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.
P13.10 Positioner
Period
{2.0 s}
This parameter 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.
P13.11 Positioner
Begin
position (a0)
0.0 – 25.0%
{2.0%}
Smallest controllable position other than the end
position CLOSED. The range 0% to 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 Position
(e0)
75.0 – 100.0%
{98.0%}
Largest controllable position other than the end
position OPEN. The area e0 to 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
Setpoint (a1)
0.0 – 25.0%
{2.0%}
Below this value, the end position CLOSED is
controlled. In the range 0% to 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 Setpoint
(e1)
75.0 – 100.0%
{98.0%}
Above this value, the end position OPEN is
controlled. The range e1 to 100% cannot be controlled
(end position tolerance). The final setpoint e1 is
associated with a small hysteresis (1/4 of the deadband).
P13.15 Positioner
Calib.
setpoint
offset
-10% - +10%
Calibration of zero for the input setpoint. 1% = 0.2 mA.
