poss. setting Notes / comments
P13.2 Positioner Begin (at 0%)
0 – 20.5 mA
{4.0 mA}
mA value of the setpoint for the CLOSED (0%)
position
P13.3 Positioner
End (at
100%)
0 – 20.5 mA
{20.0 mA}
mA value of the setpoint for the OPEN (100%)
position
P13.4 Positioner Dead band
0.1 – 10.0%
{1.0%}
Tolerance range for the control deviation (set point
position – actual position) where no adjustment
occurs. The deadband should not be set too low to
prevent actuator oscillation.
P13.5 Positioner Gain
1 – 100%
{100%}
The gain (gradient) affects the positioning close to
the target position. The smaller the gain selected
(e.g., 20%), the earlier the actuator starts reducing
its speed in case of speed variable actuators on
approaching the target position. In case of
actuators with fixed speed (reversing starters), the
speed reduction is done by pulsing (also see
params P13.9 and P13.10). This provided a better
positioning (smaller reachable deadband). A 100%
setting disables this gradient.
P13.6 Positioner
Live zero
detect.
Ignore
The setpoint monitoring (monitoring the setpoint to
below approximately 2 mA = loss of signal) is
disabled.
{Stop} Actuator stops on signal failure.
Open
On signal failure, actuator moves the OPEN
position.
Close
Actuator moves on signal failure to the CLOSED
position.
Emerg.pos.
On signal failure, the actuator moves the defined
emergency position (see parameter P13.7).
P13.7 Positioner
Emergency
pos.
0 – 100%
{50.0%}
Determination of the emergency position
(can also be set in menu P8.5)
P13.8 Positioner
Calib.
setpoint
-10% – +10%
Calibration value for the mA setpoint. Calibration
process: By applying 20 mA on the setpoint input,
this parameter is corrected until the readout
matches 20 mA.
P13.9 Positioner Min. Impuls {0.2 s}
Variable speed actuators (Actusmart 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 motor will
be switched off during start-up process, which
significantly increases wear on mechanical
reversing contactors. For frequent periods of very
small activation times (restless loop, small dead
zone, clocking near the target value), we therefore
recommend electronic reversing contactors.
P13.10 Positioner Period {2,0 s}
Variable speed actuators (Actusmart CM and
Smartcon CSC FU): Without function
Fixed speed actuators (Smartcon CSC): 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.
