4 OPERATION
X-LIMIT (factory setting: XMIN = 0%, XMAX = 100%): Stroke limitation.
This additional function enables the (physical) stroke to be limited to a given MIN and MAX percentage
value (Fig. 36). In the AUTOMATIC mode the stroke range of the limited stroke is then set to equal
100%. In the MANUAL mode, on the other hand, the physical stroke is displayed. (It should therefore
be noted that a limited stroke will be displayed differently in the AUTOMATIC and MANUAL modes).

Setting range:
XMIN: 0 ... 50 % of the total stroke,
XMAX: 50 ... 100 % of the total stroke.
The minimum distance between XMIN and XMAX is 50%.
X-TIME (factory setting: OPN FAST, CLS FAST): Setting speed limitation
Options:
OPN FAST (open fast): Opening of the control valve happens with maximal control speed.
OPN SLOW (open slow): The maximum setting speed of the control valve is limited during
opening.
CLS FAST (close fast): Closing of the control valve happens with maximal control speed.
CLS SLOW (close slow): The maximum setting speed is limited when the control valve is
closing.
PCONTRL (process control): Process controller configuration
SETPOINT (factory setting: EXTERNAL): Preset desired value.
INTERN: Desired value can be input using the arrow keys (see § 4.4.2).
EXTERN: Desired value is preset via the standard signal input.
PARAM: Set parameters for process controller (PID controller)
KP: (Proportional correction value or amplification)
Range of settings: 0...99.99 (factory setting: 1.00)
TN: (reset time)
Range of settings: 0.5...999.9 (factory setting: 999.9)
