ERROR + RANGE: Monitoring of error and range.
ERR+RANGE+INAC: Activation of all error monitoring functions.
16: ERROR TIME
Monitoring time to set the error messages.
This value (in seconds) is set to define the period of time within which the positioner must be in a steady state. The
corresponding response threshold is preset with parameter 17.
The error output ERR is set as soon as the position is out of the response threshold (error level) for a period longer than the
monitoring time (error time).
When set to „Auto“, this period is 10×the initialisation response time.This is automatically calculated during initialisation.
17: ERROR LEVEL
Response threshold for setting the error output ERR.
Specification in percent of the admissible variable of deviation to trigger an error message.
When set to „Auto“, the response threshold is equal to the slow speed range.
The slow speed range is automatically calculated during initialisation.
18: RANGE FUNCTN
Monitoring of the setpoint signal range
Specification whether a RANGE signal is to be triggered if 4 mA is not reached (monitoring of rupture of cable) or 20 mA
is exceeded (monitoring of short circuit).
21: MIN POSITION
Start of manipulated variable limiting (YA)
This function corresponds to a mechanical limitation of the closing movement.
See Fig. 6: Limitation of lifting-/closing movement.

INSTALLATION POSIMATIC
22: MAX POSITION
End of manipulated variable limiting (YE)
This function corresponds to a mechanical limitation of the lifting movement.
Parameters 21 and 22 limit the mechanical travel (from stop to stop) to the preset values.The
mechanical range of the actuator on the effective flow can thus be limited.
Fig. 6: Limitation of lifting and closing movement
i
24: SETP DIRECTN
Setpoint direction
Setting the setpoint direction specifies direction of action of the setpoint. It is mainly required for the split range mode and
for single acting actuators with „OPEN“safety position („control function 2“).
23: CLOSE TIGHT
Tight closing of manipulated variable
This function enables driving the valve at maximum actuator speed into its seat.The tight closing function can be activated
for one or both stop positions. CLOSE TIGHT is effective as soon as the setpoint is 0.5% above MIN POSITION or 0.5%
below MAX POSITION.
Since the setpoint range is set between 0% and 100% by 21 and 22, the threshold of activation of the tight closing
function in relation to the flow can be additionally adjusted downward with 21 and upward with 22.

25: SETP RAMP
Setpoint ramp
The setpoint ramp is activated in the manual and automatic mode.It limits the speed of the actuator in the event of a quick
rate-of-change of the setpoint.
In the setting SETP RAMP = auto the slower of the two positioning times calculated during initialisation is used for the
setpoint ramp.
26: SPLIT START
Setpoint for start of split range (Fig. 9: Split range operation)
27: SPLIT END
Setpoint for end of split range
Parameters 26 and 27 together with parameter 24 limit the effective setpoint range. This is a solution for split range
applications with
❑ rising / falling
❑ falling / rising
❑ falling / falling
❑ rising / rising
characteristic curves.

28: SETP FUNCTN
Setpoint function (Fig. 10: Characteristic valve curves)
This function enables the linearisation of non-linear characteristic curves of valves and the mapping of arbitrary flow
characteristics of linear characteristic curves of valves.
The device is provided with four characteristic curves:
❑ linear
❑ equal percentage 1 : 25
❑ equal percentage 1 : 50
❑ free (factory setting: 1 : 25 inverse)
A curve with 11 points can be entered at 30: when “free”is selected.

A flow value can be assigned to every setpoint at distance intervals of 10%.These points create a polygon with 10 straight
lines resulting in an image of the characteristic curve of the valve.
The setpoints can only be entered at 28. SETP FUNCTN = free.
Fig. 10: Characteristic valve curves
41: X-DISPLAY
Standardisation of manipulated variable
Limiting the manipulated variable via 21: MIN POSITION (YA) and 22: MAX POSITION (YE) creates two different scales
for display and position feedback (POSITION or FLOW).
POSITION is the mechanical position (0 to 100%) between the hard stops of initialisation and is not influenced byYA orYE.
FLOW is the standardisation of the display (0 to 100%) to the range betweenYA and YE and to the characteristic curve of
the valve selected with 28: SETP FUNCTN.The setpoint (0 to 100%) is then related to this FLOW range (0 to 100%).
X-DISPLAY can be changed to refer the display and the position feedback (x) to the flow (also if characteristic curves of
valves are used).
In this case, YE, YA and the characteristic curve of the valve is taken into account.
42: DEADBAND
Dead zone of the positioner
The dead zone specifies the maximum allowable deviation between the feedback value and the setpoint.
If DEADBAND = auto, the dead zone is adjusted to the requirements of the control loop during initialisation. The fixed
preset value for the dead zone is used for all other discrete settings.
Jumpy or nervous movements of the valve may occur if the setting for DEADBAND is too small.

Factory setting: PROP GAIN = 100 % corresponds to Kp = 1
44: DERIV TIME
Pre-act time
Setting of the pre-act time Tv (period of time in which a defined manipulated variable is reached more quickly than with a
P controller because of the D component).
DERIV TIME = 10 % ... 1000 % corresponds to Tv = 0.01s...1s
Factory setting: DERIV TIME = 100 % corresponds to Tv = 0.1s
Changing the factory setting of 43/44 may result in uncontrolled hunting of the valve.
