Characteristics
5.1.1.Assignment of outputs
Output contacts are used to send status signals (e.g. reaching the end positions,
selector switch position, faults...) as binary signals to the control room.
Status signals only have two states: active or inactive. Active means that the
conditions for the signal are fulfilled.
The output contacts (outputs DOUT 1 – 12) can be assigned to various signals.

AC 01.2/ACExC 01.2 Basic settings for commissioning
7.Basic settings for commissioning
Definition
Basic settings such as type of seating, torque and limit switching are required for
safe commissioning of the AUMATIC together with the actuator. Basic settings for
display, such as date and time or display formats, can be changed, if required.
7.1.Type of seating for end positions
●
Function
Selection of the type of seating (according to valve manuf acturer's specifications)
-Limit seating in end position
-Torque seating in end position
●
For end positions OPEN and CLOSE, the following can be set individually:
Limit seating
The controls switch off the actuator in the end positions (OPEN/CLOSED) set via
limit switching.
For end position seating via limit switching, you have to account for the overrun of
the actuator. Overrun [1] is the tra v el from s witching off until complete standstill.The
overrun depends on the inertia of both the actuator and the valve and the delay time
of the controls.
Figure 35: Limit seating
PTripping position
[1]Overrun
The controls switch off the actuator in the end positions via torque switching.
For this the torque switching has to be set to the tripping torque specified by the
valve manuf acturer .When reaching the end position, the torque increases within the
valve seat. As soon as the set tripping torque is reached, the controls automatically
switch off the actuator.
In this context, the limit seating is used to signal that the limit switching will trip shortly
before reaching the end position.

8.Application functions
Definition
Application functions are functions used to adapt the AC to special applications.This
includes device functions, communication functions and device information.
If they are enabled, these functions can be programmed by the user for his/her
specific task using parameters.
Each intermediate position can be set to a value between 0 and 100 % of the travel.
Customer settings M0041
Intermediate positions M0143
Pivot points M0160
Pivot point 1 M0249
Default values: 0.0 % for all 8 intermediate positions
Setting range: 0.0 % (CLOSED) to 100.0 % (OPEN) of the travel
InformationThe pivot points also apply to the <Operation profile> function.
8.1.2.Signal behaviour of intermediate positions: set
Reaching a pivot point (intermediate position) can be signalled:
●
via indication lights (LEDs) of the local controls or
●
via output contacts
Each pivot point (intermediate position) can be assigned a specific signal behaviour .

Actuator controls
AC 01.2/ACExC 01.2 Application functions
Figure 36: Signal behaviour (A to D) of the intermediate positions
Special characteristics of B, C and D
Behaviour of B and C:The signal is directly activated when reaching the set pivot
point (P).
Behaviour D: The signal is activated shortly before reaching the set pivot point (P).
The switch-on point is determined by pulse duration (+/– range around the pivot
point). Pulse dur ation depends on parameter Outer dead band M0148 and amounts
to 1.0 % of the travel for default setting.
InformationFor behaviours B and C, the signal might be omitted if, e.g when using a positioner,
pivot point (P) is not fully reached due to the dead band. In this case, behaviour D
can be selected as the dead band is considered.
8.1.3.Hysteresis for intermediate positions: set
The hysteresis determines the tripping point of the signal.
Example
Parameter Pivot point 6 M0253 is set to 50.0 % of the travel.

Parameter: Signal DIN 5 M0122 = OPEN/CLOSE
InformationThe logic for the digital inputs may be in verted. Depending on the parameter setting
(e.g.Coding DIN 6 M0128), the input is either High active or Low active. Default
setting is High active.
This function requires one of the following equipments within the actuator:
●
Electronic control unit with MWG (Non-Intrusive version)
●
Potentiometer
●
Electronic position transmitter EWG/RWG
Further conditions for the positioner operation mode:
●
Positioner enabled and activated.
●
Operation mode Remote (selector switch = position Remote control).
Characteristics
The positioner records setpoint position E1 and actual position value E2 for
comparison. Depending on the detected deviation, the actuator motor then runs in
direction OPEN or CLOSE.
●
Information
If the actuator is controlled via a setpoint (e.g. 0 – 20 mA), the status indication
S0003 on the display shows both the setpoint position E1 and the actual position
value E2.
●
If the status indication S0003 only shows the actual position value E2, OPEN
- CLOSE control is active: there is no setpoint control via the positioner. In this
case, you have to change-over to setpoint control first, refer to <Change-over
between OPEN - CLOSE control and setpoint control> chapter.

between setpoint and actual value for both directions and automatically adapts the
inner dead bands Xi and therefore switching point P2.
On the basis of the determined inner dead bands Xi and the set hysteresis
(parameters Positioner hyst. OPEN M0598 or Positioner hyst. CLOSE M0599), the
outer dead bands XT are automatically determined.
This reduces the error caused by the overrun after only a f e w oper ations and a high
positioning accuracy is achieved.

InformationIt must be ensured via the controls that the max. permissible number of starts of the
actuator is not exceeded.This can be achieved by setting the dead time to a sufficiently high value.
8.4.6.Hysteresis for positioner: set
The hysteresis determines the switching accuracy. It can be used to reduce the
number of starts for example.
This setting can only be made if the adaptive behaviour, parameter Adaptive

8.4.7.Closing fully/opening fully (end position tolerance for setpoint)
If the end positions cannot be reached due to inaccurate analogue setpoint signals
(0/4 mA or 20 mA), a tolerance for the setpoint within the end position range can be
set. If the toler ance is exceeded or not reached, the actuator continues the oper ation
until the full end position has been reached.This ensures that the actuator opens

8.4.12.Split Range operation
●
Requirements
Function
<Positioner> function must be enabled and activated:
In Split Range operation, a setpoint position E1 can be shared by up to three
positioners. A typical application example is a pipeline with a bypass.The actuator
mounted on the bypass reacts in the lower limit (e.g. 0 – 10 mA), the actuator on the
main valve in the upper limit (e.g. 10 – 20 mA). If the setpoint position is within the
setpoint range defined for the individual actuator, the actuator behaviour will be
identical to standard positioner operation. If the setpoint position is higher or lower
than the upper or the lower limit of the setpoint range of the respective actuator, the
actuator will run to positions OPEN or CLOSED.
The upper and lower limit of the respective actuator is defined via the analogue input.
(<Input range of setpoint position>)
In addition, the upper and lower limit of the total target value (valid for all actuators
grouped in a split range operation).

The following figure illustrates the function of the process controller:
The process controller [2] receives the process setpoint E7 and the actual process
value E4 (e.g. from a sensor). On the basis of both values, the process controller
calculates the position setpoint E1 for positioner [3]. In turn, the positioner [3]
compares this target setpoint with the actual position value E2 of the valv e and issues
the operation commands (OPEN - CLOSE) for the actuator.

For uncritical closed-loop applications allowing to accept continuous error variab les
in the event of failures, e.g. pressure, flow, filling level and temperature control.
PI controllers consist of a P fraction immediately reacting to a control deviation and
an I fraction for chronological integration of the input signal (error variable). Due to
the additional time constant of the I fraction, the output value takes more time to
reach the target status (i.e. inertia of control loop response) whereas positioning
accuracy increases at the same time (lower control deviation). P arameters f or setting

Compared to the PI controller, the PID controller has an additional D fraction
accounting for changes in the error variable (change rate).The D fraction quickly
reacts to changes, even to minor control deviations with large output values.

Setting values:
I/O interface
The process setpoint is defined via an analogue input (AIN 1 or AIN 2) of the I/O
interface.
Internal setpoint
The process setpoint is generated internally via actuator controls: parameters Internal
setpoint 1 M0749 / Internal setpoint 2 M0750
InformationTo use internal setpoint 2, a digital input must be configured accordingly.
In case of process setpoint signal loss, the actuator controls switch to the internal
setpoint 1. Parameter Internal setpoint 1 M0749
In case of process setpoint signal loss, the actuator controls switch to the internal

In case of process setpoint signal loss, the last available process setpoint will still
be used as setpoint.
8.5.5.Inverse operation
As standard, the valve is opened by the modulating actuator as soon as the actual
process value falls below the process setpoint. Depending on the process, it may,
however, be necessary that the valve closes as soon as the actual process value
falls below the process setpoint. In this case, the respectiv e par ameters are used to
set the process controller to inverse operation.

8.5.7.Setting procedure
The setting of the process controller largely depends on the area of controller
application. A PI controller suffices for most applications.
Procedure
1.Operate the controller as PT controller, i.e. set the parameters as follows:
-Proportional gain Kp = 1
-Reset time Ti = 1,000 s
-Rate time Td = 0
2.Double proportional gain Kp until the control loop starts to oscillate.
3.Reduce proportional gain Kp to 60 % of the set value.
4.Decrease reset time Ti until the error variable equals zero.
8.5.8.Proportional amplification Kp: set
In the event of an error variable, the P portion immediately (i.e. actively) changes
the position value proportionally to the error variable.
If a small error variable already requires a major valve position adjustment, the
proportional gain Kp must be increased.
InformationIf the reaction is too extreme (ov ershoot), the value must be reduced. If the reaction
is too weak, the value must be increased.

8.7.By-pass function
— Option —
Application
Function
The by-pass function is used, e.g. for district heating pipelines. Under high pipeline
pressure, the gate valve of the main valve cannot be used, pressure compensation
via by-pass valve is therefore required.
Two MOVs – one main valve and a by-pass valve – are linked via enable signals
Bypass Sync In and By-pass Sync Out. Operation commands can only be e xecuted
if one of the two actuators sends the enable signal to the other. Release depends
on the end position.This ensures that only the following operation commands may
be executed:
●
The main valve can only be operated in directions OPEN or CLOSE if the bypass valve is in end position OPEN.
●
The by-pass valve can only be operated in direction CLOSE if the main valve
is in end position CLOSED. However, it can always be operated in direction
OPEN.

EMERGENCY behaviour
Example
The emergency behaviour of the by-pass function has the same characteristics as
the <EMERGENCY behaviour> function with the following differences:
In an EMERGENCY situation, both controls receive the EMERGENCY signal at the
same time.This signal starts the EMERGENCY operation specially defined for the
by-pass function. (Parameter EMCY operation M0204 is therefore not available in
the <EMERGENCY behaviour> function).
EMERGENCY operation procedure
1.By-pass valve is opened first.
2.Once the by-pass valve is fully opened, the main valve is closed.
3.Once the main valve is fully closed, the by-pass valve is fully opened.

8.8.Lift Plug Valve (LPV)
— Option —
Application
A "Lift Plug Valve" is a special valve whose closing element must first be lifted out
of its seat or locking position before being rotated for opening or closing the valve.
Locking of the valve and/or pressure relief prior to rotation of the closing element
can thus be implemented. Once the end position has been reached, the closing
element has to be lowered again. Such valves are in particular used for significant
pressure differences (pressure relief) and safety-related systems (locking).
Requirements
Function
●
●
Due to the special design of the LPV valves, they can only be operated in
OPEN-CLOSE duty (no modulating duty). For this type of duty, two actuators are
required which are operated as a master-slave-system with master actuator (rotary
movement) and slave actuator (stroke movement). However, only one actuator or
actuator controls is "visible" at the DCS, i.e. the sla ve actuator is completely controlled
and monitored by the master actuator. Communication between master and slave
actuator is performed via the additional <Parallel interface> I/O Interface 2.
Two actuator controls and actuators are required, one of them is considered
as master actuator (MA), the other one as slave actuator (SA).
The actuator controls of the master actuator require an additional <Parallel interface > I/O Interface 2.

Actuator controls
AC 01.2/ACExC 01.2 Application functions
Figure 46: Schematic representation of the function of a Lift Plug Valve
The master actuator may generally only be operated in direction OPEN or CLOSE
if the slave actuator is fully opened.This is ensured by a signal of the slave actuator
to the digital LPV Sync In input of the master actuator as soon as the slave actuator
has reached end position OPEN.The slave actuator may generally only be operated
in direction CLOSE if the master actuator is in end position OPEN or CLOSED .This
is ensured by a corresponding signal of the master actuator to the digital LPV SyncIn input of the slave actuator . However, it can alw a ys be operated in direction OPEN.
If the master actuator receives an operation command for direction OPEN or CLOSE,
it will first send a command to the slave actuator for operation in direction OPEN.
Once the slave actuator has reached end position OPEN and sends the feedback
signal, the master actuator executes the requested operation command itself. After
reaching the desired end position, it will request the slave actuator to run to end
position CLOSED.

8.9.Multiport valve function (operation to position)
— Option —
Application
Characteristics
Information
For valv es not equipped with end stops (multi-turn) and with up to 12 ports (multiport
valves)
The multiport valve function allows to directly access a valv e port (position) of a valve
equipped with up to 12 ports without stopping at any other port (position). Example:
Operation from position 2 to 4 without stopping at position 3.
In the operation mode Local, the set position are approached as directly as possible,
i.e. the direction of rotation (clockwise or counterclockwise) depends on the current
position of the valve.
In operation mode Remote, up to 10 positions can either be approached with a
defined direction of rotation (counterclockwise or clockwise) or as directly as possible .
The actuator then operates the valve with the defined direction of rotation or as
directly as possible to the defined valve attachment, irrespective of the actuator
position.
●
The multiport valve function is only permissible in combination with an AUMA
actuator and an AUMA gearbox.
●
The output speed at the output drive (of the gearbox) or the valve should not
exceed approx. 0.3 rpm; otherwise positioning accuracy will decrease.
Procedure for commissioning a multiport valve
1.Set/check multiport valve parameters:
(generally, they are set in the factory prior to delivery)
-Actuator type
-Gear reduction ratio
-Number of ports (positions)
-Configuration of digital inputs
2.Define/check positions (of valve ports).
3.Set/check signal behaviour of positions.
4.Set home port (zero position).
5.Approach positions.
6.If required, perform/correct multiport valve parameter settings like inertia, dead

Unexpected starting of actuator!
When using automatic deblocking with le vel-controlled operation command ev aluation,
unexpected starting of actuator into the wrong direction might occur when trying to
eliminate a double-sided torque fault (torque faults in directions OPEN and CLOSE
are present at the same time).
→
Use automatic deblocking only in combination with edge controlled operation
command evaluation (parameter Com. eval. REMOTE M1709).
Characteristics
In case of torque switch tripping in intermediate position (i.e. prior to reaching the
end position), the actuator automatically attempts to reach the end position by
operation into the opposite direction and executing the actual operation command
once again.

AC 01.2/ACExC 01.2 Failure functions
9.Failure functions
Definition
9.1.Reversing prevention time
Application
Characteristics
Failure functions are started by certain events and lead to a defined action of the
controls or the actuator. A failure operation can be started by a manual action (e.g.
pressing an EMERGENCY stop button). In general, a failure operation is automatically
started by a fault signal from a monitoring function (e.g. loss of signal).
Prevention of impermissible operation states such as: Operation command in direction
OPEN, actuator still runs in direction CLOSE due to the delay time.
The reversing pre vention time (off-time between tw o operation commands in opposite
direction) prevents a restart for a defined interval once the motor has switched off.
Parameters and instructions for setting

9.2.Failure behaviour on loss of signal
Characteristics
The failure behaviour can be used to define A C reaction to loss of signal or a defectiv e
signal.
Only in operation mode Remote will the failure behaviour react to a signal loss. In
operation modes Local or Off, there will be no reaction.

The <Failure behaviour> is only initiated if the monitored signal fails (falling edge).
This setting ensures that if the signal is missing, the actuator will not start when
switching on (Good signal first).
The <Failure behaviour> is immediately initiated if the monitored signal is missing
(is not present).
For the setting Immediately active:
The actuator can start immediately when switching on!
Risk of personal injuries or damage to the valve.
→
Ensure that the signal set under parameter Failure beh. source M0385 is present
when switching on.

Actuator controls
Failure functions AC 01.2/ACExC 01.2
Default value: I/O interface
Setting values:
I/O interface
The failure behaviour is initiated in case of loss of setpoints.
The monitoring depends on the preset setpoint range, e.g.:
●
Setpoint = 4 – 20 mA, E1 lower than 3.7 mA = loss of signal
●
Setpoint = 10 – 20 mA, E1 lower than 9.7 mA = loss of signal
For a setpoint range of 0 – 20 mA , monitoring is not possible.
9.2.3.Failure operation (reaction of the actuator) on loss of signal

The actuator runs to the predetermined position. Conditions:
●
The function <Positioner> is activated.
●
Parameter Failure beh. source M0385 is set to I/O interface
The actuator executes the last operation command before it is stopped.
If the last operation command was a setpoint definition via analogue input (AIN 1/AIN
2), the lower limit of the setpoint position is used (parameter Low limit AIN 1/Lowlimit AIN 2).The actuator is operated to the defined end position, usually end position
CLOSED.
Behaviour depending on the selector switch position:
Once the failure operation is triggered, the defined position is approached. If the
actuator is then moved to another position (e.g. by manual operation), it will try to
perform the set failure operation while the selector switch is in position Remote
control (REMOTE).
InformationTo prevent a new approach to the failure position during manual operation, the se-
lector switch must be set to position Local control (LOCAL) or 0 (OFF) prior to
operating the handwheel.

9.3.EMERGENCY behaviour
Application
The EMERGENCY behaviour can be used to determine the actuator behaviour in
an emergency.
●
Characteristics
The function <EMERGENCY behaviour> is initiated by the EMERGENCY signal.
●
The actuator performs a defined EMERGENCY operation. For example, the
actuator moves to a predefined EMERGENCY position (i.e. end position OPEN
or end position CLOSED).
●
As long as the EMERGENCY signal is present, the actuator does not respond
to any other operation commands (EMERGENCY signal has top priority).
●
After initiating the EMERGENCY behaviour, binary operation commands (via
digital inputs) may have to be sent again.
For the function <EMERGENCY behaviour>, a digital input for the signal
EMERGENCY has to be available and configured.
Configuration of digital input

InformationThe logic for the digital inputs may be in verted. Depending on the parameter setting
(e.g.Coding DIN 4 M0126), the input is either High active or Low active. For safety
reasons, the EMERGENCY signal input is generally set to Low active.

immediately once the AC is switched on and no EMERGENCY signal is present.
The <EMERGENCY behaviour> is initiated by a low le vel at the EMERGENCY signal.
For this setting, the EMERGENCY has to have a high level before switching on the
AC; otherwise <EMERGENCY behaviour> is initiated immediately after switching

9.9.Partial Valve Stroke Test (PVST)
— Option —
Characteristics
The Partial Valve Stroke Test (PVST) is used to check the function of both actuator
and actuator controls. During this test, the function of the valve is tested by means
of partial opening or closing within a defined period of time without interrupting the
process. After successful testing, actuator controls operate the actuator to its initial
position.
If the test was not successful, actuator controls will generate the following signals:
PVST fault PVST abort For monitoring the PVST, these signals must be evaluated
by a PLC.
●
Requirements
Position transmitter in the actuator
●
Function <Positioner> activated.
●
If the actuator is in safe state (caused by the f ailure beha viour), the test will not
be performed.
●
The test can only be performed during OPEN - CLOSE control. For setpoint
control (modulating duty), a test cannot be performed.
For the change-ov er, a digital input for the signal Execute PVST has to be available
and configured.
InformationThe logic for the digital inputs may be in verted. Depending on the parameter setting
(e.g.Coding DIN 4 M0126), the input is either High active or Low active. For safety
reasons, the Execute PVST signal input is generally set to Low active.

10.Monitoring functions
Definition
10.1.Torque monitoring
The monitoring functions signal a warning or a fault as soon as a certain value is
outside the permissible range. Faults generally cause an actuator shutdown.
Torque monitoring has the following functions:
●
Valve overload protection against excessive torques (leads to switching off)
●
Torque warning before overload protection tripping (only in combination with
electronic control unit in the actuator)
Overload protection
Once the overload protection trips (torque exceeds set tripping torque), the actuator
is stopped.
The controls generate a fault indication if:
●
the excessive torque occurs between end positions
●
the excessive torque occurs in the end positions and limit seating is set.
The fault indication is shown in the display
●
Status indications: S0007 Fault or S0011 Failure
-
Details: Torque fault CLOSE or Torque fault OPEN
The fault has to be acknowledged before the operation can be resumed:
1.either by an operation command in the opposite direction.
-
For Torque fault CLOSE : Operation command in direction OPEN
-
For Torque fault OPEN : Operation command in direction CLOSE
Requirements
2.or, in case the torque applied is lower than the preset tripping torque after trip-
ping:
-via the RESET push button in selector switch position Local control
(LOCAL).
Depending on the version, tripping torques for overload protection are either set via
switches in the actuator or via software parameters in the controls . For the settings,
refer to <Torque switching> chapter.
Torque warning
Actuator with electronic control unit (MWG).
The torque warning can be used e.g. for self-monitoring or for anticipating
maintenance requirements.

Setting range: 0.0 ... 5.0 s seconds
InformationIf torque by-pass is activated, the interval should be longer than the set time period
for reversing prevention time to ensure torque by-pass will also be effective in the
event of reversal of operation.
In order to protect against overheating and impermissibly high temperatures at the
actuator, PTC thermistors or thermoswitches are embedded in the motor winding.
The thermoswitch is tripped as soon as the max. permissible winding temperature
has been reached.
The actuator is switched off and the following signals are given:
●
LED 3 (motor protection trippped) on the local controls is illuminated.
●
Status indication: S0007 Fault or S0011 Failure
-
Details: Thermal fault
The motor has to cool down before the operation can be resumed.
Depending on the parameter setting (motor protection behaviour), the fault signal is
either automatically reset or the fault signal has to be acknowledged manually.
Manual acknowledgement can be made:
●
in selector switch position Local control (LOCAL) via push button RESET.
●
in selector switch position Remote control (REMO TE) via a digital (I/O interface)
with the RESET command if a digital input is configured for signal.
In addition, the AC cyclically (once per day) checks the motor protection monitoring
for its proper function. If this check fails, the controls generate the fault indication:

Once the motor has cooled down, the fault has to be ackno wledged (reset) manually
as described above.
If required the thermal overload relay has to be reset manually.To this end, remove
the cover on the back of actuator controls and oper ate the reset button on the thermal
overload relay.
10.3.Type of duty monitoring (motor starts and running time)
This function monitors the permissible type of duty (e.g. S2 - 15 min) of the actuator .
For this, controls monitor possible excess of
●
permissible motor starts (cycles) per hour
●
permissible running time (on-time) per hour
If any of these values has been e xceeded, the actuator will howe v er not be stopped,
but the following warning signals are issued.
●
Status indications: S0005 or S0008
-
Details: Wrn on time starts
●
Status indications: S0005 or S0008
-
Details: Wrn on time running
The warning signals will automatically be cleared if the permissible motor starts per
second or the permissible running time per hour are no longer reached.
The operational info logger records the number of excesses (warnings) as well as
the number of motor starts and motor running times.
Example:
Asset Management M1231
Operational info M0177
Operational info M0188
On time warning 1 M0325 contains total number of all on time warnings.
On time warning 2 M0326 contains maximum duration of on time warning
Due to excess of defined starts/h or defined running time/h, the AC issues in total 4
on time warnings: two for 5 min, once for 10 min, once for 17 min. Afterwards the
operating data counters contain the following values:
On time warning 1 M0325 = 37 min = total of all periods (5+5+10+17 min)
On time warning 2 M0326 = 17 min = longest period
