6. Operation

Different operation modes (states) are available.The current operation mode is
indicated in the first line of the display:

Figure 34: Example: Operation mode Off

This chapter describes the characteristics of the different operation modes; the
respective functions are described in separate chapters.

6.1. Operation mode Off

The selector switch is in position 0 (OFF).

●

Characteristics

The indication in the top row of the display shows:Off

●

Electric operation is not possible (not even EMERGENCY operation).

●

The controls remain fully operative as far as signalling is concerned (controls’
power supply is maintained).

●

Push buttons C can be used for menu navigation via the display.

6.2. Operation mode Local

Selector switch is in position Local control (LOCAL).

●

Characteristics

The indication in the top row of the display shows:Local

●

In motor operation, the actuator can be controlled locally via the push buttons

(OPEN), STOP, (CLOSE).

●

Faults and warnings without automatic reset can be confirmed with the push
button RESET.

6.2.1. Push-to-run operation or self-retaining Local

Parameter Self-retaining Local M0076 determines the actuator operation behaviour
to operation commands via push buttons on local controls.

OPEN

CLOSE

Push-to-run operation activated, self-retaining off:
Actuator only runs in directions OPEN or CLOSE while an operation command is

being received.The actuator stops if the operation command is cancelled.
In direction OPEN = self-retaining (in direction CLOSE push-to-run operation):
After an operation command in direction OPEN, the actuator continues to run, even

if the operation command is cancelled (self-retaining).The actuator is either stopped
by the STOP command or if end position OPEN or an intermediate position OPEN
has been reached.

In direction CLOSE = self-retaining (in direction OPEN push-to-run operation):

32

Actuator controls
ACV 01.2/ACVExC 01.2 Operation

After an operation command in direction CLOSE, the actuator continues to run, even
if the operation command is cancelled (self-retaining).The actuator is either stopped
by the CLOSE command or if end position CLOSED or an intermediate position
CLOSED has been reached.

OPEN and CLOSE

In directions OPEN and CLOSE = self-retaining:
After an operation command, the actuator continues to run in directions OPEN or

CLOSE, even if the operation command is cancelled (self-retaining).The actuator
is either stopped by the STOP command or if an end position or intermediate position
has been reached.

Direct reversal of operation is not possib le. Operation commands in directions OPEN
or CLOSE must be stopped first by STOP command. Only then is an operation
command into the opposite direction allowed.

Remote II M0101:

Off (push-to-run op.)

Push-to-run operation activated, self-retaining off:
Actuator only runs in directions OPEN or CLOSE while an operation command is

being received.The actuator stops if the operation command is cancelled.

OPEN

In direction OPEN = self-retaining (in direction CLOSE push-to-run operation):
After an operation command in direction OPEN, the actuator continues to run, even

if the operation command is cancelled (self-retaining).The actuator is either stopped
by the STOP command or if end position OPEN or an intermediate position OPEN
has been reached.

CLOSE

In direction CLOSE = self-retaining (in direction OPEN push-to-run operation):
After an operation command in direction CLOSE, the actuator continues to run, even

if the operation command is cancelled (self-retaining).The actuator is either stopped
by the CLOSE command or if end position CLOSED or an intermediate position
CLOSED has been reached.

OPEN and CLOSE

In directions OPEN and CLOSE = self-retaining:
After an operation command, the actuator continues to run in directions OPEN or

CLOSE, even if the operation command is cancelled (self-retaining).The actuator
is either stopped by the STOP command or if an end position or intermediate position
has been reached.

Direct reversal of operation is not possib le. Operation commands in directions OPEN
or CLOSE must be stopped first by the STOP command.. Only then is an operation
command into the opposite direction allowed.

OPEN & CL w/o STOP

In directions OPEN and CLOSE = self-retaining without stop:
Direct reversal of the operation direction without STOP command is possible.
Direct reversal of operation is also possible without the STOP command. However,

operation can be stopped at any time by the STOP command.

6.4. Operation mode EMERGENCY

See also: Failure function <EMERGENCY behaviour>

●

Characteristics

The indication in the top row of the display shows:EMERGENCY

●

The operation mode EMERGENCY is initiated by the EMERGENCY signal.

●

The actuator performs an 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).

The actuator can start immediately when switching on!

Risk of personal injuries or damage to the valve.

→

Ensure that the EMERGENCY signal is present when switching on.

→

Should the actuator start unexpectedly: Immediately set selector s witch to pos­ition 0 (OFF).

7. Basic settings for commissioning

Definition

Basic settings such as type of seating, torque and limit switching are required for
safe commissioning of the actuator controls 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

P Tripping 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 actuator controls 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.

8.1. Speed functions

SAV/SARV actuators can be controlled via ACV actuator controls using individual
speed setpoints for operations in direction OPEN or CLOSE.This chapter describes
control in standard operation (operation modes Local and Remote). Settings and
behaviour in e.g. emergencies (operation mode EMERGENCY) as well as failure
behaviour (on loss of signal) are described together with the respective safety
functions.

8.1.1. Speed source for local operation and remote operation

The actuator speed for local operation (via local controls) and remote operation can
be provided from different speed sources.The speed can be set individually for each
operation direction (OPEN/CLOSE).The input signal of the respective speed source
can either be programmed as constant or variable speed value.

●

as constant, internal value (programmable speed)

●

as variable, external value (via analogue signal)

As a general rule, the speed source has already been set in the factory according
to the indications on the order.

parameters Speed internal1 M1930 – Speed internal 4 M1933.

Speed selection via two external signals. F or this setting, changing between the f our
internally programmed, constant speeds (Internal 1 – Internal 4) is possible.

Two digital inputs have to be configured as control signals for speed selection.
The actuator speed is specified/modified externally via an analogue value (e.g. 0 –

20 mA).
An analogue input has to be defined as speed source.

Configuration of digital inputs for external speed selection

For setting of parameter Sp. source... = 2 DigIn: "Internal (1-4)" (external speed

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.

Information

For 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.

8.2.3. Hysteresis for intermediate positions: set

(e.g.Coding DIN 6 M0128), the input is either High active or Low active. Default
setting is High active.

8.5. Positioner (operation mode Remote SETPOINT) Conditions

This function requires one of the following equipments within the actuator:

●

Electronic control unit (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 setpoint position E1 and actual position v alue
E2.

●

If the status indication S0003 only shows actual position value E2, OPEN­CLOSE control is active and there is no setpoint control via the positioner. In
this case, you have to change-over to setpoint control first, refer to <Change­over between OPEN-CLOSE control and setpoint control> chapter.

Adaptive I

Adaptive behaviour for precise positioning (high positioning accuracy).
Due to the inertia of actuator and valve, the valv e position changes only slightly after

switching off the actuator (overrun).The positioner determines the resulting error
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 Posit. hyst. OPEN M0598 or Posit. 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.

oscillation.

8.5.3. Overrun (inner dead band): set manually

The inner dead band determines the switch-off point of the actuator and therefore
influences the overrun.

The inner dead band may be set individually for the directions OPEN and CLOSE.
Manual setting is only possible if the adaptive behaviour, parameter Adaptive

behaviour M0147 is switched off.

8.5.4. Max. error variable (outer dead band): set manually

The outer dead band determines the switching-on point of the actuator.
The motor starts if the actual value (input signal E2) or a change in nominal value is

higher than the max. error variable determined by the outer dead band.
Manual setting is only possible if the adaptive behaviour, parameter Adaptive

behaviour M0147 switched off.

●

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.

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

setpoint 1. Parameter Internal setpoint 1 M0749

In case of process setpoint signal loss, the actuator controls switch to the internal
setpoint 2. Parameter Internal setpoint 2 M0750

In case of process setpoint signal loss, failure behaviour procedure is activated.
Parameter Failure behaviour M0378

In case of process setpoint signal loss, the last available process setpoint will still
be used as setpoint.

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.

8.6.7. 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 PI 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.

8.6.8. 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.

Information

8.6.9. Reset time Ti: set

Information

If the reaction is too extreme (ov ershoot), the value must be reduced. If the reaction
is too weak, the value must be increased.

Customer settings M0041

Proport. gain Kp M0744

Default value: 1.0
Setting range: 0.1 ... 10.0

The reset time determines the I portion of the controller.The more inert a system,
the higher this value should be set.

●

Increase Ti in case of propensity for oscillation.

●

Decrease Ti if the reactions are excessively delayed.

●

Starting value for fast processes (e.g. pressure): 10 s

Information

62

The rate time determines the D portion of the controller.Typically, no setting is
required here (= 0), since actuator and valve – due to the operating time – cannot
react abruptly to a sudden occurrence of an error variable.

8.8. By-pass function

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 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.

For actuator controls in SIL version, we DISADVISE using the automatic deblocking
function.

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

8.9.1. Automatic deblocking function: activate

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.

The torque fault signal is suppressed during automatic deblocking. Should torque
switching trip again once automatic deblocking is complete , the actuator is s witched
off and actuator controls signal a torque fault.

8.10. Synchronous link Application

Function

Synchronous link means synchronous electrical operation of two actuators (master
actuator/slave actuator) without mechanical link.The synchronous link function can
be used to operate two gate valves within a weir, for example.

Two MOVs – one main valve and a secondary valve – are linked via four signals.
End position OPEN/CLOSED , selector switch Remote, de viation too high and f ailure
as well as possible speed correction for synchronous operation are signalled or
controlled via the main valve.

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.

Default value: I/O interface
Setting values:

I/O interface

The failure behaviour is initiated in case of setpoint loss (setpoint position, process
setpoint, actual process value).

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

●

Information

For a setpoint range of 0 – 20 mA , monitoring is not possible.

●

Actuator controls will only respond to a setpoint signal loss, if a signal is present
at the MODE input, i.e. actuator controls are in operation mode Remote SET­POINT (setpoint control).

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 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/Low
limit 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).

To prevent a new approach to the failure position during manual operation, the se­lector switch must be set to position Local control (LOCAL) or 0 (OFF) prior to
operating the handwheel.

9.3. EMERGENCY behaviour Application

Characteristics

Condition

The EMERGENCY behaviour can be used to determine the actuator behaviour in
an emergency.

●

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.

●

Analogue operation commands (e.g. 0/4 – 20 mA) are immediately executed
again.

For the function <EMERGENCY behaviour>, a digital input for the signal
EMERGENCY has to be available and configured.

Immediately active

The <EMERGENCY behaviour> is initiated as soon as the EMERGENCY signal
changes from high to low. Example: for binary EMERGENCY input of +24 V DC to
0 V.This prevents the <EMERGENCY behaviour> from being initiated immediately
once the actuator controls are 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 signal has to have a high level before switching
on the actuator controls; otherwise <EMERGENCY beha viour> is initiated immediately
after switching on.

Example

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.

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 trip­ping:

- 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.

10.2. Motor protection monitoring (thermal monitoring)

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: S0007Fault 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 RESET signal.

In addition, the actuator controls cyclically (once per day) check the motor protection
monitoring for its proper function. If this check fails, the controls generate the fault
indication: IE mot. prot. monitor

Conditions:

Characteristics

Information

Information

Phase failure monitoring is only valid f or connections to 3-phase AC po wer supplies.
For versions with 1-phase AC or DC, phase failure monitoring is not possible.

The actuator controls monitor phase L2 If phase L2 is missing for a certain time
interval, the actuator controls still can send and receive signals and generate a fault
indication. Since the actuator controls are supplied via phases L1 and L3, the two
phases cannot be monitored. In case L1 or L3 fails, the actuator controls are
inoperable and the actuator stops.

In case of phase L2 loss during motor operation, this does not necessarily lead to
an immediate standstill of the actuator.The reason is that the rotating motor generates
the missing phase itself.This leads, however, to a reduction of the motor output
torque. If the applied torque is sufficient for valve operation, the missing phase L2
is only detected when switching off (e.g. in an end position) and the Phase fault fault
signal is generated as a consequence.

12.1. Direction of rotation Characteristics

Information

This function allows changing the direction of rotation for actuator with 3-phase AC
motors.

The direction of rotation indicates the direction into which the drive shaft rotates
around its own axis.The view is on the top of the actuator. Distinction is made
between clockwise and counterclockwise rotation.

●

When changing from clockwise closing to counterclockwise closing or vice
versa, only the direction of rotation of the motor is changed.The change-over
requires further action:

- The wiring diagram designation is marked on the actuator controls name
plate. In case of a change, a ne w name plate with the ne w wiring diagram
number has to be requested from AUMA.

- The wiring diagram number is stored in the electronic device ID (parameter
Wiring diagram actuator M0060).The ID has to be adapted to the new
designation once conversion is complete.

- The actuator mounted to the controls must be configured for the set direc­tion of rotation. Subsequent con version from cloc kwise closing to counter­clockwise closing is possible using an AUMA conversion kit.

Parameters and instructions for setting

Setting the direction of rotation using parameters is only possible for actuators with
electronic control unit/MWG (Non-intrusive version).

Valve damage due to incorrect direction of rotation!

For 3-phase AC motors, the rotation direction of the actuator must match the
rotation direction of the valve.
