1. Safety instructions

1.1 Range of application AUMA actuators are designed for the operation of industrial valves,

e.g. globe valves, gate valves, butterfly valves and ball valves.
For other applications, please consult us. The manufacturer is not liable for
any possible damage resulting from use in other than the designated appli

­cations. Such risk lies entirely with the user.
Observance of these operation instructions is considered as part of the
controls’ designated use.

1.2 Commissioning
(electrical connection)

During electrical operation, certain parts inevitably carry lethal voltages.
Work on the electrical system or equipment must only be carried out by a
skilled electrician himself or by specially instructed personnel under the
control and supervision of such an electrician and in accordance with the
applicable electrical engineering rules.

1.3 Maintenance The maintenance instructions must be strictly observed, otherwise a safe

operation of the multi-turn actuator/ the controls is no longer guaranteed.

1.4 Warnings and notes Non-observance of the warnings and notes may lead to serious injuries or

damage. Qualified personnel must be thoroughly familiar with all warnings
and notes in these operation instructions.
Correct transport, proper storage, mounting and installation, as well as
careful commissioning are essential to ensure a trouble-free and safe oper­ation.
The following references draw special attention to safety-relevant proce­dures in these operation instructions. Each is marked by the appropriate
pictograph.

This pictograph means: Note!

“Note” marks activities or procedures which have major influence on the
correct operation. Non-observance of these notes may lead to consequen­tial damage.

This pictograph means: Electrostatically endangered parts!

If this pictograph is attached to a printed circuit board, it contains parts
which may be damaged or destroyed by electrostatic discharges. If the
boards need to be touched during setting, measurement, or for exchange, it
must be assured that immediately before a discharge through contact with
an earthed metallic surface (e.g. the housing) has taken place.

This pictograph means: Warning!

“Warning” marks activities or procedures which, if not carried out correctly,
can affect the safety of persons or material.

2. Short description AUMA actuators have a modular design. Motor and gearing are mounted in

a common housing.

4. General information about Modbus

For the exchange of information among automation systems and between
automation systems and the connected decentral field devices, serial
fieldbuses are mainly used today as the communication system. Thousands
of applications have proved impressively that cost savings of up to 40 % in
wiring, commissioning, and maintenance are achieved by using fieldbus
technology. Just two wires are needed to transmit all relevant information for
the field devices, such as input and output signals, parameters, and diag­nostics data. While in the past the fieldbuses used were often manufacturer
specific and incompatible with other bus systems, the systems employed
today are almost exclusively open and standardized. This means that the
user is independent of individual suppliers and can choose the best product
at the most competitive price.
Modbus is an open international fieldbus system which is also used
successfully throughout the world. The application range includes automa­tion in the areas of manufacturing, processing, and building.
These operation instructions cannot provide a general introduction into
Modbus. For this, please refer to the literature references in appendix C
(page 57).

4.1 Basic characteristics Modbus defines the functional features of a serial fieldbus system with

which distributed digital automation devices can be interconnected. Modbus
distinguishes between master and slave devices.

Master devices control the data traffic on the Bus. A master is allowed to
send messages without an external request.

Slave devices such as AUMA Modbus actuators are peripheral devices.
Typical slave devices are input/ output devices, valves, actuators, and
measuring transmitters. They do not have bus access, i.e. they may only ,at
the request of a master, transmit messages to that master.

Actuator controls AUMA MATIC AM/ AMExB/ AMExC

Operation instructions Modbus

4.2 Modbus Basic functions Modbus uses a master-slave technique in which only the master can initiate

a transaction. The slaves respond by supplying the requested data in a reply
or by executing the action requested in the query.

The Modbus telegram from the master contains the slave address, a func

­tion code defining the requested action, a data field, and a CRC field. The
Modbus slaves’ response message contains fields confirming the requested
action and possibly the requested data and also a CRC field.
If an error occurs during reception of the telegram or the slave is unable to
perform the requested action, the slave will generate an error telegram and
send it as response to the master.

4.3 Transfer mode

.

RS-485 twisted pair cable or fibre optic cable.

.

AUMA actuators support baud rates up to 38.4 kBit/s

4.4 Bus access

.

Master-slave technique.

.

Mono-master system.

.

Master and slave devices: max. 127 devices at one bus
(the AUMA MATIC supports slave addresses from 1 to 127), without
repeater max. 32 devices.

4.5 Communication

.

Master-slave data exchange via query-response cycle (Polling procedure).

.

Modbus RTU protocol.

4.6 Protection functions

.

Parity check for each telegram byte

.

CRC check for each telegram

.

Watchdog for AUMA actuators with adjustable failure behaviour.

.

Query-response cycle monitoring with configurable timer interval at the
master.

4.7 Modbus RTU mode Data format for a byte.

Coding system:

.

8 bit binary, hexadecimal 0-9, A-F

.

2 hexadecimal characters contained in each 8 bit field of the telegram

Bits per byte:

.

1 start bit

.

8 data bits; least significant bit sent first

.

1 bit for even/ odd parity, no bit for no parity

.

1 stop bit if parity is used, 2 stop bits if no parity is used.

6. Design AUMA MATIC Modbus

The AUMA MATIC Modbus by AUMA represents the ideal controls for
connecting multi-turn actuators of the SA range and part-turn actuators of
the SG range to Modbus.

The integral controls AUMA MATIC Modbus consist of the following
modules:

.

Modbus interface. The interface links the Modbus data with the internal
electronics.

.

The logic board links the signals of the actuator with the local controls and the
Modbus interface and controls the reversing contactors or the thyristors.

.

Local controls with selector switch, push buttons, and indication lights.
The selector switch is used to select the control devices for the local
control LOCAL – 0 – REMOTE for remote control.
The push buttons (OPEN) – Stop – (CLOSE) are used for the
electric operation of the actuator on site.

.

Plug/ socket connectors for easy mounting of the AUMA MATIC Modbus
on the actuators.

.

Signal and control board with primary fuses, relays for conversion of the
local control commands into electrical signals, and indication lights as an
option.

.

Switchgear: Reversing contactors or thyristors for motor controls.

.

Modbus connection board with terminals for the Modbus cable and the
termination resistor for bus termination.

Actuators which have already been installed can be retrofitted for Modbus
by exchanging the controls AUMA MATIC for controls AUMA MATIC
Modbus.

The settings are described in the operation instructions pertaining to the
actuator (multi-turn actuator SA(R) ... part-turn actuator SG ... ).

For actuators with feedback signal (RWG, potentiometer), a reference oper­ation has to be performed after having changed the setting.

Perform reference operation:

.

Operate actuator electrically (via the push buttons OPEN and CLOSE of
the local controls) once to the end position OPEN and once to the end
position CLOSED.

.

If no reference operation is performed after changing the limit switching,
the feedback signal via the bus is not correct. The bus signals the missing
reference operation as warning (see page 28).

When working in potentially explosive areas, observe the
European Standards EN 60079-14 “Electrical installations in
hazardous areas” and EN 60079-17 “Inspection and mainte­nance of electrical installations in hazardous areas”.

The bus connection is realised via terminals (figure E-1) The terminal

7.9 Redundant bus connection AUMA Modbus devices can be connected with a second (redundant)

Modbus cable. If the bus on channel 1 fails, e. g. through cable break, the
slave automatically switches to channel 2 after a waiting time.
Thus, the change-over is realised with a time delay (see parameter 5
“Time for channel changing in 0.1s”, page 35).
Additionally, the communication cannot be carried out on both channels
simultaneously.
If the redundancy is activated (see parameter 4 “Redundancy”, page 34),
the AUMA MATIC transmits its data using both channels but receives the
data only using the active channel.

This cable redundancy may only be applied after previous
integration test using the desired process control system!

.

For versions with AUMA plug/ socket connector (subclause 7.2):

Connect redundant bus cable to channel 2 in the same way as channel 1
(figure C-2).

.

For Ex-version with plug/ socket connector / terminal board (KP)

(subclause 7.7):

Connect cable B to terminal 6, cable A to terminal 7.
The termination resistor for channel 2 is connected through linking the
terminals 5 – 6 and 7 – 8.

.

For Ex-version with plug-in terminal connection (KES)

(subclause 7.8):

Connect cable B to terminal 6, cable A to terminal 7 (figure E-2).
The termination resistor for channel 2 is connected through linking the
terminals 5 – 6 and 7 – 8.

The setting of the redundant bus connection is realised via the parameters
4 and 5 (refert to pages 34, 35).

18

Actuator controls AUMA MATIC AM/ AMExB/ AMExC
Modbus Operation instructions

7.10 Bus cables Only cables according to the recommendations of EIA 485 standard may be

used for Modbus wiring.

A maximum of up to 32 Modbus devices may be connected in one segment.
If more stations are to be connected to one Modbus network, several
segments must be connected with repeaters.
The bus cable must be laid at a distance of at least 20 cm from other cables.
It should be laid in a separate, conductive, and earthed cable trunking.
It must be ensured that there are no potential differences between the indi­vidual devices on the Modbus (perform a potential compensation).

The max. cable length without repeater amounts to 1,200 m (independent of
the baud rate).

Cable recommendation for Modbus

Characteristic impedance: 35 to 165 Ohm, at a measurement

frequency of 3 to 20 MHz.
Cable capacity: < 30 pF per metre
Core diameter > 0.64 mm
Core cross section: > 0.34 mm², corresponds to AWG 22
Loop resistance: < 110 Ohm per km
Screening: copper shielding braid or shielding braid and

shielding foil

7.12 Setting the communication parameters

Push buttons:

T1 RESET
T2 MODIFY
T3 CHANGE MODE:

DEFAULT MODE: for status indication and basic programming,
ADDRESS MODE for address setting
BAUD RATE MODE for baud rate selection

Push button 3 (CHANGE MODE) is used to switch between the following
modes:

1) DEFAULT MODE is characterised by LED 7 (green) being switched off.

Display and modification of type of seating in end position CLOSED,
parity bits and stop bits as well as display of DataExchange, status,
BusActivity, and LocalError.

2) ADDRESS MODE is characterised by LED 7 (green) being illuminated.

The address is adjustable.

3) BAUD RATE MODE

is characterised by the blinking of LED 7 (green).The baud rate is adjustable.If no

push buttons are pressed for 30 seconds, the display will revert to DEFAULT MODE.
The push button MODIFY allows incrementation of the figure shown in the
LED row. The new value is immediately accepted in the DEFAULT MODE.
For ADDRESS MODE and BAUD RATE MODE, the value is only accepted
when leaving these modes.

7.13 Setting parameter seating mode in end position CLOSED, parity bits and number of stop bits

When not pressing push button CHANGE MODE, you are in the DEFAULT
MODE (LED 7 is not illuminated). LED 0, LED 1, and LED 2 show the value

of the three mentioned parameters:

Push button S3 “MODIFY” is used to set these parameters. If, for example,
type of seating in end position CLOSED = torque seating, parity setting =
even parity, and number of stop bits = 1 stop bit is to be selected, the combi­nation 001 must be illuminated for the first 3 LEDs. The push button
“MODIFY” is operated until this combination appears. The parameter values
become immediately valid.

7.14 Setting the Modbus address The Modbus address is set using push buttons T2 and T3. This is done

according to the following sequence:

(a) Press push button T1 CHANGE MODE (hold down for 1 to 2 seconds):

The green LED 7 ADRESS MODE is illuminated (not blinking);
it indicates the programming mode for the Modbus address.
The actually set Modbus address is displayed as binary coding by LEDs
6 to 0 (1 to 127).

(b) Set desired bus address using push button T2 MODIFY:

(Factory setting: slave address 2)

(c) Each pressing of the push button increments the address value by one.

Address 1 will follow after address 127. If push button T2 MODIFY is
held down (approx. 1/3 s), the incrementation is done automatically.

Operation instructions Modbus

LED Parameter LED on LED off

0 seating mode in end position CLOSED torque seating limit seating
1 Parity setting No Parity Even Parity
2 Number of stop bits 2 stop bits 1 stop bit

(d) After setting the required Modbus address, quit the programming mode

by pressing key T3 CHANGE MODE. The newly set address now
becomes valid.
Pressing the key T3 results in changing to BAUD RATE MODE;
renewed pressing of key 3 results in reverting to DEFAULT MODE.

(e) Alternatively to clause d), pressing the push button T3 may be ommitted.

After 30 s the status address mode is automatically quit and the

DEFAULT MODE is indicated. The set address is thus accepted.

7.15 Setting the baud rate

The baud rate is selected with the push buttons T2 and T3. This is done
according to the following sequence:

(a) Press push button T3 CHANGE MODE (hold down for 1 to 2 seconds):

The green LED 7 is illuminated (not blinking): the ADDRESS MODE is
active.

(b) Press push button T3 CHANGE MODE again (hold down for 1 to 2

seconds): The green LED 7 is blinking: now, the BAUD RATE MODE is
active.

(c) Select the desired Modbus baud rate pressing push button T2 MODIFY.
(d) The baud rate setting changes each time, push button T2 is pressed.

After the setting 56,400 bit/s (1001), the setting 110 Bit/s (0000) follows
again. If push button T2 MODIFY is held down (approx. 1/3 s), the
incrementation is done automatically. Only the first 4 LEDs count as only
10 baud rate settings are possible.

(e) After setting the required Modbus baud rate, close the programming

mode by pressing push button T3. The newly set baud rate becomes
valid and the interface is in DEFAULT MODE.

(f) Alternatively to clause e), pressing the push button T3 CHANGE MODE

may be omitted. After 30 s, the BAUD RATE MODE status is
automatically quit and the DEFAULT MODE is indicated. The set baud
rate is thus accepted.

10. Process representation output

Via the process representation output, the master (controls) can control the
slave (actuator).

10.1 Transmitting operation commands to or reading out from the actuator using register functions

Functions to be used:
Preset Single Register (06); Preset Multiple Register (16);
Read Holding Register (03)

10.2 Description of the output data

Register 1: Commands (high byte)

With the bits 0 – 2, the opera­tion commands are transmit­ted to the actuator.Only one of
these bits may be set at any
given time. If remote
SETPOINT is set, the value of
the nominal position
(register 2) is used.
Bits3–15arereserved for fu­ture extensions and must re­main set to 0.
As soon as these bits are writ­ten to via coil functions, the
contents of the respective
Holding Registers for the op­eration commands will also
change.
If the Coil Remote SETPOINT
is used, the respective
setpoint has to be entered on
the setpoint register.

Register 2: E1 Setpoint

The setpoint can be transmit

­ted either as a value between
0 – 100 (percent) or 0 – 1000
(per mil). The cange-over be­tween 0 – 100 and 0 – 1000is
realised via parameter 2
“Measured data coding posi­tion transmitter”. According to
this programming, different
maximum values apply. When
these limits are exceeded, the
actuator stops and signals a
fault.

10.3 Transmission of operation commands to the actuator using coil functions

Functions to be used:
Force Single Coil (05)
Force Multiple Coils (15)
Read Coil Status (01)

If a Force Coil is set, the other two coils will be deleted by the actuator
(the actuator executes the last command issued).
Coil operation commands also change the corresponding holding register
for the operation commands.

Operation commands which cannot be executed are rejected with ILLEGAL
DATA VALUE (code 03). Operation commands cannot be executed if:

.

a thermal fault or a power failure have occurred.

.

the remote controls is not set to REMOTE.

.

an impermissible nominal value has been set (>100 or >1000).

.

commands are contradictory (coil contents at Force Multiple Coils or

holding registers contradictory).
If a thermal fault or a power failure occurs during remote operation or if the
remote operation is switched off, the actuator will cancel the pending opera­tion commands.

11. Operation parameters of the actuator

Functions to be used:

The parameters of the AUMA MATIC can be written or read using the
following functions:
Preset Single Register (06),
Preset Multiple Register (16), or
Read Holding Register (03)

Parameters should only be changed as a whole parameter record in order to
avoid inconsistent parameter records. The Modbus software checks the
consistency of parameters and refuses inconsistent parameter records
(ILLEGAL DATA VALUE, code 03).

Parameter 1 “Position transmitter”

Holding Register Offset: 0x4000 (hex.), 16384 (decimal)

Default value (standard setting): 1
0: The actuator is not equipped with a position transmitter.
1: The actuator is equipped with a potentiometer without RWG.

Switch S1.2 on Modbus board must be switched off!

2: Actuator is equipped with an RWG 0 – 20 mA.

For this position transmitter, the signal interruption noitoring is not active.
Switch S1.2 must be switched on!

3: Actuator is equipped with an RWG 4 – 20 mA.

For this position transmitter, the signal interruption monitoring is active.
Switch S1.2 on Modbus board must be switched on!

Parameter 2 “Measured data coding position transmitter”

Holding Register Offset: 0x4001 (hexadecimal), 16385 (decimal)

Default value: 0
0: Feedback signal (register 3, E2 actual position) 0 to 100 percent,

resolution is 1 %,
setpoint (register 2, E1 actual position) 0 to 100 percent.

1: Feedback signal (register 3, E2 actual position) 0 to 1000 per mil,

resolution is 0.1 %,
setpoint (register 2, E1 actual position) 0 to 1000 per mil.

Parameter 3 “Reversing prevention in ms”

Parameter for setting the waiting time in between a change of direction.
If necessary, adjust the value to the mechanics to prevent destruction
caused by excessively fast changes of direction.
Holding Register Offset: 0x4002 (hexadecimal), 16386 (decimal)

Default value: 200
lowest value: 100 (0.1s)
maximum value: 1000 (1 s)

Parameter 4 “Redundancy”

Holding Register Offset: 0x4003 (hexadecimal), 16387 (decimal)

Default value 0
0: no cable redundancy (only the first channel is used for communication).
1: Cable redundancy is switched on (first and second communication

channel connected).

34

Actuator controls AUMA MATIC AM/ AMExB/ AMExC
Modbus Operation instructions

Parameter 5 “Time for channel changing in 0.1 s”

Indicates the time after which the channel is changed if no process data, i.e.
expiry of connection control time of 0.1 s, is received. This parameter is only
effective if the cable redundancy (parameter 4) is switched on.

Holding Register Offset: 0x4004 (hexadecimal), 16388 (decimal)

Default value: 50
lowest value: 50 (5 s)
maximum value: 6000 (10 min)

Parameter 6 “Failure behaviour”

Failure operation on failure of connection.
The parameters set in the most recent connection also apply to the failure
behaviour after interruption and restoring of the voltage supply.

Holding Register Offset: 0x4005 (hexadecimal), 16389 (decimal)

Default value: 0
0: Failure behaviour switched off (parameters 7, 8, 9 insignificant)
1: Simple failure behaviour switched on.

A failure operation will only be started if a connection to the master
(process data exchange) was already available.

2: Extended failure behaviour switched on.

If extended failure behaviour is switched on, a failure opera­tion can be initiated immediately after the actuator has been
switched on.

Parameter 7 “Delay time for failure operation 0.1 s”

Delay time for failure operation in 0.1 s.
Indicates the down time of process data exchange after which a failure oper­ation will be started. If the exchange is restored during this time, no failure
operation will be performed.

Holding Register Offset: 0x4006 (hexadecimal), 16390 (decimal)

Default value: 30
lowest value: 0 (actuator reacts immediately)
maximum value: 12,000 (actuator reacts after 20 minutes)

Parameter 8 “Failure operation”

Holding Register Offset: 0x4007 (hexadecimal), 16391 (decimal)

Default value 0
0: The actuator stops (STOP).
1: Actuator runs CLOSE
2: Actuator runs OPEN
3: Actuator runs to failure position.
If no position transmitter is installed (parameter 1 = 0), value 3 is not
permitted. In this case, the parameter record is rejected.

Parameter 9 “Failure position in per mil”

Actuator runs to the pre-set failure position.

This parameter is only effective if parameter 8 (failure operation) is set to
value 3, and if parameter 6 (failure behaviour) is not 0.

Holding Register Offset: 0x4008 (hexadecimal), 16392 (decimal)

Default value: 0
lowest value: 0 (end position CLOSED)
maximum value: 1,000 (end position OPEN)

Operation instructions Modbus

Parameter 10: not used

For detailed descriptions of parameters 11 to 14, please refer to
subclause 12.2

Parameter 11 “Dead time positioner in 0.1 s”

Indicates the dead time which has to be maintained between two motor
starts. In case the Modbus master issues a command before that time, the
AUMA MATIC delays the actuator reaction until dead time has expired.

Holding Register Offset: 0x400A (hexadecimal), 16394 (decimal)

The Modbus master of the controls must ensure that the
maximum number of motor starts of the actuator is not
exceeded.

Default value: 0
minimum value: 0 (actuator reacts immediately)
maximum value: 600 (actuator delays reaction by 1 minute max.)

Parameter 12 “Overrun direction OPEN in per mil”

The motor is switched off as soon as the distance between the actuator
position and the nominal position reaches this value. This is only valid for
operations in direction OPEN.
This parameter must be lower than the value in parameter 14 (max. error in
per mil).

Holding Register Offset: 0x400B (hexadecimal), 16395 (decimal)

Default value: 5
minimum value: 0 (no overrun in direction OPEN)
maximum value: 100 (10 % overrun in direction OPEN)

Parameter 13 “Overrun direction CLOSE in per mil”

The motor is switched off as soon as the distance between the actuator
position and the nominal position reaches this value. This is only valid for
operations in direction CLOSE.
This parameter must be smaller than the value in parameter 14 (max. error
in per mil).

Holding Register Offset: 0x400C (hexadecimal), 16396 (decimal)

Default value: 5
minimum value: 0 (no overrun in direction CLOSE)
maximum value: 100 (10 % overrun in direction CLOSE)

Parameter 14 “Max. error in per mil”

The actuator will only be restarted if the distance between the nominal posi­tion and the actual position is higher than this value.
Corresponds to the outer dead band.
This parameter must be higher than the value in parameter 12 (overrun in
direction OPEN) and parameter 13 (overrun in direction CLOSE).

The parameter must be set sufficiently high to ensure a
stable function of the positioner. If the value is set too low,
the actuator moves continuously within nominal value range
which will result in reducing the life time of the actuator.

Holding Register Offset: 0x400D (hexadecimal), 16397 (decimal)

Default value: 10
minimum value: 1 (0,1 % error).
maximum value: 100 (10 % error).

bits are set, no operation is performed and the fault signal ‘Wrong command’
is given.
To avoid placing too much strain on the mechanics the actuator is equipped
with a (programmable) delay when changing direction (reversing preven­tion).

The following operation command bits are required for OPEN/ CLOSE
operation:

Remote OPEN
Remote CLOSE

Remote operation OPEN / STOP

Remote OPEN = 1 The actuator runs in direction OPEN.
Remote OPEN = 0 The actuator stops.

The actuator is switched off automatically if the end position OPEN
(limit switch LSO [WOEL]) is reached.
Occurring faults (thermal protection, phase failure, torque failure) stop the
operation.

Remote operation CLOSE/ STOP

Remote CLOSED = 1 The actuator runs to position CLOSED.
Remote CLOSED = 0 The actuator stops.

The actuator is switched off automatically if the end position CLOSED is
reached (limit switch LSC [WSR] for limit seating or LSC [WSR] and TSC
[DSR] for torque seating). Occurring faults (thermal failure, phase failure,
torque failure) stop the operation.

Remote operation to setpoint position/ STOP

The positioner can only function if the actuator is equipped with a position
transmitter, e.g. potentiometer/ RWG (option).

Remote SETPOINT = 1 The actuator moves to the set nominal value.
Remote SETPOINT = 0 The actuator stops.

The setpoint must be indicated in % or in ‰ (depending on the AUMA user
parameter 2 “Measured data coding position transmitter”.
Occurring faults (thermal failure, phase failure, torque failure) stop an oper­ation via the positioner.

With a setpoint of 0 % (0 ‰), the actuator runs to the end position CLOSED.
With a setpoint of 100 % (1000 ‰), the actuator runs to the end position
OPEN. In case the setpoint is more than 100 % (1,000 ‰) , no operation is
performed and the fault signal “Wrong command” is given.

12.2 Positioner The positioner is activated via the bit ‘Remote SETPOINT’.

The positioner is a three-position controller. Via the setpoint E1 in the
process representation output, the nominal value of the position is trans­mitted to the actuator as nominal variable.

The positioner integrated in the actuator controls AUMA MATIC provides the
position signal for controlling the motor depending on the nominal and
actual position value. The feedback signal (actual position E2) is produced
internally within the actuator.

The position transmitter compares the nominal value of the position set in
the controls to the locally measured actual value of the position. If the differ

­ence between nominal value and actual value is higher than the max. error
(parameter 14), the positioner drives the motor, depending on the error,
either in direction OPEN or direction CLOSE.

41

Actuator controls AUMA MATIC AM/ AMExB/ AMExC

Operation instructions Modbus

Overrun (inner dead band) The inner dead band determines the switching-off point of the actuator.

The tripping point in both directions can be set via the parameters 12 and
13 (page 35), so that the actuator stops as close as possible to the nominal
value.

Max. error (outer dead band)

The outer dead band determines the switching-on point of the actuator.
If the actual position or a change in nominal value is higher than the max.
permissible error set with parameter 14 (page 36), the motor is started.

The parameter must be set sufficiently high to ensure a
stable function of the positioner. If the value is set too low,
the number of starts is likely to be increased. Thus, the end
of the lifetime of the actuator and valve will be reached
sooner.

Dead time The dead time prevents the operation to a new nominal position within

a pre-defined time period. The time can be between
0 and 1 minute and is set in parameter 11.

The controls must ensure that the maximum number of
motor starts of the actuator is not exceeded. This can be
achieved by setting the parameter 11 to a sufficiently high
value.

For further information on the positioner, please refer to the operation
instructions pertaining to the actuator (multi-turn actuator SA(R).../ part-turn
actuator SG... with AUMA MATIC AM...).

12.3 Stepping mode Stepping mode requires a position transmitter (option).

The stepping mode lengthens the operating time for part of or for the whole
travel.

Setting operation and pause times as well as stepping ranges

The operation and pause times (stepping times) in opening or closing direc­tion are set with the parameters 27, 28 and 32, 33. An individual operation
and pause time can be set for each direction.
The stepping ranges can be set separately in direction OPEN and CLOSE
(parameter 29, 30 and 34, 35).

Indication of operation in stepping mode

The states of the operation in stepping mode are indicated by the bits 2 and
3 in register 6 of the process representation input.

13. Failure function The failure function allows the start of failure operations in case of special

events, e.g. when the communication between the actuator and the master
is interrupted. This function is set with the parameters 6 to 9.

If the actuator is in the failure function, the set failure position is approached
via a failure operation.
If the actuator is then moved to another position (e.g. by manual operation),
it will try to perform the set failure action while the selector switch is in posi­tion REMOTE.

To prevent a new approach to the failure position during
manual operation, the selector switch (local controls) must
be switched to position ‘LOCAL’ or ‘OFF’ before operating
the handwheel.

The following events can trigger the failure function:

.

The connection to the master is interrupted.

.

The master sends no telegrams to the actuator.

As soon as the cause for triggering the failure function is eliminated
(connection restored, master in Operate state), the operation commands
from the master can be executed again.

The last operation command having been transmitted to the
actuator prior to the connection failure is deleted within the
actuator. To ensure a defined behaviour, a valid operation
command must be transmitted to the actuator upon
resuming communication.

Time behaviour of the failure function

The internal connection control time (1 s) is started with the last Modbus
query-response cycle prior to communication failure.
If no valid Modbus telegram was received within this connection control
time, the failure function will be initiated with the start of the delay time. At
the end of the delay time, the failure action will be executed:

in position On.

S1.2 Switch for setting the position feedback via position transmitter potentiom-

eters/ RWG (option).
S1.2 = OFF:

The actuator is equipped with a potentiometer.

S1.2 = ON:

Switch may only be in this position if an RWG (0/4 – 20 mA) is

installed in the actuator.

14.1 Indication during system start-up

When starting the system, the LEDs 0 to 7 will be illuminated. LEDs L1 to L4
are switched off. This signifies that the board is correctly started.
After a short time (approx. 1/4 s), the LED L1 (round red LED) will be illumi­nated and the LEDs 0 to LED 7 will be switched off one after the other. This
means that the microcontroller is now operating. If LED L1 is switched off
and the LEDs 0 to 7 are still illuminated, then the system is in the reset
status (this situation can also be reproduced by constantly pressing push
button T1).

14.1.1 Indications of operation LEDs 7 to 0

LED 0 Indicates torque or limit switching in end position CLOSED

(illuminated for torque switching)

LED 1 Indicates the quantity of the parity bits from the Modbus protocol

(illuminated for No Parity). Only No Parity and Even Parity are
supported, Odd paritiy is not supported

14.2 Customer input assignment of the Modbus interface (option)

X7 Digital inputs This plug provides pins for 4 digital customer inputs.

These signals are freely available inputs which the microcontroller transmits
into the process representation input (register 7, bits 0 – 3). The inputs are
galvanically isolated and internally connected to 0 V via pull-down resistors.
In an unconnected state, a logical zero is transmitted. To set an input to
logical one, + 24 V DC must be applied (pins 5 or 6).

.

For these signals, proposed external wiring diagrams
(appendix B) must be observed.

.

The bounce time of the connected switches should not be
more than 1 ms.

X11 Second analogue input (analogue 3/4)

An external 0/4 – 20mA sensor for transmitting the measured values via the
Modbus can be connected to this input.

If switch S1.1 is set to position ON, then pin 5 (AN 3/4+) is connected to
GND and input AN 3/4– can be used in the same way as AN 2.
If the switch is set to position OFF, a differential measurement between AN
3/4+ and AN 3/4– can be performed.

X12 First analogue input (analogue 2).

An external 0/4 – 20mA sensor for transmitting the measured values via the
Modbus can be connected to this input.

.

Potential-free differential measurement is not possible due
to the presence of a permanent ground (GND) connection.

.

For these signals, proposed external wiring diagrams
(appendix B) must be observed.

.

The inputs AN2, AN3, and AN4 do not have galvanic isola­tion via opto-isolator. The maximum load of the 24 V DC
voltage source applied by the sensors must not exceed
40 mA altogether.

15.2 Position feedback does not function

.

Check if the voltage at plug (X1) on the Modbus board, pin 3 (-) and pin 2
(+) is subject ot linear incrementation when running open and linear
decrement when running close.
The value for position CLOSED should be within the range of 0 to 2 V.
The value for position OPEN should be within the range of 3 to 5 V. The
voltage difference between CLOSED and OPEN should be superior to 3V.

15.3 Actuator is not switched off by the limit switch in direction CLOSE

The actuator is set to torque seating.
Set actuator to limit seating:

.

Set switch S4 (see figure H, page 44) on the Modbus board to position
‘LIMIT’.

.

Adjust switch S1-2 on the logic board (see page 47) to position 1.

15.4 Actuator stops immediately after having started

.

Set switch S2-2 (blinker transmitter) on the logic board to position ‘ON’.

15.5 Actuator does not signal reference operation, connection failure position transmitter or signal
interruption position transmitter

The position transmitter (potentiometer, RWG) is faulty.

.

Check position transmitter wiring and connection

.

Check the setting of parameter 1 “Position transmitter”

.

If the actuator is not equipped with a position transmitter, parameter 1 has
to be set to value 0 (no position transmitter)

15.6 Measuring the Modbus signals using an oscilloscope

On the Modbus board, the signal from Modbus channel 1 on the plug (X8
Modbus, refer to page 46) pin 1 (P/B) and pin 2 (N/A) can be checked using
a digital oscilloscope.
The off-load voltage between pin 1 (+) and pin 2 (-) must be positive and
within the range of 0.8 V and 1.4 V.
