Auma multi-turn actuators of the type range SA
can be used wherever the automation of the
valve is required. The adoption to the
requirements of nearly every valve automation
task is possible. This is on account of :
An extermely wide torque range
Various combination possibilities with
Auma Valve Gear boxes. Thereby the torque
range can be further extended and / or the
multiturn actuator can be converted into
part turn, lever or linear actuator.
A large variety of versions, whether for open
or closed loop control, explosion proof
applications, a suitable version is available.

Design Principle
Especially high starting torque is frequently
required to unseat valves from end positions.
The motors developed by Auma fulfil this
basic requirement.
Change GearsValve Attachment
Auma actuators are driven by special
combination of gears which are outside the
grease filled housing & require no lubrication.
If required, output speed can be easily altered
by changing the gear pair and / or motor at
site.
Reduction GearingManual Operation
A well proved principle of worm gearing is
used to reduce the motor speed to required
output speed of actuator. Self-locking feature
is achieved by worm gearing upto 90 output
rpm. Worm shaft and output shaft with worm
wheel run in ample sized bearings. The sliding
worm is positioned between two sets of
springs on worm shaft. The worm moves
axially in relation to thrust which is the
measure for torque. Via lever & gears the
torque is transmitted to control unit.
All electrical connections are terminated inside
the terminal compartment. Screw type terminals
are provided for easy connections. Multi-pin
plug-socket connector can be provided for ease
of connections & maintenance.
The mounting flange is according to ISO 5210 /
DIN 3210. Various output drives are available for
for adaption to various types of valves.
For commissioning or in an emergency, actuator
can be operated with hand wheel. When starting
the motor, the manual drive is automatically
disengaged.
Switch Compartment
Depending upon type of valve, the actuator
must be switched off at end positions by limit
switch or torque switch. For this purpose,
independent limit switching or torque
switching devices are provided in the switch
compartment. The switching devices are easily
accessible for any setting at site.

Functions
Open Close Duty
The characteristic feature of this actuator is
open loop. The normal valve positions in
OPEN-CLOSE Duty are end positions OPEN
and CLOSED. After receiving command, the
actuator operates the valve to one of the end
positions or if necessary to a preset
intermediate position. The valves are operated
relatively seldom, the time intervals can span
between a few minutes to several months.
Auma multi-turn actuators type SA for open
close service are rated for short time duty
S2-15min.
Regulating / Modulating Duty
Typical Characteristics of
OPEN-CLOSE DUTY
The characteristic feature of this actuator is
closed loop in which input command signal to
actuator is directly influenced by the flow
through the valve. Regulating / Modulating
duty actuator SAR operates between two set
bands between open-close positions depending
upon actual valve position and feedback signal.
The motors of these actuators are rated for
intermittent duty S4-25%. The mechanical
components and motor are designed to withstand
a large number of operations required for
modulating applications.
Typical Characteristics of
Regulating / Modulating Duty
Pemissible number of starts-stops depends upon
actuator size & speed. The details are available
in Data Sheets.
Short Time and Intermittent Duty IS 12824

Limit Switching
Functions
The limit switching enables to switch off the
actuator when reaching defined valve
position, usually end positions. The valve
travel is measured by mechanical counter gear
mechanism which when reaching the set
Two Train Counter Gear
For Two train counter gear, two limit switches,
one for each direction of travel having 1 NO
+ 1 NC or 2 NO + 2 NC contacts are provided.
The number of spindle turns can be set
between 1 and 480 or 1 and 4800.
switching points operate the electrical limit
switches by cams. The setting accuracy is 1/10 of
a turn of actuator output shaft.
In limit switching, two train counter gear and
four train counter gear versions are available :
Four Train Counter Gear
If limit switching is required at two end
positions only, two train counter gear is used.
However, if two additional intermediate
switching positions are desired, Four Train
Counter Gear is required. This limit switching
has 4 counter gears and 4 micro switches. Two
counter gears are used to switch off at end
positions as in Two Train Counter Gear. The
other two are available for setting any desired
intermediate positions between end positions.
After cam actuation, the switches remain
actuated till reaching end of valve travel.
Examples of such application are :
To stop at intermediate position
Sequence control, that is to start
another equipment like pump or bypass
valve actuator after certain travel
of valve.
Two Train Counter Gear
The accuracy of setting is 1/10 of a turn of
actuator output shaft. For four train counter
gear, 4 limit switches of 1 NO + 1 NC or 2 NO
+ 2 NC contacts are provided.
Four Train Counter Gear

Functions
Torque Switching
The torque switching enables to switch off the
actuator when pre-determined torque is
reached instead of a defined position. The
torque switching works on principle of sliding
worm.
Axial displacement of worm proportional to
thrust is transmitted to torque switches.
Torque switches operate in closing & opening
directions. The required tripping torque can be
easily set on the graduated dial. If limit switch
cut off is selected prior to torque switch, then
torque switch serves as overload protection.
For tight seating of certain valves, the actuator
must be operated to end position CLOSED
with defined force. Such operation can be
carried out by torque seating. Limit seating is
commonly used in the end position OPEN.
Running Indication
Blinker switch is provided in the actuator and
can be used as running indicator.
Torque Switching
When torque seating is used at end position,
limit switches can be used for signalization.
Therefore actuator controls can differentiate
whether actuator was switched off by torque
switch or by limit switch. Micro switches of
torque switching are provided with 1 NO + 1 NC
or 2 NO + 2 NC contacts for both open & close
directions.
10
Page 11
Micro Switches
Control Equipment
With the help of micro switches, mechanical
parameters such as travel & torque are
converted into electrical signals for actuator
control. There are four switches in the basic
version :
One limit switch each for the end
positions OPEN and CLOSE
One torque switch each for the
directions OPEN and CLOSE.
Single and Tandem Micro Switches
Limit and Torque Switches are available in
single or tandem versions.
Limit switches are tripped when an end position
is reached and torque switches are tripped when
the set tripping torque is exceeded.
The micro switches are sealed to enclosure
protection class IP66, as per IS 13947. The micro
switches have double break change over
potential free contacts. The circuit is interrupted
simultaneously at two points. The basic versions
of the switch contacts are of silver. For low
current ratings, micro switches with gold plated
contacts are available.

Control Equipment
Reduction Gear Unit
A reduction gear unit (RGU) in the actuator is
used for mechanical position indication,
remote position indication & for operation of
intermediate switches. The output shaft of the
actuator drives final output shaft of RGU
through a series of reduction gears and final
shaft turns by approximately 270 while
o
actuator output shaft performs full number of
turns as set on two train or four train counter
gear unit. The reduction gear ratio needed for
each particular case is fitted at works if the
ratio is known. For this purpose fixed RGU
is supplied. If the ratio needs to be altered
Position Indicators
Mechanical Position Indicator
The position of the valve is indicated
continuously by adjustable discs having
symbols for OPEN and CLOSE. The discs can
be seen through an indicator glass on switch
compartment cover. The open-close discs can
be set to coincide with limit switching. The
mechanical position indicator requires
reduction gear unit for operation.
at site, variable ratio RGU is available which
allows simple modification at site depending
upon number of turns of output shaft for full
stroke of valve.
Reduction Gear Unit (RGU)
Remote Position Indicator
The position of the valve can be transmitted as
a continuous signal for remote indication. A
potentiometer mounted on RGU is used for
this purpose. A power supply unit provides
necessary voltage to the potentiometer. The
potentiometer rotates through 270 for one full
o
stroke of valve & output signal from
potentiometer is proportional to valve travel.
Thus the actual position of the valve can be

read off continuously on position meter
calibrated & mounted on control panel.
Actual position display can be provided by
digital remote position indicator, which
displays open position in percentage.

Intermediate Switches
With this limit switching, additional switching
points can be set for each direction of rotation.
The switching can be set between 25 and 75%
of valve travel in each direction. The switch
sub assembly consisting of 2 or 4 cam switches
is mounted on output shaft of RGU. Each
micro switch has 1 NO + 1 NC contact.
Manual Operation
For commissioning or in an emergency when
there is no power supply, actuator can be
operated by hand wheel. The manual drive is
engaged by means of a lever. When motor
starts running, the manual drive gets
disengaged immediately & hand wheel does
not rotate during power operation.

Intermediate Switches
In manual operation, hammer blow can be
effected with hand wheel. The hammer blow
makes it possible to open a jammed or rarely
operated valve.

Motors
As a standard, Auma multi turn actuators are
equipped with 3 phase induction motors.
Auma motors are class F insulated and
withstand winding temperature upto 140 C.
o
The motors are used for short time duty (S2-15
min or S4-25% as per IS 12824) and provide
approximately three times rated torque for
short duration. The size of the motor is smaller
compared to continuous duty motor S1 of
same output power. This results in reduced
inertia of the rotor and therefore less
overshoot after switching off of motor. Auma
motors are designed for enclosure protection
class IP 68 when mounted on the actuator. All
motor cables are brought to terminal
compartment cover from inside of the actuator
thus avoiding terminal box.
Technical Data
Single Phase AC Motors
Auma actuators can be supplied with single
phase AC motor. The required capacitor is fitted
in the terminal compartment cover.
DC Motors
Auma actuators are also available with DC
motors. These motors operate on 24 V, 110 V or
220 V DC supply.
AC Motors with Other Voltages and
Frequency
Three phase induction motors are available in
wide range of operating voltages from 220 V to

Motor Protection
Control Equipment
Motor winding may get overheated if the
actuator is run beyond rated duty or if the
rotor is stalled for considerably longer time or
if too high ambient temperature is
encountered. In order to protect the motor
against over heating, thermo switches are
embedded in the windings of three phase,
single phase AC motors and DC motors. When
integrated into the control circuits, they will
protect the motor against damage due to
excessive winding temperature.
The thermo switches interrupt the control
circuit as soon as winding temperature of
o
140 C is exceeded. After cooling down to a
temperature of approx. 110 C, the actuator can
o
be switched on once again. PTC thermistors
can also be provided for motor protection.
Output Speeds
With large range of available output speeds,
almost every required operating time can be
achieved with Auma actuators.
The actuator output speed is determined by
the motor speed, change gears and reduction
gear ratio of worm / worm wheel.
The output speeds are available from 4 - 180
rpm in geometric progression of 1: 1.4.
During trial run, if found necessary, the
output speed can be easily changed by

exchanging the change wheels and or motor at
site. The grease filled housing need not be
opened for this purpose. The torque switch
setting & limit switch setting remains the same.
For actuators with output drive A (Stem nut),
max. permissible stem velocity must be
observed:
-
for gate valves max. 500 mm/min
-
for globe valves max. 250 mm/min
For higher velocities it is recommended to use
spring loaded stem nut type AF (special design).
Self Locking
Auma multi turn actuators SA/SAR3 to
SA/SAR100 are self locking (see note below)
with exception of output speeds 125 & 180
rpm. Actuators with 125 & 180 rpm are having
double start worm drive. After torque switch is
tripped, the sliding worm may move back to
initial position by the action of torque
measuring springs. This allows torque switch
to be released. If control system provides
continuous signal, this results in hunting of
motor. This can be avoided by the use of
auxiliary relay.
Note on Self Locking :
Self-locking gearing does not ensure safe
stopping after an operation. If this is required,
separate locking arrangement must be provided.

Actuators for Regulating Duty
Description of Regulating Duty
Auma actuators of type SAR are suitable for
Regulating duty / Modulating duty. SAR
actuator operates between two set bands in
closed loop and the motor is started, stopped
& reversed at short intervals to correct the
deviation from the set value. SAR actuators
differ from SA actuators in several respects :
- 4 pole motors are used to reduce overshoot
- Worm with high quality finish on flanks for
better efficiency
-
Disc springs on worm shaft are pre
compressed to reduce dead band when
reversing.
While selecting Auma actuators for regulating
duty applications, following points should be
noted :
Principle of Operation
Max. No. of starts-
1200 cycles / hour with motor power upto
0.55 kW & 600 cycles / hour with motor
power above 0.55 kW.
Output speed of actuator max. 45 rpm.
-
-
Torque for regulating duty should not exceed
50% of max. torque of actuator.
-
Max. torque of actuator can be used for
seating & unseating of the valve.
For reversing service, duration of impulse
should be minimum of 50 ms.
-
Electronic position transducer or precision
potentiometer should be used for remote
position indication.
-
The motor should be short time duty
class S4 - 25%.

Actuators are rated for Intermittent duty S - 25% ED, based on 40 C ambient temperature. The nominal current is based on an
o
average load of approximately 35% of max. torque. The max. torque can be utilised for a short time (e.g. to seat or unseat
a valve) and the current can rise to max. value. Refer corresponding column for current at max. torque in Electrical Data.
1) Infinitely adjustable 2) At 50 Hz
