Standards/directives Our products are designed and manufactured in compliance with recognised
standards and directives.This is certified in a Declaration of Incorporation and an
EU Declaration of Conformity.
The end user or the contractor must ensure that all legal requirements, directives,
guidelines, national regulations and recommendations with respect to assembly,
electrical connection, commissioning and operation are met at the place of installation.
They include among others standards, directives on operation in nuclear power
plants and regulations on radiation protection in nuclear power plants.
Safetyinstructions/warn-
ings All personnel working with this device must be familiar with the safety and warning
instructions in this manual and observe the instructions given. Safety instructions
and warning signs on the device must be observed to avoid personal injury or property
damage.
Qualification of staff Assembly, electrical connection, commissioning, operation, and maintenance must
be carried out by suitably qualified personnel authorised by the end user or contractor
of the plant only.
Prior to working on this product, the staff must have thoroughly read and understood
these instructions and, furthermore, know and observe officially recognised rules
regarding occupational health and safety.
Work performed in radiation exposed areas is subject to special regulations which
have to be observed.The end user or contractor of the plant are responsible for
respect and control of these regulations, standards, and laws.
Commissioning Prior to commissioning, it is important to check that all settings meet the requirements
of the application. Incorrect settings might present a danger to the application, e.g.
cause damage to the valve or the installation.The manufacturer will not be held
liable for any consequential damage. Such risk lies entirely with the user.
Operation Prerequisites for safe and smooth operation:
●Correct transport, proper storage, mounting and installation, as well as careful
commissioning.
●Only operate the device if it is in perfect condition while observing these instruc-
tions.
●Immediately report any faults and damage and allow for corrective measures.
●Observe recognised rules for occupational health and safety.
●Observe national regulations.
●During operation,the housing warms upandsurfacetemperatures >60°C may
occur.To prevent possible burns, we recommend checking the surface temper-
ature using an appropriate thermometer and wearing protective gloves, if re-
quired, prior to working on the device.
Protective measures The end user or the contractor are responsible for implementing required protective
measures on site, such as enclosures, barriers, or personal protective equipment
for the staff.
Maintenance To ensure safe device operation, the maintenance instructions included in this manual
must be observed.
Any device modification requires prior written consent of the manufacturer.

2.2. Short description
Multi-turn actuator Definition in compliance with EN 15714-2/EN ISO 5210:
A multi-turn actuator is an actuator which transmits torque to a valve for at least one
full revolution.It is capable of withstanding thrust.
AUMA multi-turn actuators SAI 07.2 –SAI 16.2/SARI 07.2 –SARI 16.2 are driven
by an electric motor and are capable of withstanding thrust in combination with output
drive type A.For manual operation, a handwheel is provided. Switching off in end
positions may be either by limit or torque seating. Actuator controls are required to
operate or process the actuator signals.

Hovering load!
Risk of death or serious injury.
→Do NOT stand below hovering load.
→Attach ropes or hooks for the purpose of lifting by hoist only to housing and NOT
to handwheel.
→Actuators mounted on valves: Attach ropes or hooks for the purpose of lifting
by hoist to valve and NOT to actuator.
→Actuatorsmountedto gearboxes:Attachropesor hooks for thepurpose of lifting
by hoist only to the gearbox using eyebolts and NOT to the actuator.

→Cover to protect against dust and dirt.
→Apply suitable corrosion protection agent to uncoated surfaces.
Long-term storage For long-term storage (more than 6 months), observe the following points:
1. Prior to storage:
Protect uncoated surfaces, in particular the output drive parts and mounting
surface, with long-term corrosion protection agent.
2. At an interval of approx. 6 months:
Check for corrosion.If first signs of corrosion show, apply new corrosion protec-
tion.
3.3. Packaging
Our products are protected by special packaging for transport when leaving the
factory.The packaging consists of environmentally friendly materials which can easily
be separated and recycled.We use the following packaging materials: wood,
cardboard, paper, and PE foil. For the disposal of the packaging material, we
recommend recycling and collection centres.

4.1. Mounting position
The actuators can be operated in any mounting position.
Air vent valve position
On leaving the factory, the air vent valve is not mounted but supplied separately. In
accordance with the mounting position of the multi-turn actuator, the air vent valve
must be mounted at position [1] All other bores [2] must be sealed using a screw
plug.
Figure 6: Position of air vent and screw plugs for different mounting positions
[1] Air vent valve
[2] Screw plug
Information For LOCA/DBE conditions, the actuator is specified to withstand a pressure of up to
6 bar.To ensure full operability under these conditions, the air vent must point upward
to allow air discharge via the air vent valve in case of overpressure within the actuator
housing.

5. Electrical connection
5.1. Basic information
Danger due to incorrect electrical connection
Failure to observe this warning can result in death, serious injury, or property damage.
→The electrical connection must be carried out exclusively by suitably qualified
personnel.
→Prior to connection, observe basic information contained in this chapter.
→After connection but prior to applying the voltage, observe the <Commissioning>
and <Test run> chapters.
Wiring diagram/terminal
plan The pertaining wiring diagram/terminal plan (both in German and English) is attached
to the device in a weather-proof bag, together with these operation instructions. It
can also be requested from AUMA (state order number, refer to name plate) or
downloaded directly from the Internet (http://www.auma.com).
Valve damage for connection without controls!
→NORM actuators require controls: Connect motor via controls only (reversing
contactor circuit).
→Observe the type of seating specified by the valve manufacturer.
→Observe wiring diagram.
Delay time Thedelaytimeis the time from thetripping of thelimitortorque switchesto the motor
power being switched off.To protect the valve and the actuator, we recommend a
delay time < 50 ms. Longer delay times are possible provided the operating time,
output drive type, valve type, and the type of installation are considered.We
recommend switching off the corresponding contactor directly by limit or torque
switch.
Protection on site For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches have to be provided by the customer.
The current value for respective sizing is derived from the current consumption of
the motor (refer to electrical data sheet).
Limit and torque
switches Limit and torque switches can be provided as single, tandem, or triple switches.Only
the same potential can be switched on the two circuits (NC/NO contact) of each
single switch. If different potentials are to be switched simultaneously, tandem
switches or triple switches are required.When using tandem/triple switches:
●For signalling use the leading contacts TSC1, TSO1, LSC1, LSO1.
●For switching off use the lagging contacts TSC, TSO, LSC, LSO.
