1. Safety instructions
1.1. Basic information on safety
Standards/directives AUMA products are designed and manufactured in compliance with recognized
standards and directives.
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.
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 exclusively by suitably qualified personnel having been authorized 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 recognized rules
regarding occupational health and safety.
Work performed in potentially explosive atmospheres is subject to special regulations
which have to be observed.The end user or contractor of the plant is responsible
for respect and conformance to 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 recognized rules for occupational health and safety.
●Observe the national regulations.
●During operation, the housing warms up and surface temperatures > 140 °F
(60 °C) may occur.To prevent possible burns, we recommend checking the
surface temperature using an appropriate thermometer and wearing protective
gloves, if required, prior to working on the device.
Protective measures The end user or the contractor is 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 consent of the manufacturer.

AUMA power class for
switchgear The switchgear used in the actuator controls (reversing contactors/thyristors) are
classified according to AUMA power classes (e.g.A1, B1, ....).The power class
defines the max. permissible rated power (of the motor) the switchgear has been
designed for.The rated power (nominal power) of the actuator motor is indicated in
HP [kW] on the motor name tag. For the assignment of the AUMA power classes to
the nominal power of the motor types, refer to the separate electrical data sheets.

2.2. Short description
Multi-turn actuator Definition in compliance with EN ISO 5210:
A multi-turn actuator is an actuator which transmits to the valve a torque for at least
one full revolution.It is capable of withstanding thrust.
AUMA multi-turn actuators 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. Controls are required to operate or process the actuator signals.
Actuator controls AUMA MATIC actuator controls are used to operate AUMA actuators and are supplied
ready for use.The controls can be mounted directly to the actuator but also separately
on a wall bracket.The functions of the AUMA MATIC controls include standard valve
control in OPEN - CLOSE duty, position indications and different signals right through
to position control (option).
Local controls Operation (via push buttons), setting and indication can be performed directly at the
controls (contents of these instructions).

3.1. Transport
For transport to place of installation, use sturdy packaging.
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:Attachropes or hooksforthe purposeoflifting
by hoist only to the gearbox using eyebolts and NOT to the actuator.
→Actuators mounted to controls: Attach ropes or hooks for the purpose of lifting
by hoist only to the actuator and NOT to the controls.
→Respect total weight of combination (actuator, actuator controls, gearbox, valve)
3.2. Storage
Danger of corrosion due to inappropriate storage!
→Store in a well-ventilated, dry room.
→Protect against floor dampness by storage on a shelf or on a wooden pallet.
→Cover to protect against dust and dirt.
→Apply suitable corrosion protection agent to uncoated surfaces.
Damages due to excessively low storage temperatures!
→AUMA MATIC actuator controls may NOT be stored below –40 °F (–40 °C).
Long-term storage If the device must be stored for a long period (more than 6 months) the following
points must be observed in addition:
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 the transport ex works.The
packagingconsists of environmentallyfriendly materialswhich can easily beseparated
and recycled.We use the following packaging materials: wood, cardboard, paper,

→Do not jam cover during fitting.
1. Loosen screws and remove local controls.
2. Loosen 3 screws of the board, turn board to the new position and tighten the
screws.
3. Check whether O-ring is in good condition, correctly insert O-ring.
4. Turn local controls into new position and re-place.
Cable damage due to twisting or pinching!
Risk of functional failures.
→Turn local controls by a maximum of 180°.
→Carefully assemble local controls to avoid pinching the cables.
5. Fasten screws evenly crosswise.

5.1. Basic information
Electric shock due to presence of hazardous voltage!
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 is in the cover of the electrical connection.
The operation manual is attached to the device in a weather-proof bag.
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 values for respective sizing are derived from the current consumption
of the motor (refer to electrical data sheet) plus the current consumption of the
actuator controls.
Table 6:
Current consumption controls
Max. current consumptionMains voltage
575 mA100 to 120 V AC (±10 %)
275 mA208 to 240 V AC (±10 %)
160 mA380 to 500 V AC (±10 %)
500 mA24 V DC (+20 %/–15 %) and AC Motor
Table 7:
Maximum permissible protection
Max. protectionRated powerSwitchgear
16 A (gL/gG)up to 1.5 kWReversing contactor A1
32 A (gL/gG)up to 7.5 kWReversing contactor A2
63 A (gL/gG)up to 11 kWReversing contactor A3
If controls are mounted separately from actuator (controls on wall bracket):Consider
length and cross section of connecting cable when defining the protection required.
Power supply for the
controls (electronics) If the controls (electronics) are supplied externally with 24 V DC, the power supply
is smoothed via an internal 1,000 µF capacitor.When selecting a power supply, care
must be taken to consider the capacitor inrush current upon powering the unit up.
Safety standards All externally connected devices shall comply with the relevant safety standards.
Type of current, mains
voltage and mains fre-
quency
Type of current, mains voltage and mains frequency must match the data on the
motor name tag.
