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 actuatorsSA25.1-UW–SA 30.1-UW/SAR 25.1-UW –SAR 30.1-UW
are driven by an electric motor. Switching off in end positions may be either by limit
or torque seating. Actuator controls are required to operate or process the actuator
signals.
Actuator controls AC 01.2 actuator controls are used to operate AUMA actuators and are supplied
ready for use. In combination with multi-turn actuators SA 25.1-UW –SA
30.1-UW/SAR 25.1-UW –SAR 30.1-UW, they are mounted separately on a wall
bracket.For high nominal motor currents of the actuator, the switchgear of the actuator
controls additionally require a control box.
The functions of actuator controls include standard valve control in OPEN-CLOSE
duty, positioning, process control, logging of operating data right through to diagnostic
functions.AC 01.2
Local controls/
AUMA CDT Operation, setting, and display can be performed directly at the actuator controls.
When set to local control, it is possible to
●operate the actuator via the local controls (push buttons and display) and perform
settings (contents of these instructions).
●read in or out data or modify and save settings via AUMA CDT software (ac-
cessory), using a computer (laptop or PC).The connection between computer
and actuator controls is wireless via Bluetooth interface (not included in these
instructions).
Non-Intrusive Non-Intrusive version (control unit: electronic):
Limit and torque setting is performed via the controls, without removal of actuator or
actuator controls covers.For this purpose, the actuator is equipped with an MWG
(magnetic limit and torque transmitter), also capable to supply analogue torque
feedback signals/torque indication and analogue position feedback signals/position
indication at the actuator controls output.

connections All input signals (control inputs) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.
Safety standards Safety measures and safety equipment must comply with the respectively valid
national on site specifications.All externally connected devices shall comply with
the relevant safety standards for the place of installation.
Connecting cables ●We recommend using connecting cables and connecting terminals according
to rated current (IN) (refer to motor name plate or electrical data sheet).
●For device insulation, appropriate (voltage-proof) cables must be used.Specify
cables for the highest occurring rated voltage.
●Use connecting cable with appropriate minimum rated temperature.
●For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
●For the connection of position transmitters, screened cables must be used.
Cable installation in ac-
cordance with EMC Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
●Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
●The interference immunity of signal and fieldbus cables increases if the cables
are laid close to the earth potential.
●If possible, avoid laying long cables and make sure that they are installed in
areas being subject to low interference.
●Avoid parallel paths with little cable distance of cables being either susceptible
to interference or interference sources.

Wall bracket
Actuatorcontrols are alwaysmounted separatelyfrom the actuatoron a wall bracket,
outside the flooded area.
When mounting actuator controls outside the flooded area but below water level, we
recommend using the DS intermediate double sealed frame between wall bracket
and plug/socket connector.

For actuators with high nominal motor current (AUMA power class switchgear from
category A4), a control box is additionally required.Switchgear (reversing contactors)
will then be installed in the control box and not within the actuator controls. Control
box is mounted separately on the wall.
Danger of short-circuit!
In case of incorrect assembly, water may ingress the control box by flowing along
the cable.
→Mount control box outside the flooded area above the maximum possible water
level.
For the power supply cable, fuses have to be provided for short-circuit protection by
the customer.The fuses have to be adapted to the cross section of the cable, the
thermal overload relay in the control box, the switch contacts and the motor data
(refer to motor name plate).

Connecting cables
●Connecting cables must be protected against damage and securely fixed.The
plant operator or the contractor are responsible for providing the required cable
protection.
●The permissible cable length between actuator controls on wall bracket and
the actuator amounts to 100 m maximum.
●Exclusively use AUMA “LSW”cable sets as connecting cables “LSW and LS”!

●For LSW 69/76 cable sets, the plug/socket connector must be opened at wall
bracket level and the cables must be connected to the pin carrier according to
the terminal plan.Appropriate crimping pliers are required for orderly crimping.
Suitable pliers are available at AUMA (art. no. K007.979).

●When connecting, make sure that the shield of both connecting cables is suffi-
ciently overlapping (approx.2 mm over the O-ring) the contact socket of the
cable gland.
1) For connection with cable set LSW 76 (in combination with wall bracket) only one cable (hybrid
cable) is available at plug/socket connector.The motor cable is then directly led from the actuator
vis LS 36 to the control box.
