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.
The AUMATIC actuator controls are used to operate AUMA actuators and are supplied
ready for use.The controls may be mounted directly to the actuator or separately
on a wall bracket.
The functions of the AUMATIC controls include standard valve control in OPEN CLOSE duty, positioning, process control, logging of operating data, diagnostic
functions right through control via fieldbus.
Operation, setting, and display can be performed on site directly at the controls or
alternatively from REMOTE via a fieldbus interface.
On site 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 the COM-A C softw are (option), using a computer (laptop or PC). Depending on the version, the connection between computer and AUMATIC can be made with cable (infra-red interface) or without cable (Bluetooth interf ace) (not included in these instructions).
●
Intrusive version (control unit: electromechanical):
Limit and torque setting is performed via switches in the actuator.
●
Non-Intrusive version (control unit: electronic):
Limit and torque setting is performed via the controls, actuator and controls
housings do not have to be opened. For this purpose, the actuator is equipped
with an MWG (magnetic limit and torque transmitter), also supplying analogue
torque feedback signals/torque indication and analogue position feedback signals/position indication.

Wiring diagram/terminal
plan
Protection on site
The pertaining wiring diagram/terminal plan (in German and English language) is
attached to the device in a weather-proof bag, together with these operation
instructions. It can also be obtained from A UMA (state commission no ., refer to name
plate) or downloaded directly from the Internet (www.auma.com).
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 is derived from the current consumption of
the motor (refer to electrical data sheet) plus the current consumption of the controls.

Safety standards
Cable installation in ac-
cordance with EMC
If controls are mounted separately from actuator (controls on wall brack et): Consider
length and cross section of connecting cable when defining the protection required.
If the controls (electronics) are supplied externally with 24 V DC and DC motors (24
V DC, 48 V DC, 60 V DC, 110 V DC, 220 V DC) are used simultaneously, the 24 V
DC voltage supply for the controls should be ensured via the XK25/26 terminals,
separately from the power supply (U1, V1). In case of common supply using a single
cable (links from U1, V1 with XK25/26, for 24 V DC only !!!), short-term excess or
falling below the permissible voltage limits can be the consequence during s witching
(24 V DC +10 %/–10 %). Any possibly incoming operation commands are not
executed outside the admissible limit values.The controls briefly signal a fault
condition.
All externally connected devices shall comply with the relevant safety standards.
Signal and bus 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 bus 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 long par allel paths with cab les being either susceptible to interf erence or
interference sources.
●
For the connection of remote position transmitters, screened cables must be
used.

●
Use connecting cable with appropriate minimum rated temperature.
●
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.

Prior to installation, please note:
●
Connect maximum 32 devices to one segment.
●
If more devices are to be connected:
- Connect several segments using repeaters.
●
Respect a distance of minimum 20 cm between the bus cable and other cab les.
●
If possible, bus cables should be laid in a separate, conductive, and earthed
cable tray.
●
Make sure to avoid potential differences between the individual devices on the
bus (perform an equipotential earth bonding).
