ACVExC 01.2 Non-Intrusive Modbus RTU Identification

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 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.
For variable speed multi-turn actuators SAVEx 07.2 –SAVEx 16.2/SARVEx 07.2 –
SARVEx 16.2, the actuator speed is modified by means of a frequency converter in
the actuator controls.
Actuator controls ACVExC 01.2 actuator controls are used to operate AUMA actuators and are supplied
ready for use.
The functions of the actuator controls include standard valve control in OPEN-CLOSE
duty, positioning, process control, logging of operating data, diagnostic functions
right through control via various interfaces (e.g. fieldbus, Ethernet and HART).
Local controls/
AUMA software Operation, setting, and display can be either performed directly at actuator controls
or alternatively from Remote via binary input signals, or using another interface.
The following options are available at the actuator controls in local operation:
●The actuator can be operated via the push buttons of the local controls or set-
tingscanbe made intheactuator controls menu.Thedisplayshows information
on the actuator as well as menu settings (contents of these instructions).
●Using the AUMA CDT software for Windows-based notebooks or the AUMA
Assistant App for Android-based devices, data can be uploaded and read
whereassettingscanbemodified and stored.Theconnectionbetweencomputer
and actuator controls is wireless via Bluetooth interface (not included in these
instructions). AUMA CDT software can be downloaded free of charge from our
website www.auma.com.
Intrusive - Non-Intrusive ●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, without removal of actu-
ator or actuator controls covers.For this purpose, the actuator is equipped with
anMWG (magnetic limit and torque transmitter),also capableto supply analogue
torque feedback signals/torque indication and analogue position feedback sig-
nals/position indication at the actuator controls output.
