2.2 Short description
Part-turn actuator Definition in compliance with EN ISO 5211:
A part-turn actuator is an actuator which transmits a torque to the valve for less than
one full revolution.It need not be capable of withstanding thrust.
AUMA part-turn actuators are driven by an electric motor. A handwheel is provided
for manual operation.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 TheAUMATIC actuatorcontrols are usedto operate AUMA actuatorsandare 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.
Local controls/AUMA
ToolSuite Operation, setting, and display can be performed directly at the controls or
alternatively from REMOTE via a fieldbus interface.
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).
●readin orout dataormodify andsave settings viathe AUMAToolSuite software
(option), using a computer (laptop or PC).The connection between computer
and AUMATIC is wireless via Bluetooth interface (not included in these instruc-
tions).
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, 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 si-
gnals/position indication.
