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
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.
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).
●
read in or out data or modify and save settings via the AUMA ToolSuite 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).
