2.1. 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.
Figure 1: Example, Multi-turn actuator SAEx 25.1
AUMA multi-turn actuators SAEx 25.1 – SAEx 40.1/SAREx 25.1 – SAREx 30.1 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.
Actuator controls
ACExC 01.2 actuator controls are used to operate AUMA actuators and are supplied
ready for use. In combination with multi-turn actuators SAEx 25.1 – SAEx 40.1/SAREx
25.1 – SAREx 30.1, 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.ACExC 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).
