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.
Figure 2: Actuator controls and control box

AUMA power class for
switchgear The switchgear used in the actuator controls (reversing contactors/thyristors) are
classified according to AUMA power classes (e.g.A1, B1, ....).The power class
defines the max. permissible rated power (of the motor) the switchgear has been
designed for.The rated power (nominal power) of the actuator motor is indicated in
kW on the motor name plate.For the assignment of the AUMA power classes to the
nominal power of the motor types, refer to the separate electrical data sheets.
For switchgear without assignment to any power classes, the actuator controls name
plate does not indicate the power class but the max. rated power in kW.
