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.

2.2. Short description
Multi-turn actuator
Definition in compliance with EN ISO 5210:
A multi-turn actuator is an actuator which transmits to the valve a torque 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. Controls are required to operate or process the actuator signals.
Actuator controls
The AUMA MATIC actuator controls are used to operate AUMA actuators and are
supplied ready for use.The controls can be mounted directly to the actuator but also
separately on a wall bracket.The functions of the AUMA MATIC controls include
standard valve control in OPEN - CLOSE duty, position indications and different
signals right through to position control.
Local controls
Operation (via push buttons), setting and indication can be performed directly at the
controls (contents of these instructions).
