I = MWG (Magnetic limit and torque transmitter)
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.

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 right through to
diagnostic functions.
Operation, setting, and display can be performed on site directly at the controls.
When set to local control, it is possible to
