Auma Actuator Controls and Actuator Products

Once power supply has been established, actuators equipped with integral controls can be operated via the operation elements on the local controls. The controls are perfectly adapted to the actuator.

The actuator can be completely set locally, without requiring direct connection to the DCS. Only operation commands and feedback signals are exchanged between the control system and the actuator. Motor switching is performed within the device and virtually without delay.

AUMA actuators are available with AM or AC integral controls.

 

AUMA AC and ACV

Description & Features

AC controls are your perfect solution if the application requires self-adapting control functions, data logging, confi gurable interface or if valve and actuator are to be integrated into a Plant Asset Management System due to advanced diagnostic functions.

AC controls are equipped with a parallel interface for free configuration and/or interfaces to fi eldbus systems as used within process automation.

The diagnostic functions comprise a time-stamped event report, torque characteristics logging, continuous recording of temperatures and vibration within the actuator and, furthermore, counting the number of starts and motor running times.

Further to the basic functions, AC controls offer a number of options to meet special demands. These include torque by-pass to unseat valves if tightly seated or functions for extending operating times to avoid water hammer within pipelines.

With the development of the AC 01.2, particular emphasis was laid on user-friendliness and the ease of integration of actuators into the DCS.

The large graphic display is used to perform menu-controlled programming of the controls, optionally using AUMA CDT via wireless Bluetooth connection. For fieldbus connections, AC programming can be performed from the control room.

AUMA AC SIL and ACEx SIL

Description & Features

For highest requirements on functional safety (SIL) in compliance with IEC 61508 / IEC 61511, AUMA offer special actuator controls in AC.2-SIL version. They have been certified by TÜV with SA.2 / SAEx.2 multi-turn actuators in compliance with the latest (ed. 2) and most demanding edition of the IEC 61508 standard, and may be used up to SIL 2, in redundant systems (e.g. “1oo2”) up to SIL 3. Controls can be supplied with the safe functions commonly used with actuators. In addition, one of the two ESD functions (Safe OPENING/CLOSING) can be combined with the Safe STOP function. Different types of seating in end position can be selected for the ESD function.

 

Since AC.2-SIL/ACEx.2-SIL controls are based on AC.2/ACEx.2 controls while the safety function is implemented by means of an additional PCB, regular convenience, control and monitoring functions of the AC.2 / ACEx.2 controls can be used during normal operation.

AUMA AM

Description & Features

 

AM controls with simple design and defined features is the perfect choice when using parallel signal transmission and if a relatively low number of feedback signals is required.

Few parameters need to be defi ned via sliding switches during commissioning, e.g. type of seating in end positions.

Actuator control is made via operation commands OPEN, STOP, CLOSE.

Reaching an end position and collective fault signals are reported back to the DCS as feedback signals. These signals are visually displayed at the local controls via the indication lights. As an option, the valve position can be transmitted as 0/4 – 20 mA signal to the DCS.

AUMA Explosion-proof version- AM

Description & Features

Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition source. Their constructive measures prevent the occurrence of ignition sparks or hot surfaces.

AUMA Explosion-proof versions AC

Description & Features

Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition source. Their constructive measures prevent the occurrence of ignition sparks or hot surfaces.

Certification is performed in close collaboration with national and international certification bodies.

With the ACExC a control with integral local controls is available for the multi-turn actuators SAEx/SAREx 07.2 – 16.2 and the part-turn actuators SQEx/SQREx 05.2 – 14.2.
