Quantum leap for AUMA CDT software

Added - 12.01.2021

A new, entirely redesigned version of AUMA Actuators Limited’s proven AUMA Commissioning and Diagnostic Tool (CDT) is now available. The new AUMA CDT version 2020 allows fast and easy setup, operation and diagnostics of AUMA actuators using a Windows laptop.

The modern user interface and comprehensive functions of AUMA CDT help to save time and cost during commissioning, maintenance and troubleshooting. Originally designed for AUMA’s own service experts, the high-performance software tool also offers most functions to registered users. These include setting of tripping torques and end positions, modification of actuator parameters and remote actuator control. The new version also allows users to create service requests and to upload snapshot files with actuator data to the AUMA Cloud for detailed analysis.

Profibus and Modbus master functions are available for control system integration. Comprehensive diagnostic functions, such as a powerful process data monitor and an I/O interface simulator, reduce service times.

The new version of AUMA CDT benefits from a fully optimised communication protocol for Bluetooth connection to the actuator, resulting in considerably faster data transmission. A new centralised AUMA user management system improves protection against unauthorised access.

AUMA CDT supports SA and SQ actuator series with AC 01.2 actuator controls as well as SGx and SVx actuator series. The new version also supports the new PROFOX actuators.

The redesign of the AUMA CDT software underpins the company’s continuous commitment to provide users with the best support tools possible for operating AUMA actuators.

A new version of the AUMA Assistant App for smartphones and tablets is also available. Version 4.0 also provides fast Bluetooth communication and supports AUMA PROFOX actuators.

AUMA TIGRON: The new actuator for the oil and gas industry

Added - 25.11.2020

AUMA’s new TIGRON actuators are designed to meet the exacting requirements of the global oil and gas industry. Building on AUMA’s more than 50 years of experience as a leading electric actuator manufacturer, TIGRON combines the highest level of explosion protection, robust design, outstanding ease of operation, and the latest trends in digitalisation. The versatile all-rounder provides safe and reliable valve automation across all application sectors, including oil and gas production, pipelines, tank farms and refineries.

Safe and robust
TIGRON actuators are ATEX and IECEx certified for the highest gas group IIC, which includes the highly flammable hydrogen. Other approvals will follow. The actuators are designed to withstand the harshest environmental conditions, covering a particularly wide temperature range from –65 °C to +75 °C. IP68 enclosure protection and AUMA’s extremely resistant powder coating protect effectively against tropical downpours, ocean spray and desert sandstorms.
For installation in hard-to-reach locations or where vibration is a problem, the controls can be mounted separately, up to 100 m away from the actuator. TIGRON actuators will also be available in SIL versions.

Powerful electronics, innovative sensor systems and a wide variety of interfaces ensure that TIGRON is future-proof as digitalisation advances. Data upload to the AUMA Cloud facilitates predictive maintenance. Low standby power consumption reduces the actuator’s carbon footprint and decreases operating costs.

Easy to use
Excellent usability is another feature of TIGRON actuators. Particularly striking are the large display and the robust Combi-Switch, which can be operated easily even when wearing gloves. An on-board commissioning assistant guides the operator safely through the setting procedure. TIGRON actuators provide non-intrusive setup without requiring additional tools for commissioning.

TIGRON actuators work with all types of valves. As a multi-turn actuator, TIGRON is ideal for gate valve automation. It is available in six sizes, providing torques from 10 Nm up to 1,000 Nm. Higher torques can be achieved in combination with multi-turn gearboxes. For ball, butterfly and globe valve automation, TIGRON actuators are combined with part-turn gearboxes or linear thrust units. The smart actuators are suitable for the most challenging automation tasks, such as high-precision operation of control valves or choke valves.

“Our new TIGRON is robust and reliable, easy to use, and a perfect match to all the requirements of the oil and gas industry,” says Kai Ewald, Head of Sales Oil & Gas at AUMA. “TIGRON actuators help plant operators enhance their efficiency and strengthen their market position. With TIGRON, they are well equipped for modern plant automation, today and tomorrow.”

Covid-19 Preparedness and contingency planning UPDATE

Added - 16.11.2020

We are continuing with our remote operating structure with all our staff who can work from home based at home and away from our office/warehouse/workshop in Clevedon. 

Our telephone system remains the same and you can call us via the main switchboard number (01275 871141). It is also possible to call sales directly on 01275 335626 or service on 01275 335629. All our email addresses remain unchanged and sales can be contacted on with service available on ; you can also use direct dial numbers and mobile numbers as before.

We have established our teams for local UK assembly responding to customers’ critical spares, repairs and replacement parts. These teams can be mobilised as necessary to ensure your needs are safely met. We also have our regionally based field service teams and our ACE (AUMA Certified Engineering) Partners’ field service teams located conveniently close to our customers enabling a service escalation from phone support to site service with replacements if required in all locations across the UK and Ireland.

We also have access to local supply partners for machining of adaptions which allows the replacement of non-AUMA actuators should that be required to keep our customers’ critical systems up and running.

Our German parent company factory is running a dual shift system in both office staff and factory helping to mitigate the risk of personnel impact. Our supply chain is relatively short with 95% of our product supply from our parent company in Germany. In turn, our parent company sources approximately 80% from Europe. We do all our own machining of castings and mechanical components including gearboxes. We also manufacture our own motors and printed circuit boards. 

We have managed with this structure from March to October with no impact on our ability to support our customers; we therefore anticipate a worst case of 90% availability of our workforce at any point in time, based on the fact that we will be operating with over 75% usefully working from home and the field service teams operating in several “bubbles”. There may be an effect on service and product lead times if we drop in capacity but we will be doing everything we can to support our customers whilst following Government advice and keeping our staff and customers safe.

Our utility customers have written to us identifying AUMA as a critical support partner allowing more flexibility for movement of goods and people; our implemented interim structure will allow us to take advantage of this.

We continue to hold about four months’ inventory with a two month lead time for replenishment from our parent company factory in Germany.

We will be following all Public Health England (PHE) and Government advice and will do everything to support our suppliers, staff and customers through what continues to be a tough period for many.

Variable Speed Actuation Opens up New Application Opportunities - Paul Hopkins, Managing Director, AUMA UK

Added - 13.10.2020

Valve actuators are often misconceived as relatively simple devices that perform a straightforward function. There are, however, significant opportunities and substantial savings available to the control engineer through the smart deployment of actuator technologies.

There are two distinct functions that a valve actuator performs – the ‘intelligence’ of managing digital or analogue control signals and feedback loops, and the ‘brute force’ to open and close a variety of different valve types. At AUMA we separate the ‘intelligence’ and ‘brute force’ by taking a modular approach to our actuator construction. This provides an enhanced choice of actuator configuration for our customers, dependent on the end application.

Analogue or digital control heads or, indeed, no control head, can be connected to a range of different drive units through AUMA’s common interface. The symmetrical connection design enables the head to be connected in one of four different orientations. In addition, the basic actuator can be built on site in up to 64 different configurations. The control head can also be connected through an umbilical cable of up to 100m length, so the two components can be separated for safety or operational convenience, for example in underground or underwater applications.

Sophisticated Control
While fixed speed open/close functionality satisfies the majority of valve actuation situations, there are opportunities available from more sophisticated variable speed actuators. Water hammer can be a significant issue in many applications. Valve seats suffer if they are driven hard to their end positions whenever the valve is closed. A variable speed actuator, such as the AUMA SIPOS SEVEN, gives the control engineer the opportunity to specify the speed of actuation at different points in the cycle. The usual way that this is employed is to move the valve quickly through the majority of its cycle, slowing it down as it nears the close position, alleviating water hammer problems and extending the life of the valve seat. For emergency situations a ‘fast close’ speed can be specified.

AUMA’s SIPOS SEVEN also has a multiple speed/set point capability. This can be used to provide near linear performance from low cost non-linear valves. A further interesting benefit of a variable speed system with a clever built-in inverter, like SIPOS SEVEN, is that it provides high start-up torque without peak start-up current and low overall power. What that means in practice is that cables, even on long runs, can be specified for the nominal currents and remote, even solar powered applications become possible.

Reducing system costs at Control Design stage
The valve actuator, in almost all cases, arrives on site as part of the valve package, and may only be considered as a means to an end. However, the actuator should also be considered as part of the site control system. Other sensors within the process, such as level or flow monitors, can make use of the actuator’s in-built A/D conversion and industrial Ethernet connectivity to feed data back to the central control system. AUMA’s AC .2 actuator controls optionally include PROFINET for transfer rates up to 100Mbit/s, with simplified commissioning through automatic address assignment.

The modular approach also provides another interesting time and cost-saving opportunity. There is no need, technically, for the entire actuator to be supplied to the valve manufacturer or directly to site. It is perfectly feasible for the valve supplier to receive the mechanical components, the gear box etc (what AUMA refer to as the ‘Norm’), while the control engineers take delivery of the control unit. That way, configuration and programming can be undertaken before the two parts of the actuator are reunited on site. Valve assemblies can be delivered on skids and installation work on site is significantly reduced. 

AUMA has supported these new opportunities with a multi-level training programme, ACE, which certificates technicians and engineers based within valve manufacturers, systems integrators or on-site, at the level appropriate to their task – Level 1 for correct installation and configuration, typically at the valve supplier, and Levels 2 and 3 covering more detail, including commissioning, configuration and system integration.
