Advanced Design Features

CMA Advanced Design Features

The CMA encompasses advanced design in a compact, robust and reliable package.

The brushless DC motor technology provides high dynamic performance with a maintenance free, high endurance drive train.

Thrust or torque is instantly delivered to the valve to provide smooth operation without any stick/slip effect to disrupt the process variable. The sturdy mechanical drive train eliminates the unwanted movements associated with spring diaphragm actuators.

The CMA provides consistent and precise performance regardless of changing process conditions.

Control without the need for instrument air eliminates the capital costs, running costs and maintenance costs associated with air supplies.

Constantly changing process demands are no problem to the continuous modulating capability of the CMA.

Compact and flexible, the CMA range can be mounted on any type or make of valve including all the leading control valve makers’ products.

Other applications such as pump stroke control are perfect for the CMA with its high accuracy, especially for applications requiring hazardous area certifications.

Advanced Engineering

1 Encoder Technology

The CMA utilizes absolute encoder technology where a unique digital code corresponds to the angular position (CMQ), stroke length (CML) or rotary (CMR) position of the actuator.

To achieve high resolution, the position sensor location eliminates any backlash effect in the gearing. The sensor is a 12-bit rotary magnetic encoder, fitted at the output gear stages, removing any internal backlash effect that may exist in the drive train.

2 User Interface

Two relays can be programmed to close upon reaching a desired position or any other available fault condition among the programmable options.

3 DC Brushless Motor

The CMA uses a high efficiency, continuous rated, brushless DC motor. This allows maintenance-free operation even with continuous unrestricted modulation duty.

CMLLinear Actuator

Programmable User Interface

The CMA LCD display is a 6-character, single line display. Two graphic symbols are provided for notification of alarm conditions. The menu style is an intuitive common tree structure similar in function to the menu system used on PCs.

4 Hand Drive

A hand drive mechanism is provided as standard for all CMA actuators to allow manual operation of the valve. Pressing down on the hand-knob shaft allows it to engage a gear in the upper section of the drive train. Releasing causes the spring to disengage the gear.

5 Geartrain

The simple yet durable high efficiency spur gear drive is lubricated for life. It has proven high reliability.

6 Anti Back-Drive Mechanism

The CMA standard build is capable of resisting any back drive from the load, up to 125% of the rated thrust or torque of the actuator.

7 Output Drive

The CMQ and CMR base conforms to MSS SP-101 or ISO 5211. CML may be adapted to suit individual valves.

HART®

HART (Highway Addressable Remote Transducer) is a process control communication protocol based upon the Bell 202 telephone communication standard and uses the FSK (frequency shift keying) principle. The signal consists of two parts, the analogue 4-20 mA current loop and a superimposed digital variable frequency signal.

Traditionally the 4-20 mA loop is used for control and the superimposed digital signal for feedback, diagnostics and configuration. Configuration and feedback using the HART digital signal can be achieved using the host connected to the actuator to select the parameters required. The majority of the user configurable settings can be made over the HART communication protocol.

• Up to 63 devices on each network

• Electronic device description (DD) files

• HART 7 compatible.

Foundation FieldbusTM

Foundation Fieldbus has become widely accepted for use in process control systems. It’s primary feature is the ability to distribute control away from the central DCS. The Rotork Foundation Fieldbus interface card connects directly onto the standard Foundation H1 bus system. The function blocks embedded in the module cover the control and monitoring of the valve and actuator.

Using the certified Device Description files the FF card is simple and easy to use. The ability to report extensive actuator feedback within a single input block as well as system diagnostic information makes Rotork the first choice for use with a Foundation Fieldbus system.

• Foundation ITK inter-operability certified

• Fully compliant with IEC61158-2 standard

• Includes Link Master and LAS capability

• Independent HIST approval by major DCS vendors

• Full H1 Field capability.

Profibus®

Profibus is a leading international network protocol for high speed data communications in industrial automation and control. The Rotork Profibus DP interface card provides comprehensive control and feedback data about the valve and actuator using DP-V0 cyclic communications whilst extended actuator diagnostics and configuration is included in the DP-V1 acyclic data supported by this module.

EDD and DTM files allow the Rotork device to be incorporated into asset management systems giving access to performance critical parameters, whilst the independently certified GSD file guarantees device interoperability. Rotork provide an optional switch disconnect module allowing for ease of installation and have multiple configuration options within the GSD file to enable a choice of data collection.

• RS485 Profibus DP V0 and V1 compliant

• Single and Dual Redundant options

• Fully meets IEC61158-3 standard

• Profibus PNO certified

• Supports speeds up to 1.5 Mbit/s.

Modbus®

Modbus remains the most popular process communication protocol in use today with the widest acceptance and highest number of applied systems of any automation protocol. Rotork’s Modbus interface card allows actuators to be connected to a 2-wire RS485 network for direct communication to a PLC or DCS using Modbus RTU protocol.

The resulting network is able to monitor and control the connected actuator. As the Modbus protocol is so simple the system engineer has full control over the data flow on the highway and the information to be collected and controls implemented. There are no complications with device description files or special programming tools required when setting up a Modbus system.

• RS485 2-wire RTU communication

• International open standard

• Single and Dual redundant options

• Integral Repeater modules included where necessary

• Up to 115 kbps.

Rotork Site Services division, bringing together project, service and retrofit activities, is active in 47 service centres in over 20 countries, with agents providing support services in a further 55 countries. The total number of expert technicians supporting Rotork customers is well over 1,000.

The division provides services in maintenance, management and the upgrading of installed actuation assets in order to fully support and satisfy the increasing demands for these activities from customers throughout the world. The services are tailored to meet customers’ specific needs, encompassing the following:

Emergency and Planned Service

Available for all types of actuator, in all areas (including hazardous environments). Some customers require guaranteed emergency response times, others require planned response for all types of actuator work, including installation, commissioning, upgrading, connection and installation of bus communication systems, troubleshooting and repair of damaged or deteriorating assets.

Actuator Overhauls

After a long service life customers may prefer their actuators to be completely overhauled rather than replacing them with new ones. In our workshops we completely strip and rebuild actuators, returning them to their original state.

Health Checks

Some customers lack detailed information on their assets, making it difficult to prioritise maintenance and replacement investment. We can carry out a detailed and intrusive inspection of the actuators and combine this with build data from our own databases to give customers a holistic view of their assets.

Retrofitting actuators to existing valves

We have extensive experience in fitting actuators to valves, penstocks and dampers that are already installed as part of existing plant. Whether customers are replacing obsolete actuators, changing power sources or motorising manual valves, we offer a tailor made solution to meet customers’ specific requirements.

Shutdown Outages

We can support customers in making sure that all their actuators are fully operational and that they meet tight shutdown deadlines. For example some power stations look for us to remove and overhaul in our workshops over 200 actuators when taking a unit out for maintenance. We do this, reinstall and commission the actuators and, where requested, carry out additional actuation projects simultaneously to ensure that customers make the most of their plant shutdown time.

Preventative Maintenance

We provide regular scheduled maintenance to enhance the integrity of actuators and their associated valves. This service is typically sought by customers looking to maximise the up-time of their plant.

Factory fitting of actuators to new valves

The careful assembly of valve and actuator is critical to ensure that an automated valve performs correctly and reliably. Whilst this service is often carried out by valve manufacturers, if there is a need we can provide this serrvice.

Extended scope projects

This is a growing requirement and some of our service teams have the wide range of skills necessary to offer a “one-stop-shop” to automate part or all of a customer’s process. Our capabilities cover all of the installation phases (scoping, design, procurement, manufacturing, installation, commissioning) on the broad scopes that typically surround actuation projects.
