IQ3 Pro Innovations
When connected to an actuator, the dashboard screen allows access to the app’s functions. From here, users can retrieve data logs, manually configure the actuator, complete a valve setup using a guided wizard or even emulate the Bluetooth® setting tool. Detailed status information is displayed in a prominent position for easy access.
Intelligent Asset Management (iAM)
Rotork's Intelligent Asset Management (iAM) is a cloud-based asset management system for intelligent actuators and the flow control equipment they operate.
The system helps customers reduce unplanned downtime (and the poor performance, reduced output yields and reputational damage that can accompany downtime) by using analytics based on data taken from the data logs within intelligent actuators to create a maintenance plan.
Data can be downloaded wirelessly with the Rotork Bluetooth® Setting Tool Pro, Rotork app or to a PC and analysed using the Rotork Insight 2 software. The Insight 2 programme allows the user full access to configuration and valve performance analysis. Rotork Insight 2 facilitates the review, configuration and analysis of set-up configuration and data logger information for Rotork Bluetooth® enabled actuators. The visually interactive application is intuitive with clear menus making it a simple and fast process.
Bluetooth® Communications Interface
IQ3 Pro actuators are set up using its partner Bluetooth® Setting Tool (or Rotork app). Bluetooth® connectivity allows easier use without direct-line of sight and over greater distances, however security has to match. This is achieved by the initial "pairing" of tool and actuator being carried out by a single infrared transaction after which a Bluetooth® wireless connection automatically takes over. The Bluetooth® connection has 4 levels of configurable security. Configuration changes are password protected and the actuator is immune to connection by non-Rotork devices or programmes. Rotork actuators include an onboard data logger, which captures valve, actuator, control signal operation, service alarms and status data which can be viewed locally on the display or downloaded to a PC using Insight 2.
The dual stacked display allows large segment character position displays down to -50 °C while the matrix display provides detailed setting, status and diagnostic (graphical and textual) multi-lingual screens. The display is backlit to provide excellent contrast even in the brightest ambient light conditions and is protected by a toughened glass window. An optional protective clip-in cover is available where high UV levels or abrasive conditions are present. The position indication is shown to one decimal place.
Compact Double-Sealed Enclosure
The Rotork double-sealed design permanently ensures the protection of internal components - even during site wiring - by separating them from the cable gland and terminal compartment with a watertight terminal block.
Enhanced Reliability using an Absolute Encoder (Multi-turn Variants)
Reliable valve position sensing is critical. Using the latest technology and after several years of testing, the patented Rotork IQ absolute encoder is contactless, has only four active parts, can measure up to 8,000 output turns with a resolution of 7.5° and has redundancy and self checking built in. Unlike existing absolute encoder designs, this technological breakthrough increases position sensing reliability while providing zero-power position measurement.
Intelligent Battery Management
The on-board battery provides power for local and remote indication when the main actuator supply is unavailable. The battery also provides power to enable actuator settings to be made using the Rotork Bluetooth® Setting Tool Pro or the Rotork app; commissioning can take place at premises without power or the right voltage, or after installation but before site cabling is completed. This also enables the datalogger to be fully operational without mains power.
Plug and Socket
IQ3 Pro range actuators can be supplied with a fully engineered plug and socket interface to provide fast connection and disconnection in the field. Plug and socket facilitates field wiring in advance to improve commissioning speed and efficiency. The IQ plug and socket option maintains the IP68 rating (7 m for 72 hours) and is certified for use in hazardous areas.
Human Machine Interface (HMI) includes a large high contrast dual-stacked display, local controls, Bluetooth® wireless technology, Status indication and an optional environmental shield. Non-intrusive local control guaranteed with the use of robust magnetic hall-effect sensors.
Secure Local Controls
Padlockable local/stop/remote selector switch and Open/Close switch operate hall effect sensors, avoiding penetrating shafts which would require sealing for environmental protection.
Incorporating a direct drive or geared handwheel, sized for effective manual operation of the valve, with centre-column bearing enhancements for improved centre-column support. Handwheel drive is independent of the motor drive and is selected with a lockable hand/auto lever for safe operation even when the motor is running.
Thrust Base (Multi-turn Variants)
For all sizes, the cartridge styled thrust and non-thrust base types are separate to the gearcase facilitating easy installation. Should the actuator be removed, the base can be left on the valve to maintain its position.
Watertight, Dust tight and Explosionproof
The IQ enclosure is rated IP68 (7 m for 72 hours), NEMA 4/4X/6. It is completely watertight, dust tight and does not "breathe". Explosionproof certified actuators share the same enclosure. Customised paint finishes and fire protection coatings available.
Remote Hand Station
The Remote Hand Station is a bolt-on extension of the IQ3 range. Mounted away from areas that are hazardous, inconvenient or unpleasant for humans to operate, they allow full remote control, access and configuration in a safe manner.
Multiple Fieldbus Connectivity
Rotork actuators are compatible with the most popular industry standard Fieldbus systems via network cards that are fitted in the main electronics enclosure. Additionally, the IQ3 Pro Range is fully compatible with Rotork's own proprietary 2-wire network system, Pakscan™ and Pakscan™ Wireless.
