Convenient Debugging:

The IZQ can be adjusted simply, safely, and quickly using a non-invasive infrared setting tool. Using the "plug-and-play" IZQ setting tool professional version, you can access and adjust the actuator settings, such as torque value, limit, control, and display functions. The unique intrinsically safe setting tool allows for non-invasive setting of the actuator in any environment, regardless of whether the power supply is available.

Simple Troubleshooting:

A large-scale digital position display allows for remote real-time display of valve position. In addition, an easy-to-read, backlit display provides valve operating status, control and actuator status, and fault information. It is convenient for users to understand the current working status of the actuator. Using the Ql setting tool professional version, the torque distribution and actuator configuration of the relative position can be accessed during debugging, adjustment, or local valve monitoring. The built-in data recorder records operation, alarms, and valve torque distribution data, providing valuable information on operating status and operating conditions.

IZQ Actuator Display Characteristics:

Actuator Display

The IZQ includes an LCD dot matrix display specifically designed for actuator display. The actuator works normally under normal operating temperature conditions. The large screen with backlight allows users to clearly see the valve position indication information under various lighting conditions.

The display shows in real time the command information from the central control room, the valve position, the operating status of the actuator, and the torque and alarm messages during the operation. Using the setting tool, the display can be changed from position mode to setting mode, making it easy for users to view, adjust

and change the actuator parameter settings. The display unit also provides six LED indicators to indicate forward rotation, reverse rotation, ESD, thermal protection, phase failure, and over-torque status, respectively.

Both the display and the control cover can be rotated in 90° increments to meet various valve installation directions and positions.

Setting

Setting, adjustment, and viewing can be done using the intrinsically safe IZQ dedicated remote control included with the device, allowing users to easily access the actuator configuration through the LCD display.

Help Screen

Multiple help screens can be called up using the IZQ dedicated remote control tool, allowing for real-time, grouped analysis of control signal status, valve and actuator status, and indication status.

Valve Torque Indication

The output torque limit value of the actuator can be set via the dedicated remote control buttons. The stroke level of the torque switch can be checked and adjusted according to the actual valve operating torque requirements, making the setting more precise and more in line with actual requirements, thereby reducing the possibility of future failures. Problems such as valve pinch points, bottom plates, and lifting forces can be immediately detected and checked and evaluated on site.

In remote control mode, the operation depends on two independent signals. Taking the valve closing command as an example, a remote valve closing input signal and a valve closing interlock input signal are provided simultaneously. The actuator will operate and close the valve. If only one signal is provided or one signal is lost, the actuator will hold its position or stop to prevent failure. For applications requiring ESD, a dedicated ESD input can be used. This input has higher priority than local or remote control signals, so when this signal is applied, any current or applied control signals will be ignored.

Asset Management -- Data Recording

The dedicated remote control can be used to query the actuator configuration and construction information. This product also includes a data recorder that can be used to capture valve, actuator, and control system status information and store this information in memory. This information includes:

Valve Torque Distribution Diagram

Instantaneous and average torque at the corresponding valve opening/closing positions. The reference distribution diagram saved during the debugging phase can be compared with the torque distribution diagram during operation for valve performance analysis.

Startup Log

Startup position diagram at the corresponding valve opening/closing positions. Allows process control valve operation.

Statistics

Number of operations, number of power failures, operating time, maximum torque, last limit switch operation, battery operating time, battery voltage.

Detection Log

Control system, actuator, and indication event logs. Users can replay and filter events of interest, such as "torque stroke." The last 1024 activities will be saved, noting the date and time the event occurred.

Manual Operation

A directly driven handwheel (or a gear-driven handwheel used on larger models and under IZQ) provides reliable emergency manual operation in the event of a power failure. The manual/automatic isolator ensures safe operation even when the motor is running.

Note: Unless the manual/automatic handle is intentionally locked in the "manual" position, motor operation always takes precedence. Both directly driven and independently gear-driven handwheels have a free stroke "hammering" effect.

Non-invasive Setting

All actuator settings and diagnostics are performed using IrDA™ communication through a sealed indicator window without the need to remove the cover on site and expose the internal control mechanism.

Local Control

On-site control switches and local/stop/remote selectors operate internal magnetic reed switches, eliminating the need for a sealed, moisture-proof through-shaft.

Position Control

Hall effect magnetic pulse system, accurately measures and controls the actuator stroke without using any gears or switches.

Wiring Terminal Box

Even when the terminal box cover is opened for on-site wiring, the individually sealed terminal box can effectively ensure the sealing and integrity of the electric device inside.

IZQ Motor and Actuator

The motor shaft and worm gear are independent, allowing for quick replacement of the actuator motor. The low-inertia, high-torque motor allows the motor to quickly reach peak torque after startup, and there is almost no over-limit movement when not energized. A precise temperature sensor inside the temperature coil is unaffected by ambient temperature, keeping the motor at optimal thermal capacity. The motor actuator includes a free-stroke "hammering" device to help open and close tightly closed valves. The worm wheel and worm gear are individually immersed in lubricating oil for operation, suitable for the largest environmental temperature differences.

Thrust Pressure

Cast iron, water-sealed bearing housing, simple, detachable drive shaft sleeve can be machined according to the valve stem for connection with the valve.

Design Features - Reliability:

The synchronizer prevents damage to the valve due to incorrect wiring.

The IZQ electric actuator's unique "synchronizer" automatic rotation adjustment device prevents incorrect motor running direction due to incorrect three-phase power wiring, thus preventing valve damage, ensuring that the IZQ's three-phase motor always has the correct power phase sequence. The synchronizer detects the impending phase rotation and then energizes the appropriate contact points, ensuring that the motor runs in the correct direction and the actuator moves in the correct direction.

Phase Loss Protection

The IZQ controller monitors all three phases of the power supply. If one or more phases are lost, the controller will prevent the device from operating, avoiding "single-phase operation" or even burning out the motor. The actuator will also display power phase loss information and can provide remote alarm status indication from configurable indicator nodes.

IZQ Overheat Protection

If the coil overheats, the temperature regulator in the motor coil directly detects the coil temperature and disconnects the actuator's control circuit.

Instantaneous Reversal Protection

When the actuator receives an instantaneous reversal command, an automatic time-delay circuit prevents unnecessary wear and tear on the valve stem and gearbox from impact loads. This circuit can also limit surge current through the contactor.

Motor Protection When the Valve is Stuck

When the valve is loose, the operating force reaches the maximum value, or the valve is occasionally stuck during operation, the actuator faces the most severe test. IZQ's intelligent functions can systematically handle these problems, ensuring reliable valve operation while providing necessary protection for the valve and actuator.

If the valve may be "stuck," a torque switch bypass can be set at 5% of the valve's correct position for wedge gate valves. This applies "extra" torque to the incorrectly positioned valve, with an average torque of 1.4 to 2 times the rated torque. In most cases, applying extra force will cause the stuck valve to start moving, allowing the equipment to continue operating. After reaching the 5% position, the torque switch returns to the correct setting until the remaining stroke is completed. If this extra torque is still insufficient to move the valve, IZQ will consider the valve to be stuck and stop operating within a few seconds to avoid further damage to the valve or motor burnout.

Automatic Self-Test and Diagnostic Function (ASTD)

At any time, once the actuator is powered on, it will automatically check the operating circuit to ensure correct operation. For infrequent equipment malfunctions, they can be diagnosed and automatically displayed on the screen as icons, while the actuator's electric operation will be prohibited for on-site maintenance.

Design Features - Protection:

Protection is Key

Extensive experience in using electric actuators has enabled the product to achieve a world-leading position in actuator protection. The actuators operate reliably in environments ranging from deserts to tundra, from sea level to underground, in humid, extremely hot or cold, UV-exposed, and highly corrosive air environments. We know that the most important factor in actuator reliability is its resistance to environmental influences—in short, the protective housing.

Double Sealing, Double Protection

IZQ has an IP68 protection rating—submersible to 2 meters for 48 hours, NEMA4/4X16. Completely waterproof and dustproof, and does not "breathe." The "double seal" system ensures that internal components are protected because they are isolated from the terminal box by a waterproof wiring terminal module. Even during on-site wiring, with the terminal cover removed, protection is maintained, and the terminal module cover is sealed.

Non-Invasive - Lifetime Seal

The IZQ does not require removal of the electrical box cover during on-site commissioning. All settings and adjustments, including setting the IZQ speed, are done using the provided infrared setting tool. After assembly in our controlled factory environment, air convection is eliminated, and all internal components are protected for life. Non-invasive control means that no through shafts are used through the control box.

Simple, Reliable

IZQ integrates a simplified design style while expanding specifications and performance.

Valve Position Measurement

Reliable process control depends on accurate positioning at the end of the valve stroke. Hydraulic control depends on accurate positioning in the middle of the valve stroke. The IZQ non-contact valve position measurement system is the simplest design in actuator control. A single moving part resolver converts the rotation of the output center sleeve into an electrical signal, which is then compared to the limit stored in secure, non-volatile memory.

Torque Measurement

The actuator's ability to reliably and accurately determine the force required to operate a valve is fundamental to protecting both the valve and the actuator. The IZQ series uses proven and industry-tested technology to obtain accurate and repeatable torque measurements regardless of frequency, voltage, and temperature variations.

In recent years, the integration of industrial control systems using network connections has become a major feature of the IZQ series of actuators. Actuators using fieldbus control systems simplify, make reliable, and convenient the control and monitoring tasks of modern factories.

All IZQ actuator products have a range of compatible components available, allowing for integration with various communication and process control bus systems. Actuators report status feedback to the overall plant control system (DCS or PLC) and receive valve control commands via various fieldbuses.

The IZQ series actuators can be configured with Foundation Fieldbus, Profibus, Modbus, and DeviceNet buses. Combined with our company's extensive expertise in bus systems, this ensures that the IZQ series actuators consistently provide the most ideal and effective solutions for diverse user control systems. Inserting the appropriate circuit board module into the actuator's electrical socket—typically done during manufacturing—simplifies operation and effectively reduces costs. Use the IZQ Setup Tool Professional and a network testing tool for the selected protocol to test and configure the module.
