Functional features
Absolute magnetic encoder technology and power - off valve position display technology
AUKEMA series adopts the absolute value encoder with independent intellectual property rights, which can detect the number of turns up to 4000, the resolution of single turn is 4096 positions, and the absolute position travel detection with the total number of 24 bits. The unique design of low power battery power supply circuit, after the main power supply power, use battery power supply, continue to show the change of valve position. Absolute value encoder adopts magneto-electric technology, which has the characteristics of simple structure, stable performance, long service life, high precision and high resolution. The battery is only used to display the valve position after thousands of power consumption. Even if the battery is dead, absolute coding technology is adopted by thousands to continuously track the valve position change operated by hand wheel, which greatly improves the stability of the system.
Torque and force sensing technology
By adopting the advanced torque pressure sensing technology which is widely used in the world, AUKEMA electric actuator torque dynamic real-time high-precision detection is realized.Torque pressure sensing technology is tested and verified by industry practice.Precise, repeatable torque measurements can be obtained regardless of any change in frequency, voltage, and temperature.

The upper half of the screen adopts low-power segment type LCD display, which can display the valve position and alarm symbol in real time with thousands.The second half of the screen adopts graphics dot matrix liquid crystal display, which is used to display operation information and parameter setting.One-screen dual-display technology solves the problem of stability and reliability of two screens and improves the reliability and availability of the whole machine.
Bluetooth communication control and monitoring technology
Bluetooth communication remote control mode, to provide you with the convenience of computer and mobile phone remote control actuator, you can provide intelligent remote control software for local and remote analysis.
Double seal and non - invasive technology
IP68 protection grade, completely waterproof and dustproof."Double seal" ensures internal components are protected.Double protection of the knob is operated. Optional protective cover is added on the side of the knob panel, providing convenience for outdoor application of the protective knob.
All debugging and parameter setting can be completed without opening the cover of the box. Parameter setting and debugging can be done through magnetic control knob, infrared remote control or hand-held PDA.
Comprehensive protection and self-diagnosis function
A. Automatic phase sequence correction: automatically adjust the phase sequence to ensure that the three-phase motor always has the correct power phase sequence.To prevent valve damage caused by incorrect power connection.
B. Lack of phase protection: three-phase motor will overheat and burn out when running without phase.The controller monitors the three phases of the power supply.When - or multi-phase power supply is lost, if the motor is in motion, stop immediately;If the motor is static, it will be prevented from acting.At the same time, the power failure alarm will be displayed on the field LCD, and the remote indication information can be obtained from the configuration indicator contact.
C. Torque protection: the user can set different protection values of over-torque in on and off directions according to the field conditions (the range can be set as rated torque
When the actual torque borne by the electric actuator reaches or exceeds the set protection value, immediately stop the motor rotation and alarm.
D. Motor blocking protection: real-time monitoring of motor current can stop motor action in real time when motor blocking occurs.Protect motor and actuator.
E. Dead valve protection: when the actuator closes the limit and performs the valve opening action, it does not perform the torque protection function within a fixed period of time, and opens the valve in the stuck position with the maximum torque provided by the motor. If the valve cannot be opened after this period of time, the power supply to the motor will be cut off.
F. Motor overheating protection: if the coil is overheating, the two temperature regulators in the motor coil can directly detect the temperature of the motor coil.And disconnect the control circuit of the actuator.
G. Instantaneous reverse protection: when the actuator receives the instantaneous reverse command, the automatic delay circuit is used to prevent unnecessary wear of the valve stem and gear box caused by shock load.The circuit can also limit the surge current through a contactor.
H. automatic self-detection and diagnostic function (ASTD): at any time, once the actuator is connected to the power, it will automatically detect the operating circuit.To ensure correct operation.For thousands of rare device failures, it can be diagnosed and automatically displayed on the screen as an icon.At the same time, the electric operation of the valve actuator will be prohibited for easier field maintenance.
I. Data record protection: when the main power supply is off, the valve actuator stores various parameters in EEPROM, without loss for 20 years:
J. Anti-surge protection (lightning protection) : ac power anti-surge protection and signal anti-surge protection can be selected according to needs to achieve lightning protection of valve actuator.
K. Anti-condensation heating protection: the heating resistance can be opened or closed according to the temperature in the electrical cavity to achieve the anti-condensation heating protection of the valve actuator.
Local control
The AUKEMA actuator provides two non-invasive magnetic control knobs, one for the mode knob, with three positions: "in place", "remote" and "Stop"; The other is the operation button, which has two positions: "on" and "off". When the mode button is in place, turn the operation button to the "on" or "off" position controls the actuator action in the direction of "on" or "off". There are two ways of local control: "inching" and "holding".
The remote control
After the DCS or PLC is connected to the field actuator by hardwired cable, the actuator can be controlled by switch quantity (manual)/current flow (automatic).
Switch quantity control has three input terminals, namely valve opening, valve closing, stop/hold, optional inching and holding mode;In addition, the auxiliary switch quantity control is emergency protection (ESD), valve opening interlock and valve closing interlock.Remote input adopts photoelectric isolation and can resist 2.5kv surge.
Remote analog control adopts linear optocoupler isolation, and the valve can be positioned proportionally according to the input analog signal.
Remote analog valve position feedback, valve position can be fed back to DCS or PLC through 4-20ma signal;At the same time, remote analog torque feedback can be optionally provided.
ESD control
In an emergency, the ESD signal can override any field or remote signal (depending on parameter setting), enabling the actuator to enforce valve closing or valve opening. ESD operation can be selected as "valve closing", "valve opening" or "position preserving".
Interlock control
In applications where thousands of high requirements are required, the actuator can be configured to achieve conditional control.
In this mode, the operation depends on two independent signals.In the case of the valve closing command, the actuator closes the valve by providing a remote valve closing input signal and a valve closing interlock input signal.If only one signal is provided or one signal is lost, the actuator will hold or stop to prevent failure.For applications requiring ESD, dedicated ESD input can be used.This input has a high priority of thousands of local or remote control signals.Thus, any current or applied control signals are ignored when such signals are applied.
