The 'Double seal' mechanism safeguards internal components, while an optional protective cover for outdoor applications adds a layer of defense to the operating knob. This innovative design ensures complete convenience in safeguarding equipment in various environments.
All calibration and parameter configurations can be achieved without unsealing the box. The magnetic control knob, infrared remote, or handheld PDA provides convenient options for parameter setting and debugging.
2.6 Comprehensive protection and self-diagnosis function
a. Automatic phase sequence correction: This sophisticated function automatically adjusts the phase sequence, guaranteeing that the three-phase motor maintains the correct power phase sequence. It effectively prevents valve damage stemming from incorrect electrical connections.
b. Phase Loss Protection: Safeguard your motor from potential damage! When a three-phase motor experiences a phase loss, it risks overheating and burning out. Our intelligent controller diligently monitors the power supply's three phases. If any phases are lost, the motor halts immediately if in motion, or remains immobile if static. An on-site LCD screen displays a power phase loss alarm, while configured indication contacts provide remote indication information.
c. Torque Protection: Tailor torque safety to your needs! Users can set specific protection values for excess torque, ranging between 40-100% of the rated torque, for both opening and closing actions based on site conditions. If the electric actuator's actual torque meets or exceeds the set value, the motor ceases rotation instantly, accompanied by an alert.
d. Motor Stall Protection: Real-time motor current monitoring ensures immediate cessation of motor activity upon stalling, safeguarding both the motor and actuator from potential harm.
e. Valve Stuck Protection: When actuators perform valve opening at closed limits, the torque protection function temporarily pauses. Valves in a stuck position are opened with maximum motor torque. If unsuccessful within the set time, power to the motor is disengaged.
f. Motor Overheat Protection: Dual temperature regulators within the motor coil detect coil temperature directly. If overheating occurs, they disengage the actuator's control circuit, ensuring motor safety.
g. Instantaneous Reversal Protection: An automatic delay circuit activates upon receiving an instantaneous reversal command, guarding against impact loads that could cause undue wear on the valve stem and gearbox. Furthermore, it limits surge current through the contactor.
h. Automatic Self-detection and Diagnosis (ASTD): Upon power-up, the actuator conducts an automatic operational circuit check to verify correct functioning. Should rare equipment failures arise, diagnostics are displayed iconically on-screen, and electric valve operation is inhibited for easier on-site maintenance.
i. Data Record Protection: Paramount data security! Even during main power outages, various parameters are securely stored in EEPROM, ensuring they remain intact for up to 20 years.
j. Surge Protection (Lightning Arrester): Opt for an AC power surge protector and/or a signal surge protector to offer lightning protection tailored to your actuator's needs.
k. Anti-condensation Heating Protection: Adjust the heating resistor settings based on the electrical cavity's temperature, providing anti-condensation heating protection perfectly suited for the valve actuator.
2.7 Local Control
AUKEMA actuators feature two intuitive magnetic control knobs, ensuring seamless operation. The mode knob offers three positions: 'local', 'remote', and 'stop'. The operation knob provides 'open' and 'close' settings. With the mode knob set to 'local', toggling the operation knob determines the actuator's movement. Choose between 'jog' and 'hold' for precise local control.
2.8 Remote Control
Seamlessly integrate with DCS or PLC using a hard-wired cable to control the actuator through switch quantity (manual) or current quantity (automatic) settings.
Switch quantity control includes three input terminals: valve opening, valve closing, stop/hold. Choose between inching and holding modes. Auxiliary control features emergency protection (ESD), valve opening interlock, and valve closing interlock. Remote input undergoes photoelectric isolation, withstanding surges up to 2.5KV.
Our state-of-the-art remote analog quantity control utilizes sophisticated linear optocoupler isolation, allowing precise valve positioning based on the input signal ratio. This ensures exceptional accuracy and control.
Our advanced remote analog quantity valve position feedback seamlessly transmits valve position data to DCS or PLC systems via a reliable 4-20mA signal. Additionally, you have the option to select remote analog feedback of torque, offering comprehensive monitoring.
2.9 ESD Control
In urgent scenarios, the ESD signal can take precedence over any local or remote inputs (configured as per parameter settings), enabling the actuator to decisively open or close the valve. You can choose the ESD action to be 'close the valve,' 'open the valve,' or 'hold position,' providing flexibility and safety.
2.10 Interlock Control
For high-demand tasks, the actuator is configurable for conditional control, offering robustness and reliability.
In this strategic mode, operation relies on two independent signals. For instance, if both a remote close input and a close interlock input signal are active, the actuator will assuredly close the valve. If only one signal is active or in case of a signal loss, the actuator will hold or cease operations to prevent system failure. For ESD applications, a dedicated ESD input is available, which supersedes local or remote control signals. Thus, when engaged, all other control signals are disregarded.

FAQ
Q1: Do you have any standard international certificates?
*We have ISO9001, ISO14000, CE, UL and other certifications. Our products also have sepcial deisgn patents.
Q2: Are there any special certification requirements for this product?
*There are certification requirements for explosion-proof actuators in China. They must have explosion-proof certificates and production licenses issued by the National Explosion-proof Electrical Inspection Center. By 2020, the production license will be cancelled and converted to 3C certification. Coal mine products have mining product safety mark certificates (referred to as coal safety certification) and mining product explosion-proof certificates. This coal mine certification product is our company's advantage product. At present, in the electric actuator industry, only 6 actuator manufacturers in China have such mining valve actuator certificates. Domestic coal mines must have products with this mining safety certificate to be used on pipelines underground in coal mines. Therefore, compared with other ground products, there will be less competition in the coal mine sector. Now the company's export of coal mine products is also rising year by year.

Q13: Does this product have a service life?
*Yes, the service life is related to the switching frequency of the valve. The valve is installed on the pipeline, and the electric actuator is a device that controls the valve switch. If the valve switching frequency is very high, the actuator will be used more frequently, and the internal gears and turbines, worms, nuts, etc. will have certain wear, but it is much longer than the service life of the valve. Some valves on pipelines need to be replaced after a few years. Generally, the actuator will be replaced at the same time as the valve. At present, our products are used on pipelines, and many actuators from more than 10 years ago are also in normal use.
