The top of the screen displays valve position and alerts in real-time through a low-power segment code LCD, while the bottom presents operating data and parameter settings via a graphic dot matrix LCD. Available in both Chinese and English, it ensures user-friendliness worldwide. This innovative technology resolves issues of stability and reliability, enhancing the machine's overall dependability.
2.4 Communication Control and Monitoring Technology
The Bluetooth communication remote control mode offers unmatched convenience, allowing remote actuator control via computer or mobile. Equipped with smart remote control software, it facilitates both local and remote analysis.
2.5 Double Seal and Non-intrusive Technology
With an IP68 protection standard, these actuators are completely waterproof and dustproof. The 'Double Seal' feature ensures that internal components remain safeguarded. The operation knob receives double protection, with an optional protective cover for outdoor applications, safeguarding it comprehensively.
All calibration and parameter adjustments happen without needing to open the box cover. Using a magnetic control knob, infrared remote, or handheld PDA, settings and debugging are seamlessly executed.
2.6 Comprehensive Protection and Self-diagnosis Function
a. Automatic Phase Sequence Correction: This feature automatically aligns the phase sequence, ensuring the three-phase motor always operates with the correct power sequence, thus preventing valve damage from incorrect wiring.
b. Phase Loss Protection: Safeguarding the motor from potentially catastrophic damage, our controller vigilantly monitors the three-phase power supply. If a phase loss is detected during motor operation, it halts immediately, and if at rest, movement is prohibited. An alert is visibly displayed on the on-site LCD, while remote indication contacts provide instant updates.
c. Torque Protection: Tailor your actuator's safety with user-defined protection values for torque overload-adjustable between 40-100% of rated torque. Upon reaching or exceeding these limits, the motor ceases operation and triggers an alarm, ensuring peace of mind and operational security.
d. Motor Stall Protection: With real-time current monitoring, our system ensures immediate cessation of motor function if stalling occurs, effectively safeguarding both motor and actuator from potential harm.
e. Valve Stuck Protection: When faced with challenging conditions, our actuator provides maximal torque for a designated period to dislodge stuck valves. If unsuccessful, power to the motor is cut, preventing further strain or damage.
f. Motor Overheat Protection: Integrated temperature regulators detect excess heat within the motor coil, promptly disconnecting the actuator's control circuit to avert overheating and potential damage.
g. Instantaneous Reversal Protection: Combatting impact load-induced wear, an automatic delay circuit is employed during rapid command reversals. This feature also mitigates surge currents, preserving the integrity of valve stems and gearboxes.
h. Automatic Self-Detection and Diagnosis (ASTD): Upon power-on, the actuator conducts a self-assessment to ensure flawless operation. Any rare faults are iconically displayed on-screen, with valve operation disabled to aid efficient on-site troubleshooting.
i. Data Record Protection: Even during power outages, vital parameters are securely stored in EEPROM, retaining information for up to 20 years without risk of data loss.
j. Surge Protection (Lightning Arrester): Customize your actuator's defense with AC and signal surge protectors, fortifying it against lightning strikes and ensuring uninterrupted performance.
k. Anti-Condensation Heating Protection: Maintain optimal conditions within the electrical cavity by adjusting the heating resistor, effectively preventing condensation and safeguarding the actuator's functionality.
2.7 Local Control
AUKEMA actuators boast dual non-intrusive magnetic control knobs: a mode knob with 'local', 'remote', and 'stop' positions, and an operation knob with 'open' and 'close' positions. In 'local' mode, simply turn the operation knob to direct actuator movement. Choose between 'jog' and 'hold' for tailored control.
2.8 Remote Control
With seamless integration to DCS or PLC systems via hard-wired connections, experience effortless actuator control through manual switch or automatic current commands.

2.9 ESD Control - Unparalleled Safety and Security
In critical situations, our advanced ESD signal system triumphs over any local or remote commands (as per parameter settings), enabling you to decisively close or open the valve. Customize your ESD action with options like 'close the valve', 'open the valve', or 'hold position' for enhanced operational control.
2.10 Interlock Control - Precision at Your Command
For intricate applications, configure the actuator for conditional control, meeting even the most demanding requirements with ease and precision.
In conditional mode, the actuator operates based on two independent signals. For instance, simultaneous remote close and close interlock input signals trigger the actuator to close the valve. In scenarios where only one signal is provided or lost, the actuator will hold or stop, averting potential failure. For ESD applications, a dedicated ESD input takes precedence, overriding any local or remote control signals when engaged.
