Parameter adjustments and system debugging are effortlessly managed without box cover removal, thanks to options like the magnetic control knob, infrared remote control, or handheld PDA.
2.6 Comprehensive Protection & Self-Diagnosis Functionality
a. Revolutionary Automatic Phase Sequence Correction: This automatic feature aligns the phase sequence, ensuring the three-phase motor maintains the correct power phase sequence, thereby preventing potential valve damage from incorrect wiring.
b. Phase loss protection: Safeguard your operations with our advanced phase loss protection. If any phase is lost, whether the motor is in motion or static, our controller intervenes immediately. It stops the motor to prevent overheating and potential burnouts. A power phase loss alarm will alert you on the on-site LCD screen, while remote indication information can seamlessly be accessed from the configured indication contacts.
c. Torque protection: Customize protection values for both opening and closing actions, tailored to your on-site conditions (ranging from 40-100% of the rated torque). Should the electric actuator's actual torque hit or surpass these values, the motor halts immediately, accompanied by an audible alarm, ensuring your equipment stays within safe operational limits.
d. Motor stall protection: With real-time current monitoring, our system provides immediate motor stall protection. It halts the motor instantly to shield both motor and actuator from potential harm, optimizing reliability and longevity.
e. Valve stuck protection: In closed limit scenarios, if the actuator attempts to open the valve and detects a stuck position, it bypasses torque protection temporarily. The valve will be opened with maximum torque permissible by the motor. If unsuccessful, the power supply is cut off, ensuring motor protection.
f. Motor overheat protection: Dual temperature regulators in the motor coil detect overheating promptly, disconnecting the actuator's control circuit to prevent damage, sustaining operational integrity.
g. Instantaneous reversal protection: Our automatic delay circuit safeguards against impact loads from instantaneous reversal commands, minimizing unnecessary wear on the valve stem and gearbox, while controlling surge currents through the contactor.
h. Automatic self-detection and diagnosis function (ASTD): Upon powering, the actuator self-assesses its operating circuit, ensuring reliable operation. Rare failures are diagnosed promptly, with issues displayed iconically on-screen, while automatically prohibiting faulty electric operation, streamlining maintenance.
i. Data record protection: Preserve your critical actuator parameters securely in the EEPROM, with a reliable 20-year retention, safeguarding against power outages.
j. Surge protection (lightning arrester): Opt for either AC or signal surge protectors to fortify your valve actuator against lightning strikes, ensuring uninterrupted protection and performance.
k. Anti-condensation heating protection: Adapt the activation of the heating resistor based on cavity temperature to combat condensation, bolstering the valve actuator's resilience in varied environments.
2.7 Local control
AUKEMA actuators offer intuitive local control with two magnetic knobs. The mode knob toggles between 'local', 'remote', and 'stop', while the operation knob selects 'open' or 'close'. In 'local', you control actuator movement precisely. Choose between 'jog' and 'hold' for tailored operation.
2.8 Remote control
Integrate seamlessly with DCS or PLC systems via hard-wired cables. Enable precise control of the actuator through switch quantity (manual) or current quantity (automatic) settings for diverse applications.
The switch quantity control features three input terminals: valve opening, valve closing, and stop/hold, with modes for inching and holding. Auxiliary controls provide emergency (ESD), valve opening, and closing interlocks. Photoelectric isolation offers robust 2.5KV surge protection for remote inputs.
Remote analog quantity control uses linear optocoupler isolation, allowing precise valve positioning based on analog signal input ratios, enhancing responsiveness and accuracy.
Experience seamless integration with remote analog valve position feedback, effortlessly relaying precise valve positions to your DCS or PLC systems via a 4-20mA signal. Additionally, enhance your control capabilities with optional torque feedback for optimal system management.
2.9 ESD Control
In critical situations, the ESD signal can assert full control, prioritizing safety by overriding all local and remote inputs based on configured parameters. Choose from flexible ESD actions - 'close the valve', 'open the valve', or 'hold position' - ensuring complete operational security.
2.10 Interlock Control
For complex and demanding operational requirements, configure the actuator for conditional control, providing tailored responses based on specific conditions.
In conditional control mode, the operation hinges on the presence of two distinct signals. For instance, when a remote close input and a close interlock signal co-occur, the actuator will close the valve. Absence or failure of one signal results in a hold or stop, averting operational risks. For ESD-critical scenarios, a specialized ESD input supersedes all other control signals, ensuring paramount safety and reliability.
2.11 Diverse Fieldbus Connections
