Set of air compressor control, drive and protection circuit at an organic whole, make the installation more simply, quickly, reduce a lot of wiring work and the peripheral equipments purchase, after-sales service more convenient.
★High reliability
High-performance microprocessor makes digital processing on control system, it avoids excessive adjustment on analog lines and achieves excellent accuracy and speed of execution.
★Strong anti-jamming performance
All external control signals use Photoelectric isolation and set a different anti-noise level. It fits for special industrial environment application..
★Easy adjustment method
With wide application range of control system, easy and intuitive adjustment. Through a variety of function options to match different types of control object.
★Optimized structure
Unique compact design of internal structure, particularly user-friendly make it integrated into existing system. It saves costs of current transformer and bypass contactor costs for users.
★Adaptive power frequency
Power frequency 50/60 Hz, adaptive function, user-friendly.
★Improved protection function
A variety of motor protection functions (Such as over-current, input/output phase default, thyristor short circuit, overheat protection, leakage detection, electronic thermal overload, phase current imbalance, etc.) ensures that motor and soft starter will not be damaged in case of failure or malfunction.
★Easy to maintain
Monitoring signal coding system consists of four digital display, which monitors system equipment's working conditions, while providing rapid fault diagnosis.

Control Process
Maintenance
Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
Brush the dust with clean and dry brush.
Remove dust with compressed air machine.
2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
(1) Blow it with a hair dryer or electric stove.
(2) Bring it to power distribution room for dehumidification.
3. Regularly check components' intact. Whether it can work properly.
4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
Before maintenance checking, it has to cut off all power in the line side of soft starter.
