Page 1: Wiring Diagram for CX9330A-M Wiring Diagram for CX9330A-V

CX9330A efficiently controls screw type air compressor based on microprocessor, gives users an

alarm against trip by checking the status of the machine in advance and offers users information for

maintenance and let them treat it quickly and easily.

Also, it is the cutting-edge electronic controller mounted with VSD (Variable Speed Drive) based on

PID control system, which can help users to save more than maximum 30% of the energy costs.

- Reducing the energy costs using VSD (Variable Speed Drive)

- Applying for the 128×64 size graphic LCD displayed by multi-language

(Korean, English, Chinese and Japanese, etc.)

- Easy analyzing for the trouble by storing up to maximum 50 numbers of trip alarm history

(Black box function)

- Notifying the information and expected time for PM(preventative & maintenance) and exchanging

RSP (recommended spare parts) schedule

- Devide access code by user to prevent mishandle.(changeable)

- Automatic recovering from CPU down caused by noise

- Various analogue output function (Inverter speed control, delivery press. Retrans.)

- Establishing the most optimized system embedding high-function and high-efficiency in spite of

monolithic small size

- Providing perfect interface with upper systems by mounting RS485 communication,

MODBUS RTU international standard protocol

Fast and easy control - The most advanced screw air controller

Using inverter, the revolution of motor can be freely set up by either a microprocessor or users,

so it is possible to start and stop flexibly. Also, it has users reduce energy cost by getting efficient

and economic operation cost comparing with existing air compressor with other controllers.

CX9330A efficiently controls screw type air compressor based on microprocessor, gives users an

alarm against trip by checking the status of the machine in advance and offers users information for

maintenance and let them treat it quickly and easily.

Also, it is the cutting-edge electronic controller mounted with VSD (Variable Speed Drive) based on

PID control system, which can help users to save more than maximum 30% of the energy costs.

- Reducing the energy costs using VSD (Variable Speed Drive)

- Applying for the 128×64 size graphic LCD displayed by multi-language

(Korean, English, Chinese and Japanese, etc.)

- Easy analyzing for the trouble by storing up to maximum 50 numbers of trip alarm history

(Black box function)

- Notifying the information and expected time for PM(preventative & maintenance) and exchanging

RSP (recommended spare parts) schedule

- Devide access code by user to prevent mishandle.(changeable)

- Automatic recovering from CPU down caused by noise

- Various analogue output function (Inverter speed control, delivery press. Retrans.)

- Establishing the most optimized system embedding high-function and high-efficiency in spite of

monolithic small size

- Providing perfect interface with upper systems by mounting RS485 communication,

MODBUS RTU international standard protocol

Fast and easy control - The most advanced screw air controller

Using inverter, the revolution of motor can be freely set up by either a microprocessor or users,

so it is possible to start and stop flexibly. Also, it has users reduce energy cost by getting efficient

and economic operation cost comparing with existing air compressor with other controllers.
