INTRODUCTION

CN9400

The CN9400 is a 1/16 DIN dual display, dual output miniature controller with PID control strategy.

Control can be optimised with a single shot autotune either on initial warm-up or at setpoint. The second setpoint can be configured in a variety of alarm modes or PID Heat-Cool strategy. A programmer offers a single ramp to setpoint with a choice of timed soak period before switching off the output.

Control of non temperature processes is achieved by the provision of linear input ranges and scaling in commonly used engineering units.

Serial communication is available as an option, and the easy to use CN9-SWis a graphic WINDOWSTM based software package designed for PC supervision of up to 32 instruments, for remote adjustment, configuration, cloning, saving and retrieving settings to files and logging and charting in real time.

CN9-SWuses the MODBUS® protocol via either a fully isolated RS232 or RS485 link depending on the number of instruments and the transmission distances involved in the application.

A users manual is supplied with the comms option. For more information contact OMEGA. For details, see rear cover.

It is suggested that users read the OVERVIEW section of this manual before any installation or setting-up procedures are undertaken.

Note: The controller will not be operational until either the QUICK-STARTor SET-UPprocedure has been completed.
