Program Controller SE-402

Program Controller SE-402 for small to medium-sized automation solutions

The SE-402 program controller is a universal compact automation device for periodic processes. The controller has been established and proven for small to medium-sized automation tasks for many years. A user friendly operating concept was developed for the SE-402 controller, regardless of its compact design and wide functionality.
In a consistently uniform and easy-to-use mode of operation, the user can optimally configure the instrument for the required automation task by using the integrated software function modules and additional hardware plug-in modules.

Functions are set-up by simple configuration options so that no knowledge of programming is necessary.

Access to the menu functions can be disabled in five levels and enabled by code entries. Digital and analogue inputs and outputs can be assigned without restricting the individual function.
For optimum adaptation to the respective commitment task, the device contains an internal PLC. This function has access to all digital data without the need for external wiring. External plant control tasks can be taken over.

Application fields:
• Dryer
• Tempering furnaces
• Climate-/ cooling simulation chambers
• Laboratory furnaces
• Autoclaves
   ... and much more


Functions:
• Easy menu guided configuration without programming knowledge
• Programmer with 4 set values, 12 digital tracks, 25 programs
• 2 (optional 4) control zones with 8 PID sets of parameters, 1 tolerance band
    and 2 limit values for each zone
• 16 alarms
• 4 formulas
• 8 tolerance bands, 8 limit values
• PLC with 1600 statements, 64 timers and 512 flags, programmable in STL
• Self-optimization function for determination of optimal PID control parameter (Xp, Tn, Tv)
• 5 login levels
• 2 analogue value multiplexer
• Configuration interface RS232
• BCD/binary decoder
    Using the internal PLC function as BCD-, binary or “1 from n”- decoder, analogue values (set
    values, actual values, etc.) can be put out as function outputs. Two decoders can be configured;
    they are operated once per second.
• Humidity calculation
• Free linearization curves
    With the actual value processing can be performed linearizations for all conventional
    thermocouples and Pt100. For other types of actual value sensors two linerization curves
    can be freely defined.
• Actual value correction: For each actual value, up to three correction points can be freely defined.
• Actual value filtering: False measured values can be filtered off with this function.
• Operator panels: Four universally configurable display pages with 10 data lines are available.
• Configuration software ECS View
    Operation of programmer from PC, backup of configurations and programs.
    Remote control via PC per modem.


Operation

Configuration
• Menu-assisted configuration in tables
   (no programming knowledge necessary)
• Easy language switching by menu
• 5 operating levels
• Configurable texts and dimensions
• Configuration backup on PC
• Direct modem connection possible
• Hardware configuration (plug-in card)
• Configuration of all software function modules available in the device
    (actual-, set value, control zone, tolerances, limit values etc.)
• Configuration changes on the device during operation

Programs (Recipes)
• 25 programs with up to 50 segments
• Configurable process steps
• Plain text descriptions for programs (up to 16 characters)
• Graphic representation of set value curves and control tracks
• Configurable program loops (8 loops per program)
• Test, modify, copy, delete programs

Operation
• Control zone overall display
• Graphic set/actual value comparison
• Numerical and graphic data display of set values and tracks
• Representation of actual values, limit values, tolerance values and
    formula values
• Plain text alarm display with history memory
• 4 operator panel display page (freely configurable display pages)
• Jump in the program
• Programming of an automatic program start
• Manual operation for set values and tracks even during program run
• Control parameter auto-optimization (“self-tuning“)
• Manual operation mode for the manipulated variable Y (“Y-Man.“)
