User manual OMRON E5EK PROGRAMMABLE TYPE

[. . . ] Digital Controller (Programmable Type) User's Manual Cat. H089-E1-02 Preface The E5EK-T is a high-performance programmable digital controller. The E5EK-T allows the user to carry out the following: · Set program patterns to each step by time or ramp rise rate · Execute advance, hold and reset step operations · Execute continuous operation of all patterns and repeated operation of same patterns · Check the start of each step or program end time by signals. · Count time from the beginning of each step (time signal) · Select from many types of temperature and analog input (multi-input) · Support position-proportional control (position-proportional type controllers only) · Select output functions such as control output or alarm output (output assignment) · Use the HBA (heater burnout alarm) function (standard type controllers only) · Monitor the control loop by LBA (Loop Break Alarm) · Use the communications function · Calibrate input or transfer output · The E5EK-T also features a watertight construction (NEMA4: equivalent to IP66). [. . . ] To change the manipulated variable, or keys. If this mode is switched to during auto-tuning, auto-tunuse the ing is canceled. and keys · To select this mode when in the level 0 to 2 modes, press the simultaneously for 1 second minimum. To exit this mode, press the and keys simultaneously again for 1 second minimum. · "Manual MV" is the only parameter available in this mode. Manual MV Function · Sets the manipulated variable or the valve opening for manual operation. On a standard type controller, when you press the or keys, the manipulated variable key, is changed. On a position-proportional type controller, when you press the key, the close side becomes the open side becomes ON, and when you press the ON. · On standard type controllers, the process value is displayed on the No. 1 display and the manipulated variable is displayed on the No. 2 display. · On position-proportional controllers, the process value is displayed on the No. 1 display, and the valve opening is displayed on the No. 2 display when the potentiometer is connected. · On standard type controllers, the manual MV is held when the power is interrupted. · Standard type Setting Control Method Standard Heating and cooling Setting Range -5. 0 to 105. 0 -105. 0 to 105. 0 Unit % % Default 0. 0 0. 0 · Position-proportional type Control Method Position-proportional Monitor Range -10. 0 to 110. 0 Unit % F Related description 3. 8 Adjusting Control Operation/Manual operation (page 3-22) See 5--5 CHAPTER 5 PARAMETERS Level 0 Mode · The parameters in this mode can be used only when the "security" parameter (protect mode) is set to "0" to "5". Only the "PV/Present SP" parameter can be used when the "security" parameter is set to "6". · The parameters in this mode comprise step operation parameters and parameters required for monitoring program operating states. The display changes · To select this mode, press the ] then press the key for 1 second to the menu display. If you select [ minimum, the controller enters the level 0 mode. · To select parameters in this mode, press the or keys. To change parameter set- · The following table shows the parameters supported in the level 0 mode and the page where the parameter is described.

Function · The decimal point position is dependent on the selected sensor during temperatures input and on the results of scaling during analog input. Monitor Range Process Value Present SP Scaling lower limit -10%FS to scaling upper limit +10%FS Set point lower limit to set point upper limit Unit EU EU Monitor · During temperature input, the range of the currently selected sensor is taken as the PV monitor range. F Related parameters "Input type" "Scaling upper limit" "Scaling lower limit" "Decimal point" (setup mode) "Set point upper limit" "Set point lower limit" (expansion mode) See 5--6 Level 0 Mode Pattern No. · This parameter can be set only when the controller is reset. Function · Displays the execution pattern during program operation, and the set pattern after the controller is reset. · This parameter can also be used in the program mode.
