User manual OMRON E5EK PROGRAMMABLE TYPE

[. . . ] 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). Before using your E5EK-T thoroughly read and understand this manual in order to ensure correct use. [. . . ] Changes smaller than the detection width due to LBA detection timing are not regarded as changes. · The following example describes what happens when a heater burnout occurs at maximum output. LBA detection time LBA detection time F LBA detection width F LBA detection example PV LBA detection width Output Time Heater burnout LBA=ON · LBA judgment is carried out at each LBA detection time from the point of maximum output. In the above figure, the process value (PV) is changing greatly at the 1st judgment time band, so LBA remains OFF. · At the 2nd judgment time band, the process value increases as indicated by the broken line if the process value is normal. This means that the change width exceeds the LBA detection width, and LBA output remains OFF. · If the heater burns out at the point shown in the above figure, the process value "decreases. " Accordingly, it is judged that "the process value is not changing in the increasing direction" at the 2nd judgment time band and the LBA output becomes ON. 4--26 4. 10 LBA F Setting the LBA detection time · The LBA detection time is automatically set by auto-tuning (except in heating and cooling control). · If the optimum LBA detection time cannot be obtained by auto-tuning, set the time in the "LBA detection time" parameter (level 2 mode). F Determining the LBA detection time · Calculate the LBA detection time as follows: (1) Set output to maximum. (2) Measure the time it takes for the input change width to reach the LBA detection width (factory setting: 0. 2% FS). Measurement time Tm PV 0. 2%FS Output Time LBA detection time = Tm x 2 (3) Take a value twice that of the measurement time as the LBA detection time.

F Transfer output type · You can select the following five data items in the "transfer output type" parameter (option mode) as the transfer outputs: Present SP (default), Process value, Manipulated variable (heat), Manipulated variable (cool), Valve opening However, note that heating/cooling side manipulated variables can be output only on standard type controllers, and valve opening can be output on position-proportional type controllers. · If the output assignment is changed when either the "manipulated variable (heat)" or "manipulated variable (cool)" parameter is selected, the factory setting "set point" is returned to. F Transfer output scaling · These transfer outputs can be scaled according to the settings of the "transfer output upper limit" and "transfer output lower limit" parameters before output. Setting of an upper limit value smaller than the lower limit value is allowed, so reverse scaling can also be carried out. Also, the scale can be enlarged by the upper- and lower-limit width specified for each data item. The following example shows scaling of the heating side manipulated variable.

Monitor Describes a procedure using parameters in operating instructions. Example of use Describes related parameters and items. See Describes models of the E5EK-T or optional units that support the parameter being described. Model J About parameter display On the E5EK-T controller, only parameters that can be used are displayed. These parameters are displayed only when the "Conditions of Use" on the right of the parameter heading are satisfied. However, note that the settings of protected parameters are still valid, and are not displayed regardless of the conditions of use. AT Execute/cancel Conditions of Use The controller must be in operation. J About the Order in Which Parameters Described in This Chapter Parameters are described mode by mode The first page of each mode lists the parameters available in that mode. The parameter names in these contents are listed in the order that they are displayed on the controller. 5--2 Protect Mode · The protect function restricts key use to prevent unwanted key operation. Before changing parameters in this mode, first make sure that protecting the keys will not cause any problems in operation. keys simultaneously for 1 second · To select this mode, press the RUN/RST and minimum.
