User manual OMRON E5AK

[. . . ] E5AK Digital Controller User's Manual Cat. H083-E1-03 Preface Thank you for your purchase of your E5AK, intelligent digital controller. The E5AK allows the user to carry out the following: · Select from many types of temperature and analog input (multiple input) · Support position-proportional control (position-proportional type controllers only). · Select output functions such as control output or alarm (output assignment) · Use the HBA (heater burnout alarm) function (standard type controllers only). [. . . ] · The "MV at PV error" parameter sets the manipulated variable when an input error occurs. On a position-proportional type controller, this parameter sets the action (close/hold/open) when an input error occurs. · Standard type Control Method Standard Heating and cooling Setting Range -5. 0 to 105. 0 -105. 0 to 105. 0 Unit % % Default 0 0 Comment The manipulated variable at the cooling side during heating and cooling control is expressed as a negative value. · Position-proportional type Setting Range [ ]: Hold/[ ]: Open/[ ]: Close Unit None Default See F Related articles MV at stop MV at PV error : 3. 6 Starting and Stopping Operation (page 3-13) : 8. 2 How to Use the Error Display (page 8-3) 5--21 CHAPTER 5 PARAMETERS Level 2 Mode MV upper limit MV lower limit MV change rate limit Conditions of Use The control must be advanced PID control, and ST must be set to OFF. Function · The "MV upper limit" and "MV lower limit" parameters set the upper and lower limits of the manipulated variable. When the manipulated variable calculated by the E5AK controller is outside of the upper-and lower-limit range, the upper limit or lower limit set to these parameters is output, respectively. However, note that these parameters are disabled during position-proportional control. · The "MV change rate limit" parameter sets the maximum permissible change width per second of the manipulated variable (on the position-proportional control, valve opening). If a change in the manipulated variable (on the position-proportional control, valve opening) causes this parameter setting to be exceeded, the calculated value is reached while changing the value by the per-second value set in this parameter. This function is disabled when the set value is "0. 0". · MV upper limit The setting ranges during standard control and heating and cooling control are different. Also, the manipulated variable at the cooling side during heating and cooling control is expressed as a negative value. Control Method Standard Heating and cooling Setting Range MV lower limit +0. 1 to 105. 0 0. 0 to 105. 0 Unit % % Default 105. 0 105. 0 Comment · MV lower limit The setting ranges during standard control and heating and cooling control are different. Also, the manipulated variable at the cooling side during heating and cooling control is expressed as a negative value. Control Method Standard Heating and cooling Setting Range -5. 0 to MV upper limit -0. 1 -105. 0 to 0. 0 Unit % % Default -5. 0 -105. 0 · MV change rate limit Setting Range 0. 0 to 100. 0 Unit % Default 0. 0 F Related article 4. 2 Operating Condition Restrictions/Manipulated variable restrictions (page 4-5) See 5--22 Level 2 Mode Input digital filter · Sets the time constant of the input digital filter.

Function Setting Range 0. 1 to 20. 0 Comment Unit % Default 0. 8 F Related article 4. 1 Selecting the Control Method/Position-proportional Control (page 4-3) See E5AK-PRR2 AC100-240 E5AK-PRR2 AC/DC24 Model 5--23 CHAPTER 5 PARAMETERS Level 2 Mode Alarm 1 hysteresis Alarm 2 hysteresis Alarm 3 hysteresis Conditions of Use Alarms must be assigned as outputs. For example, if alarm outputs 1 and 2 only are assigned as outputs, the "alarm 3 hysteresis" parameter cannot be used. · This parameter is for checking the hysteresis of alarm outputs 1 to 3.

These parameters include parameters for specifying the input type, scaling, output assignments, and direct/reverse operation. · To select this mode when in the levels 0 to 2, expansion, option and calibration key for 1 second minimum. The display changes to the menu modes, press the ] using the key then press the key for 1 display. If you select [ second minimum, the controller enters the setup mode. · To select parameters in this mode, press the or keys.
