User manual OMRON E5EK

[. . . ] H085-E1-03 Preface Thank you for your purchase of your E5EK, intelligent digital controller. The E5EK 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). · Use four setpoints (multi-SP function) · Use remote SP input. [. . . ] After AT execution, the "PID" and the "LBA detection time" (LBA: Loop Break Alarm) parameters are set automatically. · During heating and cooling control or position-proportional control, only 100%AT can be executed. · When this parameter is selected, the setting becomes [ ], and to execute 100%AT, select [ ]. During · To execute 40%AT, select [ execution of auto-tuning, the AT LED flashes. However, note that during heating and cooling control or position-proportional control, [ ] is not displayed. · When AT execution ends, the parameter setting automatically returns to [ ].

Function · Switches set points 0 to 3 by event input for use as the set point (local SP). · Of set points 0 to 3, the number of valid set points is designated by the "multi-SP function" parameter. · The following table shows the relationship between event input and the selected parameter. Multi-SP Function Event Input Set Point 0 Set Point 1 Set Point 2 Set Point 3 1 1 OFF ON 1 OFF ON OFF ON 2 2 OFF OFF ON ON · When the set point has been changed, the setting of whichever is selected in event input, "set point 0" to "set point 3", is linked and changed. · The decimal point position is dependent on the selected sensor during temperature input and on the results of scaling during analog input. 5--11 CHAPTER 5 PARAMETERS Level 1 Mode Setting Range Set point lower limit to Set point upper limit Comment Unit EU Default 0 See F Related article 4. 3 How to Use Event Input (page 4-8) F Related parameters "Multi-SP function" "Remote SP enable" (option mode) "Set point" (level 0 mode) "SP mode" (level 2 mode) "Input type" "Scaling upper limit" "Scaling lower limit" "Decimal point" (setup mode) F Option unit E53-AKB Model Alarm value 1 Alarm value 2 Alarm value 3 Conditions of Use Alarms must be assigned as outputs.
