Reactive Power Controller Operating instructions

Reactive Power ControllerLearning of the configurationAfter installation of thecontroller there is thepossibility to learn andsave the configurationlearnwith the function"learn".Important requirements are:- The discharge time for capacitors is set to 60 seconds,when the device is delivered. For capacitors with longerdischarge times, the discharge time must be checkedand changed before using the "learn" function.- The current transformer must be flown through byconsumer and compensation current.- The measurement and supply voltage may not be takenfrom phase to N.- The compensation system must be ready for operation.The learning function of the controller is devided intotwo steps:Step 1 - Learning of the connection configurationHere the correction angle between current transformerand measurement and supply voltage is detected.Step 2 - Learning of the capacitor stagesHere the number of outputs and the stage power ofeach stage is detected.The following requirements are neccessary:- The switching of a capacitor stage must cause a changeof current of at least 50mA at current input.- The stage power of the stage to be learned must bebigger than 1% of the measuring range of the controller.Start learningGo to symbol learn usingkey 1.Select action (oFF, 1,2, 3) with key 3.learnStart learning with key1.The symbol learn flashes. The controller learns.During the learning the capacitor stages are switchedfor several times. The learning can only be interruptedby switching off the power factor controller.The duration of the learning procedure depends on thenet conditions, the number of capacitor stages and theset discharge time for the capacitors.When the learning procedure is finished, the detectedcorrection angle, in theexample 270°, is indicated.The learned characteristicsareProgsaved.After 60 seconds the controller changes to automaticmode. Pressing key 1 for 2 seconds, you reach automaticmode at once.Attention!After learning, the saved configurations must be checked,if they are plausible.Attention!After learning, the saved configurations must bechecked, if they are plausible.The following actions can be carried out:oFF - No learning.1 - Step 1, learning of the connection configuration.2 - Step 2, learning of capacitor stages.3 - Step 1 + 2, learning of the connectionconfiguration and capacitor stages.= Key 1 = Key 2 = Key 3Page 21
