GENERAL The new generation of reactive energy controllers PR-2D, in the 3, 6 and 12 steps version, offer the user, exce-llent advantages of use, facilitating the calculation of the parameters which determine their performance and additionally compensating for the possible errors in the electrical connections. The following may be generally considered: The current transformer must be connected at R phase. Օ Tension must be measured between R - S phases. It does not require adjustments, since the one for sensibility (C/K) is automatic and that of the cosine Տ ispreset to the unit value. Օ It detects...

PROCEDURE Before starting the controller, you must verify that network is with enough loads (around 50%). The reason isthat network does not become capacitive during checking. The phase sequence must be correct. Initial Reset: Press simultaneously the buttons UP(+), DOWN(-) and ENTER during enough time until displayshows 8.8.8 and all service leds light (except the leds which indicate the connected steps) and release the but- tons when it happens. With this action the controller is reset. Phase-Phase connection (if the Phase-Neutral connection is desired, set nպ.1 switch position in OFF) Circular...

AUTOMATIC PERFORMANCE OF THE CONTROLLER Once the previous steps have been carried out, "AJU" will appear on the display. This indication signifies thatthe controller is ready to start the internal calculation process. After 25 seconds have elapsed, cycled are commenced by the controller for data intake. Cycle n1. The controller shall identify the connections made by the user (current transformer and referencevoltage), commencing an automatic sequence of five operation, consisting in connecting-disconnecting one or various steps in each operation, each of them remaining indicated in the display...

SEMI-AUTOMATIC PERFORMANCE OF THE CONTROLLER For a semi-automatic performance of the controller, the current transformer and the reference voltage musthave their electrical connection suitably connected to the device (see connection diagram). With this performan- ce modality, it will not be possible to discover the current direction in the 4 quadrants. In order to enter this performance modality, activate simultaneously, the 3 buttons ( up, down and enter) untilthe previously described initial cycle starts. When the display indicates "A.1" ( automatic mode) active the "up" button to pass into...

2.- Current Transformers with the sum of currents. In case of using a current transformer for the sum of various currents, the ratio of the transformation of the dif-ferent current transformers must be summed up.Example:- 1 Current transf. K1= 500/5- 2ں Current transf. K2= 500/5K = K1 + K2 = 500/5 + 500/5 = 200 Network voltage 400V Phase / Phase.6 capacitor steps with a power per step of 50 KVAR. Transformation ratio of the current transformer 1000/5 AK = 1000/5 = 200C = 50 KVARC/K = 50/200 = 0.25Response sensitivity: 1 x 0.25 = 0.25ARecommended:a) In case that C/K value lower than 0.1 AHighest...
