ICAR by ORTEA NEXT ALL75 mar1912 / 40▲▼: Select step - :Change step status4.3 AUT MODEIn automatic mode, the controller calculates the optimum configuration of capacitor steps in order to reach the set cos.The selection criteria takes into account many variables such as: the power of each step, the number of operations, the totaltime of use, the reconnection time, etc. The controller displays the imminent connection or disconnection of the steps withthe flashing of their identification number (left). The flashing can last in cases in which the insertion of a step is not possibledue to the reconnection time (discharge time of the capacitor). The device initiates automatic corrections when there is anaverage reactive power request (kvar) higher than 50% of the smallest step, and the measured cos is different from thesetpoint.5 MEASURESThe RPC 5LGA controller provides a set of measurements displayed on the alphanumeric display, in conjunction with thecurrent cos that is always displayed on the main display. Press the key to scroll through the measures in rotation.After 30 seconds without pressing any buttons, the display automatically returns to the default measurement defined byP.47. If P.47 is set on the ROT, then the measures rotate automatically every 5 seconds. At the bottom of the list of measuresit is possible to set the setpoint of the cos, acting on the same value set with P.19. Below is a table with the measurementsdisplayed.MEASURE ICON DESCRIPTIONDELTA-kvar Δkvar kvars needed to reach the cosphi setpoint. If delta-kvar is positive cpacitors need to beinserted, if negative to be disconnected.▼ kvar Total kvar of the plant.▲ ΔSTEP Number of equal steps to achieve the target power factor.VOLTAGE V RMS voltage of the plant current.▼ V HI Maximum voltage value measured.CURRENT A RMS current of the plant voltage.▼ A HI Maximum current value masured.AVERAGE PF WPF Weekly average power factor.▼ PF Instantaneous total power factor.THD CAP. THdC Capacitors total harmonic distortion (THD) in current.▼ TC HI Maximum THD value measured.TEMPERATURE °C °F Temperature of internal sensor.▼ °CHI °FHI Maximum temperature value measured.VOLTAGE THD THDV Total harmonic distortion % (THD) of plant voltage.▼▲ VH02… …VH15 % voltage harmonic content from 2.nd up to 15.th orderCURRENT THD THDI Total harmonic distortion % (THD) of plant current.▼▲ IH02… …IH15 % Current harmonic content from 2.nd up to 15.th orderCOS SETPOINT IND CAP Setting of desired cos setpoint (same as P.19).▼▲STEP POWER % Step residual power, as a percentage of the set rated power.▼▲STEP COUNTER OPC Operation counter of the step.▼▲STEP HOURS H Hour meter of the step insertion.▼▲ These measures are shown only if the Step trimming function is enabled (P.25=ON) and the advanced password isenabled and entered.MAN modeiconConnectedstepsManual stepselectionTot kvar inserted inMAN |
