Synchronization and Frequency / Voltage Control Unit SYFU50

Analog output (SYFU50-G004)Mode 0: Output of the frequency difference Fgen. – Fnet (ranges and values please look to technical data).Mode 1: Output of the frequency difference Fcurrent – F rated related to the rated value. During beginning ofsyncronizing the rated frequency value is be set to +1/2 * Fdiff ( setted difference frequency ). During islandrunning mode the rated frequency is equal to the nominal frequency F-Nenn.Mode 2: Analog output like Mode 1 but without the functions of output relais for frequency control.Other FunktionsWith INH-Input 16-17 the synchronizing function can be suppressed by distancy on-switching a 24V DC voltage.All functions especially voltage and frequency control remain activ, only the syncronizing relay cuts off.Should of any reason a failure arise (program crash) a reset is possible with pushing all 3 keys at a time. Afterreset the display shows short times “DSL-electronic” and the unit works immediately. A full reset is obtainedwith off and on switching of auxiliary voltage. A faillure only on display do not lead to faillures of controllingfunctions.Circuit Diagram for L- N connectionE0SYFU50-20120614 © Copyright 2012 by DSL electronic ® GmbH, Germany subject to changeSeite 4 - 7
