LV850013 Digitales Modul Über/Unterfrequenz ANSI

Digitales Modul Über/Unterfrequenz ANSI 81. Überwachung der Netzfrequenz am Micrologic X, Auslösung bei Über/Unterschreitung der vorgegebenen Werte. Über- und Unterfrequenzschutz ist bestens geeignet für Generatoreinspeisung. Die permanente Überwachung der Frequenz ermöglich geeignete Massnahmen, um die Betriebskontinuität in aussergewöhlichen. oder kritischen Zuständen sicherzustellen, z.B. Lastabwurf, Netzumschaltung, Generatorstart. The upload of the digital modules is made without interrupting power, using EcoStruxure Power Commission software and a USB cable. This digital module is used to generate either an alarm or a trip for under frequency and over frequency protections. The protection picks up when the frequency reaches its upper or lower limit. The Under/Over frequency protection requires the Micrologic X control unit to be supplied by an external 24 V dc power supply. The Micrologic X control unit firmware (greater than or equal to V003.012.xxx) is compatible with this digital module. Earlier firmware versions need to be upgraded. The benefit is to provide under frequency and over frequency protections that are suitable for generator use during abnormal or critical situations (load shedding, source changeover, emergency generator starting).
