Häufig gestellte Fragen

Was unterscheidet den RLSW8 LCD vom RLSW5A und welche Microcontroller-Vorteile bietet er?

RLSW8 = Microcontroller-basiert mit 10-Punkt-LCD-Menü, 10-LED-Kette, T1/T2-Taster-Bedienung vs. RLSW5A nur Potentiometer. Intelligente Funktionen: Dimensionsumstellung m/s↔m³/h↔l/min, Alarm-Hysterese, Kalibrierfaktor-Anpassung, NO/NC-Schalt-Konfiguration. Selbstüberwachung: Sensor/Elektronik/Kabel kontinuierlich überwacht mit Error-Codes.

Welche Extreme-Temperatur-Optionen bietet der RLSW8 und für welche Anwendungen?

Standard: -25...80°C für normale Industrieanwendungen. Option 1: -25...250°C für abgesetzten M8-Sensor. Option 2: -25...350°C für Extremanwendungen. Anwendungen 350°C: Abgasmessungen, Brennkammer-Überwachung, Hochtemperatur-Extrusionsprozesse, Ofenabgas-Kontrolle, Hochtemperatur-Prüfstände. Sensor-Material: Edelstahl 1.4571 bei Extremtemperaturen, MS58 vernickelt Standard. Einziger Microcontroller-Luftstromsensor für 350°C am Markt.

Wie funktioniert das M8-Sensor-System beim RLSW8 und welche Installation-Vorteile bietet es?

M8-Stecker-System: Abgesetzter Sensor mit 2,5m Industrial-Kabel (nicht veränderbar wegen Kalibrierung), M8-Steckverbindung mit Zugentlastung. Vorteile: Flexible Sensor-Platzierung, Schaltschrank-Installation getrennt von heißer Sensorposition, einfache Wartung, Temperaturen bis 250/350°C möglich. Paarige Kalibrierung: Sensor + Gerät werksseitig abgestimmt - niemals tauschen! Spezial-Montageset: Erforderlich für ordnungsgemäße Installation, bei Bestellung angeben.

Welche intelligenten Display-Features bietet der RLSW8 LCD?

10-LED-Kette: Prozentuale Strömungsanzeige in 10%-Schritten (z.B. 3 LEDs = 30% bei 10 m/s max = 3 m/s aktuell). Schaltpunkt-LED: Blinkt 2×/Sekunde zur Anzeige des eingestellten Schwellenwerts. LCD-Umschaltung: T2-Taster für absolute/relative Anzeige, Flow/Temperatur-Wechsel. Überlast-Anzeige: Rechte LED blinkt schnell bei >100% - Anpassung "Geschw. Max" erforderlich. Multi-Language: Deutsch/Englisch über Menü umschaltbar.

Wie erfolgt die Menü-Programmierung beim RLSW8 und welche Parameter sind einstellbar?

T1/T2-Taster-Navigation: T1=Continue, T2=Select für 10-Punkt-Menü. Parameter: 1.Language, 2.Geschw dim (m/s/m³/h/l/min), 3.Geschw max, 4.Rohr Durchm, 5.Alarm (Pot/flow%), 6.Alarm hyst, 7.Alarm verz, 8.Start verz, 9.Kal fakt, 10.RelaisFkt (NOP/NOC). Kritisch: "Speichern und beenden" verwenden - sonst Datenverlust! Dimensionsumstellung: Messbereich/Schaltpunkt nach Umstellung neu justieren erforderlich.

Welche Ausgangs-Konfigurationen bietet der RLSW8 für SPS-Integration?Welche Selbstüberwachung-Funktionen bietet der RLSW8 für Betriebssicherheit?

Triple-Überwachung: Sensor + Sensorelemente + Anschlussleitungen kontinuierlich auf Kurzschluss/Drahtbruch. Error-Code-System: Fehlercodes im LCD + LED-Anzeige bei Störungen. Fail-Safe-Verhalten: Alle Ausgänge (Relais/Analog) fallen bei Fehler ab. Reset-Prozedur: 4s Netzunterbrechung löscht gespeicherte Fehler. Bereitschaftszeit: 25s Aufwärmzeit mit Statusanzeige "starte 10s, Version xxx" im LCD. Industrie 4.0-ready: Proaktive Wartung durch Fehlerprotokoll.

Welche Selbstüberwachung-Funktionen bietet der RLSW8 für Betriebssicherheit?

SPNO-Relais: 200V AC/DC, 1A (Klemmen 8/9) als Schließer standard, NOP/NOC über Menü konfigurierbar. NPN Open Collector: 250mA max., nicht leitend bei Strömung für SPS-Eingänge. Dual-Analog: 0-10V (Ra=0,4kΩ) + 4-20mA (Ra=0,4kΩ) parallel für Regelung/Visualisierung. ACHTUNG: Klemme 2+5 niemals brücken! Mindestschaltleistung: 10mA/5V DC für sichere SPS-Ankopplung.

Für welche Premium-Anwendungen ist der RLSW8 besonders geeignet?

Hochtemperatur-Prozesse: Extrusionsanlagen, Brennkammer-Überwachung, Abgasmessungen bis 350°C. SPS-Integration: Prozessvisualisierung, Regelungstechnik mit Analog-Ausgängen. Forschung/Entwicklung: Prüfstände, Motorentests, Abgasuntersuchungen mit Datenlogging. Qualitätssicherung: Filterüberwachung, Reinraum-Kontrolle mit Error-Code-Protokollierung. Building Automation: DDC-Anlagen mit LCD-Anzeige vor Ort, Fernüberwachung via Analogwerte.
