Häufig gestellte Fragen - WiMeter-S Sungrow

Wie installiere ich den WiMeter-S?

Der WiMeter-S wird auf eine 35-mm-DIN-Schiene montiert. Schließen Sie die Antenne an, befestigen Sie die Antenne außerhalb des Schaltschranks und verbinden Sie die Stromkabel mit den Klemmen L und N. Der CT-Sensor muss um den Phasenleiter (L) gelegt werden, wobei der Pfeil vom Netz zur Last zeigt.

Welche LED-Anzeigen gibt es und was bedeuten sie?

Es gibt fünf LEDs: RUN (grün): leuchtet bei Stromversorgung, blinkt bei Normalbetrieb; COM (rot): blinkt bei normaler interner Kommunikation, leuchtet dauerhaft bei Störung; NET (blau): leuchtet bei Verbindung mit WiNet-S2, blinkt bei Datenübertragung; PWR/COM (gelb): leuchtet bei normaler interner Stromversorgung, blinkt bei Kommunikation; 1000 imp/kWh (rot): blinkt bei Erkennung von Wirkleistung.

Wie verbinde ich den WiMeter-S mit dem WiNet-S2?

Drücken Sie die Funktionstaste am WiNet-S2 für 5–10 Sekunden, bis die RUN-LED grün blinkt. Wiederholen Sie dies am WiMeter-S. Beide müssen innerhalb von 2 Minuten in den Netzwerkmodus versetzt werden. Nach erfolgreicher Verbindung blinkt die NET-LED blau.

Was tun, wenn der WiMeter-S offline ist?

Prüfen Sie die COM- und NET-LED. Leuchtet COM dauerhaft, ist die interne Kommunikation gestört (überprüfen Sie die 485-Anschlüsse). Blinkt COM, prüfen Sie die NET-LED: Ist NET aus, liegt ein Netzwerkproblem vor (siehe nächste Frage). Leuchtet NET dauerhaft, warten Sie einige Minuten; bei wiederholtem Offline-Wechsel ist die Funkverbindung schlecht – überprüfen Sie die Antenne.

Der Netzwerkverbindungsversuch schlägt fehl – was kann ich tun?

Stellen Sie sicher, dass der WiMeter-S mit Strom versorgt wird und die Antenne korrekt angeschlossen ist. Überprüfen Sie die blaue WLAN-LED am WiNet-S2: blinkt sie schnell, ist EasyConnect aktiv – drücken Sie die Taste 3x, um es zu deaktivieren. Prüfen Sie die NET-LED am WiMeter: ist sie aus, drücken Sie die Taste für 5–10 s, um den Netzwerkmodus zu starten. Falls das WLAN-Signal schwach ist, verwenden Sie einen WiFi-Extender.

Kann der WiMeter-S für Abrechnungszwecke verwendet werden?

Nein, der WiMeter-S ist ein reines Messgerät zur Erfassung elektrischer Werte am Netzanschlusspunkt. Die gesammelten Daten können von denen des Hauptzählers abweichen und sind nicht für Abrechnungszwecke geeignet.

Welche Sicherheitshinweise muss ich beachten?

Der WiMeter-S darf nur in trockener Umgebung verwendet werden. Vor der Reinigung ist das Gerät vom Stromnetz zu trennen. Es muss ein externer Trennschalter nahe am Gerät installiert werden. Die Leitungsschutzsicherung oder der Leitungsschutzschalter darf maximal 100 A betragen. Jegliche Modifikation ist untersagt.

Welche Umgebungsbedingungen sind für den Betrieb zulässig?

Betriebstemperatur: -30 °C bis 60 °C, relative Luftfeuchtigkeit ≤ 95 % (nicht kondensierend), maximale Betriebshöhe 4000 m. Schutzart IP20, nur für Innenräume.

Wie reinige ich den WiMeter-S?

Vor der Reinigung das Gerät vom Stromnetz trennen und sicherstellen, dass es spannungsfrei ist. Verwenden Sie ausschließlich ein trockenes Tuch. Keine Flüssigkeiten oder Reinigungsmittel verwenden.

8 Troubleshooting

Device	No.	Fault name	Corrective measures
WiMeter-S	1	Meter offline	Check the COM indicator and the Net indicator of the WiMeter-S:If the COM indicator is always on, communication between the WiMeter-S and the meter is abnormal. Check the 485 connections inside the WiMeter-S.If the COM indicator blinks, communication between the WiMeter-S and the meter is normal. Further check the Net indicator.If the Net indicator is always off, the networking is abnormal. Refer to the corrective measures of abnormal networking.If the Net indicator is always on, wait for a few minutes to see if the meter can come back online. If so, there is no abnormality. If the meter goes repeatedly online and offline, the wireless communication quality is poor, causing serious packet loss. Please check whether the wiring of the WiMeter-S antenna is normal and whether it has been moved.
	2	Abnormal networking	(1) Check whether the WiMeter-S is normally powered on.(2) Check whether the wiring of the WiMeter-S antenna is normal and whether it is moved.(3) Check the blue WLAN indicator on the WiNet-S2:If it blinks quickly, EasyConnect mode is enabled. Press the button 3 times quickly to exit the EasyConnect mode and check whether the networking is normal 2 mins later;(4) Check the blue Net indicator on the WiMeter-S:If it is always off, the WiMeter-S is not connected to any hot spot. Press the button for 5 - 10 s and check whether the networking is normal.If it is always on or blinks slowly, the WiMeter-S is connected to other device's hot spot rather than WiNet-S2's. Press the button for 5 - 10 s and check whether the networking is normal.(5) Check that the WiNet-S2 hot spot can be connected at the WiMeter installation location. Try to connect a computer or a mobile phone to the WiNet-S2's hot spot.If the connection fails, the WiNet-S2's hot spot has been connected by two other people. Disconnect other connections and check whether the networking is normal 2 mins later.If the hot spot of WiNet-S2 cannot be searched or the hot spot signal is weak, it is recommended to use WiFi Extender to boost the signal. Press the button for 5 - 10s and check whether the networking is normal. For more information on the use and installation of WiFi Extender, please contact SUNGROW Customer Service Centre.
