Wassermelder SHT 5001 – Profi-Gerät für die Hutschiene, 2 Relais

🔌 How is the SHT 5001 powered?

The SHT 5001 can either be with Mains voltage (230 V AC) or with DC voltage (12 V or 24 V DC) If an additional Rechargeable battery or a battery connected, it automatically takes over the power supply in the event of a power failure - the SHT 5001 then acts as uninterruptible emergency power supply (UPS).

The following applies:

• Bei 12 V Akkus hat die Netzspannung Vorrang.
• Bei 24 V Akkus hat der Akku Vorrang.
• Die Umschaltgrenze liegt bei ca. 15 V.

🧪 Which sensors can I connect – and when do I use which?

The SHT 5001 supports two types of sensors:

• Wassersensoren sind ideal für regelmäßig trockene Umgebungen, wie unter Waschmaschinen, Spülmaschinen oder in Technikräumen. Sie erkennen Wasser auf ebenen Flächen zuverlässig, sollten aber nicht dauerhaft feuchter Umgebung ausgesetzt sein, da sie mit der Zeit verschleißen können.
• Mini-Schwimmerschalter eignen sich für dauerhaft feuchte Zonen, zur Pegelüberwachung, bei nicht leitfähigen Flüssigkeiten oder in Brunnen, Schächten, Tanks etc. Sie sind verschleißfrei und wartungsarm.

Recommendation: If technically possible, should always be used Mini float switch are used - they are significantly more robust and durable.

📏 How long can the cables to the sensors be?

The cable lengths differ depending on the sensor type:

• Wassersensoren: bis 100 m
• Mini-Schwimmerschalter: bis 300 m

The prerequisite is that only unshielded LiYY cables with 2×0.14mm² be used. The maximum line capacity may be 10nF per line do not exceed. It is also important that the lines not parallel to 230V power lines be relocated to avoid disruptions.

🔁 What does alarm memory mean – and how does it work?

Via a simple Wire bridge in the device Alarm memory activate. In this operating mode, a triggered alarm remains stored permanentlyUntil it is actively reset - e.g. B. via the reset button on the front or via a externally connected button (potential-free contact at input Q, terminals 10/11).

The memory function becomes not activated, the alarm goes off automatically as soon as water is no longer detected.

The SHT 5001 offers this function separately for each of the two reporting lines – for maximum flexibility.

🔉 How is the alarm signaled?

In the event of water contact or the level is exceeded, the SHT 5001 gives:

• einen akustischen Warnton über den internen Piepser aus,
• und aktiviert ein Wechselrelais, das externe Geräte schalten kann (z. B. Pumpen, Alarme, Hausautomation).
• Zusätzlich steht ein Alarmausgang mit 12 V / 30 mA zur Verfügung – z. B. für Signal-LEDs, Blitzleuchten oder externe Sirenen.

Release both signaling lines separate relays off, the buzzer and the alarm output apply together to both lines

🛠️ How many sensors can I connect per line?

can be used per signaling line two sensors connect – one to each:

• dem Eingang für Wassersensoren,
• und dem Eingang für Mini-Schwimmerschalter.

So every line is can be assigned twice, each with its own evaluation and relay control.

💬 What happens if I detect water - but the alarm doesn't go off?

In this case the Memory function active be. A saved alarm remains in placeUntil it is reset manually - using the reset button or an externally connected button. If necessary, check the position of the wire jumper in the device.

If there is no more water, but the alarm still goes off does not reset automatically, it is most likely because the Memory function switched on became
