Water Sensor SHT 5006 Fork Sensor

The proven fork sensor with two nickel-plated brass contacts and 6 metres of cable, extendable up to 50 metres, for regularly dry environments: the Schabus water sensor SHT 5006 for Schabus water detectors

The Schabus water sensor SHT 5006 reports water as soon as conductive water connects both contacts at the same time. The two nickel-plated brass contacts are firmly cast in white plastic. The connected Schabus water detector evaluates the connection and immediately triggers the configured response.

Thanks to the wide notch (fork design), the sensor reliably detects genuine leaks, even in environments where biofilms, thin water films or condensation can form. False alarms caused by slight moisture are thus prevented. The compact design is suitable for point monitoring, hard-to-reach places and confined spaces.

The SHT 5006 is an accessory for the Schabus water detectors SHT 5000, SHT 5001 and SHT 5002. The sensor works passively and does not emit its own alarm.

Small, reliable, extendable

The SHT 5006 combines two measuring contacts with a long cable that fits directly onto Schabus water detectors.

What’s in the box

The SHT 5006 is ready for immediate use. The device has no options and no additional variants.

• Fork sensor SHT 5006
• 6 m LIYY control cable, 2 × 0.14 mm², permanently cast
• Mounting material (1 screw, 1 wall plug)
• Operating instructions

How the SHT 5006 is constructed

Contacts, housing and cable form one cast unit. Cast components must not be opened.

How the SHT 5006 detects water

Schabus water detectors work as impedance or resistance measuring devices: if a resistance below 80 kΩ is detected at a sensor input, the device evaluates this as water.

Place, connect, test

Both contacts must be able to be reached by escaping water.

Placement

1. Determine the leak location. Position the sensor where escaping water is expected first, for example under washing machines or dishwashers, at pipelines or on floor surfaces.
2. Align the contacts so that both can be reached by water.
3. Secure the position and cable against unintentional movement.
4. Protect the cable against crushing, tension and sharp edges.

Connection

1. Identify the water detector (SHT 5000, SHT 5001 or SHT 5002). The connection terminals are described in its operating instructions.
2. Connect the two-core cable to the designated sensor input.
3. Carry out extensions and connections suitable for the respective environment and protect them against moisture.
4. Check the entire detection chain: water detection, display, acoustic alarm and intended subsequent function.

Notes on the cable

• Use thin, unshielded LIYY cable, max. 2 × 0.14 mm²
• Total lengths of up to 50 m are possible; the existing 6 m are included
• When connected in parallel, the individual cable lengths are added together
• The maximum permissible cable capacitance is 10 nF
• Never run parallel to 230 V mains cables
• The cable is only briefly water-resistant

Commissioning

1. Visually check fastening, cable and contacts.
2. Deliberately wet both contacts with water. The test must show that water actually reaches the contacts at the installation site.
3. Observe the indication on the water detector and the intended subsequent function.
4. Dry the contacts and mounting surface. Check the return to normal status and, if applicable, the acknowledgement on the water detector.

Manufacturer’s notes

• Read the instructions for the sensor and those of the connected water detector and keep both
• Work on mains voltage may only be carried out by qualified electricians; isolate and verify absence of voltage beforehand
• Never connect low-voltage models to mains voltage
• Do not connect passive water sensors directly to a supply voltage or an electrical load
• Do not continue to use damaged cables or housings; do not open cast components
• Keep packaging material away from children
• The sensor only detects conductive water at its two contacts; for larger areas the sensor cable SHT 5020 is recommended
• It is not a level sensor; for fill levels use mini float switches
• Very pure water and condensate may not be detected reliably
• Specifications for float switches do not automatically apply to electrode sensors

Clean, check, find faults

Cleaning and re-checking

• Clean with a soft, damp cloth
• Do not use solvent-based agents
• Remove deposits from the contacts and dry the sensor
• Repeat the function test after cleaning, changes to the mounting or connection work

Troubleshooting

If the fault persists, put the system into a safe state and contact Schabus Support.

In the event of a service case

1. Describe the fault as precisely as possible: What happened, when does it occur and what does the device display?
2. The manufacturer will examine your enquiry and advise the next steps. Many questions can be clarified by telephone or e-mail.
3. After consultation, pack securely against breakage and enclose a description of the fault, contact details and a copy of the proof of purchase.

The manufacturer cannot accept unpaid shipments. Repairs and maintenance may only be carried out by the manufacturer or authorised specialist personnel.

The SHT 5006 is covered by the statutory warranty of at least 2 years in the EU. The manufacturer Elektrotechnik Schabus additionally offers a 5-year guarantee that can be registered online. Repair and spare parts are available directly from the manufacturer, even beyond the statutory warranty. The device bears the CE mark; the EU declaration of conformity is available for download from the manufacturer.

The SHT 5006 does not belong in household waste. In accordance with Directive 2012/19/EU (WEEE) the device must be collected separately at the end of its service life and recycled in an environmentally sound manner, for example via a municipal collection point for electrical equipment (WEEE Reg. No. DE91394868).
