SHT 262 Water Detector – 230V Plug-in Unit

The Aquastop with sensor cable: detect water over a large area, switch off the appliance, prevent damage

The Schabus Aquastop SHT 262 is a plug-and-play water detector with sensor cable and automatic appliance shut-off. It is inserted between the wall socket and the appliance, for example in front of a washing machine, dishwasher or aquarium pump. As soon as the sensor cable comes into contact with water, it warns acoustically and optically and switches off the connected appliance.

Unlike a fork sensor, the sensor cable reacts over its entire length. It detects water over an area and not just at a single point, for example puddles under fitted kitchens, bathroom furniture, aquariums, pipes, baths and tanks. The cable is simply laid out on the floor.

Via the switchable socket, a normally closed solenoid shut-off valve can also be controlled, which interrupts the water supply in the event of water ingress. The device is intended for use in residential areas, commercial and business premises as well as small businesses.

Detect, warn, switch off

The SHT 262 combines an area-measuring sensor cable with acoustic and optical alarm and automatic appliance shut-off.

How the SHT 262 is constructed

A compact socket device, a short control cable and the sensor cable: the three parts together form the protection system.

How the SHT 262 works

The alarm remains until the Aquastop is disconnected from the mains and the water is no longer in contact with the sensor cable.

Lay the sensor cable, put the Aquastop into operation

Installation is plug-and-play. A specialist company is only required for the solenoid shut-off valve.

Laying the sensor cable

Commissioning

1. Plug the Aquastop into a socket with 230 V AC and 50-60 Hz.
2. Plug the mains plug of the washing machine, dishwasher or other appliance into the Schuko socket of the SHT 262. The mains plug lock prevents accidental unplugging.
3. The LED lights up green: the device is ready for operation.
4. Lay the sensor cable flat and then perform the function test.

Extending the cable and sensor cable

There are two cables with different rules. The total length of both cables together should not exceed 50 m.

• LIYY control cable (white, 1 m): extendable up to 50 m with a LIYY cable (max. 2 x 0.14 mm²) and terminals. To do this, cut the existing cable and reconnect it with terminals.
• Matching control cable: available by the metre (Art. No. 300780). The desired length can also be specified directly when ordering.
• Sensor cable (black-and-white, 2 m): extension only from the factory to the desired length, maximum 50 m. Subsequent extension is not possible.
• Contact: The manufacturer will be happy to assemble your device with the desired cable length from the factory.

Check the function and act correctly in the event of an alarm

Perform the function test monthly for your safety.

How to test the SHT 262

1. Touch the sensor cable with a cloth soaked in water.
2. The alarm is triggered immediately and the connected appliance is switched off.
3. Remove the cloth from the sensor cable.
4. Briefly disconnect the Aquastop from the mains. The alarm switches off again.

Behaviour in the event of an alarm

1. Eliminate the cause of the water leak.
2. Remove the water from the sensor cable. The cable must no longer be in contact with water.
3. Briefly disconnect the Aquastop from the mains and plug it in again.
4. The LED lights up green: the connected appliance can be put back into operation.
