Installing The Sensor - Elektrotechnik Schabus SHT 5002 Notice D'utilisation

4. ASSEMBLY INSTRUCTIONS AND CONFIGURATION
A qualified technician must install the device.

4.1 Installing the sensor

The SHT 5006 water detector (art. no.: 300745) responds to contact with water via two metal
contacts (sensor circuit is closed). You can extend the sensor cable with a dual-core wire (2
x 0.5 mm²) up to 50 metres.
Use our mini float switches for non-conductive liquids:
► ► Mini-float switch made of plastic (art. no. 200940)
► ► Mini-float switch made of stainless steel (art. no. 200941)
4.2 Installation
The SHT 5002 water detector is installed on a 35 mm top-hat rail in a distributor, switch
cabinet or wall-mounted housing.
Instead of 230 V AC operating voltage, you can also operate the SHT 5002 water detector
with 12 – 16 V DC/0.5 A. Use the clamps 5 (+) and 6 (-) for this purpose.
4.3 Level control (2-point controller)
Sensor 1 determines the lower level and sensor 2 determines the upper level. The B1 jumper
is used to define the switching behaviour of the K1 relay.
4.3.1 Filling the container (Fig. page 13) without jumper B1
Water level below sensor 1: K1 relay picked up - pump ON
Water level at sensor 2: K1 relay dropped out - pump OFF
