► Do not connect loads of low resistance (e.g. lamps) directly to the sensor.

Switch these loads via a relay (→ fig. 6):

► For inductive loads a RC circuit

should be connected in parallel to the

load (→ fig. 7).

► A load which is too low for 2-wire

sensors may lead to malfunction.

In such a case a resistor should be

connected in parallel to the load

(→ fig. 8).

• For series connection consider the voltage drop of each unit.
