Instructions for use

  • When the instrument is mounted, first it is necessary to dismount its cover and then screw it to the base through the holes and connect the conductors. When manipulating with an open instrument, especially if it is equipped with a display, avoid its damage during the manipulation. After the cover is mounted on again, tighten it well but sensitively so that damp could not penetrate into the instrument.

Diagram

Sensors are connected to the electric circuit in a usual way. They are protected against reversal of poles by a serial diode. ATTENTION when connecting multi-conductor wiring where eg. exchanging of the input and supply conductor can cause damage of the sensor.
A detailed description of all variations of electric connection and mapping of the terminal board and connector outlets, including the description of the communication protocol for serial communication is stated in a special document, click on picture for its enlarge.
