Installation position - Sensing range 360°
The inclination sensor featuring a 360º sensing range must be
installed in a way that the X-axis as in the illustration is in parallel
alignment with gravity. The deflection may not be more than ±3º.
Please note that the inclination sensor must fully and evenly rest
on the contact surface and whilst inclination/rotation must not be
subject to any misalignment in the X- or Y-direction since this
would affect the sensing accuracy.
The 360° inclination sensor default position is 0° as shown in the
following illustration but may be optionally configured by help of
the preset function.
The measuring direction may also be inverted. Default parameter
of the inclinometer’s sensing direction is clockwise from 0...360°,
in case of active inversion counter-clockwise.
7.2. Electrical connection
The inclinometer must fully rest on the base plate and be firmly screwed in place.
For e-connection of the bus cover please proceed as follows:
• Release both fastening screws of the bus cover
• Carefully loosen the bus cover and lift off from the base plate in the axial direction.
7.2.1. Setting the user address (Node ID)
The user address (Node ID) is set decimally using two rotary switches in the bus cover. The maximum
number of user is 99. The address is read in once only on Power ON.
• Setting the user address decimally using rotary switches 1 and 2 (Default 00).

7.2.2. Terminating
resistor
If the connected Profibus user is the final device in the bus line the bus must be terminated by a resistor.
The required resistors are integrated in the inclination sensor and are activated by a two-pole DIP switch.
• The final user must set the internal terminating resistors to „ON“ using the 2-pole DIP switch (default
OFF).
