2 Product Description
2.1 Use and Application
INX***DH-F199-B30-*** and INY***DH-F199-B30-*** series inclination sensors detect and
measure the tilt angle (inclination/slope/elevation) of an object in relation to the force of gravity.
The basic principle behind these inclination sensors is a microelectromechanical systems
(M MS) sensor cell that is embedded in a fully molded application-specific integrated circuit
(ASIC). The angle is measured by the relative change in electrical capacitance in the M MS
cell.
INX***DH-F199-B30-*** sensors are 1-axis sensors that detect and measure the tilt around the
x-axis.
INY***DH-F199-B30-*** sensors are 2-axis sensors that detect and measure the tilt around the
x-axis and the y-axis.
Communication with the inclination sensors, such as configuration and data output, occurs via
a MODBUS RTU interface.
MODBUS RTU Interface
MODBUS RTU is an open serial (RS-232 or RS-485) protocol that is based on master/slave
architecture. It is a widely accepted protocol due to its ease of use and reliability. MODBUS
RTU messages are simple and, therefore, reliable. Due to this simplicity, the basic 16-bit
MODBUS RTU register structure can be used to pack in floating point, tables, ASCII text,
queues, and other unrelated data.
The MODBUS application protocol defines a simple protocol data unit (PDU) independent of
the underlying communication layers: The mapping of MODBUS protocol on a specific bus or
network introduces some additional fields on the PDU. The client that initiates a MODBUS
transaction builds the MODBUS PDU and then adds fields to build the appropriate
communication PDU.
Figure 2.1
On the MODBUS serial line, the address field only contains the slave address. The valid slave
node addresses are in the range of 0 ... 247 decimal. The individual slave devices are assigned
addresses in the range of 1 ... 247. A master addresses a slave by placing the slave address in
the address field of the message. When the slave returns its response, it places its own
address in the response address field to let the master know which slave is responding

3.1 Instructions for Mechanical and lectrical Installation
Observe the following instructions to ensure safe operation of the inclination sensor:
Warning!
Work must only be performed by trained and qualified personnel.
Commissioning and operation of this electrical equipment must only be performed by trained
and qualified personnel. This means individuals who are qualified to commission (in
accordance with safety technology), connect to ground, and label devices, systems, and
circuits.
Warning!
Only perform work when the system is in a de-energized state.
De-energize your device before performing work on the electrical connections. Short circuits,
voltage peaks, and similar events can lead to faults and undefined statuses. This presents a
significant risk of personal injury and property damage.
Warning!
Check electrical connections before switching on the system.
Check all electrical connections before switching on the system. Incorrect connections present
a significant risk of personal injury and property damage. Incorrect connections can lead to
malfunctions.
Caution!
Do not remove the housing.
Do not remove the sensor housing under any circumstances, as damage and contamination
can occur as a result of taking improper action.
Caution!
Do not perform any electrical modifications.
It is not permitted to perform electrical modifications on the inclination sensor. If you open or
modify the device yourself, not only are you endangering yourself and others but you will also
void any warranty and absolve the manufacturer of any liability.
Do not allow the inclination sensor to fall or be exposed to mechanical load.
Do not make any alterations to the housing of the inclination sensor.

3.2 Mounting Instructions
The inclination sensors are pre-calibrated devices that can be put into immediate operation
following easy installation with a three point mount. The mounting surface must be flat and free
of dust and grease.
Depending on the sensor model, pay attention to the correct orientation of the sensor for
inclination measurement when mounting.
The following figures show the correct axis orientation for each model.
Figure 3.1 1-axis sensor
The figure shows the correct axis orientation for a 1-axis sensor with one connector. There are
also models with two connectors.
Figure 3.2 2-axis sensor
The figure shows the correct axis orientation for a 2-axis sensor with two connectors. There are
also models with one connector.
Fastening with Screws
We recommend hexagon head screws with M6 or UNC 1/4 for the best possible and most
secure mounting. Use all three screws for mounting. Restrict the tightening torque to the range
of 10 Nm ± 10 % for the screws. The M12 connectors are to be perfectly aligned and screwed
to the end with a tightening torque in the range of 0.4 ... 0.6 Nm. Use all three screws for
mounting, and use the same tightening torque for all the screws.

Installation
3.3 lectrical Connection
The sensors are connected via M12 x 1, 5-pin connectors with MODBUS RTU. There are
sensor models with one connector (V15) or two connectors (2V15).
One-connector sensors have a male connector.
Connecting the sensor to voltage
Connect the operating voltage to pins 2 and 3 of the 5-pin connector.
3.4 Configuring/Connecting the Terminator
To ensure a secure signal transfer, both ends within a MODBUS RTU segment must be closed
with a 120 Ω terminator. If the inclination sensor is installed at the beginning or the end of the
MODBUS RTU, a terminator must be used. The inclination sensor is equipped with a built-in
terminator to be activated/deactivated by setting the correct register (See chapter 4.4). It is also
possible to use an external terminator, which can be more suitable in some cases.
The bus wires can be routed in parallel or twisted, with or without shielding, in accordance with
the electromagnetic compatibility requirements. A single-line structure minimizes reflection.
