2. Safety and operating instructions

Supplementary information

• This manual is intended as a supplement to already existing documentation (e.g. catalogue, product
information and mounting instruction).

• The manual must be carefully read prior to initial commissioning of the equipment.

Intended purpose of the equipment

• The inclination sensor is a precision sensing device. It is expressly used to determine inclination
angles and to prepare and supply measured values in the form of electrical output signals for the
downstream device. The inclination sensor must not be used for any other purpose.

Commissioning

• The inclination sensor may only be installed and mounted by qualified experts.

• Observe the operating instructions of the machine manufacturer.

Safety precautions

• Prior to commissioning the equipment, check all electrical connections.

• If installation, electrical connection or any other work performed at the inclination sensor or at the

equipment is not correctly executed, this can result in malfunction or failure of the inclination sensor.

• Steps must be taken to exclude any risk of personal injury, damage to operating or corporate
equipment as a result of an inclination sensor malfunction by providing suitable safety precautions.

• The inclination sensor must not be operated outside the limits (see detailed product information).

Failure to comply with the safety instructions can result in malfunctions, personal injury or damage to
property!

Transport and storage

• Only ever transport or store the inclination sensor in its original packaging.

• Never drop the inclination sensor or expose it to major shocks.

Mounting

• Avoid impacts or shocks on the housing.

• The bus cover must fully rest against the base plate when mounted. Any tolerances in assembling the

bus cover onto the base plate may have a negative impact on the absolute inclination angle.

Electrical commissioning

• Do not proceed any electrical modifications at the inclination sensor.

• Do not carry out any wiring work when the inclination sensor is live.

• Never plug or unplug the electrical connection when the inclination sensor is live.

• Make sure that the entire system is installed in line with EMC requirements. Ambient installations and

cabling affect the electromagnetic compatibility of the inclination sensor. Install inclination sensor and
supply cables separately or far away from cables with high interference emissions (frequency
converters, contactors, etc).

• Arrange for separate power supply of the inclination sensor where working with consumers that have
high interference emissions.

• Completely shield the inclination sensor housing and connecting cable.

• Connect the inclination sensor to protective earth (PE) using shielded cable. The braided shield must

be connected to the cable gland or plug. Ideally, aim at bilateral connection to protective earth (PE),
the housing via the mechanical assembly, the cable shield via the downstream devices. In case of
earth loop problems, earth on one side only as a minimum requirement.

Failure to observe these instructions can result in malfunctions, personal injury or damage to property!

3. Profibus-DP

General information

Bus systems are connecting configurations that generate communication between several components.
Profibus DP is a manufacturer-independent open communication system for applications in the fields of
production, process and industrial building automation. It is broken down into three variants:

• Profibus FMS for data communication between controls on the production and process management

level.

• Profibus PA for process engineering applications.

• Profibus DP for fast data exchange between control units and decentralized peripherals in process

automation.

The Profibus system comprises the following device types:

• DP master class 1 (DPM1) is a control for cyclic information exchange with a DP Slave.

• DP master class 2 (DPM2) is a programming or project processing device or operating equipment.

• DP Slave is a peripheral that reads in output data and passes input data onward to a PLC.

The Profibus system is broken down into a monomaster system and a multimaster system by the number
of active masters during the operating phase.

• In a monomaster system, only one master class 1 and the DP slaves are active in the bus.

• In a multimaster system, several masters and the DP slaves are active in the bus. The masters can

optionally either belong to class 1 or class 2.

Profibus-DP is characterized by the following properties:

• Short response times (1 ms with 32 users und 12 MBaud)

• Reliable transmission procedure (Hamming distance 4)

• Availability of a wide range of standardized system components

• Good diagnostic capability

• Simply handling and facility for upgrading

• User-oriented bus system

• Open system

Profibus-DP ist standardized by EN 50170 Vol. 2. This standard defines the communication and user
profiles. User profile for the interface converter is profile 1.1. The user profile is differentiated in relation to
the number of supported functions according device class 1 and 2. Device class 2 provides a greater
number and comprises all the functions of class 1. Parameterization and preset functions are supported
only by class 2. The device supports both class 1 and 2.

GSD file

The device master data file (GSD-file) is a descriptive file describing all required operating data of the
Profibus user. The data itself are also filed in the ROM of the user. The data can be subdivided into two
sections:

• General definitions contain information such as the manufacturer’s name, product name, ident number,

Profibus-specific parameters and baud rates.

• Application-related configurations include information relating to configuration options, parameters,

parameter descriptions, hardware and software status and diagnostic capabilities.
Format and contents are defined in standard EN 50170.
The GSD file’s ident number is 059B for all described products. The GSD file is prior condition for
parameterization and configuration of the inclination sensor by a configuration tool.
