1. Safety instructions
1.1 Range of application AUMA actuators are designed for the operation of industrial valves, e.g.
globe valves, gate valves, butterfly valves and ball valves. For other applications, please consult us. The manufacturer is not liable for any possible damage resulting from use in other than the designated appli
­cations. Such risk lies entirely with the user. Observance of these operation instructions is considered as part of the controls’ designated use.
1.2 Commissioning (electrical connection)
During electrical operation, certain parts inevitably carry lethal voltages. Work on the electrical system or equipment must only be carried out by a skilled electrician himself or by specially instructed personnel under the control and supervision of such an electrician and in accordance with the applicable electrical engineering rules.
1.3 Maintenance The maintenance instructions must be strictly observed, otherwise a safe
operation of the multi-turn actuator/ the controls is no longer guaranteed.
1.4 Warnings and notes Non-observance of the warnings and notes may lead to serious injuries or
damage. Qualified personnel must be thoroughly familiar with all warnings and notes in these operation instructions. Correct transport, proper storage, mounting, and installation, as well as careful commissioning are essential to ensure a trouble-free and safe operation. The following references draw special attention to safety-relevant proce­dures in these operation instructions. Each is marked by the appropriate pictograph.

4. General information about Profibus DP
For the exchange of information among automation systems and between automation systems and the connected decentral field devices, serial field­buses are mainly used today as the communication system. Thousands of applications have proved impressively that cost savings of up to 40 % in wiring, commissioning, and maintenance are achieved by using fieldbus technology. While in the past the fieldbuses used were often manufacturer specific and incompatible with other bus systems, the systems employed today are almost exclusively open and standardized. This means that the user does not depend on individual suppliers and can choose the best product at the most competitive price. Profibus DP is the leading open fieldbus system in Europe, which is also used successfully throughout the world. The application range includes automation in the areas of manufacturing, processing and building. Profibus DP is an international, open fieldbus which has been standardized in the fieldbus standard EN 50 170. This standardization ensures that the invest­ments of manufacturers and users are protected to the best possible degree and the independence of the manufacturer is guaranteed. These operation instructions cannot provide a general introduction into Profibus DP. For more information, please refer to the literature references in appendix D.
4.1 Basic characteristics Profibus DP defines the technical and functional features of a serial fieldbus
system allowing the interconnection of distributed, digital automation devices. Profibus DP distinguishes between master and slave devices. Profibus DP is designed for fast data transmission on the field level. Here, central control devices, such as a PLC or PC, communicate via a fast serial connection with peripheral field devices such as input/ output devices, valves, and actuators. The interchange of data among the field devices is realised on a cyclic basis. The respectively necessary communication functions are established by the Profibus DP basic functions according to EN 50 170.
Master devices control the data traffic on the bus. A master is allowed to send messages without an external request. Masters are also called ‘active devices’ in the Profibus protocol.
Slave devices such as AUMA Profibus DP actuators are peripheral devices. Typical slave devices are input/ output devices, valves, actuators and measuring transmitters. They do not have bus access, i.e. they may only acknowledge received messages or, at the request of a master, transmit messages to that master. Slaves are also called ‘passive devices’.

Operation instructions Profibus DP
4.2 Basic functions of Profibus DP
The master reads the input information from the slaves cyclically and writes the output information cyclically to the slaves. In addition to this cyclic data transfer of the process representation, Profibus DP also provides powerful functions for diagnostics and commissioning purposes. The data traffic is monitored through the monitoring functions on the master and slave side.

Check whether type of current, supply voltage, and frequency correspond to motor data (refer to name plate at motor).
.
Loosen bolts (50.01) (figure D-1) and remove plug cover.
.
Insert cable glands with “EEx e” approval and of size suit­able for connecting cables. For the recommended cable glands refer to appendix E, page 54. (The enclosure protection stated on the name plate is only ensured if suitable cable glands are used).
.
Seal cable entries which are not used with suitable plugs.
.
Maximum 2 wires with the same cross section may be con­nected to one terminal.
.
Remove cable sheathing in a length of 120 – 140 mm. Strip wires: Controls max. 8 mm, motor max. 12 mm.
For stranded wires use end-sleeves according to DIN 46228.
.
Connect bus cable. Refer to figures (D-4 or D-5). The termination resistor for channel 1 is connected through linking the terminals 1 – 4 and 3 – 2 (standard). Only connect the termination resistor if the actuator is the final device in the Profibus segment.
.
Connect screen largely to the cable glands. For the recommended cable glands refer to appendix E, page 54.
If the actuator must be taken from the valve, e.g. for service purposes, it can be separ
ated from the mains without having to remove the wiring (figure D-2). For this purpose, the screws (51.02) are removed and the plug/ socket connector is pulled off. Plug cover (50.0) and terminal board (51.0) remain together.
Flameproof enclosure! Before opening, ensure that no explosive gas and no voltage is present.
A special parking frame (figure D-3) for protection against touching the bare contacts and against environmental influences is available.
