Mercedes-Benz MBN 9666-3 Company standard Date published: 2020-07 Transition period: 0 months Total no. of pages (including annexes): 60 Person in charge: Oliver Zeller E-mail: [email protected] Plant: 010; Dept.: PT/TSD Phone: +49 160 8605757 Date of translation: 2020-08 Construction of and Specifications for Production Equipment, Components, Machines, Systems, Facilities, and Devices Part 3: Electrotechnical equipment, supplement to DIN EN 60204-1 (2019) Foreword The basis of MBN9666-3 is formed by DIN EN 60204-1 (2019). The chapter reference is therefore 1:1. The chapter headings from DIN EN 60204-1 are underlined. Headings that are not underlined are supplements to MBN9666-3. If no content is available, the content of DIN EN 60204-1(2019) shall apply. All requirements described therein ─ including passages of a recommendatory nature and proposals ─ shall be implemented. If content is available in MBN 9666-3, it is supplementary, represents a selection made from the possibilities offered by DIN EN 60204-1 or prohibits a specific design version. The specifications for implementation and components are supplemented by the other MBN9666 regulations. Refer to DIN 820-2 for verb forms and equivalent expressions. This edition supersedes the former edition of this Standard. A list of all document parts of the MBN 9666 series can be found in DocMaster. Application note: MBN 9666 can be referenced in its entirety by indicating the standard number "MBN 9666 (all parts)" without mentioning the part document, or a part document can be referenced individually, e.g. as "MBN 9666-1". Changes In comparison with edition 2015-04, the following changes have been made: Align the chapter structure with that of DIN EN 60204-1. Update to specifications due to technical developments. Corrections to assignment of specifications in chapter assignment. Inclusion of chapter texts from the previous BQF for DBL 9666-3. A before-and-after comparison is therefore not possible. NOTE: This translation is for information purposes only. The German version shall prevail above all others.

The inputs and outputs of control and field components shall be designed to resist short circuiting. Functional groups of a machine shall also be grouped together for address allocation. Signals may only be applied to binary inputs from one control unit each (e.g. pushbutton, position switch). Logic functions shall be realized within the control system. 20.2.2 Diagnostic messages All diagnostic messages provided by the bus subscribers shall be evaluated, displayed and forwarded to the MBE/BDE system 20.2.3 Measuring systems for linear and rotary axes Compressed air shall be applied via an independent filter combination to protect the measuring systems from coolant and lubricant mist. Data shall not be stored by the machine manufacturer in the internal memories of the position measuring systems. Such systems shall be exchangeable at any time with a standard measuring system of the measuring system manufacturer. In order to be able to quickly reset the NC axis following the replacement of the measuring system, the following specifications shall be observed: • An easily visible vernier (reference scale) shall be attached to the axis. • The reference dimension for input shall also be attached clearly visible next to the vernier (alternatively in the switch cabinet including a reference to the axis). • A drawing indicating the position of the vernier and the related reference dimension including machine data shall be enclosed with the documentation. • Measuring systems and sensor heads shall be exchangeable by using an installation aid such as dead stops (block dimension against ground surfaces), without the need for alignment with dial indicators. • Linear measuring systems shall be attached so that the sealing lips point towards the side not affected by splash water. If required, an additional mechanical cover shall be provided.

All programmable/configurable devices/assemblies shall also be incorporated and listed. The software version specified in the projects shall be employed. If no specifications have been defined, the version shall be adapted accordingly should several control systems be in use. The hardware and software required to program/parameterize the equipment/assemblies used shall form part of the delivery scope of the machine. The source code shall also be supplied for all programs written for the machine. A "Comments/description" line shall be created for each line of program code. 21.2 Password protection If a system offers a password protection function, this function shall be used. The password shall be coordinated during the course of the project and be communicated to the responsible parties. 22 Energy efficiency measures DIN EN ISO 50001 shall be taken into account in addition to the following requirements. 22.1 Sleep mode Sleep mode shall be defined as the scheduled switching off of the machine in the event of prolonged standstill (not in use). Sleep mode shall form part of the energy saving concept. Sleep mode shall be activated using an (adjustable) time control and using sensors/controls (e.g. no workpiece on the infeed/outfeed conveyor) or using an external signal. The machines shall be switched off in the required sequence taking into account any (adjustable) run-down times at the end of a cycle. Design specifications: A switch-off triggered by an external signal shall only be completed after a configurable run-down time, default setting 2 minutes. The active external signal shall be shown on the control panel. Transport, buffer, loading conveyors shall be switched off after expiry of a period with no loading or unloading, including a configurable run-down time. In the event of machine and material flow defects, the cooling lubricant shall be switched off in principle. If the machine requires a warm-up phase, a suitable concept shall be devised and coordinated. Sleep mode shall be displayed on the main control panel and reported to the MBE/BDE system Copyright Daimler AG MBN 9666-3 2020-07, page 60 22.2 Heat/cooling supply If electrical heating/cooling is required, the associated connection and connection conditions shall be coordinated. The control concept shall be implemented in line with heating/cooling requirements. 23 Engineered safeguards The following chapters and standards shall be observed with respect to emergency operations: • 9.2.3.4 Emergency operations (emergency stop, emergency off) • Aspects of the emergency stop device are referenced in the DIN EN ISO 13850 publication • Aspects of the emergency off device are covered in the IEC 60364-5-53:2001, 536.4 publication • 10.7 Emergency stop devices • 10.8 Emergency off devices The connecting cables in the field shall be selected in accordance with Table 5. If an analysis device is required to convert the sensor signal, the device shall come from the same manufacturer. Suspension apparatuses shall be provided for temporarily inactive mobile control panels that cover the emergency stop/emergency off button. All safety-relevant scopes shall be documented in a shutdown matrix. This matrix shall be checked prior to acceptance, and the result shall be documented and submitted for each item (the test result shall be handed over together with the overall documentation). A distinction is not made between emergency stop and emergency off devices. The mandatory response of the machine/submachine shall be provided by the manufacturer in line with the respective hazards 24 Component approval list See the project documentation for material approvals.
