Safety Instructions
Documentation
The latest versions of all eDAQXR and eDAQXR-lite documentation are available for download at www.hbm.com.
Appropriate use
The eDAQXR or eDAQXR-lite equipment and the connected transducers may be used for measurement and directly related control tasks only. Any other use is not appropriate.
To ensure safe operation, the equipment may only be used as specified in the operating manual. It is also essential to follow the respective legal and safety regulations for the application concerned during use. The same applies to the use of accessories.
Each time, before starting up the equipment, you must first run a project planning and risk analysis that takes into account all the safety aspects of automation technology. This particularly concerns personal and machine protection.
Additional safety precautions must be taken in plants where malfunctions could cause major damage, loss of data or even personal injury. In the event of a fault, these precautions establish safe operating conditions.
This can be done, for example, by mechanical interlocking, error signaling, limit value switches, and such.
Safety rules
The equipment must not be connected directly to a DC power supply network. The maximum permissible supply voltage is 36 VDC. The operating range is:
EXRCPU data processor | 8 VDC ... 36 VDC |
EXRLCPU data processor | 8 VDC ... 36 VDC |
EXRBRG conditioning layer | 8 VDC ... 36 VDC |
The supply connection, as well as the signal and sense leads, must be installed in such a way that electromagnetic interference does not adversely affect device functionality. (HBM recommendation: "Greenline shielding design," downloadable from the Internet at www.hbm.com.)
Automation equipment and devices must be covered over in such a way that adequate protection or locking against unintentional actuation is provided (such as access checks, password protection, etc.).
When devices are working in a network, these networks must be designed in such a way that malfunctions in individual nodes can be detected and shut down.
Safety precautions must be taken both in terms of hardware and software, so that a line break or other interruptions to signal transmission, such as via the bus interfaces, do not cause undefined states or loss of data in the automation device.
Conditions on site
For all equipment:
- Observe the maximum permissible ambient temperatures given in the specifications.
- Minimize device exposure to direct sunlight in hot operating environments.
Maintenance and cleaning
The equipment is maintenance-free. Please note the following when cleaning the housing:
- Before cleaning, disconnect the equipment completely.
- Clean the housing with a soft, slightly damp (not wet) cloth. Never use solvents, since these could damage the labeling on the front panel and the display.
- Do not apply high water pressure to the unit for cleaning.
General dangers of failing to follow the safety instructions
The equipment is a state of the art device and, as such, is fail-safe. The equipment may give rise to further dangers if it is inappropriately installed and operated by untrained personnel. Any person instructed to carry out installation, commissioning, maintenance or repair of the equipment must have read and understood the User Manuals and in particular the technical safety instructions.
Remaining dangers
The scope of supply and performance of the equipment covers only a small area of measurement technology. In addition, equipment planners, installers and operators should plan, implement and respond to the safety engineering considerations of measurement technology in such a way as to minimize remaining dangers. Prevailing regulations must be complied with at all times. There must be reference to the remaining dangers connected with measurement technology. After making settings and carrying out activities that are password-protected, you must make sure that any controls that may be connected remain in safe condition until the switching performance of the equipment has been tested.
Product liability
In the following cases, the protection provided for the device may be adversely affected. Liability for device functionality then passes to the operator:
- The device is not used in accordance with the operating manual.
- The device is used outside the field of application described in this chapter.
- The operator makes unauthorized changes to the device.
Working safely
Error messages should only be acknowledged once the cause of the error is removed and no further danger exists.
The equipment complies with the EMC standards of EN 61326‑1 / EN 61326‑2‑x. These standards define emission limits and immunity requirements for multiple environments.
With respect to emissions, the standards contain limits for industrial (class A) and Domestic and Industrial (class B) environments. The standard herein references CISPR 11:2009+A1:2010.
With respect to immunity, the standards contain limits for electromagnetic protected (lowest requirements), general and industrial (highest requirements) environments.
The eDAQXR or eDAQXR-lite devices listed in the declaration of conformity adhere to the requirements for:
- Emissions: Class A
- Immunity: Industrial
The eDAQXR or eDAQXR-lite series and its modules are intended for use in an industrial environment. When used in residential or commercial environments, additional arrangements may be required to limit electromagnetic emissions.
Conversions and modifications
The equipment must not be modified from the design or safety engineering point of view except with our expressed agreement. Any modification shall exclude all liability on our part for any resultant damage.
In particular, any repair or soldering work on motherboards or replacement of components is prohibited. When exchanging complete modules, use only original parts from HBM.
The equipment is delivered from the factory with a fixed hardware and software configuration. Changes can only be made within the possibilities documented in the manuals.
Qualified personnel
Qualified persons means persons entrusted with the installation, fitting, commissioning and operation of the product who possess the appropriate qualifications for their function. This module is only to be installed and used by qualified personnel, strictly in accordance with the specifications and the safety rules and regulations.
This includes people who meet at least one of the three following requirements:
- Knowledge of the safety concepts of automation technology is a requirement and as project personnel, you must be familiar with these concepts.
- As automation plant operating personnel, you have been instructed how to handle the machinery and are familiar with the operation of the modules and technologies described in this documentation.
- As commissioning engineers or service engineers, you have successfully completed the training to qualify you to repair the automation systems. You are also authorized to activate, to ground and label circuits and equipment in accordance with safety engineering standards.
It is also essential to comply with the legal and safety requirements for the application concerned during use. The same applies to the use of accessories.
