122AA-00010AB-S Knowledge of regulations and the proper technical implementation of the safety instructions detailed in this manual performed by qualified personnel are prerequisites for safely planning, engineering, programming, installing and starting up the HIMax automation devices, as well as for ensuring safety during their operation and maintenance. HIMA will not be held liable for severe personal injuries, damage to property or the surroundings caused by any of the following: unqualified personnel working on or with the devices, de-activation or bypassing of safety functions, or failure to comply with the instructions detailed in this manual (resulting in faults or impaired safety functionality). HIMax automation devices have been developed, manufactured and tested in compliance with the pertinent safety standards and regulations. They must only be used for the intended applications under the specified environmental conditions. 1.1 Validity and Current Version Version Rev. 4.00 This revision must be used with version 4 and higher of the HIMax system. The most current version of the Safety Manual, indicated by the highest version number, is applicable and valid. The current version is available on the current HIMA DVD or can be downloaded from the HIMA website at www.hima.com. 1.2 Objectives of the Manual This manual contains information on how to operate the HIMax safety-related automation device in the intended manner. It provides an introduction to the safety concept of the HIMax system and should increase the reader's safety awareness. The Safety Manual is based upon the contents of the certificate and of the test report for the certificate. 1.3 Target Audience This manual addresses system planners, configuration engineers, programmers of automation devices and personnel authorized to start up, operate and maintain the devices and systems. Specialized knowledge of safety-related automation systems is required. 1.4 Formatting Conventions To ensure improved readability and comprehensibility, the following fonts are used in this document: Bold: To highlight important parts Names of buttons, menu functions and tabs that can be clicked and used in SILworX.

These notes must absolutely be observed to reduce the risk to a minimum. The content is structured as follows: Signal word: danger, warning, caution, notice Type and source of danger Consequences arising from the danger Danger prevention The signal words have the following meanings: Danger indicates hazardous situation which, if not avoided, will result in death or serious injury. Warning indicates hazardous situation which, if not avoided, could result in death or serious injury. Warning indicates hazardous situation which, if not avoided, could result in minor or modest injury. Notice indicates a hazardous situation which, if not avoided, could result in property damage. NOTICE Type and source of damage! Damage prevention 1.4.2 Operating Tips Additional information is structured as presented in the following example: i The text corresponding to the additional information is located here. Useful tips and tricks appear as follows: TIP The tip text is located here. SIGNAL WORD Type and source of danger!

All HIMax input and output modules (I/O modules) can be operated with an individual processor module or with several redundant processor modules. When implementing safety-related communications between various devices, ensure that the overall response time does not exceed the fault tolerance time. All calculations must be performed in accordance with the rules specified in Safety Manual HI 800 003 E. Only connect devices with safe electrical isolation to the communications interfaces. 2.1.1 Application in accordance with the 'De-Energize to Trip Principle' The automation devices have been designed in accordance with the 'de-energize to trip' principle. A system that operates in accordance with the 'de-energize to trip principle' does not require any power to perform its safety function. Thus, if a fault occurs, the input and output signals adopt a de-energized, safe state. 2.1.2 Application in accordance with the 'Energize to Trip Principle' The HIMax controllers can be used in applications that operate in accordance with the 'energize to trip' principle. A system operating in accordance with the 'energize to trip' principle requires power (such as electrical or pneumatic power) to perform its safety function. When designing the controller system, the requirements specified in the application standards must be taken into account. For instance, line diagnosis for the inputs and outputs may be required 2.1.3 Use in Fire Alarm Systems All HIMax systems with analog inputs are tested and certified for used in fire alarm systems in accordance with DIN EN 54-2 and NFPA 72. To contain the hazard, these systems must be able to adopt an active state on demand. The operating requirements must be observed! 2.2 Non-Intended Use The transfer of safety-relevant data through public networks like the Internet is not permitted unless additional security measures such as VPN tunnel or firewall have been implemented to increase security. With fieldbus interfaces, no safety-related communication can be ensured. The use under environmental conditions other than those specified in the following section is not permitted. |
