修理工作的安全说明
ABB流量计的设计便于维修，这得益于统一更换零件和简单更换预定义零件。
但是，如果维修工作没有按照指南，这可能导致设备故障，对人员造成严重伤害，对环境造成危害。
对于安全关键设备和经认证可在爆炸危险环境中使用。
如果未进行维修，认证也将失效使用适当的工具或由未经适当培训的人员操作。
因此，我们建议流量计的所有维修工作由ABB服务技术人员执行。
作为设备制造商，ABB不能保证如果工作和/或ABB没有进行零件交换。
工厂操作员负责由客户、工厂运营商或第三方。在这种情况下，ABB将拒绝对任何不正确的设备功能负责特别是所有安全相关功能。
ABB不对设备性能、故障或损坏上述修理工作或更换。
所有缺陷责任应如果更换或修理工作不是由ABB。
如果您不确定维修流程，即使是部分或全部有替换零件，开始工作前的服务。进行维修时，遵守国家和国内法律。在里面有关爆炸中使用的认证流量计的特殊法律危险环境。在没有遵守法律要求可能导致撤销您的经营许可证。电阻制动交流驱动器的减速时间可以通过使用电阻制动。为此，必须配备变频器带有制动斩波器和制动电阻。
标准制动斩波器和制动电阻可用于ACS 600装置如表2-1所示。
斩波器和电阻器的额定功率等于ACS 600的短期过载能力可以在制动。额定正常使用的短期过载能力ACS 600是额定输出功率（电流）的110%，对于重型使用额定ACS 600，额定输出功率的150%（当前）。
制动斩波器NBRA-6xx公司
NBRA-6xx制动斩波器是ACS 600的可选设备家用变频器。
斩波器将制动电阻连接到变频器的中间电压电路超出最大限制。
Safety instructions for repair work
ABB flowmeters are designed to be easy to repair thanks to uniform replacement parts and simple replacement of predefined parts. However, if repair work is not carried out in accordance with the guidelines, this may result in malfunctioning of the device, causing serious injury to persons, and harm to the environment. This is especially true for safety-critical devices and those certified for use in explosion hazard environments. Certifications will also lapse if the repairs were not carried out with the proper tool or by persons without adequate training. We therefore recommend all repair work on flowmeters be carried out by ABB service technicians. As the manufacturer of the device, ABB cannot guarantee the necessary quality of the repair procedures if the work and/or parts exchange was not carried out by ABB. The plant operator is responsible for all repairs carried out by the customer, plant operator, or third party. In this case, ABB will reject all responsibility for any improper device functionality, in particular all safety-related functions.
ABB does not assume any liability for the deterioration or loss of device performance, malfunctions, or damage arising from the above repair work or replacement. All liability for defects shall lapse when the replacement or repair work is not carried out by ABB. If you are unsure about the repair process even if some or all replacement parts are available, please get in touch with ABB Service before beginning work. Respect national and internal laws when carrying out repairs. In particular laws relating to certified flowmeters used in explosion hazard environments. Repair work which is carried out without following the legal requirements can result in the revocation of your operating permit.
Resistor Braking
The deceleration time of an AC drive can be decreased by using resistor braking. For this, the frequency converter has to be equipped with a braking chopper and a braking resistor. The standard braking choppers and braking resistors available for the ACS 600 units are given in Table 2-1. The choppers and the resistors are rated so that the power equal to the short-term overload capacity of the ACS 600 can be handled during braking. The short-term overload capacity for a Normal Use rated ACS 600 is 110 % of the rated output power (current), and, for a Heavy-duty Use rated ACS 600, 150 % of the rated output power (current). Braking Chopper NBRA-6xx The NBRA-6xx Braking Choppers are optional devices for ACS 600 Family frequency converters. The chopper connects the braking resistor to the intermediate circuit of the frequency converter whenever the voltage in the intermediate circuit exceeds the maximum limit.
