修理工作的安全說(shuō)明
ABB流量計的設計便于維修，這得益于統一更換零件和簡(jiǎn)單更換預定義零件。
但是，如果維修工作沒(méi)有按照指南，這可能導致設備故障，對人員造成嚴重傷害，對環(huán)境造成危害。
對于安全關(guān)鍵設備和經(jīng)認證可在爆炸危險環(huán)境中使用。
如果未進(jìn)行維修，認證也將失效使用適當的工具或由未經(jīng)適當培訓的人員操作。
因此，我們建議流量計的所有維修工作由ABB服務(wù)技術(shù)人員執行。
作為設備制造商，ABB不能保證如果工作和/或ABB沒(méi)有進(jìn)行零件交換。
工廠(chǎng)操作員負責由客戶(hù)、工廠(chǎng)運營(yíng)商或第三方。在這種情況下，ABB將拒絕對任何不正確的設備功能負責特別是所有安全相關(guān)功能。
ABB不對設備性能、故障或損壞上述修理工作或更換。
所有缺陷責任應如果更換或修理工作不是由ABB。
如果您不確定維修流程，即使是部分或全部有替換零件，開(kāi)始工作前的服務(wù)。進(jìn)行維修時(shí)，遵守國家和國內法律。在里面有關(guān)爆炸中使用的認證流量計的特殊法律危險環(huán)境。在沒(méi)有遵守法律要求可能導致撤銷(xiāo)您的經(jīng)營(yíng)許可證。電阻制動(dòng)交流驅動(dòng)器的減速時(shí)間可以通過(guò)使用電阻制動(dòng)。為此，必須配備變頻器帶有制動(dòng)斬波器和制動(dòng)電阻。
標準制動(dòng)斬波器和制動(dòng)電阻可用于A(yíng)CS 600裝置如表2-1所示。
斬波器和電阻器的額定功率等于A(yíng)CS 600的短期過(guò)載能力可以在制動(dòng)。額定正常使用的短期過(guò)載能力ACS 600是額定輸出功率（電流）的110%，對于重型使用額定ACS 600，額定輸出功率的150%（當前）。
制動(dòng)斬波器NBRA-6xx公司
NBRA-6xx制動(dòng)斬波器是ACS 600的可選設備家用變頻器。
斬波器將制動(dòng)電阻連接到變頻器的中間電壓電路超出最大限制。
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.
