IC693ACC302A 标准内存备份电池

【产品详情】

与系列90-30、系列90-70和PACSystems cpu的标准内存备份电池相比，IC693ACC302辅助电池可提供更长的内存备份时间。辅助电池模块取代了控制系统中的标准CPU RAM备用电池。

当使用这个辅助电池组时，这些设备的RAM内存备份时间可以延长到75个月。CPU374是唯一的例外，它可以延长到15个月。

操作记录

本设备不应由用户维修。如果需要维护或测试，应由受过培训的具有电气安全实践能力的专业人员进行。PDF电力供应公司提供维修服务。有一个1安培保险丝密封在电池组内。这种保险丝在短路或严重过载的情况下会断开。如果您认为保险丝已断开，则需要对该装置进行如下测试:

关闭PLC电源。

拔掉电池插头。

使用电压表检查电池电缆上的连接器插脚是否有电压。

如果有电源，保险丝没有打开。如果没有电压，保险丝很可能是断开的。在这种情况下，设备需要更换。

日期代码

在辅助电池模块的正面，你可以找到日期代码。它由三位数组成。第一个数字是制造年份，而最后两个数字是制造的财政周。

例如，日期代码315表示电池是在2003年的第15个财政周制造的。

这些单元的保质期相对较短，大约为7年。出于这个原因，任何已经在存储很长时间的电池组都应该处理掉。

安全处理

在其使用寿命结束时，确保所有电池组被安全处置。请遵循产品附带的材料安全数据表(MSDS)中的指导方针

【英文介绍】

The IC693ACC302 auxiliary battery provides longer memory backup times than the standard memory backup battery for Series 90-30, Series 90-70, and PACSystems cpus. The auxiliary battery module replaces the standard CPU RAM backup battery in the control system.

When using this auxiliary battery pack, the RAM memory backup time of these devices can be extended to 75 months. The CPU374 is the only exception, which can be extended up to 15 months.

Operation record

This equipment should not be repaired by the user. If maintenance or testing is required, it should be carried out by trained professionals who are competent in electrical safety practices. PDF Electric Supply Company provides maintenance service. There is a 1 amp fuse sealed inside the battery pack. This fuse will break in case of short circuit or severe overload. If you think the fuse is disconnected, you need to test the device as follows:

Power off the PLC.

Unplug the battery.

Use a voltmeter to check the connector pin on the battery cable for voltage.

If there is power, the fuse is not open. If there is no voltage, the fuse is likely to be disconnected. In this case, the equipment needs to be replaced.

Date code

On the front of the auxiliary battery module, you can find the date code. It consists of three digits. The first number is the year of manufacture, while the last two numbers are the fiscal week of manufacture.

For example, the date code 315 indicates that the battery was manufactured in the 15th fiscal week of 2003.

These units have a relatively short shelf life of about seven years. For this reason, any battery packs that have been in storage for a long time should be disposed of.

Safe handling

Ensure that all battery packs are disposed of safely at the end of their service life. Follow the guidelines in the Material Safety Data Sheet (MSDS) that comes with the product
