4.1.2 TA 951F battery for RAM buffering

为RAM缓存的TA 951F电池

The accessory TA 951F comprises a 2/3A lithium battery with connecting cable.The battery is provided with a plastic sheathing. This battery can be replaced while the AC 900F is in operation.

配件TA 951F是包含连接线的2/3A的锂电池。电磁（包装）由塑料保护套。该电池可以在AC 900F控制器工作时进行更换。

• Cylindrical lithium cell圆柱形锂电池
• Lithium metal 锂金属
• 3 V, 1200 mAh or 1450 mAh
• Primary cell, non-rechargeable 主单元，不可充电
• Mechanical plug coding to prevent reverse polarity 防误插机械插头（不用担心正负插反）

USE

用于

The TA 951F lithium battery serves to supply the real time clock and the SRAM in order to save the memory contents (e.g. process and configuration data) in the event of power failure.

TA 951F锂电池为实时时钟和SRAM供电，以便在断电时，保存内存内容（比如过程和配置数据）

The CPU module is delivered without lithium battery. A new TA 951F battery must always be inserted during initial start-up of the CPU module.

CPU 模块无需锂电池即可交付。新的 TA 951F 电池必须始终在 CPU 模块的初始启动过程中插入。

      After longer voltage supply interruptions at the CPU module (maintenance operations, shut-down, transport or similar), a new battery must be installed as well in order to ensure the specified buffering times.

     如果较长时间CPU模板的电源中断（维护、操作、关机、运输或者类似情况），必须安装新的电池以确保指定的缓存时间。

Although the CPU module can also be operated without battery its use is strictly recommended in order to avoid data loss.

虽然说CPU可以在没有电池的情况下操作，但是它的使用是严格的，建议为了避免数据丢失，还是得加电池。

     The CPU module monitors the battery voltage and thus indirectly also the battery capacity (charging status). The “Low CPU module battery capacity” message is issued when the capacity has reached a level that is sufficient for 14 days buffering. The battery should be replaced at regular intervals and as soon as possible after the low battery warning has been displayed。

CPU模块监视电池电压从而间接的监视电池容量。当电池容量仅能缓存14天时，会发出“CPU电池容量低”的消息。电池应定期更换，并在显示低电池警告后尽快更换。

      The TA 951F lithium battery is the only battery type that is compatible with the PM CPU module. It is a non-rechargeable primary cell。

      TA 951F锂电池是唯一的兼容PM CPU模板的电池型号，它是不可充电的单元。

The battery must only be replaced with the controller supply voltage ON in order to avoid any data loss. 电池只能在控制器电源为ON的时候更换，以避免数据丢失。   Data buffering is not possible without a battery when the supply voltage is switched off. 电源电压关闭时，没有电池就不可能数据缓存。

Safety instructions

安全介绍

Risk of overheating and subsequent explosion!

过热和随后的爆炸风险

Batteries must not be short-circuited, recharged, opened or thrown into  fire! 电池不能短接、充电、打开和扔进火里！   Store the batteries in a dry place. 干燥环境保存电池   Strictly observe the applicable local recycling and environmental regulations during disposal of used batteries. 严格遵守适用的当地回收和环境废旧电池处置过程中的规定。 Lithium metal batteries are subject to the provision of the Air Transport Association (IATA). 锂电池受制于国际航空运输协会的相关条款。

Battery lifetime

电池寿命

      The battery lifetime is the time the battery will retain data while the power supply to the CPU module is switched off. As long as the CPU module is powered, the battery will be discharged by a very low test current and its self-discharge。

      电池寿命指的是当CPU断电时，电池能够保存数据的时间。只要CPU模板有电，电池将通过非常低的测试电流和自卸释放。
