WOODWARD 5466-258伺服调速器，5466-258使用说明

为了正确操作板载SRAM，需要一些跳线组合必须安装在备用电源上选择标题。如果其中一个跳线用于选择电池，电池必须安装在MVME162上。这个如果保留对DS1210的输入，SRAM可能会出现故障未连接。SRAM由MCchip控制，访问时间可编程。请参阅MVME162嵌入式控制器中的MCchip说明程序员参考指南了解更多详细信息。关于电池机载SRAM的电源是一个RAYOVAC FB1225电池，带有两个BR1225型锂电池，带插座，便于拆卸和更换。

WOODWARD 5466-258伺服调速器A.提供小电容器，以便快速更换电池无数据丢失。电池的寿命在很大程度上取决于电池的环境温度电路板和通电占空比。上提供的锂电池MVME162应为电路板提供至少两年的备份时间断电，环境温度为40°C。如果通电周期为50%（电路板一半时间通电），电池寿命为四年。在较低的环境温度下，备份时间显著缩短更长，可能接近电池的保质期。存储电路板时，应断开电池以延长电池寿命生活这在高环境温度下尤为重要。MVME162在电池断开的情况下装运（即VMEbus+5V备用选择电压作为一次和二次电源）。如果你愿意的话要将电池用作电源，无论是主电源还是辅助电源，都需要在安装模块之前，需要重新配置J20上的跳线。参考对于SRAM备用电源，选择第2章中的标题J20以获取可用信息跳线配置。电池的电源线暴露在电路板的焊接侧。电路板不应放置在导电表面或存储在除非拆下电池，否则使用导电袋。锂电池包含易燃材料，如锂和有机溶剂。如果锂电池受到不当处理或处理不当，它们可能会爆裂并点燃，可能导致受伤和/或火灾。在处理锂电池时，请仔细遵循列出的注意事项为了防止事故发生。❏ 不要短路。

❏ 不要拆卸、变形或施加过大压力。❏ 不要加热或焚烧。❏ 不要直接使用焊料。❏ 不要使用不同型号的电池，或将新旧电池混合在一起。❏ 不要充电。❏ 始终检查正确的极性。要从模块中卸下电池，请小心地从插座安装新电池之前，请确保电池针脚清洁。注意电池极性，然后将电池压入插座。当电池处于工作状态时插座，无需焊接。

For proper operation of the onboard SRAM, some jumper

combination must be installed on the Backup Power Source

Select Header. If one of the jumpers is used to select the

battery, the battery must be installed on the MVME162. The

SRAM may malfunction if inputs to the DS1210S are left

unconnected.

The SRAM is controlled by the MCchip, and the access time is programmable.

Refer to the MCchip description in the MVME162 Embedded Controller

Programmer’s Reference Guide for more detail.

About the Battery

The power source for the onboard SRAM is a RAYOVAC FB1225 battery with

two BR1225 type lithium cells, socketed for easy removal and replacement. A

small capacitor is provided so that the batteries can be quickly replaced

without data loss.

The lifetime of the battery is very dependent on the ambient temperature of the

board and the power-on duty cycle. The lithium battery supplied on the

MVME162 should provide at least two years of backup time with the board

powered off and with an ambient temperature of 40° C. If the power-on duty

cycle is 50% (the board is powered on half of the time), the battery lifetime is

four years. At lower ambient temperatures the backup time is significantly

longer and may approach the shelf life of the battery.

When a board is stored, the battery should be disconnected to prolong battery

life. This is especially important at high ambient temperatures. The MVME162

is shipped with the battery disconnected (i.e., with VMEbus +5V standby

voltage selected as both primary and secondary power source). If you intend

to use the battery as a power source, whether primary or secondary, it is

necessary to reconfigure the jumpers on J20 before installing the module. Refer

to SRAM Backup Power Source Select Header J20 in Chapter 2 for available

jumper configurations.

The power leads from the battery are exposed on the solder side of the board.

The board should not be placed on a conductive surface or stored in a

conductive bag unless the battery is removed.Lithium batteries incorporate flammable materials such as

lithium and organic solvents. If lithium batteries are mistreated or handled incorrectly, they may burst open and

ignite, possible resulting in injury and/or fire.

When dealing with lithium batteries, carefully follow the precautions listed

below in order to prevent accidents.

❏ Do not short-circuit.

❏ Do not disassemble, deform, or apply excessive pressure.

❏ Do not heat or incinerate.

❏ Do not apply solder directly.

❏ Do not use different models, or mix new and old batteries together.

❏ Do not charge.

❏ Always check proper polarity.

To remove the battery from the module, carefully pull the battery from the

socket.

Before installing a new battery, ensure that the battery pins are clean. Note the

battery polarity and press the battery into the socket. When the battery is in

the socket, no soldering is required.
