WOODWARD 5466-258伺服調速器，5466-258使用說明
為了正確操作板載SRAM，需要一些跳線組合必須安裝在備用電源上選擇標題。如果其中一個跳線用于選擇電池，電池必須安裝在MVME162上。這個如果保留對DS1210的輸入，SRAM可能會出現故障未連接。SRAM由MCchip控制，訪問時間可編程。請參閱MVME162嵌入式控制器中的MCchip說明程序員參考指南了解更多詳細信息。關于電池機載SRAM的電源是一個RAYOVAC FB1225電池，帶有兩個BR1225型鋰電池，帶插座，便于拆卸和更換。
WOODWARD 5466-258伺服調速器A.提供小電容器，以便快速更換電池無數據丟失。電池的壽命在很大程度上取決于電池的環境溫度電路板和通電占空比。上提供的鋰電池MVME162應為電路板提供至少兩年的備份時間斷電，環境溫度為40°C。如果通電周期為50%（電路板一半時間通電），電池壽命為四年。在較低的環境溫度下，備份時間顯著縮短更長，可能接近電池的保質期。存儲電路板時，應斷開電池以延長電池壽命生活這在高環境溫度下尤為重要。MVME162在電池斷開的情況下裝運（即VMEbus+5V備用選擇電壓作為一次和二次電源）。如果你愿意的話要將電池用作電源，無論是主電源還是輔助電源，都需要在安裝模塊之前，需要重新配置J20上的跳線。參考對于SRAM備用電源，選擇第2章中的標題J20以獲取可用信息跳線配置。電池的電源線暴露在電路板的焊接側。電路板不應放置在導電表面或存儲在除非拆下電池，否則使用導電袋。鋰電池包含易燃材料，如鋰和有機溶劑。如果鋰電池受到不當處理或處理不當，它們可能會爆裂并點燃，可能導致受傷和/或火災。在處理鋰電池時，請仔細遵循列出的注意事項為了防止事故發生。? 不要短路。
? 不要拆卸、變形或施加過大壓力。? 不要加熱或焚燒。? 不要直接使用焊料。? 不要使用不同型號的電池，或將新舊電池混合在一起。? 不要充電。? 始終檢查正確的極性。要從模塊中卸下電池，請小心地從插座安裝新電池之前，請確保電池針腳清潔。注意電池極性，然后將電池壓入插座。當電池處于工作狀態時插座，無需焊接。
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.
