仪表盘电气模块通用信息INSTRUMENT PANEL ELECTRICAL MODULE GENERAL INFORMATION
1. INTRODUCTION 介绍
A. The airplane instrument panel contains electrical modules which have a baseplate assembly, indicating lights, control switches, power connectors (light bases), and a wire bundle assembly. Some modules also include printed circuit card assemblies. The baseplate assembly has quick release fasteners which let you remove the module as a unit from the instrument panel. The baseplate and clamps can hold many different types of indicating instruments.
飞机仪表板包含电气模块，其中有底板组件、指示灯、控制开关、电源连接器（灯座）和电线束组件。某些模块还包括印刷电路板组件。底板组件带有快速释放紧固件，可将模块作为一个整体从仪表板上拆下。底板和夹具可容纳多种不同类型的指示仪表。

3. GENERAL 通用
A. Disassemble these modules only as necessary to clean, examine or repair the components.
只有在清洁、检查或修理元件时才可拆卸这些模块。
B. If you disassemble the module, see Figure 1 for details about the installation of module components.
如果拆卸模块，请参见图 1 了解模块组件安装的详细信息。
C. If some screws that attach standoffs are not easy to remove, they possibly were installed with Loctite compounds. When you install these screws, be sure to install them with Loctite compound unless a washer is also included (Figure 2).
如果某些连接支座的螺钉不易卸下，则可能是用乐泰化合物安装的。安装这些螺钉时，除非还包括垫圈，否则务必使用 Loctite 化合物进行安装（图 2）。
D. Refer to these standard practices, as applicable:
请参考以下适用的标准施工规范：
(1) SOPM 20-11-02 for electrical connectors
SOPM 20-11-02，电气连接器
(2) SOPM 20-11-03 for terminal lugs and electrical bond areas, and replacement of heat shrinkable tubing.
SOPM 20-11-03，端子接线片和电气接合区，以及更换热缩管。
(3) SOPM 20-12-01 for soldering
SOPM 20-12-01，焊接
(4) SOPM 20-12-02 for electrostatic-discharge-sensitive devices
SOPM 20-12-02，静电放电敏感设备
(5) SOPM 20-50-05 for application of aluminum foil and other markers

(6) SOPM 20-50-10 for application of stencils, part numbers and other identification markings
SOPM 20-50-10，模板、件号和其他识别标记的应用。
E. When you replace damaged wires, use the same wire type and color as the original, or as shown by the schematic diagram or applicable overhaul instructions.
更换损坏的导线时，应使用与原导线相同的导线类型和颜色，或按照原理图或适用的大修说明进行更换。
F. When you tie or replace ties on wiring harnesses, use the same type and color as the original, or as shown by the schematic diagram or applicable overhaul instructions. The color of the ties is important because it identifies the wire bundle by separation category, to keep wire bundles of one system apart from those of a different system. Table 2 shows typical Functional Separation Codes which are noted on schematic diagrams, along with the necessary wire tie color. Wires of different codes must have a minimum of 1/4-inch separation. Wires of different subcategory codes must also have a different routing. Thus category L2A wires must have a different routing than category L2B wires, although the two wires have the same red wire ties. Wires with N (neutral) codes can have the same routing as any other coded group unless the subcategories are different. Sleeving can be used to keep the wire bundles at the necessary separation.
绑扎或更换线束上的扎带时，应使用与原装相同的类型和颜色，或按照原理图或适用的大修说明书所示的类型和颜色。扎带的颜色非常重要，因为它可以按分类识别线束，从而将一个系统的线束与不同系统的线束区分开来。表 2 列出了原理图上标注的典型功能分类代码，以及必要的扎线带颜色。不同代码的导线必须至少有 1/4 英寸的间隔。不同子类别代码的导线也必须有不同的走线方式。因此，L2A 类导线的走线必须与 L2B 类导线的走线不同，尽管这两种导线使用相同的红色扎线带。具有 N（中性）代码的导线可以采用与任何其他代码组相同的布线方式，除非子类别不同。可使用套管将线束保持必要的间距。
G. Remove dust, dirt, and other unwanted material from the unit with low-pressure air suction.
用低压空气吸尘器清除设备上的灰尘、污垢和其他不需要的物质。
WARNING :WHEN YOU USE ISOPROPYL ALCOHOL OR ALIPHATIC NAPHTHA, TRY NOT TO BREATHE THE VAPORS TOO MUCH. USE THESE CLEANERS ONLY WITH A GOOD FLOW OF AIR. DO NOT GET THESE CLEANERS IN THE EYES, ON THE SKIN OR CLOTHING. KEEP THESE CLEANERS AWAY FROM HEAT, SPARKS, OR OPEN FLAME.

(5) Install a replacement light bulb. Many lightplates have printed data on them which can help identify replacement light bulbs and other parts. Most lightplates use 5-volt, 0.06-amp unbased lamps, such as part number 50001 available from Avio Corp. (V9U239) or Wamco (V58774). Solder the leads and cut off the unwanted lead lengths.
安装一个替换灯泡。许多灯盘上都印有数据，有助于识别替换灯泡和其他零件。大多数灯盘使用 5 伏、0.06 安培的无基座灯，如 Avio Corp. (V9U239) 或 Wamco (V58774) 提供的件号 50001。焊接引线并剪掉不需要的引线长度。
(6) Put the circuit board on the lightplate. Make sure there is clearance between the replacement light bulb and the lightplate. Unsolder and adjust the location of the replacement light bulb as necessary.
将电路板放在灯盘上。确保替换灯泡与灯板之间有间隙。必要时拆焊并调整替换灯泡的位置。
