反射器排列推薦規程-中英對照
高速公路-鐵路平交道口信號，反射器類型白熾光度單位的排列推薦規程
2009年修訂(9頁)
A.目的
本章節描述的高速公路-鐵路平交道口信號，反射器類型白熾光度單位的排列推薦規程負荷手冊第3.2.35部分 (高速公路-鐵路平交道口信號，反射器類型白熾光度單位的排列推薦設計)。該部分內容描述了操作規程建議的一般規定。
B.總則
除非高速公路和行人交通受到適當保護，不得開啟本規定描述排列的反射器類型白熾光度單位。當排列裝置時，必須小心確保沒有不安全的情況存在。
1. 燈座由制造商安置并且進行密封。燈具符合手冊第14.2.1部分規定(白熾電燈推薦設計標準和功能/運行指南)，附錄A，表1。為了取得預期的范圍和效率，光度單位可采用精確信號燈。
2.當光度單位完成排列后，立即進行測試確定設備功能是否正常。
C.排列
光度單位排列方法參見表格335-1，335-2，335-3，335-4和335-5。限制臨近交通速度的當地狀況，或車輛司機臨近交叉道口看到的信號的排列可以有所不同，但最大值為1,000英尺；操作程序如下：
1. 前燈單位
a.連續閃亮一個燈光裝置。
b.把攔路木打開然后清楚地顯示光線。
AREMA® C&S手冊
3.3.5部分 2009
c.垂直調整光度單位，距離光線軸位置5英尺6英寸，選擇距離路面高度。兩個燈具應在同一條直線上。
d.水平調整光度單位，光線軸對準引路路線的中心位置，保持縱向的校準位置，兩個燈具應在同一條直線上。
e.夾緊夾具并關閉門。
f.重覆指示C.1.a到C.1.e，包括在其它前燈單位。
2.后燈單位，使用的位置
a.連續閃亮一個燈光裝置。
b.把攔路木打開然后清楚地顯示光線。
c. 垂直調整光度單位，距離光線軸位置5英尺6英寸，距離軌道信號對面引路和引路行車道人行道50英尺。(如果存在多車道)。兩個燈具應在同一條直線上。
d. 水平調整光度單位，距離軌道信號對面引路和引路行車道人行道50英尺。(如果存在多車道)。按照指示C.2.c對垂直對準線進行維護。
e. 夾緊夾具并關閉門。
f. 重覆指示C.1.a到C.1.e，包括在其它后燈單位。
3.在單位排列后，夾緊夾具并關閉門，檢查裝置閃動在正常工作電壓的操作；確定閃光燈在1,000英尺之內的范圍可見。
D. 圓形飾物
圓形飾物的典型安排如表335-6和335-7所示。在交叉道口引路突然上升的位置，在完成部分C操作以后后，燈具圓形飾物可以轉動5度到10度順時針。。

ecommended Instructions for Aligning Highway-Rail Grade Crossing Signal, Reflector-Type Incandescent Light Units
Revised 2009 (9 Pages)
A. Purpose
This Manual Part recommends instructions for aligning highway-rail grade crossing signal reflector-type incandescent light units that conform to Manual Part 3.2.35 (Recommended Design Criteria for Electric Light Unit for Highway-Rail Grade Crossing Signals Including Light Emitting Arrays and Incandescent Lamps). They set forth general requirements representing recommended practice.
B. General
The aligning of reflector-type incandescent light units conforming to these instructions shall not be started until proper protection has been afforded for highway and pedestrian traffic. When aligning, care shall be exercised that no unsafe conditions are created.
1. The lamp receptacles are positioned and sealed by the manufacturer.
Lamps shall conform to Manual Part 14.2.1 (Recommended Design
Criteria and Functional/Operating Guidelines for Incandescent Electric
Lamps), Appendix A, Table 1. To obtain the range and efficiency intended,
signal precision lamps shall be used in the light units.
2. When aligning of light units has been completed, tests shall be made
immediately to determine that the equipment functions as intended.
C. Alignment
A method of aligning light units is illustrated in Figures 335-1, 335-2, 335-3, 335-4 and 335-5. Local conditions which limit speed of approaching traffic, or distance at which the signals can be seen by drivers of vehicles approaching the crossing will vary the point of alignment up to a maximum of 1,000 ft. Procedure is as follows:
1. Front light units
a. Continuously light one lamp.
b. Open door wide so clear beam is displayed.

Part 3.3.5 2009
c. Adjust light unit vertically to align axis of beam 5 ft. 6 in. above
pavement at selected alignment distance. Both lamps should be
aligned to same point.
d. Adjust light unit horizontally to align axis of beam to center of
approach lane in approach to signal at selected alignment distance,
maintaining vertical alignment. Both lamps should be aligned to
same point.
e. Tighten clamps and close door.
f. Repeat instructions C.1.a to C.1.e, inclusive, on other front light
units.
2. Back light units, where used
a. Continuously light one lamp.
b. Open door wide so clear beam is displayed.
c. Adjust light unit vertically to align axis of beam 5 ft. 6 in. above
pavement at a point 50 ft. in approach to the signal on opposite
side of track and in center of approach travel way (this is if multiple
lanes exist). Both lamps should be aligned to same point.
d. Adjust light unit horizontally to align axis of beam to a point 50 ft. in
approach to the signal on opposite side of track and in center of
approach travel way (this is if multiple lanes exist), maintaining
vertical alignment as in Instruction C.2.c.
e. Tighten clamps and close door.
f. Repeat Instructions C.2.a to C.2.e, inclusive, on other back light
units.
3. After units have been aligned, clamps tightened and doors closed, they
must be checked with lights flashing at normal operating voltage to make
certain a flashing light aspect is visible within a range of 1,000 ft.
D. Roundels
Typical arrangements of roundels are shown in Figures 335-6 and 335-7. Where the approach to the crossing rises abruptly, back light roundels may be rotated 5 deg. to 10 deg. clockwise, after completion of Section C.
