2009年修订(9页)
A.目的
本章节描述的高速公路-铁路平交道口信号,反射器类型白炽光度单位的排列推荐规程负荷手册第3.2.35部分 (高速公路-铁路平交道口信号,反射器类型白炽光度单位的排列推荐设计)。该部分内容描述了操作规程建议的一般规定。
B.总则
除非高速公路和行人交通受到适当保护,不得开启本规定描述排列的反射器类型白炽光度单位。当排列装置时,必须小心确保没有不安全的情况存在。
1. 灯座由制造商安置并且进行密封。灯具符合手册第14.2.1部分规定(白炽电灯推荐设计标准和功能/运行指南),附录A,表1。为了取得预期的范围和效率,光度单位可采用精确信号灯。
2.当光度单位完成排列后,立即进行测试确定设备功能是否正常。
C.排列
光度单位排列方法参见表格335-1,335-2,335-3,335-4和335-5。限制临近交通速度的当地状况,或车辆司机临近交叉道口看到的信号的排列可以有所不同,但最大值为1,000英尺;操作程序如下:
1. 前灯单位
a.连续闪亮一个灯光装置。
b.把拦路木打开然后清楚地显示光线。
AREMA® C&S手册
3.3.5部分 2009
c.垂直调整光度单位,距离光线轴位置5英尺6英寸,选择距离路面高度。两个灯具应在同一条直线上。
d.水平调整光度单位,光线轴对准引路路线的中心位置,保持纵向的校准位置,两个灯具应在同一条直线上。
e.夹紧夹具并关闭门。
f.重覆指示C.1.a到C.1.e,包括在其它前灯单位。
2.后灯单位,使用的位置
a.连续闪亮一个灯光装置。
b.把拦路木打开然后清楚地显示光线。
c. 垂直调整光度单位,距离光线轴位置5英尺6英寸,距离轨道信号对面引路和引路行车道人行道50英尺。(如果存在多车道)。两个灯具应在同一条直线上。
d. 水平调整光度单位,距离轨道信号对面引路和引路行车道人行道50英尺。(如果存在多车道)。按照指示C.2.c对垂直对准线进行维护。
e. 夹紧夹具并关闭门。
f. 重覆指示C.1.a到C.1.e,包括在其它后灯单位。
3.在单位排列后,夹紧夹具并关闭门,检查装置闪动在正常工作电压的操作;确定闪光灯在1,000英尺之内的范围可见。
D. 圆形饰物
圆形饰物的典型安排如表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,灯具圆形饰物可以转动5度到10度顺时针。。

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.

AREMA® C&S Manual
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.
