6.励磁设备的释放值由指定增长励磁而定，直到获得正常运行数值，然后逐渐减少励磁数值，直到励磁设备释放。
7. 拦路木扭矩的调整必须符合制造商的要求做或相关要求。
8. 拦路木运行一致、顺利并且在完成所有运动没有反弹或断裂；在上升的位置安全稳定。
9. 制造商拦路木缓冲或突然制止机制必须有效，并符合制造商的要求做或相关要求。
10.当使用计量器时，正确进行调整。
11.拦路木机制电路控制器进过适当调整和对准。
E.铃铛
检查和测试确保：

2.按照要求，铃铛运行在每分钟冲程/推力在100-325种之间。
Recommended Instructions for Inspection and Test of Highway-Rail Grade Crossing Warning System Installation Before Placing in Service
Revised 2006 (3 Pages)
A. Purpose
This Manual Part recommends instructions that apply to the inspection and testing of highway-rail grade crossing warning devices and system installations or modifications before placing in service. They set forth general requirements representing recommended practices.
B. General
Check and test to ensure that:
1. Plans are legible and correct, and kept at all locations.
2. Stand-by source(s) of power is provided as designed and functions as
intended.
3. For each highway approach, signals are properly aligned and view of
signals is not obstructed.
4. Voltage at each light unit is as instructed.
5. Where manual cut-out and starting buttons are used, they function for
each track as intended.
6. Time of time element relays or any solid state device which performs the
same function, where used in starting circuits, is not less than time shown
on approved plans.
7. Warning devices function as intended.
8. Control systems, including highway traffic signal pre-emption
interconnection, if applicable, function as intended.
9. On primary batteries after continuous load for 5 minutes, or after a shunt
of 0.5 ohm has been applied for 5 minutes, voltage measures normal.
10. Proper signs are installed, clean and clearly visible to approaching traffic
on highway.

11. Each circuit that affects the proper functioning of a highway-rail grade
crossing warning system is free of any ground or combination of grounds,
as instructed.
12. All wires and cables installed are tested for insulation resistance, as
instructed.
13. Results of inspections and tests are recorded as instructed.
C. Flashing light units:
Check and test to ensure that:
1. Light units are mounted horizontally on 2 ft. 6 in. centers and not less than
7 ft. 6 in. to the bottom of background above the crown of the roadway.
2. Light units flash alternately and the number of flashes of each light unit per
minute is 35 minimum, 65 maximum.
3. Light units are illuminated approximately the same length of time. Total
time of illumination of each pair of light units shall be the entire operating
time.
4. Light units are properly aligned, conforming to Manual Part 3.3.5
(Recommended Instructions for Aligning Highway-Rail Grade Crossing
Signal, Reflector-Type Light Units), or as instructed.
D. Automatic gates:
Check and test to ensure that:
1. Each gate arm is equipped with not less than three red light units, visible
to approaching highway users.
2. The gate arm, when in raised position, does not obstruct or interfere with
highway traffic.
3. Gate arms start their downward motion as designed but not less than 3
seconds after flashing light units start to operate.
4. Gate arms assume the horizontal position at least 5 seconds before the
arrival of any normal train movement through the crossing.
5. Gate arms fully rise in not more than 12 sec., or as instructed.

6. Release values of hold clear excitation devices are as specified by
increasing excitation until normal operating value is obtained, then
reducing excitation gradually until hold clear device releases.
7. Gate arm torque adjustments are made per manufacturer's instructions, or
as instructed.
8. Gate arms operate uniformly, smoothly, and complete all movements
without rebound or slap, and are securely held when in the raised position.
9. Buffing or snubbing of gate mechanism is effective, per manufacturer's
