恒定报警定间装置典型电路-中英对照
维护和测试
1.如果适用，在敏感系统的任何再调整之前或按照铁路部门的指示要求，检查列车运行内部维护日志和报警时间，确认系统正操作。
2. 在任何系统发生变动的时候，程序的再调整和设定要求符合制造商和铁路部门指示，包括任何设备或模块、轨道电路或者接线。
3.如果轨道电路或设备的调整和设定有任何变化，按照制造商和铁路部门的要求，采用测试转辙器或观察列车移动，保证系统能完全运行轨道电路。
4.如果没有首先确定改变的必要性，设备不得对系统再调整校准水平超出3%。如果没有确定改变的必要性，可能会忽视断裂路轨、损坏的捆绑物和耦合装置或者发生故障的转辙器。
5.岛式电路再调整要求符合制造商和铁路的指示。
6. 除非制造商明确表示允许，在设备去除、更换或者替换模块之前，模块或适当设备必须断电。
7.在设备去除、更换或者替换模块之前，新模块任何站点规定的编程在是相同象原物模块。
8.不建议对场地设备模块进行修理或修改。修理作业要求符合手册第1.5.1部分(固体设备设施和维护推荐规程)，和制造商和铁路部门的指示。要求根据制造商的指示进行铁路部门认可的相关升级和改进。对随后的修理或修改进行测试，保证模块的所有功能正常。

Maintenance and Test
1. If available, prior to any readjustments to constant warning time devices or
as required by the railroad's instructions, internally maintained logs of train
moves and warning times shall be reviewed to confirm proper operation of
the system.
2. Readjustment and setup procedures as instructed by manufacturer and
railroad shall be followed at any time changes are made in the control
device or its modules, track circuit or wiring.
3. If any changes are made in the track circuit, or in adjustment and setup of
the control device, test shunts shall be applied or train moves observed as
instructed by the railroad to assure that the control device is capable of
operating with full approach track circuits.
4. Readjustments which affect the approach shall not be made to the control
device without first determining the cause that made such change
necessary.
5. Readjustments to island circuits shall be made in accordance with
manufacturer's and railroad's instructions. Cause of readjustment should
be determined.
6. Except where expressly permitted, the power switch shall be moved to the
"Off" position when removing, changing or replacing modules within the
control system.
7. When changing or replacing any modules within the control device, any
site-specific programming on the new module shall be the same as was
done on the original module. It should also be determined that any
replacement module is compatible with the intended functional
requirements of the system.
8. Field repair or modification of the control device modules is not
recommended. Repairs should be made conforming to Manual Part 1.5.1
(Recommended Instructions for the Installation and Maintenance of Solid
State Equipment), as well as manufacturer's and railroad's instructions.
Modifications should be made according to manufacturer's instructions
regarding upgrades and/or enhancements as deemed appropriate by the
railroad. Testing shall be done following repair or modification to assure
that all functions of modules are correct.
