3.如果軌道電路或設備的調(diào)整和設定有任何變化，按照制造商和鐵路部門的要求，采用測試轉(zhuǎn)轍器或觀察列車移動，保證系統(tǒng)能完全運行軌道電路。
4.如果沒有首先確定改變的必要性，設備不得對系統(tǒng)再調(diào)整校準水平超出3%。如果沒有確定改變的必要性，可能會忽視斷裂路軌、損壞的捆綁物和耦合裝置或者發(fā)生故障的轉(zhuǎn)轍器。
5.島式電路再調(diào)整要求符合制造商和鐵路的指示。
6. 除非制造商明確表示允許，在設備去除、更換或者替換模塊之前，模塊或適當設備必須斷電。
7.在設備去除、更換或者替換模塊之前，新模塊任何站點規(guī)定的編程在是相同象原物模塊。
8.不建議對場地設備模塊進行修理或修改。修理作業(yè)要求符合手冊第1.5.1部分(固體設備設施和維護推薦規(guī)程)，和制造商和鐵路部門的指示。要求根據(jù)制造商的指示進行鐵路部門認可的相關升級和改進。對隨后的修理或修改進行測試，保證模塊的所有功能正常。

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.
