COHERENT Relevant power supply maintenance HPC210-1 1700W,187V-253V.

Large equipment is often equipped with more functional fault diagnosis programs , We can make full use of the tips of the software , Narrow the scope of troubleshooting , But sometimes the diagnostic software indicates whether the damaged components are accurate , We need to expand our thinking , Further determine the fault location , solve the problem .

For the unstable operation of the machine or good and bad operation , Check the screws of the main circuit in the box 、 Whether the wiring terminal is loose （ During transportation, there may be ）、 Terminal oxidation, etc , Pay attention to whether there is a lot of dust inside the old power supply or the power supply with poor service environment （ You can blow it off with a wind gun ）; If there is a lot of oil in the box and the service life is very long , Irreparable shall be scrapped .

During maintenance , For the power supply required by the customer for maintenance , Do not remove the internal tie without permission 、 Control panel 、 Cut off the wiring or connect and change everywhere , It may cause interference to the whole machine or performance degradation , If returned , The problem of old power supply due to specification , Many don't have wiring diagrams , It may bring great difficulty to maintenance , It will be scrapped if it is serious , It will affect the reputation of customers or the company .

Old power supply , It cannot be repaired on site , When it needs to be returned to the head office , The connecting wires of the upper and lower boxes shall be returned together , For inspection and maintenance .

The returned power supply or main control board shall be provided with surface shockproof protection , Prevent the panel from being scratched 、 Deformation or device falling off , So as not to cause losses to the company , It will also bring trouble to the maintenance work .

The returned power supply or main control board shall be labeled , Indicate the detailed fault of the power supply on site 、 Office name, etc , It is convenient for maintenance technicians to analyze and repair , Sometimes, there is inconsistency between the test on the whole machine and the separate test . Our maintenance personnel will make relevant maintenance records according to the label , Do a good job in the maintenance and tracking of laser power supply , Increase the repair yield .

It has been repaired many times , To the customer that still can't be used , The wiring of the whole machine and other vulnerable parts shall be checked on site . Check the cause of the fault . Make on-site inspection records and return them at random .

To further determine the fault scope , The channel plates can be interchanged , Observe whether the fault phenomenon changes . When exchanging , Let the static electricity off your wrist first , And wear anti-static gloves , Exchange the middle channel plate with the right channel plate , Redo channel detection , Prompt at this time 29 Number slot damage , The fault location has changed , Prove that the middle channel plate is damaged .

The primary channel board is faulty , The rack power supply and scanning system cannot be started ,CT Machine diagnostic program prompt DMS There may be a problem with the power supply ( actually DMS The power supply is normal ). As the performance of the channel board further changes , The rack power supply and scanning system can start again , With CT The camera image begins to appear artifacts
