Sir,
I am using crate LTC-002 since last 6 years. Now Some modules (LC-302/8, LC-111, LC-403U)have gone bad. it seems that these modules are outdated and not in your current production. It is impossible to send these modules to your place for Repair from India. Schematic for Crate-LTC-002 and for these modules were not supplied in 2005 but as these modules are of outdated design for you, I request  L-card technical support team to give the schematics so that i can try to repair these modules at my place. This will be a very big help from you.

Regards,

Please mail any detail regarding these circuits to ravindrasing@gmail.com.

Thank You all

Is it possible to still buy LC-302/8, LC-111, LC-403U from L-card? If Yes then what will be the price for 10 Modules of each type?

To Ravindra Singh.
Крейтовая система LTC давно снята с производства и уже не соответствует современному техническому уровню. Я полагаю, что нецелесообразно вкладывать силы и деньги в самостоятельный ремонт, учитывая, что Вы не можете передать крейт LTC в L-Card. Современной альтернативой системы LTC является система LTR:

а именно: современной альтернативой крейта
LTC-002 являются крейты LTR-EU-8/16. Вместо модуль ЦАП  LC-302/8 может быть использован LTR34-8,

вместо АЦП  LC-111  - LTR11,
http://lcard.ru/products/ltr/ltr11 ,
вместо LC-403U - LTR43.

Но система LTR не совместима с LTC программно и конструктивно. От этой совместимости разработчикам пришлось отказаться, чтобы обеспечить развитие системы. Крейтовая система LTR активно выпускается с 2005 года и в ней заложены технические решения, которые создают перспективы и для её дальнейшего развития и длительного выпуска. По крейтовой систем LTR оказывается техническая поддержка, предоставляется бесплатное ПО LGraph2 http://lcard.ru/lgraph .

I/'ll try to summarize the response of our leading engineer. It is economially unreaonable to invest into the repairment of absolutely obsolete devices. Schematic will be of no help - diagnostic and repair is a serious quest even for our qualified servicemen. These modules have modern analogies with good perspective: LTR system http://lcard.ru/products/ltr/ltr

Buying LC-xxx now is impossible - the stock remaining from old days had long since been exhausted.

If you could send us by e-mail the datails of your task, we could do our best to supply recommendations for organizing your measurements on the basis of the current devices.

Thank you Mr. Alexander Garmanov & Support team for your reply. I know that repairing LC-xxx cards is almost impossible. I too have considered upgrading my machine to LTR in near future. But as the purchasing process takes time and proper planning, I insist on repair of the old modules. If you can email me the schematics, I can try to repair these modules as my project is getting delayed because of the fault. I really need the circuits. Thank You

Dear Mr.Ravindra Singh,
Graduated spesialists which can repair LTC-002 and its modules should:
change all electrolytic capacitors of whole create, I mean inside power supply block inside  LTC-002, inside LTC-xx modules.
Еlectrolytic capacitors has short servise period in hot climate.
Recommended electrolytic capacitor type for exchange - EXR (Hitano) or another  LOW-ESR Capacitors.
They should be changed with item  factic rating.
I give these recommendanions in accordance to "as is" concept without any guaranties.
You don/'t need schematics in this case.
I/'m really sorry but more complicated repairings can/'t be proceeded in your situation.

Change to:
http://www.hitano.com.tw/PDF/EXR_121214.pdf
Save original poratity ("+", "-") of capacitors on boards!

Save original polarity...
