At ELTIV, we will find and fix the fault and ensure you receive a fully functional card. But if the fault is actually somewhere else in the system, it is very likely that the card will fail again.
Here are a couple of steps to consider:
Make note of the symptoms the installation exhibits
Most of the errors will point to one or the other of the components in the system. Your competent electrician or instrument technician can easily trace back the fault to the appropriate component (I/O card, processor, power supply, etc)
Once the fault identified, try changing the position of the card in the mounting rack/chasis. This will help you decide if the fault is on the backplane or on the card itself.
If the fault still exists, means that the fault is on the card. If the card has multiple channels, try to move your field wiring to a spare channel. If successful, you have a faulty channel.
If the fault still exists, try swapping the card with a known working identical card from a “sister” system or a spare.
If the fault does not exhibit, you have identified the faulty card.
If the fault persists after swapping the cards, the source of your fault is somewhere else in the system and you have to continue the process, until the source of the fault is identified.
There are a few methods that can be sought of like: (a) pulling cards out and inserting them back one by one until the fault occurs (b) check wiring for lose connections (c) try restarting the system and monitoring basic characteristics
Once you have identified the faulty card, write the symptom and fault down and send the card to us, together with any relevant information like schematics, manufacturer, model, function, name of the parent system, etc.
It is also crucial that we know of any past attempts to repair the card. Once components have been replaced, we cannot guarantee that we will restore the card back to its original specifications.
