Check components of the thyristor assembly

In the event of a thyristor assembly failing, establish which component has failed:
● Thyristor (by resistance measurement)
● Thyristor electronics (by replacement)
● Fiber-optic cables

NOTICE
Destruction of the CompactFlash card
The CompactFlash card must only be inserted or removed when the power is off.
Otherwise there is a risk of data loss or damage to the card, which would prevent
commissioning of the drive.
● Only remove or insert the CompactFlash card when the power is switched off.
Note
Invalid software key
The software key is associated with the serial number of the CompactFlash card. If you
overwrite the software key of the new CompactFlash card with the previous CompactFlash
card, the new CompactFlash card is not operational.
Consequently, use the software key of the new CompactFlash card.
When a thyristor fault message is output, the fault value indicates which thyristor is affected.
Check the thyristor resistance while it is installed.
Send the replaced thyristor electronic boards to the manufacturer for testing.
Replace the fiber-optic cables according to the instructions for laying fiber-optic cables.
