Engineers save the day for customer who was experiencing problems with tripping DC drive

A Sprint Electric drive saved the day for a customer who was experiencing problems on extruding lines because of a tripping DC drive. The machine was nearly 20 years old and had been reliable until the spurious tripping grew more frequent.
 
The customer, after replacing everything associated with the Siemens DC drive, contacted our technical services department for help. The fault was diagnosed over the phone to be an internal power supply issue and the north east based customer was offered two options:

• Have the drive removed and brought to our Huddersfield service centre for repair, which could take a minimum of 2-3 days depending on spares availability.
• Have it retrofitted with a Sprint Electric modern equivalent, which could be done within 10 hours’ downtime of the machine.

Even though the second option was more expensive, the customer chose it because minimising downtime was crucial. The company knew of the reliability and cost effectiveness of Sprint’s product from other machines it had. The job was completed on time and production was reliable once more. In the event of similar drives failing on other machines, the faulty Siemens drive was inspected for repair as a spare.
