Upon receiving a request for assistance, our drive specialists will discuss the issues and any fault information available. We always attempt to troubleshoot using off-site assistance and remote support to provide a fast, cost-effective solution for our customers. In the case of this customer, the initial fault reported was F002 (pre-charging fault); but after further discussion and testing with site personnel, there were indeed additional issues with the unit. The F002 was the only fault displayed initially, but A017 (safe-off) and status locked in o008 (start inhibit) were also present.
An onsite repair was necessary, so we immediately dispatched an engineer to make the 6.5 hour trip to the location so he could be present early Monday morning. When onsite assistance is determined to be necessary based on the information collected, all the appropriate parts required to accomplish an onsite repair are organized and carried with the technician to the site to facilitate a speedy repair.
The drive was put through several functional tests to identify the defective components, and we also found an F026 issue for gating fault on IGD. The parts were replaced, and the system was retested to validate the repair before returning the VFD to normal service. The entire procedure was completed in less than eight hours. Our engineer remained at the facility for an extra day to monitor the operations of the systems to ensure everything was running smoothly.
The printing company was extremely pleased with our quick response and our engineer’s preparations to complete a fast repair. After a frustrating several days with their onsite engineer unable to diagnose the problem, it was a relief to be operational again quickly to save additional downtime and expense. We also took the time to make sure the onsite engineer understood the problem and provided guidance for avoiding a similar failure in the future.
