RESET Repairs and Restores Mitsubishi Wind Turbine Controllers
Though based on a simple and ancient concept, modern Wind Turbines are complex, high-tech machines. Multiple components must work in a coordinated and optimized way to adjust to varied weather conditions and wind directions. This includes, yaw, blade pitch, monitoring and controlling of rotational tolerances, and maintaining safe and optimal operating speeds. In order to do this, these multiple components in the Mitsubishi Turbines are controlled by a Multi-purpose Remote Controller or MRC.

The MRC is the brains of the turbine, controlling its efficient operation and safe function, and making them an essential operating component. When they fail, there is an immediate negative impact on turbine function and production. MRC failure often leads to reduced generating capacity and efficiency, and it can even cause complete shutdown of the unit.

In the past, MRC failure has been extremely costly to turbine owners and operators. MRC repairs are often expensive and can be inconvenient, and many turbine owners end up just replacing them. Enter RESET, a company that specializes in hardware repair. RESET has long been the leader in repairing parts no longer supported by an OEM, and we put that expertise to use in the creation of a unique approach to repairing existing Mitsubishi MRCs. Through this approach, RESET will repair your existing Mitsubishi MRC for a fraction of the cost of purchasing a new unit, and get your turbine up and running again in no time.

So how do we do it? Through mastery of the diagnostic, repair, and testing procedures required.

RESET has invested in the design and creation of our own in-house turbine simulator that allows us to quickly, efficiently, and accurately identify and repair or replace the non-functional MRC component(s). Then, once repaired, the MRC is returned to the simulator for thorough bench testing and confirmation of repair before being returned to the owner or operator.

How to Know If Your MCR Has Failed or Is Failing
How do you know if you need to have your MRC serviced or repaired? When MRCs fail there are a variety of indicators including:
o Wind curtailment
o Communication issues or failures
o Error codes: F51; F77; F70 UPS abnormal; or F76 Communication Error
o Failure to yaw
o Failure to pitch
o Locking-up or freezing

All of these indicators can have a negative impact on production and efficiency, resulting in lost revenue. RESET will get your faulty MCR back to working order and test it to ensure that it will perform in the field, potentially extending the life of your wind turbine for many years.

How does the process work? First, the defective unit (MRC – multi-purpose remote controllers) is removed by the owner or operator and sent, via mail or parcel service, to RESET’s state-of- the-art repair facility. Upon arrival, each unit is cataloged in our inventory and repair database for process tracking and accuracy. Units go through our full diagnostics protocol and assessment to determine incoming failure
status, and RESET’s highly-skilled technicians are assigned to troubleshoot the exact failure and identify the proper repair course.

Repairs and component replacements are done to our exacting standards per our diagnostic assessment. After the repairs are complete, the unit is FULLY TESTED through the RESET wind turbine simulator that was created by our in-house engineering team.

What exactly does the Simulator Simulate?
RESET’s turbine simulator mimics the data output that would be created by a physical wind turbine. Through our groundbreaking proprietary software, RESET can input wind speed & direction variables and other data to make the MRC function as it would if it was operating in a physical turbine setting. This complex, programmable logic was developed specifically for this purpose and is what allows RESET
to confidently recommission faulty MRCs back into service.

If you are a Mitsubishi Wind Turbine Owner or operator and you know or suspect that you have a faulty MRC in one or more of your turbines, don’t unnecessarily overspend on replacement parts. Repairing your MRC through our process is simple, cost-effective, and efficient and will often lead directly to reduced down-time versus the more costly replacement option.

It’s simple: Don’t Replace it, RESET it.
