Generator Maintenance
We've been experiencing an alarm lately on our diesel generator during its' weekly test. The alarm is really quite loud and annoying but I'm glad we got it. It gave us a chance to become more familiar with a system we don't often think about. And, because many of our staff are new since the generator was installed several years ago, we needed the opportunity to learn.
The display on the generator control panel was un-readable, making our troubleshooting efforts difficult right from the start. We could barely make-out something something about a low coolant level. We all knew that a company in town came by once in a while to keep fuel in the unit and we knew the generator fired-up every Sunday for a test. You can't help but hear the big diesel motor running when it fires-off. Beyond that, it was decided, we didn't know much else about it. The two staff that were responsible for the installation of that particular system were no longer employed with us.
We checked the manufacturers web site and found a certified repair vendor in town. We asked them to find the cause of the alarm (we had just been resetting it whenever it went off) and also perform some maintenance on the engine (oil, coolant, filter changes, etc.) The technician was really knowledgeable and inspired confidence. He spent some time with our staff, demonstrating some basic operations and pointing out the documentation that was locked-up in one of the control cabinets. We're still a long way from being experts but at least we feel a lot more comfortable with this critical but seldom used system. Now we plan to perform some "real-live" testing with the system at some point in the near future.
For me, the lesson learned here is to be on constant look-out for opportunities to increase knowledge, experience, and comfort with all our systems. I think sometimes we tend to shy away from areas we don't know much about but only through embracing those opportunities to learn, often times through just plain old curiosity, do we make ourselves better.
