  • Prior to contracting with Electro-Motion, we did our own maintenance, which was very little due to lack of qualified staff and budget concerns. We have four diesel units at our various high schools and none were in great operating condition. Electro-Motion came in and provided us with professional services and brought our generators up to full operational capability. We are also considered emergency shelters due to unforseen natural disasters; and we need our generators to support this type of operation.

    Common Maintenance Mistakes: Failure to Maintain Your Automatic Transfer Switch

    August 30, 2013

    Unless you maintain your Automatic Transfer Switch (ATS) each year, you risk failure of your emergency power system just when you need it -- and that’s when the power goes out.

    All the ATS makers, without exception, recommend an annual maintenance. This includes Zenith, ASCO, Westinghouse, Onan, Kohler, etc. The makers know their equipment best, so if they require it every year, it’s important to listen.

    NFPA110 (the National Fire Protection Association) calls for a yearly maintenance on all ATS units. NFPA is the most commonly used standard in our industry, and your local Fire Marshall probably uses this standard as well. Please call us for a copy if you don’t have one.

    Your ATS is 50% of your system. Obviously, if your generator set doesn’t perform you won’t have emergency power. Likewise, if your Automatic Transfer Switch doesn’t perform, you won’t have emergency power. Both are critical, and both should be maintained as intensively as possible.

    Important next steps:

    1) Check Your Records. If you haven’t had this ATS maintenance work done in the last year, that work is due.
    2) Get Information: Begin to gather the information you’ll need to understand how this work must be performed and how to manage the potential internal disruption. Call us and ask for “Automatic Transfer Switch maintenance...what do I need to know?”  We’d be happy to talk you through the impact to your facilities.
    3) Call us to Schedule the Work. We are flexible and can schedule this work during off-hours to minimize disruptions..

    Remember: Your maintenance program must include an Automatic Transfer Switch Maintenance or -- by definition -- it is not comprehensive!
