The #1 reason for service calls is because the generator did not start.
The #1 reason the generator did not start is due to a battery system failure.
And simply put, if your unit doesn't start, it can't perform. Therefore, your starting system (consisting of the battery, battery charger, starter, starter solenoid, cables, etc.) is of critical importance to maintaining dependable and reliable performance. And among these starting system elements, the battery is the most important. It also happens to be the item most likely to cause trouble.
Under ideal conditions, a battery can last 4-5 years or longer. Unfortunately most starting batteries work under average-to-poor environmental, application, and maintenance conditions. This shortens their life considerably. NFPA110, Standard for Emergency and Standby Power Systems, 2013 edition states that "it is recommended that lead-acid batteries be replaced every 24 to 30 months." Based on our experience, we recommend replacing small batteries every 2 years and large batteries every 3 years, using an industrial-grade battery specifically designed for standby generator duty. Remember, this isn't like waiting to replace your car battery until it fails. Wait that long and you risk not having emergency power when you desperately need it. Replacing your batteries every 2-3 years is the "cheapest insurance" you can buy to make sure your emergency generator is dependable and starts when needed.

Automatic Transfer Switch Maintenance may just be another line item on your service contract, but are you getting what you think you're getting? Some service companies just press the "test" button or visually inspect the switch and clean the exterior cabinet. But are they:
If they're not, what they're selling you isn't really maintenance, and not something you should be satisfied with when it comes to an important piece of equipment like your transfer switch - especially if you want to adhere to National Fire Protection Association (NFPA 110) standards. This is the standard Electro-Motion uses when it comes to transfer switch maintenance, the end result of which is a transfer switch that is as good as new and can be relied upon to do its job in the event of a power disruption.

Are you in the planning/design phase of retrofitting your elevator systems to be in compliance with current ASME codes and standards? If so, these new elevator systems require the installation of pre-signal relays. Why is this?
With old elevator controllers, it didn't matter if the Automatic Transfer Switch transferred when the elevator cars were moving. But now, when elevator controls are upgraded from relay logic to solid state controls, the cars can no longer be in motion when the Automatic Transfer Switch transfers between hot power sources. The solid state logic in the new elevator controllers cannot handle this and it can result in damage to the controller. To circumvent this problem, a pre-signal (a delay to transfer) is sent to the elevator controller prior to transfer, allowing cars to reach the nearest floor and open their doors. The system resets after the Automatic Transfer Switch transfers and the cars are then ready to move again.
Electro-Motion is experienced at installing pre-signal relays in the San Francisco Bay Area to address this issue. If you need to have pre-signal relays installed, call us today at 650-321-6169.
