    Automatic Transfer Switch Maintenance

    Electro-Motion performs Automatic Transfer Switch Maintenance (ATSM) in accordance with the National Fire Protection Association 110, Standard for Emergency and Standby Power Systems. Few companies perform this work because of the specialized knowledge required, and even fewer perform this work to the NFPA standard.

    The Automatic Transfer Switch (ATS) is a critical component of your emergency backup system. The ATS detects when utility power is interrupted, and signals the generator to start. Once the generator reaches operating speed, typically within 7-10 seconds, the ATS transfers the building load to the generator. Once utility power is restored, the ATS re-transfers the building load back to utility power and initiates the generator cool-down and shut-off process. Without proper function of the ATS, your emergency backup power system may not operate when needed.

    A comprehensive maintenance program is the best insurance your ATS will perform when needed, NFPA calls for periodic inspection & testing, in addition to annual maintenance. Annual maintenance involves disassembly of the mechanical side to inspect for evidence of overheating or damage. Contacts and arc chutes may require replacement if pitted or cracked. The ATS should be cleaned to eliminate dirt and dust, and moving parts should be lubricated. Electro-Motion's ATSM protocol meets all NFPA requirements and ensures your ATS is in good working order when needed.
