How do you test ATS?
To begin the test, close the normal source circuit breaker. The switch controller will light up the available LED when right voltage is sensed. If the source 1 stages the automatic transfer switch mechanism, the LED at source 1 will turn on. Verify the phase to phase voltages at the utility line terminals.
How often should ATS be tested?
Any automatic transfer switch in an emergency or standby power system should be should be tested monthly in accordance with NFPA 110.
What does ATS stand for in HVAC?
An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source.
How do you troubleshoot an automatic transfer switch?
When the ATS fails to transfer to the utility, it can be because the service disconnect breaker is open or the voltage is unacceptable. When this happens, you can reset the service disconnect breaker or simply wait for the voltage to return to acceptable levels.
How do you maintain ATS?
Test all AC connections and adjust if needed.
- Check The Generator Line Voltage.
- Look Over all Control wires & relays.
- Check exercise clock.
- Test ATS for proper operation.
- Clean internal & external of ATS.
- Submit completed inspection report.
What is automatic transfer switch PDF?
Switches may be manually or automatically operated. An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
What causes ATS failure?
Modern automatic transfer switches (ATSs) contain sensitive components that are highly susceptible to damage caused by transient voltage. Voltage monitoring control boards and control power supplies commonly fail due to damage caused by transient voltage. These failure modes result in ATS inoperability.
How do you clean a transfer switch?
To conduct a proper deep clean on a transfer switch, you’ll need to remove the arc chutes or transfer switch barriers so you can take a look at the contacts within. If you see any surface deposits or buildup of dirt and grime, wipe them away immediately with a clean and dry cloth.

What are ATS routes?
An ATS route is a specified route designed for channeling the flow of air traffic as necessary for the management of air traffic operations.
