Q&A
The switching method is different, MTS is manual, and ATS is automatic. MTS needs manual switching to change sources, but ATS monitors the utility power and changes sources automatically when a power failure occurs.
Q: How does an ATS start a generator?
During a testing or an actual power failure, is a time delay before the ATS sends a signal to your generator, starting it. When the voltage and frequency of the generator are acceptable by the voltage sensing network, it sends a signal over to the mechanism. Then it will open up normal power and close the generator.
Q: What are the common issues of ATS?
Tripped Circuit Breakers Power surges can trip the circuit breaker that provides power to the ATS.
It is an exceedingly common issue and also should check before further examining ATS issues.
Transient Voltage Transient voltage can damage the sensitive components in the ATS.
As the voltage flows into the circuit board, it can cause damage to the control boards that can prevent proper operation.
The best way to protect an ATS from the hazards of transient voltage is to ensure the proper functioning of the transient voltage surge protector.
Damaged Wires ATS controllers use a standard two-wire start system.
When the utility power is interrupted, a relay that is held open by utility power closes, allowing these two wires to come together, causing the generator to start.
When the wires are damaged or incorrectly connected, they may not make this connection.
Bad Controller A damaged controller in an ATS can fail to send the appropriate signals to the generator when a power outage occurs.
However, not all controllers need replacement when a failure is suspected.
Many can be repaired and reprogrammed.
Damaged Solenoids Solenoids can cycle too fast which causes intense heat to build up.
This can cause it to burn out and fail.
They can also fail following damage during maintenance or through the build-up of dirt and grime within the generator.
Q: What is the difference between CB Class and PC Class?
PC class uses mechanical + electronic conversion action lock, while the CB class uses electronic conversion action lock.
