Does the variable-frequency pump start automatically after a power fluctuation?
Thread Content
Can variable-frequency pumps start automatically after a power fluctuation? Recently we experienced several power fluctuations, and some pumps were able to start on their own while others could not. Is this due to issues with the motor settings or something else? I remember that in the past it was necessary to restart the pumps manually on-site in order for them to start; this time, however, they started automatically
With a chain? It won’t start automatically if the interlock is disabled
Is the interlock located in the distribution room? At least it is not interlocked with the process
Our key operating pumps are equipped with restarters; they can resume operation within 10 seconds after a power outage, and reach their normal speed within 6 seconds after the motor starts up.
The automatic start of the inverter is conditional: firstly, it must be in a state with no fault alarms; secondly, the electrical interlocks must meet the conditions for automatic start; and thirdly, the output power of the inverter at the moment of automatic start should not be too high.
