ABB ACQ810 - Sleep and boost function
Built within ABB's ACQ810 variable-speed drive is a sleep and boost function. This function detects pressure drops in the pipes and runs the pump to boost it prior to shut down. Pumping restarts when the pressure falls below the minimum level. This function extends the pump's sleep time and helps save energy. Also the lifetime of the pump and motor increase when non-productive running time is avoided.
