DCC - Model 11946 - Backup Float Switch Pump Controllers (BUPC) - Brochure

The Backup Pump Controller (BUPC) model 11946 is a control and display unit which automatically controls up to two single speed pumps in the event of a primary controller failure. It is designed to serve as a backup controller in a duplex pump control system for lift stations and other fluid pump-down applications. The unit can also function as a primary duplex float switch controller. The BUPC provides built-in pump alternation, pump start time delay, and a system alarm to indicate primary control failure. It is designed to work with up to five float switches. When operating as a backup controller, it will only control the pumps if the primary controller failed to maintain a liquid level within the normal operating limits. If the BUPC senses that the level has exceeded the primary control upper limit, then it will take over and operate the pumps.
