Changing the Dip Switches inside the controller then cycling the power will activate the selected logic mode. Examples of common applications are detailed later in this manual but with an understanding of how the controller responds to various inputs in each of the modes the controller can be used for application other than what is suggested.

- Page 15 For example, the controller can be connected in series with a VFD controlled pump to provide additional control inputs or to utilise the nXt-DPC controller delay times. For even greatly flexibility in your installation the nXt-DPC controller can be used as a ‘module’ in a more complex control environment.

Page 16: Quick Guide: Drainage Mode, Float Connected To Pump
The Controller provides additional protections excluding dry run, start/stop delay times and pump start alternation. A float connected to the controller can provide high level alarm function. Parameter 020 must remain set to 0.0A to prevent underload alarming when the pump float interrupts pumping operation BIA-nXt-DPC3 Instruction Manual V1.0... -
Page 17: Quick Guide: Drainage Mode, Floats Connected To Control
Both pumps continue to run until the Lower Pump float switch is in the Off (Down) position. The controller alternates whichever pump starts first every startup cycle. Should the first pump shut down due to an alarm condition, the controller will automatically transfer duty to the second pump. BIA-nXt-DPC3 Instruction Manual V1.0... -
Page 18: Quick Guide: Transfer - Source/Destination Control
A float switch or probes at the source controls whether the pump will run or not depending on the liquid level. Should the level continue to drop despite a single pump running, the second pump will start when the level falls to the L2 (#7) position BIA-nXt-DPC3 Instruction Manual V1.0... -
