BlueLinQ Pro controller EC541

The BlueLinQ Pro is a 1 to 6 pump monitor and controller, designed mainly to be used in municipal wastewater pumping stations. The software included in the BlueLinQ Pro is a further development of the EC 531 and PC 441 controllers. The controller consists of a 7” touch screen display, which can be connected to
a range of modules for monitoring and controlling any pump pit configuration. The back-plane DIN rail power and communication connections and slim-line design of the modules allows for simplified installation and space saving in any electrical cabinet. Monitoring of pump/pit data, viewing of alarms, manual control of pumps and changing of settings etc. can be made locally via the 7” touch screen or via the configuration software AquaProg on a PC, connected directly to the local service port or remotely via modem. Settings are password protected in two levels to avoid unauthorized or accidental changes.
