W-CTRL-SK-712/w-3-1,5 (3,7A)-PKG

W-CTRL-SK-712/w pump operation, control and protection unit provides fluent stepless regulation of each pump rotation speed with the help of frequency converters (FC) and is used to operate multipump assemblies in the following systems:

•Circulation systems

•Pressure boost systems

Unit main functions:

•Automatic and manual modes of pumps operation;

•Programmable pumps parameters, pressure (difference) parameters and other system parameters

•Displaying of technological parameters in course of system operation

•Fault warning with code displaying

•Accessing stand-by pumps in case the operating ones are out of order

•Cyclic switch of the pumps to ensure their smooth wear

•Connection to peak pumps through external signals

•Pump motors overtemperature protection using the PTC/WSK contact element

•Opportunity to work with 4-20мA analog sensors

•Remote switching

•External signaling or data collection device outputs
