The CU 362 control unit is a combined controller and user-friendly control panel. The control panel consists of nine buttons and a large graphical LCD display. On the CU 362 operator display, the current status of the system is shown. The actual positions of the pumps, mixer and measuring sensors are shown in the display.

CU 362 inputs and outputs:

3 digital inputs 3 analog inputs for connection to

sensors with current (0-20 mA/4-20 mA) or voltage (0-10 V)

2 digital relay outputs, 240 VAC, 2 A Connection to battery backup (UPS)(optional) GENIbus communication (RS-485) Ethernet connection (VNC) Connection to fieldbus CIM modules

(CIM = Communication Interface Module):
– CIM 200 (Modbus via RS-485) – CIM 250 (Modbus and SMS via GSM/GPRS) – CIM 270 (GRM) (GRM = Grundfos Remote Management).
