12.2 Parameter list
The table below shows which measured values the CU 351 can
receive via its analog inputs. Figures 114 to 115 117 show where
the values can be measured.
No Parameter
1 Flow rate
2 Discharge pressure
3 Differential pressure, external
4 Inlet pressure
5 Differential pressure, pump
6 Differential pressure, inlet
7 Differential pressure, outlet
8 Tank level, discharge side
9 Tank level, suction side
10 Return pipe temperature, external
11 Flow pipe temperature
12 Return pipe temperature
13 Differential temperature
14 External pressure
15 Series 2000, differential pressure
16 Series 2000, flow rate
17 System pressure
Not shown Ambient temperature*
Not shown 0-100 % signal**
* The ambient temperature is typically the temperature in the
room where the Control MPC is located.
** A 0-100 % signal from an external controller. It can for instance
be a 0-10 V signal.
