Analogue input 0-10V
The analogue input 0-10V is screen-printed at the base of the 18-pole terminal board:
-
A1V
(terminal 9): Positive pole
-
GND
(terminal 10): Negative pole
-
A2V
(terminal 4): Positive pole
-
GND
(terminal 5): Negative pole
The function associated with the analogue input A1V is that of
regulating the pump rotation speed in proportion to the input
voltage 0-10V itself
(see par. 7.1.3 and par. 9). The input A2V is not enabled.
See
Figure 6
for an example of connection.
Figure 6: Example of Connection of Analogue Input
N.B: The 0-10V analogue input is mutually exclusive with the NTC type temperature sensor T connected to the same poles of the 18-
pole terminal block.
