Analog Output
When the analog output is set to provide pressure signal, the voltage
level is proportional to pressure level and it is generated by control
unit elaborating the independent input by the active gauge.
If the Programmable Analog Output is related to the pressure read by
an external gauge, the controller doesn't replicate exactly the signal
coming from the gauge; the controller converts the gauge signal in the
range from 0 to 10V.
The conversion formula is the following:
V
out
Where:
Vg is the gauge output voltage;
Vout is the Analog Output voltage;

Description
Programmable analog output.
Can be related to : frequency,
power, pump temperature
(linear) or pressure read
by the external gauge.
The setting can be done by:
front panel or serial line
(win.111).
0V = 0Hz, 0W, 0°C
10V = 963Hz, 150W, 100°C
