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 = 1010Hz, 150W, 100°C
See following chart for more
details
Analog output proportional to
frequency (linear).
0V = 0Hz
10V = 1010Hz
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.
