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.

Description
0V = no fail
24V = fail
Configurable output.
Default setting (win.177 = 0): 24V pump
in RAMP state, 0V = other state. If
win.177 = 1: 0V = pump in stop or FAIL
status, 24V = other state
24V = low speed active
0V = low speed not active
Programmable Set Point Out can be
related to: Frequency, Power, Time
Status or Pressure. See following figures
for more details. All the setting can be
done by: front panel or serial line
(win.101 to 105 and 162).
Programmable Set Point Out
Can be related to: Frequency, Power,
Time Status or Pressure. See following
figures for more details. All the setting
can be done by: front panel or serial line
(win.171 to 176).
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
