PIN
DESCRIPTION
2-1
Analog output Voltage of power drawn by the
turbopump (pin 2 positive, pin 1 negative). 1
Vdc proportional to 100 W.
4-11
R1 signal 24 V, 60 mA optically isolated output
(pin 11 positive, pin 4 negative). The output
Voltage will be present when the rotational
speed of the pump is higher than the selected
speed threshold
5-12
LOW SPEED signal, 24 V, 60 mA, optically
isolated
output
negative). The output Voltage will be present
when the low speed mode is selected, either
through, the front panel, the remote segnal, or
RS 232/RS 485.
6-13
START signal 24 V, 60 mA, optically isolated
output (pin 13 positive, pin 6 negative). The
output Voltage will be present when the
START push-button on front panel is pressed
or the remote start is present, or the function
has been requested by or RS 232/RS 485,
until NORMAL operation is reached.
7-14
R2 signal 24 V, 60 mA, optically isolated output
(pin 14 positive, pin 7 negative).
The ouput Voltage will be present upon the
programmed condition delay YES or delay NO
(see the cycle diagram in the following pages).
If YES is selected, R2 is off and the output is
zero over all run up time, than:
If running speed > speed threshold
a)
R2 = OFF
If running speed < speed threshold
b)
R2 = OFF
If NO is selected:
If running speed > speed threshold
a)
R2 = OFF
If running speed < speed threshold
b)
R2 = ON
8-15
FAULT signal 24 V, 60 mA, optically isolated
output (pin 15 positive, pin 8 negative).
The output Voltage will be present when a fault
condition is displayed on the front panel
display.
9-1
Analog output voltage ( 0 – 10 V) proportional
to pump speed (pin 9 positive, pin 1 negative).
Stop Speed Reading
This function allows the user to read the pump
rotational frequency (window 203) even after a stop
command. The function can be activated/deactivated
by serial line (window 167).
If activated, all the related functions (set point out,
output voltage, ...) will follow the frequency reading.

PURGE-VENT
5
The inegrated purge-vent valves (if present on the
pump) can be driven by the controller, in this case use
the "purge-vent valves cable" reported in the "ordrable
parts" table.
The Turbo-V 3K-T pump can integrates the .purge. and
.vent valves.
The two valves are Normally Closed so if a power fail
occur, the valves will remain closed.
The valve operating mode can be set by serial line by
win.125 or by front panel using the "program menu",
see following diagram for details.
Note that the vent and purge valve can also be
controlled by means of the serial connection (see the
following diagram for details).
