INTERCONNECTIONS
The following paragraphs describe the Turbo-V
3K-G interconnections.
J1 – REMOTE I/O
At power-on the controller goes into "Remote I/O"
mode, even if it was in "Serial" mode before
power-down.
This connector carries all the input and output sig-
nals to remote control the Turbo-V 3K-G.
It is a 15-pins D type connector; the available sig-
nals are detailed in the table, the following para-
graphs describe the signal characteristics and use.

Signals description
START/STOP: input signal to start or stop the
pump. With the supplied cover connector the
START/STOP (+) signal is connected to the +24
Vdc pin and the START/STOP (-) signal to the
GROUND pin: in this condition the pump auto-
matically starts as soon as the controller recog-
nises the input supply ("Plug & Pump").

TECHNICAL INFORMATION
INTERLOCK: input signal to confirm the pump ro-
tation. With the supplied cover connector the
INTERLOCK (+) signal is connected to the +24
Vdc pin and the INTERLOCK (-) signal to the
GROUND pin, in this condition the pump auto-
matically starts as soon as the controller recog-
nises the input supply ("Plug & Pump"). These
pins must be always connected to +24V and
ground to allow pump running.
SPEED SETTING: PWM input signal to set the
pump speed. The PWM signal characteristics must
be the following:
•
frequency: 100 Hz +/-20%
•
amplitude: high level from 12 to 24 V
•
duty cycle range: from 25% to 75%
corresponding to a pump speed from 500 Hz
to 530 Hz linearly (see the following diagram).
NOTE
High Speed is the nominal rotational frequency of
the pump (530 Hz). Low Speed (510 Hz) corre-
sponds to the rotational frequency for a stand by
status. Users can set rotational frequency between
these two values.
If any signal isn't applied (no connection) the driv-
ing frequency is set to "Maximum excitation fre-
quency" (the default value is 530 Hz; it is settable
via serial line by means of window 121: see the
serial command table).
If a continuous signal is applied (pin 5 connected
to pin 9) the driving frequency is set to "Low
Speed" (the default value is 510 Hz; it is settable
via serial line by means of window 117: see the
serial command table).
The "Low Speed" function can also be activated by
serial line with win.001, and the low speed value
can be adjusted via serial command win.117.
