Connection J2
Logic Output Interconnections
Logic output connector
All the logic output from the controller must be
connected at P2 mating connector. With the optional
P2 mating connector make the connection with AWG
24 (0.25 mm ) or smaller wire to the pins indicated in
the figure to obtain the desired capability. The following
table describes the signals available on the connector.
PIN
DESCRIPTION
8-15
Analog output Voltage of DC current drawn
by the turbopump (pin 8 positive,
negative). 1 Vdc proportional to 2,5 A.
1-10
RELAY 1 signal 24 V. 60 mA, optically
isolated output (pin 10 positive, pin 1
negative). The output Voltage will be present
when the rotational speed of the pump is
higher
than
the
threshold.
4-12
LOW SPEED signal, 24 V, 60 mA, optically
isolated output (pin 12 positive, pin 4
negative). The output Voltage will be present
when the low speed mode is selected either
through the front panel the remote signal, or
serial port.
3-11
START signal 24 V. 60 mA, optically isolated
output (pin 11 positive, pin 3 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
RS 232, until NORMAL operation is reached.

2-10
RELAY2 signal 24 V. 60 mA, optically isolated
output (pin 10 positive, pin 2 negative).
The output 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
is zero over all run up time, then:
a. If
running
R2 = OFF
b. If
running
R2 = ON
If NO is selected:
a. If
running
R2 = OFF
b. If running speed < speed threshold
R2 = OFF

The output Voltage will be present when a fault
condition is displayed on the front panel
display.
7-14
Analog output voltage (0÷10 V) of pump speed
(pin 7 positive, pin 14 negative).
The following figure shows a typical logic output
connection (relay coil) but any other device may be
connected e.g. a LED, a computer, etc., and the related
simplified circuit of the controller.
