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
1-2
Analog output Voltage of power drawn by the
turbopump (pin 2 positive, pin 1 negative). 1
Vdc ≡ 50 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 (pin 12 positive, pin 5
negative). The output voltage will be present
when the low speed mode is selected, either
through the hand held terminal or the remote
signal.
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 pushbutton on hand held terminal is
pressed, or the remote start is present, until
NORMAL operation is reached.

7-14
R2 signal 24 V, 60 mA, optically isolated
output (pin 14 positive, pin 7 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 speed > speed threshold
R2 = OFF
b) If running speed < speed threshold
R2 = ON
If NO is selected:
a) If running speed > speed threshold
R2 = OFF
b) If running speed < speed threshold
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 detected.
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.
