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
connections with AWG 24 (0.25 mm
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 DC power drawn by
the turbopump (pin 2 positive, pin 1 negative).
1 Vdc ≡ 10 W
1-9 Analog output voltage (0 - 10 V) of pump
speed (pin 9 positive, pin 1 negative).
4-11 RELAY 1 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
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 24V, 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
R2 = OFF
b) If
R2 = ON
If NO is selected:
a)
R2 = OFF
b)
R2 = ON
8-15 FAULT signal 24V, 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.
