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
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).
2 Vdc ≡ 1 A.
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 signal or
RS 232.
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 RS 232, until NORMAL
operation is reached.

PIN
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
R2 = OFF
b) If
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 displayed on the front panel
display.
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.
