Connection J2 - Logic Output Interconnections

Figure 11
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.

Logic output connector
DESCRIPTION
Analog output Voltage of DC current drawn by the turbopump (pin 2 positive pin
1 negative). 1 Vdc proportional to 1 A.
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.
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 front panel. the remote signal, or RS 232.
START signal 24 V, 60 mA, optically isolated output (pin 13 positive, pin 8
egative).
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.
