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
to obtain the desired capability. The following table describes the
signals available on the connector.

DESCRIPTION
Analog output Voltage of DC current drawn by the turbopump (pin 2 positive,
pin 1 negative). 2 Vdc ≡ 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.
Default value = 67 KRPM
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.
START signal 24 V, 60 mA, optically isolated output (pin 13 positive, pin 6
negative).
The output voltage will be present when the remote start is present until
NORMAL operation is reached.
