Connection P1
Logic Input Interconnections
P1 input connector
All the logic input to the controller must be connected at
J-1 mating connector. With the provided J1 mating
connector (shipped with pin 3 and pin 8 shorted) make
the connections with AWG 24, (0.24 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.

Remote LOW SPEED optically isolated from
the internal circuit, requires a permanently
closed contact (relay contact, transistor. etc.).
When the contact closes, the turbopump runs
at low speed and when the contact opens the
turbopump reverts to high speed mode. With
the remote mode operation selected, the front
panel push-button is inoperative.

pump to start if no interlock contact is connected. if,
after starting the pump, the interlock contact opens, it
has no effect on the operation and the pump continues
to turn.
