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.
PIN DESCRIPTION
1-6 Remote START/STOP optically isolated from
the internal circuit, requires a
closed contact (relay contact transistor, etc. ).
When the contact closes. the turbopump
starts, and when the contact opens. the
turbopump is stopped. With the remote mode
operation selected, the front panel push-
button is inoperative.
2-7 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.

starting the turbopump.
4-9 SYSTEM OVERRIDE optically isolated from

Turbo-V 2000HT 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.
The following figure shows a typical contact logic input
connection and the related simplified circuit of the
controller.

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) 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.
