Connection P1 – Logic Input Interconnections
Figure 9
All the logic input to the controller must be connected at J1 mating
connector. With the provided J1 mating connector (shipped with pin
3 and pin 8 shorted) make the connections with AWG 24, (0.24 mm2)
or smaller wire to the pins indicated in the following figure to obtain
the desired capability.

DESCRIPTION
Remote START/STOP optically isolated from the internal circuit, requires a
permanently closed contact (relay contact. transistor, etc.). When the contact
closes, the turbopump starts, and when the contact opens, the turbopump is
stopped.
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.
INTERLOCK optically isolated from the internal circuit, this signal can be used
to delay the starting of the turbopump. It requires a permanent closed contact
before starting the turbopump.
SYSTEM OVERRIDE optically isolated from the internal circuit, this signal is
used to stop the pump in emergency condition, requires a closed contact.
When the contact is closed, the turbopump and the interconnected devices are
stopped.
