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
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 permanently
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 hand held terminal
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
hand held terminal push-button is inoperative.
3-8 INTERLOCK optically isolated
internal circuit, this signal can be used to
delay the starting of the turbopump. It
requires a permanent closed contact before
starting the turbopump.
4-9 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.
Pin 3-8 must be shorted to allow the Turbo-V 1000HT
PCB 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.
