DESCRIPTION
Remote LOW SPEED, requires a permanently closed contact (relay contact,
transistor etc). When the first time contact closes, the turbopump runs at low
speed and when the contact opens, the turbopump reverts to high speed mode.
R2 INTERLOCK, requires a permanent closed contact to set at infinite the run-
up time.
After closure, when the contact is reopened, the run-up time is set to zero
minutes.
Remote STOP signal, requires a closed contact and it is used to stop the pump.
When the conract is closed, the turbopump and the interconnected devices are
stopped.
Remote RESET, requires a momentarily closed contact for at least 0.5 seconds
to reset the pump after failure.
ANALOG OUTPUT SPEED signal 0 to +10 Vdc proportional to pump rotational
speed 0 to 56000 RPM.
VENT VALVE output voltage.+24 Vdc without load; +6.5 Vdc with vent valve
load (430 Ohm). The output voltage is present when the turbopump is started,
and will remain present for about 5 more seconds after the turbopump is
stopped or after a power failure.
