PIN DESCRIPTION
1-9 Remote START/STOP S1 optically isolated
from the internal
permanently closed contact (relay contact,
transistor, etc.). When the contact closes the
turbopump starts at high speed and when the
contact opens, the turbopump is stopped.
With the remote mode operation selected, the
front panel push-button is inoperative.

output (open collector).
The output is activated when the START
push-button on front panel is pressed or the
remote start is present or the function has
been requested by RS 232/422/485, until
NORMAL operation is reached.
4-12 Normal S1 signal 24 V 60 mA, isolated relay
∗
output (open collector).
The output is activated when the rotational
speed of the pump is higher than the selected
high speed threshold.

activated when the pump is in its deceleration
phase, with exception of an

output (open collector).
The output is activated when a fault condition
is displayed on the front panel display.

relay output (open collector).
The output is activated when the controller is
configured in Remote Mode.

The 120 Vac, 1 A maximum (independent of line
Voltage) output Voltage is present when the main
power switch is set to 1 position and after START push-
button is pressed and will remain present until a fault
condition is displayed on the front panel display or the
turbopump is stopped.
The connector J7 is for vent device, forepump
connector coils, pump cooling fan etc.
To make connections, remove the plug and wire the
pins (maximum wire size 18 AWG, 1 mm²) as indicated
in the figure to obtain the desired capability.
Forepump relay coil is an independent user supplied
item.
