PIN DESCRIPTION
2-1 Analog output Voltage of power drawn by the
turbopump (pin 2 positive, pin 1 negative). 1
Vdc proportional to 100 W.
4-11 K1 signal 24 V, 60 mA, optically isolated
output (pin 11 positive, pin 4 negative). The
output Voltage will be present when the
rotational speed of the pump is higher than
the selected speed threshold.
5-12 LOW SPEED signal, 24 V, 60 mA, optically
isolated output (pin 12 positive, pin 5
negative). The output Voltage will be present
when the low speed mode is selected. either
through. the front panel. the remote signal, or
RS 232/RS 422/RS 485.
6-13 START signal 24 V, 60 mA, optically isolated
output (pin 13 positive, pin 6 negative). The
output Voltage will be present when the
START push-button on front panel is pressed
or the remote start is present. or the function
has been requested by or RS 232/RS 422/
RS 485, until NORMAL operation is reached.
7-14 K2 signal 24 V, 60 mA, optically isolated
output (pin 14 positive, pin 7 negative).
The output Voltage will be present upon the
programmed condition delay YES or delay
NO (see the cycle diagram in the following
pages).
If YES is selected, K2 is off and the output is
zero over all run up time, then:
a) If running speed > speed threshold
K2 = OFF
b) If running speed < speed threshold
K2 = ON
If NO is selected:
a) If running speed > speed threshold
K2 = OFF
b) If running speed < speed threshold
K2 = ON
8-15 FAULT signal 24 V, 60 mA, optically isolated
output (pin 15 positive pin 8 negative).
The output Voltage will be present when a
fault condition is displayed on the front panel
display.
9-1 Analog output voltage (0 - 10 V) proportional
to pump speed
pin 1 negative).
(pin 9 positive,
The following figure shows a typical logic output
connection (relay coil) but any other device may be
connected e.g. a LED, a computer, etc., and the related
simplified circuit of the controller.
Typical output connection
Controller-to-Pump Connection
A five-meter long cable is to connect the controller to
the pump. The following figures show the controller
output connector configuration where pins:
•
A-F = upper bearing temperature sensor
•
A-G = lower bearing temperature sensor
•
B-C-D = 120 Vac 3-phase output to pump motor
stator
•
E = ground
