J1 input connector
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 mm
2
) or smaller
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
1-14
Remote START/STOP S1 optically isolated from
the internal circuit, requires a 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.
2-15
Remote START/STOP S2 optically isolated from
the internal circuit, requires a permanently closed
contact (relay contact. transistor, etc.). When the
contact closes the turbopump starts at low speed
and when the contact opens, the turbopump is
stopped. With the remote mode operation
selected, the front panel push-button is
inoperative.
3-16
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.
4-17
Remote/Local signal 24 V, 60 mA, optically
isolated output (pin 17 positive, pin 4 negative).
The output Voltage will be present when the
controller is configured in Remote Mode.
5-17
∗
START S1 signal 24 V, 60 mA, optically isolated
output (pin 17 positive, pin 5 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
RS 232/422/485, until NORMAL operation is
reached.
