b.1.1 Valve Connection to FSV10
Connect the two valve solenoid lead wires (E1 and E2) to pins 1 and 2 of
the 9 pin “D” connector. There is no polarity on these connections.
b.1.2 Input Reference Signal Connection
Connect the desired analog reference signal input (0 to 5 VDC or 4 to 20
mA) to the appropriate pin locations on the 9 pin “D” connector of the
FSV10. The FSV10 will recognize automatically which signal is being pro-
vided. If both are connected, the FSV10 will give priority to the 4 to 20 mA
signal when that signal is greater than 2 mA.
a) When using the 0 to 5 VDC reference signal, connect the POSITIVE
side of the reference to pin 5, and the NEGATIVE (ground) to pin 6
on the 9 pin “D” connector.
b) When using the 4 to 20 mA reference signal, connect the POSITIVE
side of the reference to pin 7, and the NEGATIVE (ground) to pin 8
on the 9 pin “D” connector.
The NEGATIVE (ground) side of the reference signal inputs is
internally connected on the printed circuit board to power
ground.
b.1.3 TTL Signal Connection
The TTL valve ON/OFF control feature is not required for the device to func-
tion. Use of this SAFETY feature allows for complete de energizing of the
solenoid valve to help ensure valve closure. If this feature is not used, a
continuous supply of nominal power will be supplied to the solenoid valve.
When left unconnected on the 9 pin “D” connector, the device will default
to the “HIGH” setting in accordance with the selected position of the
jumper. The factory default setting is LOW (0 VDC) = OFF and HIGH (5
VDC) = ON.
