Table II Maximum Valve Output Selection
The maximum output voltage supplied to the valve, can be set/changed
in the field. Changing this will allow for optimal use of the input reference
signal to output valve voltage based on the specific flow rate and operat-
ing pressure applied to the valve.
With the power ON, use Table II and Figure e-1 to make the appropriate
changes as necessary. (Note: This procedure may not need to be per-
formed. It is provided as an added feature to further customize your sys-
tem.) Move the jumper to either position 1, 2, or 3, and use the adjacent
potentiometer [P1] to make fine adjustments to the desired output voltage.
Always make sure that only one jumper is ever applied at any
given time to either position 1, 2, or 3. Connecting two or more
at the same time may result in damage to the electronics, and
improper control.
e.3 Set Point Reference Signal
The FSV10 solenoid valve driver in conjunction with the solenoid valve
allow the user to set the flow to any desired flow rate within the range of
the particular model installed. The solenoid valve is normally closed when
no power is applied.
The set point input responds to an analog 0 to 5 VDC or 4 to 20 mA ref-
erence signal. Use this reference signal via the FSV10 valve driver to set
the flow rate of the solenoid valve.
e.4 TTL, Valve ON/OFF Control
It may, at times, be desirable to set the flow and maintain that setting while
being able to turn the flow control valve off and on again. This can be
accomplished by applying a (TTL compatible) high and low signal of +5
VDC and 0 VDC to pin 9 on the 9 pin “D” connector. The factory default con-
figuration is set so that when 0 VDC (LOW) signal is applied, the solenoid
valve is not powered and therefore will remain normally closed. Conversely,
a +5 VDC (HIGH) signal applied will allow the solenoid valve to remain
active. The solenoid valve will remain active when the VALVE OFF pin
remains “floating”. (To reverse this configuration, see section b.1.3)
