 Important notes:

In general, "D" Connector numbering patterns are standardized. There
are, however, some connectors with nonconforming patterns and the
numbering sequence on your mating connector may or may not coincide
with the numbering sequence shown in our pin configuration table above.
It is imperative that you match the appropriate wires in accordance with
the correct sequence regardless of the particular numbers displayed on
your mating connector.

Make sure power is OFF when connecting or disconnecting any cables
in the system.

The power input is protected by a 1600mA M (medium time lag) reset­table fuse. If a shor ting condition or polarity reversal occurs, the fuse will
cut power to the valve driver circuit. Disconnect the power to the unit,
remove the faulty condition, and reconnect the power.The fuse will reset
once the faulty condition has been removed.

Use of the FSV10 valve driver in a manner other than that specified in this
manual or in writing from Omega, may impair the protection provided by
the equipment.

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 pro­vided.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.

For optional RS232 or IEEE488 interfaces please contact Omega.

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 v alve ON/OFF control f eature is not required for the de vice to func­tion. 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.

Jumper Setting (position) TTL LOW (0 VDC) TTL HIGH (5 VDC)

4 OFF ON
5 ON OFF

Table I TTL Signal Selection

To reverse this configuration, remove the square cap on the back of the
FSV10 (see Figure e-1). The 4th and 5th position determines the TTL
logic configuration. The factory default setting is set with the jumper on
position 4. Moving this jumper to position 5 will yield the reverse configu­ration [LOW (0 VDC) = ON and HIGH (5 VDC) = OFF] (see Table I).

Always make sure that only one jumper is ever applied at any
given time to either position 4 or 5. Connecting both at the same



time may result in damage to the electronics, and improper control.

b.1.4 Power Connection

With the DC power supply source OFF, connect the power to the DC
power jack OR the 9 pin "D" connector.

DO NOT CONNECT POWER TO BOTH CONNECTION POINTS
AT THE SAME TIME.This may result in permanent damage to



the power supplies and the FSV10.

(c) DESCRIPTION

The FSV10 solenoid driver module is designed to regulate the power
supplied to the proportional solenoid valve based on a reference signal.
A 0 to 5 VDC or 4 to 20 mA analog set point signal input is used as a ref­erence to proportionally control the output power to the valve.By increas­ing or decreasing this analog reference signal, the valve volume of gases
or liquids processed increases or decreases respectively.

(d) SPECIFICATIONS
Environmental (per IEC 664): Installation Level II; Pollution Degree II.
Connection: 9 pin male "D" connector for input/output signals.
Power Input: +12 to 30 VDC; 1A @ 12 VDC, 0.5A @ 24 VDC via 9 pin

"D" connector or DC power jack (center positive).
Input Signal: AUTO SELECT feature allows circuit to recognize which

analog input reference (0 to 5 VDC or 4 to 20 mA) signal is received.

For optional RS232 or IEEE488 interfaces please contact Omega.

TTL ON/OFF: Jumper selectable LO W (0 VDC) OFF - HIGH (5 VDC) ON
[default setting] or reverse, to select valve ON/OFF status.

e.1 Preparation

It is assumed that the FSV10 has been correctly installed as described in
section (b).Turn the DC power source ON. A pilot light on the front of the
FSV10 will illuminate indicating the device is active.

e.2 Maximum Output Voltage to Valve

As shown in Figure e-1, remove the square plug of the FSV10 for the
access window. Position 1, 2, and 3 on the header block deter mine the
maximum output voltage supplied to the valve. The factory default setting
is 22 VDC (position 2).

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 operat­ing 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 per­formed. It is provided as an added feature to fur ther customize your sys­tem.) 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 ref­erence 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 con­figuration is set so that when 0 VDC (LOW) signal is applied, the solenoid
valve is not pow ered and theref ore 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)

6

Toggling the HIGH/LOW signal on and off will allow for activating and
deactivating the solenoid valve. Remember: If the TTL signal line is con­nected, the valve will only function if the appropriate logic input is applied.

e.5.1 FSV Preperation and Operation

Prior to connecting gas/liquid flow lines inspect all parts of the piping sys­tem including ferrules and fittings for dust or other contaminants. Be sure
to observe the direction of flow as indicated by the arrow on the front of
the valve when connecting the fluid flow system to be monitored.

Insert tubing into the compression fittings until the ends of the properly
sized tubing home flush against the shoulders of the fittings. Compression
fittings are to be tightened according to the manufacturer's instructions to
one and one quarter turns. Avoid over tightening.

Once installed inline with the gas or liquid to be controlled, apply a vari­able DC power source at the two solenoid wires to proportionally open
and close the solenoid valve (there is no polarity). The valve is set to
begin opening at approximately 5 VDC. They can also serve as "on off"
valves (valves are not guaranteed for absolute closure). Optional FSV D
DRIVER MODULE is available when use of a 0 to 5 VDC or 4 to 20 mA
reference control signal is desired. Contact Omega7 for more information.

FSV Proportionating Solenoid Valves are uniquely designed to respond
to variable power inputs (0-30 VDC) to regulate flow of liquids and/or
gases proportionately. For added safety FSV valves are normally closed
(NC) when de-energized.

 Flow equipment should not be used for monitoring OXYGEN unless specifically cleaned and

prepared for such application. For more information, contact Omega7.

 If the valve is left in the active mode for an extended period of time, it may become warm or

even hot to the touch. Use care in avoiding direct contact with the valve during operation.

 To protect servicing personnel it is mandatory that any instrument being serviced is completely

purged and neutralized of toxic, bacteriologically infected, corrosive or radioactive contents.

 Use of the FSV valve in a manner other than that specified in this instruction sheet, may impair

the protection provided by the equipment.

e.5.2 FSV Maintenance

The solenoid valve consists of 316 and 416 stainless steel, and VITON7
(or optional BUNA-N7, NEOPRENE7 or KALREZ7) O-rings and seals.No
regular maintenance is required except for periodic cleaning.Various cor­rosive gases or liquids may demand more frequent replacement of O­rings and seals inside the valve. Be sure to use an elastomer material,
appropriate for your specific application. Contact Omega7 for optional
sealing materials available.

Set the FSV for maximum flow, and attempt to flush through in both direc­tions with a clean, filtered, and neutral gas such as nitrogen. [Another
option for fully opening the valv e is to remo ve the plastic cap on top of the
valve, and turn the set screw counterclockwise until it stops]. If blockage
is not alleviated, return the unit to Omega7 for servicing.
