OTHER DEVICES CONTROL FINAL OUTLET PRESSURE.
NOTICE
The IntelliSwitch IIv™is not intended for use in medical
installations.
Basic safety precautions must be followed to reduce the risk of fire, electrical shock or injury.
Connect the IntelliSwitch IIv™to the correct line voltage. A label on the product
identifies what voltage it is wired for. CONNECTION TO AN INCORRECT
VOLTAGE CAN CAUSE SERIOUS DAMAGE TO THE PRODUCT AND WILL
VOID ANY WARRANTY.
Install the IntelliSwitch IIv™where the ambient temperature range is between 0° F and
140° F.
Do not install this product in a hazardous environment.
If product appears damaged in any way, do not use and request service from CONCOA.
Consult the cylinder distributor for the proper use of cylinders and for any restrictions on
their use (such as flow rate and temperature requirements).
Store cylinders with valve caps screwed on, and chain cylinders to a supporting wall or
column.
Handle cylinders carefully and only with valve caps screwed on. The cap will reduce the
chance that the cylinder valve will break off if the cylinder is accidentally dropped or
falls over. The cap also protects the cylinder valve from damage to screw threads, which
could cause leaky connections.
No smoking should be permitted near oxygen, nitrous oxide, any other oxidizer,
flammable gases, or flammable mixtures, or in areas where cylinders are stored.
Where an oxidizer (such as nitrous oxide or oxygen) is used, the manifold and cylinders
must be kept clean. No oil, grease, or combustible substances should come in contact
with oxygen or nitrous oxide storage or handling equipment. Such materials in contact
with oxygen or nitrous oxide are readily ignitable and, when ignited, will burn intensely.
Never lift gas cylinders with a magnetic lifting device.
Never use an open flame when leak testing.

2
Always open valves slowly when high-pressure gases are being used.
Always be sure that a cylinder contains the correct gas before connecting it to any
manifold.
Always leak-test any manifold or distribution pipeline before using.
Always be sure that the gas in a pipeline is the correct gas for the intended use.
Always close all cylinder valves before disconnectingcylinders from a manifold.
Always remove all empty cylinders from a manifold before connecting full cylinders.
Always test cylinders to be sure the cylinders are full before connecting to a manifold.

DESCRIPTION OF PRODUCT
The IntelliSwitch IIv™is a device used to monitor, control and switch the flow of gas from
cryogenic or high pressure cylinders from either of two independent sources, it does not control
the delivery pressure. The outlet pressure will be equal to the pressure in the side selected and
will vary or decrease as that source pressure varies or decreases in the case of high pressure
cylinder sources.
It consists of two electronically controlled inlet valves controlling the flow of gas into the outlet.
Pressure control must be adjusted from downstream regulator or device.
Pressure coming into the IntelliSwitch IIv™is monitored and displayed on two independent 4-
digit displays. The outlet pressure of the system is the same pressure as the pressure in the side
selected. When operating from the right side a “r” will be displayed on a 3-digit display when
operating from the left side a “L” will be displayed on the 3 digit display. When operating from
both sides in liquid cylinder service both a “r” and “L” will be displayed. Outlet pressure is
controlled by other devices.
A series of indicator lights show the status of the system at any given time.
The status of the IntelliSwitch IIv™may be monitored remotely via a serial port or optional
Ethernet port. In addition, the IntelliSwitch IIv™can interface with a CONCOA Remote Alarm.
FEATURES
Operation from Multiple Gas Sources
The IntelliSwitch IIv™is capable of operating with inlet pressure provided by 230, 350, and 500
PSI liquid cylinders, 3,000 PSI high pressure cylinders, or any combination. (4500 PSI option
Available). The 4500 PSI option may include or be ordered with right (5449999-01-001) or left
(5449999-01-002) pilot regulator and micro manifold kit. Please follow the instructions included
with the kits when installing.
Look Back
The IntelliSwitch IIv™switches from one bank to the other based upon the pressure supplied to
the selected bank. When using liquid cylinders, if the volume of the liquid in the cylinder
becomes low or the gas flow becomes particularly high, it is not uncommon for the pressure to
drop below the switching point even if there is plenty of gas left in the cylinder. When a typical
switchover enters such a state, two undesirable situations may occur. First, the system may switch
to the reserve temporarily until pressure builds on the primary enough to cause the system to
switch back. This situation often leads to depleting both sides at the same time as the system
rapidly alternates drawing from both sides or even draws both sides at the same time. Second, the
system may permanently switch to the reserve leaving unused product in the primary and
triggering a false alarm.
To avoid either of these situations, the IntelliSwitch IIv™has a Look Back feature that allows the
system to switch banks and wait a predetermined time period before checking the former primary
cylinder. If the pressure has recovered enough, the system will switch back to the former primary
cylinder. This look back time allows the pressure building circuit to recover and build sufficient
pressure to supply the system and fully draw down the primary cylinder before an alarm is
triggered indicating the cylinder is empty, allowing maximum utilization of cylinder contents. This
feature is only activated when a liquid cylinder is selected for use. The look back time is factory
set at 30 minutes.

5
Switchback Delay
Using the Look Back feature alone can result in the switchover switching back several times well
after the cylinder can provide a useful gas supply. To prevent this, the Switchback Delay feature
keeps track of how often the IntelliSwitch IIv™switches back to a liquid cylinder that has been
used and whose pressure has been restored to be used again.
If the system switches away from the priority side before the Switchback Delay timer has timed
out, the system determines that all the useful gas has been extracted from the cylinder and
switches to the auxiliary side and draws from it. This feature is only activated when a liquid
cylinder is selected for use. The switch back time is factory set at 10 minutes.
Hysteresis
This feature is a pressure value added to the switchover pressure value to determine the pressure
at which the IntelliSwitch IIv™will switch back to a cylinder after the “Look Back” time has
expired. This feature provides added protection against inadvertentlydrawing from the reserve
bank when the primary still has gas. The Hysteresis pressure is factory set at 10 PSI.
Economizer Function
When using liquid cylinders in switchover applications, it is common for the reserve cylinder to
build pressure due to the vaporization of liquid within the cylinder. When this pressure reaches
the set point of the relief valve on the liquid cylinder, the relief valve will open, venting gas to the
atmosphere. The IntelliSwitch IIv™constantly monitors the reserve cylinder and, at a
predetermined pressure, will change the valving to allow gas from the headspace of the reserve
cylinder to feed the system, thus drawing down the pressure in the reserve cylinder. There are three
pressure ratings for liquid cylinder relief valves, 230 PSIG, 350 PSIG and 500 PSIG; the
IntelliSwitch IIv™has predetermined settings for all three types that may be selected on the front
panel of the system.
Settable Switchover Pressure
The IntelliSwitch IIv™can be configured to switch at pressures ranging from 100 to 2000 PSI.
This value is factory set but can be changed in the field. To change this value, refer to the section
on changing the switchover pressure.
Manual Bank Switching
It is possible to manually change the side that gas is being drawn from by pressing the “BANK
SELECT” button provided that there is sufficient pressure on the side being switched to.
Selectable Units of Measure
The default units of measure for the IntelliSwitch IIv™are PSI. Alternate units of BAR or MPA
can be selected by changing internal DIP switch settings. To change units of measure refer to the
section on changing units of measure.
Security Lockout
The IntelliSwitch IIv™has the ability to electronically lockout the front panel buttons
to
discourage tampering. The factory default setting is OFF or disabled. Refer to section on Keypad
Security Lockout for details.

6
Alarm Notification
The IntelliSwitch IIv™is designed to interface with CONCOA Remote Alarms and comes with
the necessary mating connector for their use. Refer to the section on connecting a remote alarm
for more information.
Ethernet Port –Web Server
The IntelliSwitch IIv™is equipped with an integral Web Server allowing for remote monitoring of
functions, e-mailing, and remote configuration. For more information on the Web Server feature
refer to the Web Server manual included with this product.
Serial Port
The IntelliSwitch IIv™is capable of communicatingto peripheral equipment via
configurable
serial port. For more information on the serial port refer to the section on Setting Communication
Mode in this manual.
High Flow Relief Valve Overpressure Protection
The IntelliSwitch IIv™is equipped with a high flow relief valve to protect the system from
extreme pressure increases and liquid withdrawal. The IntelliSwitch IIv™ does not control
outlet pressure. Pipeline or systems connected to the IntelliSwitch IIv™ must be rated for
the maximum inlet pressure to the system.

7
INSTALLING THE INTELLISWITCH IIv™
Understanding the application and sizing the components properly is the key to
any successful system installation.
Figure 1 shows a typical installation.
Figure 1
The inlets and outlet on the IntelliSwitch II™ are 1/2” Female NPT fittings. It is strongly
recommended that two wrenches be used when tightening external devices to these fittings.
The IntelliSwitch II™ uses four mounting tabs for mounting to a wall or panel. Refer to Figure 14
at the back of this manual for the dimensions of the system. Anchor the IntelliSwitch II™
securely to a wall or panel at a height adequate to conveniently connect a manifold or pigtail.
THE HEIGHT SELECTED MUST MEET ALL REGULATORY REQUIREMENTS
Once all mechanical connections are made pressurize the system and check for leaks.
Connect the Remote Alarm and serial device (if used) to the IntelliSwitch II™.
Finally connect AC power to the IntelliSwitch IIv™. The system is factory set to operate at either
115VAC 60hz or 230 VAC 60hz. Check the product label for the product voltage. Connection
of the IntelliSwitch II™ to the incorrect input voltage will damage the product and void any
warranty.

8
CONNECTING POWER
THERE IS NO ON/OFF POWER SWITCH FOR THE INTELLISWITCH IIv. The installer must
provide any required power switching external to the product. Please ensure that wire is no longer
than 5cm from the penetration of the enclosure to the EMI filter inside the box.
The inlet pressure readings will appear on the two 4-digit displays. If necessary use the Bank Select
pushbutton to choose the side considered to be the primary gas source. The IntelliSwitch IIv™ will
default to the left inlet side as the primary side.
Normal operation of the IntelliSwitch IIv™ can now begin. The “primary” or “active” inlet side of
the system, whether left or right, will have the green Ready light ON and the In-Use light ON over
the source pressure. The “secondary” side or the “in-active” side will have only the green Ready
light ON.
Lighted green lights above the Source Select buttons should match the types of cylinders being used
by each side.
All switching is automatic. If the primary inlet gas side drops below the set switchover point, the
system will transfer to the reserve inlet gas side and the status lights will indicate the transition. The
Replace status light and alarm indicate the need to replenish a bank. In the case of high pressure
cylinders, the system will reset when pressure has been restored to the depleted bank. In the case of
liquid cylinders, the system will reset when pressure has been restored to the depleted bank and the
Reset button has been depressed.

OPERATING THE INTELLISWITCH IIv™
Figures 3 & 4 identify the various locations of important features on the IntelliSwitch IIv™.
Delivery Pressure
Delivery Pressure is not controlled by the 544 series IntelliSwitch IIv the side selected as the
supply side will deliver it’s inlet pressure to the outlet of the IntelliSwitch IIv. A separate
downstream regulator or control device is used to set the pipeline or system delivery pressure.
All components from the outlet of the 544 IIv to that device must be suitable to handle the
maximum inlet pressure expected from the sources connected to the system. The source of the
outlet pressure will be displayed in the center LED display. (See Figure 3).
Selecting a Gas Source
The Source Select buttons on the front panel provide flexibility in the choices of liquid or high
pressure cylinders used in an application. Further, they provide choices of liquid cylinders with
different pressure ratings. There are two Source Select buttons, allowing each side to be controlled
independently. Green indicator lights directly above the Source Select buttons identify which
cylinder choice is currently selected for the side. Each time a Source Select Button is pressed, the
indicator lights above the button will shift to the next choice.
Cylinder Sizes
There are three liquid cylinder pressure ratings that can be selected. For each cylinder pressure,
the IntelliSwitch IIv™has a preset value it uses to determine when the cylinder has reached an
overpressure condition in order to activate the economizer feature. Table 1 provides the cylinder
pressure choices and their respective economizer pressures.
Table 1

325 PSI
300 PSI
500 PSI
475 PSI
450 PSI
If a liquid cylinder’s pressure rises to the “activation” pressure, the IntelliSwitch IIv™will redirect
itself to draw the pressure down through the delivery stream. Once the pressure reaches a “normal”
value, it will return to drawing from the previous side.
Bank Selection
The Bank Select button on the front panel allows for manually switching the active bank. The In-
Use status indicator lights provide the feedback to indicate which side is selected. The outlet
pressure will equal the pressure in the bank that is selected and will display that as “r” for right
bank and “L” for left bank on the outlet pressure display.
Reset
The Reset button is primarily used to reset a “replace” condition when using liquid cylinders. The
Replace status light can only be cleared if the side with the condition has its pressure restored to a
value above the switchover (trip point) plus the Hysteresis value AND the Reset button is pushed.
If the button is pushed while the condition still occurs, the system will attempt to clear the
condition but will reinstate the indicators automatically. Example: Switchover(trip point) = 200
PSI. System will switch to the other side when pressure drops to 130 PSI. It will not allow
switching back until the pressure reaches 210 PSI (200 PSI + 10 PSI Hysteresis pressure)

10
Testing
Holding the Reset button in for 5 seconds will place the system in test mode. This diagnostic and
troubleshootingtool performs 16 different tests. Each time the Reset button is pushed again, the
system will perform a different test. Continuing to press the Reset button will step through all the
tests after which the system will return to normal operation. If after the test mode has been
entered there is no pushbutton activity for 5 minutes, the system will return to the normal display
operation. Gas flow is maintained during the test mode. Refer to the TroubleshootingSection for
details on testing.
Keypad Lockout
If the keypad security lockout feature is enabled, the keypad will become inoperative after
approximately 5 minutes provided there has been no buttons pressed. There will be an audible
beep when the keypad goes into the locked state. If the keypad becomes locked it can be re-
activated by holding the Bank Select Pushbutton for approximately 4 seconds. The system will
make an audible beep when it is unlocked. To enable this feature, see Section “User Selectable
Features” for explanation on enabling/disablingthis feature.
