Check immediately to establish whether damage has occurred to the external packaging and if the damage extends to the
product inside. If there is damage to a product, contact the relevant supplier immediately.
Under no circumstances must a damaged product be used in operation. Using damaged products can lead to
irreparable functional faults or cause serious physical harm.
1.6 general safety
No modications must be made to the product. Any modications may reduce the operational safety of the product and
invalidate the manufacturer’s warranty. This could potentially result in damage to the product and serious personal injury.
For your own safety, when carrying out work on this product, all relevant national safety regulations must be
complied with relating to pressurized and electrical systems.
1.7 intended use of the product
The nitrogen generator is exclusively intended for the production of nitrogen gas from compressed air, which is free from
bulk water, oil and solid matter constituents and contaminants.
The product should be located within a building and protected from extreme conditions and weather. The nitrogen generator
must be operated only in accordance with the data on the rating plate. Any operations that do not comply with those stated
on the product rating label will render the warranty void.
This product is designed to operate at a maximum operating pressures of between 6 to 12 barg (87 to 174 psig).
It is not suitable for pressures in excess of 12 barg (174 psig) although a higher pressure system is available
upon request.

1.8 safe handling
Please ensure the relevant safe engineering practices and handling procedures are employed when handling, installing and
operating this product. Ensure that the equipment is depressurized and electrically isolated prior to carrying out any of the
scheduled maintenance instructions specied within this user guide.
A suitable lifting aid must be used to minimize the risk of physical injury or damage to the product.
1.9 technical description
The nitrogen generator operates on the Pressure Swing Adsorption (PSA) principle to produce a continuous stream of
nitrogen gas from clean dry compressed air.
Pairs of dual chamber extruded aluminum columns, lled with Carbon Molecular Sieve (CMS), are joined via an upper and
lower manifold to produce a two bed system. Compressed air enters the bottom of the ‘online’ bed and ows up through the
CMS. Oxygen is preferentially adsorbed by the CMS, allowing nitrogen to pass through.
After a pre-set time the control system automatically switches the bed to equalization mode where the online bed pressure
is equalized with the second regenerated bed. Once equalized the online bed is switched to regenerative mode and oxygen
is vented from the CMS. A small portion of the outlet nitrogen gas is expanded into the bed to accelerate the regeneration.
At the same instant the second bed comes on-line and takes over the separation process.
The CMS beds alternate between online equalization and regeneration modes to ensure continuous and uninterrupted
nitrogen production.
The oxygen concentration in the nitrogen stream is monitored continuously on models tted with an oxygen analyzer. If the
outlet concentration exceeds the required production level, the nitrogen outlet is closed and the gas is vented to atmosphere.
Normal operation will resume when the purity recovers. Various options are available for the nitrogen generator, please
contact your supplier for more information.

Only personnel trained, qualied and approved by the supplier should perform installation, commissioning,
service and repair procedures.
It is essential that the system into which the product is installed is tted with a pressure limiting/relief device.
This device should be between the compressor and the generator. The device must be set to prevent the
maximum working pressure of 12 barg (174 psig) or 16 barg (232 psig) from being exceeded.

12
nitrogen gas generator
2.6 site location and installation
When selecting an installation site for the generator , ensure the following conditions are met:
• The site should be located indoors on a at surface protected from weather and other harmful conditions.
• The ambient temperature must not drop below 5°C (41°F) or exceed 50°C (122°F).
• The installation site should be level and able to support the weight of the product.
• Ensure sufcient space around the product, we recommend at least 1m around the generator to allow access for
operation and maintenance.
• Take into account the noise generated when in use when considering the nal location.
Due to the nature of operation there is a possibility of oxygen enrichment surrounding the generator. Ensure the
area surrounding the generator is adequately ventilated.
Once the generator has been located into position, install ball valves and the pipework ready for connection to the buffer
vessel and compressed air supply. The diameter of the pipes must be sufcient to allow unrestricted inlet air supply to the
generator and nitrogen supply to the applications. Ensure that all piping materials are suitable for the application, clean and
debris free. All outlet piping must be solid and non-porous to minimize the ingress of oxygen. When routing the pipes ensure
that they are adequately supported to prevent unnecessary strain which can lead to damage and leaks in the system. The
nitrogen buffer vessel must be rated to at least the maximum operating pressure of the system and must be tted with a
suitable drain valve, pressure gauge and pressure relief valve.

2.7 electrical installation
Once in position, locate and remove the IEC plug from the side of the generator enclosure. Remove the back of the IEC
plug and wire in your desired cable using the diagram below, we recommend using at least 0.75mm2 (20AWG) gauge
cable although this will vary depending on the cable run length. Each C13 IEC plug is rated to 10A / 250V AC and can
accommodate a cable size of up to 1.00mm2 (18AWG) .
IMPORTANT: This product must be grounded. In the event of an electrical short circuit, grounding reduces
the risk of electric shock by providing an escape wire for the electric current. This product is equipped with
a plug with an appropriate grounding post. The plug must be plugged into an outlet that is properly installed
and grounded in accordance with all local codes and ordinances. Check with a qualied electrician or service
representative when the grounding instructions are not completely understood, or when in doubt as to whether
the product is properly grounded. Do not modify the plug provided; if it does not t the outlet, have the proper
outlet installed by a qualied electrician.

2.8 remote start/stop control
To use the remote start/stop feature, open the enclosure and locate the wire link marked as ‘RS’ on the PLC (see item
No.1 for reference). Remove the wire link from terminal i0 and move it across to redundant terminal i6 (see item No. 2 for
reference).
In order to control the generator remotely via the start/stop feature you are required to install an additional two connections.
First, an additional wire connection is required into the terminal ‘24V DC output’ (see item No.3 for reference) this must be
wired externally to the input of a switch or relay. Once this connection has been made you will need to add an additional
connection on the output of the switch or relay, this should then be wired back to the PLC into terminal i0 (see item No.4 for
reference).
When the connection is made and the circuit is complete you can then start the generator using the HMI power ON button.
If for any reason this wired connection is broken, i.e. the generator has been remotely switched off, the generator will
automatically commence a shut down procedure, stop cycling and go into standby mode until the connection is reestablished.
Under no circumstances should an external voltage or current be applied to any of these terminals, as damage
to the control system will occur, negating the warranty.

15
nitrogen gas generator
2.9 remote alarms and dryer control
Every nitrogen generator comes with three remote alarms as standard. In order to use the remote alarms, you are required to
install an additional four wired connections. First, you must install a wired connection into terminal ‘COM3’ (see item No.1
for reference) this will be the voltage that is then relayed back to your equipment. The relay outputs are capable of switching
any voltage from 5V to 277V AC / 125V DC and a maximum current of 7Amps. Next you will need to add an additional three
connections on each relay, terminal Q12, Q13 & Q14. (see item No.2, 3, 4 and 5 for reference). Each relay output relates to
a different alarm code;
• (1) Terminal COM3 - 5...277V AC / 125V DC, 50/60Hz, Max 7A
• (2) Terminal Q12 - Alarm output 1: Low inlet pressure alarm
• (3) Terminal Q13 - Alarm output 2: Low outlet pressure alarm
• (4) Terminal Q14 - Alarm output 3: High oxygen purity alarm
• (5) Terminal Q15 - Alarm output 4: Dryer Contact
When making wired connections to and from the generator, there are six M16 cable gland knockouts located
under the mains input socket. Using a blunt object, knock out the metal discs and insert M16 cable gland(s),
these can then be numbered or marked up accordingly.

3.1 user interface quick reference
If you require further details of the user interface, contact your service provider for the additional operators
manual.
After 10 minutes of inactivity, the generators HMI will enter an energy saving mode where the HMI screen will
go black. A green LED will remain lit at all times to indicate the HMI is still fully functional. If at any point the
HMI detects human interaction the energy saving mode will deactivate and the screen will revert back to the
mains display seen above.

• Switch on the power to the generator, the control system will carry out an initialization procedure.
• Slowly open the compressed air inlet isolation valve until fully open and check for leaks.
• Locate the ‘START’ button in the bottom right of the HMI screen and hold down for 3 seconds, the generator will begin
it’s start-up procedure.
• Once the generator has completed its start-up procedure the compressed air inlet symbol will turn from amber to blue,
at this point slowly open the inlet isolation valve of the buffer vessel.
• Once the buffer vessel is within 0.5 barg (7.2 psig) of the compressed air inlet pressure, slowly open the outlet isolation
valve of the buffer vessel until fully open. Check all connections to and from the buffer vessel for any leaks as this could
affect nitrogen purity.
• Slowly open the nitrogen outlet isolation valve until fully open.
• If the generator is working correctly, the nitrogen outlet button and O2 symbol will turn green to show the purity is within
specication and the generator is producing gas. If the generator develops a fault it will raise an alarm and indicate what
has caused the alarm by turning the relevant symbol red.
3.3 shutdown procedure
• Fully close the nitrogen outlet isolation valve.
• Locate the ‘STOP’ button in the bottom right of the HMI screen and hold down for 3 seconds, the generator will begin it’s
shutdown procedure. At this point the generator will complete it’s half cycle and then exhaust both columns until fully
de-pressurized.
• The generator will remain in standby until manually re-started. When the generator is in standby mode all symbols will
revert to their grey color to symbolize no activity within the system.

3.4 economy mode
When under normal operation, the generator continuously monitors the nitrogen outlet pressure. When the outlet pressure
reaches the pre-determined set-point for 5 minutes, the generator will automatically close the nitrogen outlet valve and stop
supplying gas. This rst stage is indicated by the solid green economy symbol. If the outlet pressure continues to remain
equal to or greater than the pre-determined set-point for an additional 5 minutes, the generator will stop cycling and enter
economy mode. This second stage is indicated by the ashing green economy symbol.
When the nitrogen outlet pressure drops below the pre-determined set-point, the generator will instantly begin it’s start-up
cycle to ensure the CMS is primed before resuming normal operation.
3.5 purity dependent energy saving (PDES)
When tted, the PDES system adds an additional O2 analyzer assembly which constantly monitors the oxygen content of the
gas stored within the buffer vessel, the purpose of the PDES system is to reduce air consumption and maximize efciency.
The PDES system works along side with the standard O2 analyzer which monitors the purity of the gas being produced and
supplied to the application. Under normal operation, if the oxygen content stored within the buffer vessel and the gas being
supplied to the application are within specication, the generator control system will extend the cycle time delaying the
column change over. When the PDES function is active the green O2 symbol will begin to ash indicating the generator is
extending the cycle time.
If at any point either the gas stored within the buffer vessel or the gas being supplied to the application falls outside of the
required specication, the PDES feature will deactivate and the generator will resume normal operation.

4.1 maintenance
Maintenance operations should only be conducted once the system has been shut down and is fully
depressurized. All operations should be carried out by authorized and suitably trained personnel.
• Isolate the generator from the compressed air and electrical supply ensuring the system is in a safe condition for
maintenance to be carried out.
• All connections must be removed with care, paying particular attention to the areas that become pressurized.
• All seals removed during maintenance operations must be replaced with new seals.
• Only certied and approved replacement parts should be used.
• Do not modify or adjust the control settings.
• Check all connections and sealing faces for cleanliness and secure seating prior to assembly.
• Ensure all components are re-tted to the product before operation.
• Check all connection and sealing faces for any leakage, if any found resolve and check again.
• Ensure the generator is left operating in a safe working condition after completion of maintenance.
4.2 cleaning
Clean the equipment with a damp cloth only and avoid excessive moisture around any electrical connections. If required a
mild detergent can be used. Do not use abrasives/solvents as these may cause damage.
4.3 daily checks
• Check the generator for any signs of external damage.
• If the red service indicator is active, the generator must be serviced to ensure continued operation.
• Remove any loose dust or dirt from the generator, clean all surfaces that appear to have attracted unwanted contaminants.
• Ensure the generator is operating within the purity specication.
• Always check all connections for any leaks.
• Ensure all loose parts are removed or secured to the generator before operation.
