1.6 Specific safety precautions for oxygen generating equipment

Oxygen generators can be installed in the vicinity of the oxygen consuming application without the
requirement for classification of the surrounding area as hazardous, provided that all necessary measures have
been taken to guarantee the maximum safety.
The oxygen generating unit must be installed and used in observance of the instructions in this booklet. Failure
to observe these instructions will render the guarantee null and void and release the manufacturer from all
liability for direct or indirect damage or physical injury.
Hoses, pipes and connections used must be of the correct size and must be suitable for the working pressure.
Never use frayed, damaged or worn hoses. Connections made to the equipment must be free of strain.

Oxygen is a very corrosive medium.

When installing an oxygen net, make sure that all pipes, tubes, hoses, fittings and eventual
instrumentation are cleaned and suited for oxygen service. High velocities of oxygen in
combination with inappropriate materials and oil, dust or other debris might cause ignition
in the oxygen net. Suited materials for an oxygen net are copper pipes, stainless steel
pipes or nylon tubes.
Aluminium pipes are to be avoided.

When performing maintenance on pneumatic valves that come in contact with oxygen,
make sure the valves are greased with oxygen approved grease (such as
Paraliq_GTE_703) or lubricants.
Do not use regular grease, lubricants or oil, as these can self-ignite or even explode when
in contact with oxygen.

Normal oxygen concentration in air is approximately 21% by volume. In general, air containing less than
19.5% or more than 23.5% oxygen constitutes a hazardous working environment. Typical symptoms of
oxygen deficient atmospheres are listed in the table below. (ref. ANSI Z88.2)

% Oxygen at sea level (Atmospheric pressure) Effects

>23.5 Increased fire hazard
20.9 Normal
19.0 Some adverse physiological effects occur, but they
are unnoticeable.
16.0 Increased pulse and breathing rate. Impaired thinking
and attention. Reduced coordination.
14.0 Abnormal fatigue upon exertion. Emotional upset.
Faulty coordination. Poor judgment.
12.5 Very poor judgment and coordination. Impaired
respiration that may cause permanent heart damage.
Nausea and vomiting.
<10 Inability to perform various movements. Loss of
consciousness. Convulsions. Death.

Oxygen concentrations higher than 23.5% create greater fire hazards than normal air. Oxygen is not
combustible, but it promotes very rapid combustion of flammable materials and some materials that are
normally regarded as being relatively non-flammable.

8 2920 7120 40
Instruction book

Although a source of ignition energy is always necessary in combination with flammable materials and
oxygen, control or elimination of flammables is a precautionary step.
In the direct vicinity of the generator, nitrogen enriched air (only 8 - 10 % oxygen) is vented through the
muffler during the separation process. When the percentage of the vented nitrogen in the air exceeds a specific
value, there is a risk of asphyxia, unconsciousness and death. Therefore, never direct inhale the vented gas,
and avoid working in the immediate vicinity of the generator when it is in use.
In normally ventilated areas the nitrogen concentration decreases quickly to the normal concentration in air
at short distance from the vent pipe. If required, the muffler should be vented to the outside or to another room
with proper venting. Consult your supplier if in doubt.
More details about the characteristics of nitrogen or oxygen can be found in the safety datasheet for nitrogen
and oxygen, both available as a separate publication (consult your supplier).
Areas where it is possible to have an oxygen enriched or deficient atmosphere should be well ventilated. If
required, warning signs should be posted and special precautions shall be taken such as installing analyzers
with alarms, ensuring a minimum number of air changes per hours, implementing special entry procedures
or a combination of these.

The oxygen generators described in this book are suited for industrial use.
When the generator is to be used for medical purposes the installation has to comply to
the locally applicable medical legislation.

When oxygen should be vented, it has to be guided outside to atmosphere. Make sure the
vent pipe is properly labelled and warning signs indicate the risks. No open flame or
smoking are allowed in the vicinity of oxygen vents.

1.7 Safety labelling on oxygen generators

The following safety label is attached to the oxygen generators:

2920 7120 40 9
 Instruction book

Safety label 1629 0901 38

Oxygen is a colourless, odourless, tasteless and oxidizing gas. Oxygen enriched air leads
to an increased risk of fire in the event of contact with inflammable products.
Nitrogen enriched air is released as waste. Nitrogen gas is colourless, odourless and
tasteless, and does not support respiration. Nitrogen can cause suffocation. Make sure
that there is adequate ventilation at all times.

2 Description

2.1 General description

Working principle
OGP 2 up to OGP 200 oxygen generators are intended to produce oxygen (O2) for industrial purposes. They
use Pressure Swing Adsorption (PSA) technology to produce oxygen by passing compressed air through a
tank containing adsorbent material.
The adsorbents are chosen on the basis of their adsorption characteristics: the adsorbent has much more affinity
for non-product molecules than for the product gas (O2). This characteristic results in most of the desired
molecules (O2) passing through the bed and remaining in the product stream, while undesired components
(product impurities) are captured by the adsorbent.
The PSA process is inherently a batch process, as the adsorbent bed requires periodic desorption.
Consequently, PSA systems usually contain two adsorbent tanks to provide operational continuity. At any
time, one of the tanks will be delivering product (O2) by adsorbing undesired components of the air, while
the other tank is being regenerated by depressurization to atmospheric pressure. When the adsorbing tank
approaches saturation, a set of valves quickly switches the functions. A buffer tank downstream of the oxygen
generator ensures that the delivery of oxygen is continuous.
During the adsorption phase, compressed air flows through the sieve material and nitrogen molecules are
caught, while oxygen molecules pass on due to the different molecular size. The material continues to adsorb
nitrogen until a saturation point is reached. During desorption, the entering air stream is cut off and the nitrogen
is able to leave the tank at low pressure.

Operating principle of the oxygen generator

Oxygen PSA tanks contain Molecular Sieve (MS) material to remove the nitrogen and other undesired
components from the compressed air.

12 2920 7120 40
Instruction book

The generator produces oxygen at a purity level between 90 % and 95 % according to the user requirements
and the required oxygen flow and pressure.
The oxygen flow rate depends on the model and the required purity.
The oxygen pressure depends on the pressure of the compressed air at the inlet.

2.2 Detailed description

The oxygen generator is controlled by an Elektronikon® Graphic controller.
This controller is integrated in a cubicle at the front.
Other electric components like fuses, transformers, etc. are located inside the cubicle.

3.2 Installation

Outdoor operation
• If the generator is installed outdoors or if the ambient or air inlet temperature can be below 5 ˚C (41 ˚F),
precautions must be taken. In this case, consult Atlas Copco.

38 2920 7120 40
Instruction book

• Humidity and dust: to avoid risk of damage to the electronic components, install the generator in an
environment subject to limited relative humidity and low concentration of dust. The generator must also
be protected against water droplets, rain and wind. According to the Low Voltage requirements
(EN61010), indoor use is recommended for this unit.

Installation area requirements

Oxygen is an oxidizing agent. Take extra care for cleanliness when assembling the oxygen
piping. Keep the installation away of flammables and heat sources.

• Temperature: the ambient temperature in the generator installation area must be between 5 ˚C (41 ˚F) and
45 ˚C (113 ˚F). Install the generator away from heat sources. Therefore, also avoid direct exposure to
sunlight.
• Positioning: when selecting the installation area for the generator, take into account minimum clearances
required for operation and maintenance. Consult the Installation proposal drawings further in this chapter.
Install the generator on a level floor, suitable for taking its weight.

Handling and positioning of the oxygen generator

The generator must be handled using suitable equipment such as a pallet mover or a forklift truck.
Remove all packaging, taking care not to damage the generator.

Keep the generator in vertical position at all times. It is not designed to be laid on its side
(even not during transport !).

Inlet air quality

The properties of the compressed air at the inlet of the oxygen generator, as well as the
minimum pressure and flow rate requirements, play an important role with regard to its
performance and lifetime.
The compressed air used should be of a quality that meets ISO 8573-1; class 1-4-1. Using
a lower quality of compressed air will cause irreversible damage to the generator. In such
case, the manufacturer denies all liability for damages and any costs for repairs will be
charged to the client.
The purity of the oxygen produced is reduced when the air pressure at the inlet decreases.
Therefore the installation of an accordingly sized compressed air tank is recommended.
In case of any doubt with regard to the above, contact your supplier for advice on the most
suitable compressed air system (compressor, dryer, filters, tank) for the specific
application.

The inlet dew point should be kept at 3 °C and not exceed 5 °C (at reference conditions). This dew point can
be established by a correctly sized refrigerant dryer. In case of high ambient temperatures, an oversized
external refrigerant dryer should be selected.
The oxygen generators can be used with oil injected compressors as well as with oil free compressors.
Please note however that it is of utmost importance to prevent any dust, water or oil from entering the
oxygen generator, because this will damage the molecular sieve material. Contact Atlas Copco for
advice in case of doubt.

2920 7120 40 39
 Instruction book

• If an oil injected compressor is used, a complete filtration package (DD, PD, QDT,- see installation
proposal drawings) is to be installed upstream the compressed air tank, just after the compressor
outlet.
On DD and PD inlet filters, a drain tube must be installed. The drain pipes to the drain collector must not
dip into the water. For draining of pure water when oil injected compressors are used, install an oil/water
separator (consult Atlas Copco).
• If an oil free compressor is used, principally no filter is required at the generator inlet, but specific
applications may require an oxygen approved filter downstream the oxygen tank, e.g. to protect the
application from eventual dust contamination.
• If the compressor is not equipped with an automatic water separator, install an automatic water separator
upstream the inlet filters.

Piping connections
The illustration shows the components used in a typical oxygen generator system.
Avoid distances exceeding 2 m (6.5 ft) between the various elements.

Oxygen is a very corrosive medium.

When installing an oxygen net, make sure that all pipes, tubes, hoses, fittings and eventual
instrumentation are cleaned and suited for oxygen service. High velocities of oxygen in
combination with inappropriate materials and oil, dust or other debris might cause ignition
in the oxygen net. Suited materials for an oxygen net are copper pipes, stainless steel
pipes or nylon tubes. For more detailed information on oxygen pipe systems refer to
instruction 9828 0757 00. Aluminium pipes are to be avoided.
All piping is to be connected stress-free.

• Connection of the inlet:

• Locate the air coupling, on the inlet pressure regulator (RV01), at the front side of the generator.
• Connect the hose or the flanged pipe.
• Connect the other end of the hose to the compressed air tank (upper coupling).
• Connection of the oxygen tank
Connect the oxygen outlet of the generator to the oxygen tank (TK04).
• Connection of the oxygen sensor
Connect the oxygen feedback line (SL01) from the oxygen tank (TK04) to the oxygen sensor (GA01).

Instruction book

• Oxygen outlet
The generator produces oxygen at a preset purity level (between 90 % and 95 %) according to the user's
requirements and required oxygen flow and pressure.
The oxygen flow rate depends on the model and on the required purity.
The oxygen pressure depends on the pressure of the compressed air at the inlet.

If the application involves metal cutting, welding, brazing, etc. it is highly recommended to
use flash guard check valves as close to the torch head as possible.

• Connection of safety valves to outside

The safety valves on the adsorber tanks (TK02 and TK03) have a threaded connection that can be piped
outside, which ensures that in case of overpressure the oxygen will not be released in the room, but will
be guided to outside.
• Exhaust
In case there is no sufficient ventilation in the room, it is recommended to lead the exhaust of the generator
out of the room, since the exhausted air has an increased nitrogen concentration.
To keep the back pressure as low as possible and to safeguard the performance of the generator, the piping
to the exhaust has to be as follows:
• Length < 3 m (10 ft): connect the exhaust pipe to the muffler.
• Length between 3 m (10 ft) and 10 m (33 ft): the diameter of the regeneration pipe has to be at least
1.5 x larger than the connection of the muffler.
• Length > 10 m (33 ft): consult your supplier.
The exhaust flow can be calculated from:

with
• Pw = working pressure of the generator in bar(e)
• V = generator tank volume in l (see section Pressure equipment directives, table A)
• t(exhaust) = 8 seconds

2920 7120 40 41
 Instruction book

The back pressure during regeneration (after exhaust) must be kept as low as possible. It should not exceed
100 mbar.
•

• Provide sufficient ventilation. An increased nitrogen level resulting from the exhaust
flow may increase the risk for suffocation.
• Divert the safety valves from the oxygen generator and the oxygen buffer tank to the
outside.
• Keep the exhaust open at all times. Do not block or decrease the exhaust pipe opening.
This might cause decreased performance of the generator or even cause the muffler
to explode.
• If no room ventilation is present, and the exhaust is guided outside, also guide the
simulated oxygen consumption from the ball valve (BA10) outside.

Installation guidelines

- It is recommended that the connection of the compressor air outlet pipe is made on top of the main air
net pipe in order to minimize carry-over of possible condensate residue.
Make sure that no dirt particles (e.g. coming from corrosion in the compressed air network can enter
the generator. These particles may be harmful to the generator components.
- Ventilation: depending on how the exhaust air will be vented, appropriate measures have to be taken
to make sure that the oxygen concentration in the room never exceeds 23.5 % or drops below 19 %.
• In many cases, natural ventilation can be sufficient, for example rooms or halls provided with
ventilation openings. General guideline is that ventilation openings should at least have a flow area
of 1/100 of the floor area. The openings should be diagonally opposite to each other and shall
ensure a free air circulation without obstacles. When natural ventilation is not possible, a ventilation
unit should be foreseen with a capacity of approximately 6 air changes per hour. There shall be a
safety warning in case ventilation fails.
• Note that each installation can require specific measures to ensure that the oxygen concentration
in the room never exceeds the mentioned limits. It is the responsibility of the installer to make sure
that adequate measures are taken.
• Special consideration to the ventilation of underground rooms, pits, trenches, etc. is to be given:
since oxygen is heavier than air, oxygen gas tends to accumulate in low lying areas.
- Room oxygen level detection system: When operators are working in the vicinity of oxygen generating
equipment and the oxygen content can rise to a dangerous level, a continuous measurement system
is necessary. A system with a visual/audible alarm is advisable. The oxygen level detection systems
needs to be put in the working area and near the operator.
- Filter drain connections should be connected to a drain collector but must not dip into the water of the
drain collector.
- Use the main cable entry to connect the power supply cable to the unit.
- Make sure that hose length is as short as possible if it is required to measure oxygen at a customer
defined sample point in the network (for example the oxygen tank in front of the application).
- Only use oxygen approved safety valves in the oxygen net an on the buffer vessel.

Warnings

• If a failure in gas supply (e.g. due to a power failure, the activation of an electrical
safety device, or a generator fault) is - even temporarily - not admissible, it can be
advisable to foresee a backup oxygen source to enable provisional supply of gas
(totally or partially automatic).
• To ensure compliance with the standards imposed by the Machinery Directive, the
restart of the generator after the electrical power supply is restored cannot be
automatic. It must be activated manually by the operator.

The figures at the left are the programmed service intervals. For Service interval A, the programmed number
of running hours is 4000 hours (upper row, green) and the programmed number of real time hours is 4380
hours, which corresponds to six months (second row, blue). This means that the controller will launch a service

warning when either 4000 running hours or 4380 real hours are reached, whichever comes first. Note that the
real time hours counter keeps counting, also when the controller is not powered.
The figures within the bars are the number of hours to go till the next service intervention. In the example
above, the generator was just started up, which means it still has 4000 running hours or 4337 hours to go
before the next Service intervention.

Service plans
A number of service operations are grouped (called Level A, Level B, etc...). Each level stands for a number
of service actions to be carried out at the time intervals programmed in the Elektronikon controller.
When a service plan interval is reached, a message will appear on the screen.
After carrying out the service actions related to the indicated levels, the timers must be reset.

Automatic Restart
The controller has a built-in function to automatically restart the generator if the voltage is restored after
voltage failure, called "Automatic Restart".

Provided the controller was in the automatic operation mode, the generator will
automatically restart if the supply voltage to the module is restored within a programmed
time period.
The power recovery time (the period within which the voltage must be restored to have an
automatic restart) can be set between 15 and 3600 seconds or to 'Infinite'. If the power
recovery time is set to 'Infinite', the generator will always restart after a voltage failure, no
matter how long it takes to restore the voltage.
A restart delay can also be programmed allowing for example the generator and the
compressors to be restarted one after the other. This is strongly recommended in case
ARAVF is activated.

To deactivate/activate ARAVF, use password 4735. If ARAVF is activated, this is visible in the Main screen.

By default, "Automatic restart" is deactivated.

5 Operating instructions

5.1 Operation

Start-up procedure

In order to remove contaminating particles, new oxygen equipment or pipe systems shall
be purged with oil-free air (like available downstream the QDT) or with nitrogen before
start-up.

To ensure that the oxygen generator is started correctly, the following procedure must be followed:

Step Description
1 Make sure the inlet ball valve to the generator and the outlet ball valve (BA05) downstream
the generator are closed before starting up the installation.
2 Make sure the sample line (SL01) from the oxygen buffer tank is connected to the oxygen
sensor (GA01) and the oxygen pressure sensor (PT01).
3 Connect the optional inlet PDP sensor (PDP01) and/or the oxygen outlet flow meter (FI01) if
required
4 Switch on the refrigerant dryer 10 minutes in advance of the oxygen generator (if applicable).
5 Start the compressor and see to it that the pressure in the air tank goes up to the required
pressure (for example 7 bar(g) (101 psi(g))).
6 Slowly open the ball valve at the inlet of the generator.
Regulate the working pressure of the generator down to maximum 6 bar(g) (87 psi(g)) by
means of inlet pressure regulator (RV01). Pull the handle of the pressure regulator to unlock
the mechanism.
If the pressure in the air tank exceeds 10 bar(g) (145 psi(g)), use a pressure regulator for the
pilot air of the pneumatic valves (regulate the pressure between 4.2 bar(g) (60 psi(g)) and 8
bar(g) (116 psi(g))).
7 Turn on the generator by pushing the Start button (14) on the Control panel. The generator
will start up and switch towers, based on its programmed time settings.
8 Let the generator run with the outlet ball valve (BA05) closed during 15 minutes before
proceeding to the next step.
9 Partially open the outlet ball valve (BA05) of the generator to the oxygen buffer tank (TK04)
to 1/4 of the full open position. Make sure the air pressure in the air tank slowly builds up to
4 bar(g) (58 psi(g)). This should take at least 20 minutes. Keep the ball valves towards the
customer’s net (BA08 and BA10) closed.
While doing so, monitor the oxygen purity (GA01) on the display of the generator. The oxygen
purity should increase. If the oxygen purity remains at 80% then the outlet ball valve (BA05)
was opened too less or too much.
10 Open the ball valve (BA09) of the oxygen feedback line (SL01) to the oxygen sensor (GA01).
Open the pressure regulator (RV03) to the oxygen sensor (GA01)) and regulate down to
maximum 0,4 bar(g) (6 psi(g)). The flow trough the oxygen sensor is assured by means of a
nozzle (FR01) downstream the pressure regulator (RV03) and is limited to 600 ml/min (36.61
in³/min).
11 When the pressure in the oxygen tank reaches 5 bar(g) and the oxygen purity has reached
a level of 75% or more, gradually open the ball valve (BA05) to full open position.
The pressure in the oxygen tank will increase to a level between 4 and 5 bar(g) (58 to 72.5
psi(g)).

2920 7120 40 95
 Instruction book

Step Description
12 Regulate the outlet flow through the ball valve (BA10) or, for accurate regulation, through the
manual valve (FC01), to 2/3 of the requested nominal flow to reach the requested purity. Make
sure the oxygen pressure (PT01) remains between 4 and 5 bar(g). It is recommended to install
a flow meter with display downstream the pressure regulator (RV04).
These are some typical readings during this step:
• Pressure generator tank A (PI02) and tank B (PI03): 4.8 – 5 bar(g) (70-72.5 psi(g)) at the
end of the production step (before equalization)
• Equalization pressure (PI02 and PI03): 2 bar(g) (29 psi(g))
• Inlet pressure read on inlet pressure regulator (RV01):
• At beginning of half cycle: 5.1 bar(g) (74 psi(g))
• At end of half cycle: 5.6 bar(g) (81 psi(g))
Depending on the size of the oxygen tank it can take 1 to 2 hours (95%) to reach the requested
purity.
While waiting for the requested purity to be reached, proceed with the following steps.
13 Set the time and date in the Settings menu (General settings, Time: see Modifying settings).
Format: dd/mm/yyyy hh:mm:ss
14 In the Protections menu (see Protections menu), set the required warning and shutdown
levels according to the customer’s specification.
15 In the Settings menu (Generator settings, Regulation: Modifying settings), set the Standby
pressures:
See also figure below:
• Stop Pressure: At this oxygen tank pressure, the generator will go into standby to save
energy. To set this pressure, close the outlet ball valve BA08 and BA10, to stop oxygen
consumption. Let the generator fill the tank for 10 minutes, until the pressure does not
longer increase. Note down this pressure value.
• Set the Stop Pressure setting to 0.1 bar(g) (1.5 psi(g)) lower than the maximum pressure
reached in the previous step (no outlet flow). (e.g. if the maximum pressure is 5.4 bar(g)
(78.3 psi(g)), set the Stop Pressure to 5.3 bar(g) (77.8. psi(g))
• Start Pressure: At this oxygen tank pressure the generator will restart from standby
mode. Set this pressure 0.5 bar (7 psi) below the Stop Pressure level (e.g. if the Stop
Pressure level is 5.3 bar(g) (76.9 psi(g)), set the Start Pressure level to 4.8 bar(g) (70
psi(g)).
Note: If the Start Pressure level is too close to the Stop Pressure level, the generator will only
switch a couple of times before entering standby again. Thus the product purity will be
compromised.
If the Start Pressure level is too far from the Stop Pressure level, the buffer pressure will drop
too much, causing the generator to deliver (less pure) oxygen sooner to the oxygen tank
(TK04), and thus compromising the oxygen purity level.
16 Set the Pressure Low Warning to minimum 4 bar(g) (58 psi(g)) in the Protections menu.
17 As soon as the oxygen purity has been reached and the correct Stop Pressure and Start
Pressure levels have been set, put the generator in Automatic operation (See Operation
mode selection.
18 Close the ball valve (BA10) and make sure the generator enters the standby mode. Regularly
check the oxygen purity level and wait until the oxygen purity has stabilized.
If the oxygen generator does not reach the Stop Pressure level, increase the inlet pressure
slightly by turning the inlet pressure regulator (RV01). Increase the pressure in steps of 0.1
bar (1.5 psi), and allow sufficient stabilizing time.
19 Open ball valve (BA10) again to the nominal consumption. At this oxygen flow the generator
will produce oxygen continuous, and will not enter standby mode. Check that the oxygen purity
remains above the requested purity.
20 Close ball valve (BA10). The generator has now been fully set, and is ready for automatic
use.

96 2920 7120 40
Instruction book

Step Description
21 Slowly open the ball valve (BA08) towards the customers oxygen net, keeping the pressure
in the oxygen tank at pressure. If the pressure in the oxygen tank drops too much, the purity
will be compromised.

(4) Oxygen tank pressure
(5) Min. 5 half cycles

Operation mode: Automatic

In Automatic mode, the generator goes in standby when the pressure level is reached in the pressure vessel.
The generator resumes operation when the pressure on the vessel falls below the minimum standby pressure
(Pressure Start).

Operation mode: Manual

In Manual mode, the generator runs all the time independent of the consumption. It operates continuously,
never goes in standby.

Alarm with auto stop position: Minimum Purity

If the purity is lower than the value set as Minimum Purity, the generator shuts down.
The limit for this alarm is set in accordance with the customer requirements (See Modifying settings).

Start-up procedure after Alarm stop: Low Oxygen Pressure

If this alarm is active, you must follow step 9 to 22 in the Start-up procedure to get the system up running
again (See Protections menu).

2920 7120 40 97
 Instruction book

Stop procedure
When the generator needs to be stopped, the next procedure must be followed:

Step Description
1 Close the outlet ball valve (BA05) of the generator. If required also close the outlet flow from
the oxygen buffer tank (BA08). (This will allow a faster restart).
2 Press the Stop button on the control panel. The generator will finish the cycle.
3 Wait until the generator has finished the programmed cycle and has stopped. At the end of
the cycle the generator will equalize the pressure in the tanks, and will stop.

Note:
The oxygen sensor (GA01) will keep on consuming oxygen via the feedback line (SL01) from the oxygen
buffer tank (TK04). If this is undesirable, close the ball valve (BA09) to the oxygen sensor (or close the
pressure regulator to the oxygen sensor (RV03), if the ball valve is not installed).
If an optional PDP sensor (PDP01) is installed, the ball valve (BA04) to the optional PDP sensor needs to be
closed off as well.

Restart procedure
When the generator needs to be restarted after a stop, the next procedure must be followed:

Step Description
1 Remove the plug from the oxygen sensor (if this was fitted)
2 Open the ball valve (BA09) to the oxygen sensor (GA01) (or open the pressure regulator
(RV03) to the oxygen sensor, and set it to max. 0.35 bar(g) (5 psi(g)).
3 Open the ball valve (BA04) to the optional dew point sensor if applicable.
4 Make sure the refrigerant dryer and compressor are started, and that the air tank is
pressurized.
5 Set the operation mode to Automatic. The oxygen generator will restart.
6 Slowly open the ball valve (BA05) at the outlet of the generator.
Let the buffer tank fill up for about 20 minutes and make sure the oxygen purity is above 80%.

Changing the purity

The nominal flow of an oxygen generator is stated at an outlet purity of 90%. If you want the purity to be
increased, the outlet flow needs to be decreased. Please refer to the outlet flows and their corresponding oxygen
purity stated in the technical data. As a guideline, the following rule can be applied:

O2 purity Outlet flow (as percentage of nominal flow)

90 % 100 %
93 % 90 %
95 % 80 %

The settings (start- and restart pressure) of the automatic mode do not need to be modified.

5.2 Checking the display

Check the display regularly for readings and messages. The display normally shows the generator outlet
pressure, outlet purity, membrane working pressure and generator inlet temperature, and the abbreviations of
the functions of the keys below the display.
Always check the display and remedy the trouble if alarm LED is alight or blinks, see section Icons used.

5.3 Taking out of operation

Procedure

Step Action
1 Stop the generator and close the air inlet and oxygen outlet valve.
Close all sample air connections connected to the sample system of the oxygen analyser.
2 Switch off the voltage and disconnect the generator from the mains.
3 Shut off and depressurise the part of the air net which is connected to the oxygen outlet valve.
4 Drain the condensate circuit and disconnect the condensate piping from the condensate net.

Due to the slow desorption process of the molecular sieves, the pressure in the adsorber
vessels might increase over time. This overpressure will prevent against unwanted
adsorption of moist air from ambient.

6 Maintenance

6.1 General recommendations and precautions

Safety
Before carrying out any maintenance or corrective activity read the following recommendations and safety
precautions and act accordingly.

• Close the generator's outlet valve and the air inlet valve and wait until machine working
pressure is 0 bar.
• Switch off the generator.

The release of nitrogen molecules from the MS is a very slow process. This might cause
a pressure build-up in the generator tanks, even after they were depressurized.
Before maintenance, make sure the generator is fully depressurized and purge thoroughly
with air to remove all oxygen before service or inspection.
Always vent oxygen to the outside atmosphere.
Due to fire hazard, smoking and the use of open flames are prohibited in the vicinity of the
oxygen generator.
Avoid closing valves too fast as gas velocities in the oxygen net might become too high,
and create a hazardous situation.

Warranty - Product liability

Use only authorized parts. Any damage or malfunction caused by the use of unauthorized parts is not covered
by Warranty or Product Liability.

Service kits
For overhauling and for preventive maintenance, a wide range of service kits is available. Service kits comprise
all parts required for servicing the component and offer the benefits of genuine spare parts while keeping the
maintenance budget low.
Consult your Atlas Copco Customer Centre.

Service contracts
Atlas Copco offers several types of service contracts, relieving you of all preventive maintenance work.
Consult your Atlas Copco Customer Centre.

6.2 Maintenance schedule

To maintain the generator efficiency and to reduce the risks of faults, strictly observe the recommended
maintenance schedule.
On the Main screen, the remaining number of hours before service is displayed. This is a counter that counts
down from 4000 hours. For more information, see Service menu.

(1): whichever comes first

After maintenance activities, the service counter needs to be reset. Contact your supplier.
All spare parts required for scheduled maintenance are included in the specific Service kit. Part numbers of
the Service kits can be found in the spare parts list of the oxygen generators.

Due to its working principle, the oxygen analyzer contains traces of lead. Please dispose
of it in accordance with the environmental regulations.
Also the used MS (molecular sieves) need to be disposed of in accordance with the
environmental regulations.
Proper and timely maintenance is extremely important to safeguard the lifetime of the MS
bed. The manufacturer cannot take any responsibility for improper functioning of the
generator if maintenance is not done as prescribed. In this respect, regular maintenance
of all equipment upstream of the oxygen generator, including but not limited to the
compressor and the filter package used is of extreme importance. For maintenance
instructions of this equipment, please be referred to the instruction manual of the
equipment involved.

When performing maintenance on pneumatic valves that come in contact with oxygen,
make sure the valves are greased with oxygen approved grease (such as
Paraliq_GTE_703) or lubricants. Do not use regular grease, lubricants or oil, as these can
self-ignite or even explode when in contact with oxygen.

Maintenance of the QDT filter is crucial to prevent oil from coming in contact with oxygen!

7 Adjustments and service

7.1 Calibration of the oxygen sensor

General information
The zirconium type sensor does not need to be calibrated periodically because the outlet signal and the
deviation are guaranteed to be stable during the 5 year lifetime of the sensor. To confirm this, a yearly check
of the calibration according the procedure described below is recommended.

7.3 Adjustment of flow sensor

Introduction
The Flow sensor (FI01) is optional and can be ordered in case a measurement of the outlet product flow is
required; it measures the flow rate consumption. The flow sensor is to be installed downstream the buffer
tank (TK04), behind the pressure regulator (RV04).
Two types of flow sensors are available, depending on the model:
• CS VA420
• Endress+Hauser 65F15

8 Optional equipment

8.1 Inlet Pressure dew point

An inlet pressure dew point sensor (PDP01) is available as an extra measure to protect the generator against
a too high inlet dew point. The Molecular Sieve material, that adsorbs nitrogen molecules, can perform less
or even get damaged by too high water vapor concentration in the inlet air. In general the inlet air dew point
needs to be less or equal to +3 °C.
This option monitors the inlet pressure dew point and generates a warning in case the dew point rises above
+5° C. When the dew point rises above +8 °C the generator will shut down, to prevent the molecular sieves
to be irreversibly damaged. These warning and alarm levels can be set in the <User Settings> screen.
Contact Atlas Copco for more information.

9 Trouble shooting

Pressure Low warning

This alarm is activated after excessive consumption of oxygen at the utility. The pressure in the oxygen tank
(TK01) falls below the set pressure low warning value.
To exit the alarm condition, reduce the oxygen flow rate to the utility to enable the pressure in the oxygen
tank to rise above the minimum set value.
Check that the feedback line (SL01) from the oxygen storage tank (TK04) is connected to the oxygen pressure
sensor (PT01), and that the ball valve (BA09) is in open position.

Purity Low Warning

When the concentration of oxygen in the oxygen tank (TK04) exceeds the warning level, the purity low
warning alarm is triggered. The oxygen generator will keep on producing oxygen.
Check the following possible causes:
• Check that the feedback line (SL01) from the oxygen storage tank (TK04) is connected to the oxygen
pressure sensor (PT01), and that the ball valves are in open position.
• Variation in operating conditions, in particular a decrease of the compressed air pressure at the inlet of
the generator or increased ambient temperature.
• Unsuitable quality of the compressed air at the inlet (presence of oil and/or condensate will damage the
adsorbent).
• Malfunction of the oxygen analyzer. Check the reading of the oxygen sensor (GA01) by applying ambient
air or a reference gas to the oxygen sensor.
• The generator enters standby mode frequently. Check the time needed to reach the Stop Pressure level
and adjust if necessary. If the Stop Pressure level is reached too fast, the generator will not have had the
time to produce oxygen of the required purity. Increase the Stop Pressure level if needed.
• The generator enters standby mode: Check the Start Pressure level, and adjust if necessary. In case the
Start Pressure level is too low, the purity can go bad. Increase the Start Pressure level if needed.
If the alarm persists, contact Atlas Copco for technical assistance.

Purity Low shutdown

This alarm is only active in Automatic operation.
When the concentration of oxygen in the oxygen tank exceeds the shutdown level, the purity low shutdown
alarm is triggered. The oxygen generator will immediately shut down.
Acknowledge the alarm as mentioned in the operating instructions.
To restart the generator, follow steps 5 to 14 of the start-up procedure. Check the following possible causes:
• Check that the feedback line from the oxygen storage tank (TK04) is connected to the oxygen pressure
sensor (PT01), and that the ball valve (BA09) is in open position.
• Variation in operating conditions, in particular a decrease of the compressed air pressure at the inlet of
the generator or increased ambient temperature.
• Unsuitable quality of the compressed air at the inlet (presence of oil and/or condensate will damage the
adsorbent).
• Malfunction of the oxygen analyser. Check the reading of the oxygen sensor (GA01) by applying ambient
air or a reference gas to the oxygen sensor.

2920 7120 40 115

 Instruction book

• The generator enters standby mode frequently. Check the time needed to reach the Stop Pressure level,
and adjust if necessary. If the Stop Pressure level is reached too fast, the generator will not have had the
time to produce oxygen of the required purity. Increase the Stop Pressure level if needed.
• The generator enters standby mode: Check the Start Pressure level, and adjust if necessary. In case the
Start Pressure level is too low, the purity can go bad. Increase the Start Pressure level if needed.
If the alarm persists, contact Atlas Copco for technical assistance.

Flow High warning

If the flow meter (FI01) is installed, the flow high warning alarm will be triggered whenever the customer
consumes more oxygen then the value set into the parameter screen. Basically this is an extra notification to
prevent impure oxygen delivery due to excessive oxygen consumption.

Dew point High warning (optional)

This alarm is triggered when the inlet pressure dew point exceeds the set value, whenever the optional PDP
sensor (PDP01) has been installed and configured (typical value +5 °C).

Dew point High shutdown (optional)

This alarm shuts down the generator when the inlet pressure dew point exceeds the set value, whenever the
optional PDP sensor (PDP01) has been installed and configured. As such the generator can be protected against
too high pressure dew points (typical value +8 °C).

time the towers are pressurized (every 60-80 s approximately) there will be an air consumption peak during
a few seconds which can be 3-4 times the average consumption. Therefore it is important to size the air tank
correctly. During testing of the units, rejection limit is maximum +5 % on the air demand.

Recommendation of the manufacturer for the re-inspection time

Following actions are to be executed by authorised service personnel, unless stated differently in the applicable
legislation. The stated time interval has as reference the day of start-up of the unit.
• Every 6 months: visual check of the vessel (tank) material on the outside (exposed) for traces of strong
corrosion. Consult the service department of your supplier if necessary.
• Further re-inspection of the pressurized components should be carried out according to the local
regulations. Contact your Notified Body for more information.

Before inspection make sure the generator is fully depressurized and purge the pressure
components thoroughly with air to remove all excess of oxygen. Always vent oxygen to
outside atmosphere. Make sure there is no smoking or open flame.
