Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent to
the application(s) it is supplying. If this is not convenient then the unit can be sited
elsewhere, however, consideration should be made of the lengths of pipe runs as
pressure drops can result from extended runs of pipe.
Performance of the generator (like all sophisticated equipment) is affected by ambient
conditions. Note should also be taken to the proximity of Air Conditioning outlets.
These can sometimes give rise to “pockets” of air with high relative humidity. Operation
of the unit within such a pocket could adversely affect its performance. Consideration
should also be given to the air flow around the unit. It is recommended that an air gap
of 75mm (3”) should be maintained down both sides and at the rear of the unit. Please
refer to the drawing below for the general dimensions of the unit.
Minimum Operating Ambient Temperature:

5 °C (41 °F)

Maximum Operating Ambient Temperature:

If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment maybe impaired.
WARNING

Page 17

Start-Up Sequence
Once connected to the mains supply the generator can now be switched on. Flick the
power switch on the front panel of the generator to the on position
The first time the unit is switched on it will ask you to confirm that the transit brackets
have been removed. The unit will not start until the user has pressed the confirm
button.

The unit will then start an installation diagnostics sequence. The diagnostics will
take approximately 20 minutes to complete. A progress bar is shown to indicate the
progress of the tests. This is not an indication of time.

During the diagnostics the user will be asked to confirm that the tubing connected to
the drain outlet is secure and that if it is connected to a drain container that it is empty.
The diagnostics will be paused until the user presses confirm.

WARNING

During diagnostics air is expelled through the drain outlet at pressure.
Please ensure that the tubing is secure. If a drain bottle is used please
ensure that it is empty before carrying out a diagnostics check as
water may be sprayed from the container.
The drain bottle should NOT have an air tight seal.

WARNING

CAUTION

Page 18

It should be noted that the gas pressures and flows are factory set.
The pressures shown on the Generator front panel are in excess of
the maximum inlet pressure of the Mass Spectrometer. This is to allow
for known pressure drops. These settings have been approved by AB
Sciex.

CAUTION

Once the tubes are connected to the appliance, ensure that they are
thoroughly checked for being leak-tight. Even the slightest leak in the
gas supply between the Generator and the application can lead to a
reduction in efficiency, or possible alarm of the Generator.

The diagnostics sequence will only run on subsequent start-ups if there was a problem
detected before it was shut down. If no fault had previously been detected and the
installation diagnostics has been completed, a start-up screen will appear for 30
seconds to allow the user to initiate a diagnostics check. This is recommended if the
unit has been turned off for a long period or the generator has been moved.
Once diagnostics have completed the generator will take a couple of minutes to
become ready for use.

Once pressure is within the normal operating limits the buzzer will sound two short
beeps to signify the generator is ready for use. A reminder to register the Generator
with Peak Scientific will be displayed.

Once you have registered the generator pressing [Acknowledge] will prevent this
message appearing again. Pressing [Remind me later] will display the message again in
one and a half hours. You can register online at http://www.peakscientific.com/serviceand-support/warranty-registration

CAUTION

Page 19

Before the Generator is connected to the Mass Spectrometer the
Generator should be operated in isolation (i.e. not connected to the
Mass Spectrometer) for thirty minutes after the start up diagnostics
have completed. This is to ensure any impurities present are purged
from the system. Failure to do this may harm the Mass Spectrometer.

Operating Modes
The generator can operate in a number of modes depending on the gas demand
from the Mass Spectrometer and the health of the generator. The operating mode is
displayed on the main screen of the HMI. The operating mode will change automatically,
no user intervention is required.

Normal Operation
The Genius AB-3G Gas Generators are designed specifically to minimize operator
involvement. Given that the systems are installed as described in earlier sections and is
serviced in accordance with the specified maintenance recommendations (see Service
Requirements), then it should simply be a matter of turning the Generator on when it is
required.
The Generator will automatically produce the factory set flow and pressure as detailed
in the Technical Specifications.

Standby Mode
The generator will detect when the Mass Spectrometer enters standby mode. Due to
the reduced gas demand the Generator controls the compressors differently to help
extend compressor life.
It should be noted that even in standby the Mass Spectrometer still consumes a small
amount of Nitrogen and Dry Air. This in turn reduces the receiver pressure within the
Generator causing the compressors to start up. This is normal in Standby Mode.
The operating mode on the main screen will change to Standby Mode.

High Altitude Mode
High altitude mode allows the Generator to operate easier at high altitude. In this mode
both air compressors run together during Normal Operation. Consult with your local
Peak Representative before enabling this function.

CAUTION

It should be noted that this will increase the duty on the compressors
and reduce time between services. This mode should only be used
where required.

The main screen will now display “High Altitude Mode” instead of “Normal Operation”

Page 20

HMI User menus
The AB-3G’s advanced control system employs an easy to navigate menu system to
give the user additional information about the Generator. The menu is accessed by
pressing the [Menu] button on the main screen.

User Menu
The user menu gives access to the following functions

Run hours
Displays:
•

Unit on time – The total time the unit has been turned on.

•

The date the next annual service is due.

•

Compressor run times – The time that each compressor has actually been running.

Temperatures
The AB-3G monitors ambient (room) temperature and the temperature within the
compressor cabinet inside the generator as part of the temperature alarm system. The
information on this screen is a live reading of these two temperature inputs. The alarm
set points can be accessed via this screen also.
Page 21

System status
The status of each component within the Generator is displayed. This includes the three
compressors and all of the solenoid valves used within the system. This can be used
should a fault be detected to show which components have failed.

Event logs
The event logs record the date and time of all system events. These are split into two
logs
•

System Faults

•

Temperature alarms

System faults log the error code along with the date and time. Recent error codes
should be noted and passed to your service provider if you are reporting a fault. The
last twenty faults are logged.
Temperature alarms will record every time a temperature warning or over temperature
shutdown occurs. The last ten faults are logged.

Set time/date
The date and time, as displayed on the main screen, is set here. Setting the date and
time ensures that any events a correctly logged.

Comp hours reset
When a compressor is serviced or replaced the run hours of the compressor need to
be reset here. This screen is password protected. A password will be included in the
instruction manual provided with your replacement compressor or compressor service
kit.

High Altitude Mode
This allows High Altitude Mode to be enabled or disabled

Event message
This displays details of the current error if either of the fault icons are displayed on the
main screen.

Service Engineer
This is a password protected area of the controls. A caution screen is displayed to
allow the user to go back to the main menu. Access is only granted to qualified service
personnel. Please contact Peak Scientific if you require training.

Page 22

On Demand Gas
The generator will produce nitrogen on demand. If the application is operating
and requires a gas flow, the system it is connected to will supply this to suit the
requirements of the application. If the application requirement for gas stops, the system
will also stop, once it has reached its upper set limit in the internal storage tanks. If the
demand from the application starts again, the system will detect the demand for gas
and will automatically start again to suit the demand.

Generator Cycling
The Generator is designed for the internal compressors to cycle. This cycling reduces
the duty (run time) on the compressors. The rate at which they cycle will be dependent
on the gas required to satisfy the demand of the application. If the application demands
the maximum gas flow of the Generator, the compressor duty will be higher, (the rest
period in the compressor cycle will be shorter). If the application demand is lower than
the maximum gas flow, then the duty on the compressors will decrease, (the rest period
in the compressor cycle will be longer). If the Generator is installed in an extreme
environment or is subjected to low supply voltage or high altitude the compressors may
undergo periods where they do not cycle.

Unusual Operation
If at any time the generator begins to emit excessive noise or vibration, then it should
be switched off and you should contact Peak Scientific or the Peak Partner from which
the generator has been purchased.HeaderHeader

Page 23

Fault Warning
Should the unit detect a fault, a message will be displayed on the HMI to explain the
fault and inform the user of the current status of the machine. There are three levels of
fault.
•

Minor fault

•

Redundancy mode

•

System failure

•

Temperature alarm

•

Run time alarm

A minor fault is shown when one of the valves used during diagnostics has failed.
These are set to fail in the normal operating mode therefore the system can function
as normal. You should contact your service provider to rectify the problem at your
convenience
Redundancy mode is likely to indicate a failed compressor. The unit will continue to run
with the remaining two compressors. An intermittent audible alarm will also sound to
alert the user. This alarm can be silenced.
A system failure means that the unit can no longer supply gas and will be shut down.
An audible alarm will sound constantly to alert the user. This can be silenced.
A temperature alarm is to ensure the generator is not being operated over the specified
maximum temperature (30°C). The temperature within the internal compressor
cabinet is also monitored to ensure that they are properly cooled. If the Generator is
operated above the maximum temperatures then damage can be caused to the internal
compressors and the membrane separators.
Run time alarm monitors the length of time that the compressors have been running. If
everything is working properly the compressors should cycle regularly. If a compressor
has not cycled but is still maintaining pressure the Generator will continue to operate. A
run time alarm will generally mean there is a problem with the system which may lead
to system failure. Your service provider should be contacted immediately.
Once the fault message has been acknowledged by the user an icon will be displayed
on the main screen as a reminder.

Page 24

Connecting to the application
Once the initial purge run of 30 minutes has completed, and the generator has been
running for 1 hour, it is ready to be connected to the application(s).
The pressure in the internal storage tanks must be allowed to dissipate
before connecting the generator to the application(s)
CAUTION

Attach the appropriate fittings to the outlets of the generator. Using the tubing
supplied, connect the outlets of the generator to the inlets on the application.
If you require more tubing than is supplied please refer to the Tubing Lengths section.

CAUTION

Once the tubing is connected to the application, please ensure that it
is thoroughly checked for being leak-tight. Even the slightest leak in
the gas supply between the generator and the application can lead to
a reduction in efficiency.

Tubing Lengths

CAUTION

The diameter of the tubing which will be connected to the gas outlet is
important and is determined by the length of tubing required. Failure
to follow these recommendations could lead to pressure between
generator and application.

< 10 meters:

Use 6/4 (6mm O/D, 4mm I/D) P.T.F.E. tubing.

> 10 - 40 meters:


Use 10/8 (10mm O/D, 8mm I/D). Tubing and fittings not
supplied in the fittings kit.

> 40 metres:


Please contact Peak Scientific with the relevant distance andwe
will calculate the flow resistance and the tubing size required.

A combination of 6/4 and 10/8 tubing may be used to ensure that there is no large
diameter tubing within the lab (i.e. for the first 20 meters from the Generator use 10/8
and the final 10 meters to the application use 6/4 tubing). Keep the connections and
bends to a minimum.

The imperial equivalents are: 6/4 = 1/4” O/D, 3/16” I/D.
10/8 = 3/8” O/D, 5/16” I/D.
