The test cycle can be divided in six main blocks:
1. Connection of Tested Object.
2. Pre-Evacuation of Residual Air.
3. Filling with Tracer gas.
4. Tracer gas Leak Test.
5. Removal and Venting of Tracer gas.
6. Disconnection of Tested Object.
The different steps of the connection and disconnection
sequences, even if controlled by the ILS500 tooling
system, is a matter of fixture design for which we can
not give any general advice. Be aware, though, that the
faster the connection is made the higher the risk for
injury. Be careful and install guards etc, according to
local legislation and safety standards so that your fixture
is safe to use.
There are, however, details of how the test fixture is
connected to the ILS500 that affects the cycle time.
Installation factors affecting fill speed:
• Length of tubing between ILS500 and tested object.
• Inner diameter of tubing between ILS500 and tested
object. Consider the smallest diameter in the connection.
This section is a guide for optimising steps number 1,
2, 3 and 5.
The gas test step is not handled here. For optimising
this part refer to the application manual, “The Hydro-
gen Method”.
To obtain the full benefit from using the ILS500 you
should follow the rules below:
• Use both test ports. I.e. connect to two ports on the test
object.
• Smallest diameter in connection between test ports
and tested object (including fittings etc.) should not be
smaller than 8 mm (0.31”). Gas valve bore is 7 mm
(0.28”).
• Place ILS500 close to test fixture to make length of
tubing between test ports and object as short as possible.
• If object has more than 2 ports. Connect to ports on
“opposite sides” of object. This minimises the need for
pre-evacuation.
1. Optimising the Test Cycle
1.1 Optimising the Connection of Test Object
4 Adixen Sensistor - Technical Manual ILS500
First you should determine how deep the pre-evacuation
needs to be or if it can be skipped altogether. To do this
you must fully understand the role of pre evacuation.
See also last paragraph in this section describing an
alternative filling procedure that does not require pre-
evacuation.
When your test object is connected it holds one
atmosphere of ambient air. It is often necessary to
remove some or most of this air before filling with tracer
gas.
There are two effects of not removing the air (i.e. pre-
evacuating):
1) The actual hydrogen concentration will bereduced
Example: The fill pressure is 0.05 MPa (7.2 psi) above
atmosphere (gauge pressure). The object has 1 atm =
0.1 MPa of air before filling. Leaving this air in the
object means the average tracer gas concentration will
be:
I.e. the average hydrogen concentration is only a third
of that expected (5% x 33% = 1.7%).
Pre-evacuating down to –0.7 atm (–0.07 MPa) means
there will be 0.3 atmospheres (0.03 MPa) of residual
air in the object before filling. This gives the following
average concentration:
I.e. the average hydrogen concentration will be 0.8 x
5% = 4% which is almost twice of that achived with no
pre-evacuation.
2) The tracer gas does not reach all parts of theobjectThe air left in the object can not always be expected to
mix evenly with the injected tracer gas. This is especially
so for tube shaped objects such as pipes etc. The flow
inside a regular “tube” is predominantly laminar. This
means no or very little turbulence occurs. Air left in the
“tube” will therefore be pushed in front of the injected
tracer gas and end up in the remote end of the “tube”.
Example: The test object is an aluminium pipe for a
refrigerator with brazed copper ends. The joints between
copper and aluminium must both be tested. Fill pressure
is 0.5 MPa (72 psi). Length is 10 m (33 ft). Skipping
pre-evacuation we will have:
of air left in the pipe. This is equivalent to 1.7 m (5.7 ft)
of the total length if no turbulence occurs during filling.
There is an evident risk that there will be only air inside
one of the joints, which means that a leak there will
remain undetected.
Pre-evacuating down to –0.7 atm (–0.07 MPa) means
there will be 0.3 atmospheres (0.03 MPa) of residual air
in the pipe before filling. We will now have:
Of air left in the pipe. This is equivalent to 0.57 m (1.9
ft). This air volume is normally small enough to be mixed
into the tracer gas by turbulence and diffusion.
The fastest way to fill a pipe like object is often to use
the so called push-through filling, that does not require
pre-evacuation. See Section 1.5.

Testing need for pre-evacuation.By far the best way to establish the need for pre-
evacuation is to make a realistic test.
1. Find a test object with a small leak in a difficult posi-
tion. Difficult meaning far away from test connection
so that the tracer gas does not readily reach the leak.
2. Set the H2000 PLUS detector in Analysis Mode.
3. Set up ILS500 according to your test specification.
4. Set Pre-Evacuation Level to –0.07 MPa (–10 psi).
5. Purge the object thoroughly with compressed air.
6. Check with hand probe that there is no Hydrogen in
the part.
7. Connect the object.
8. Place the hand probe on the leak (no signal should be
heard).
9. Press Start on ILS500.
10. Register the Signal from the leak. The gas signal
should stabilise quickly and the maximum achieved sig-
nal should be attained in a maximum of 2 seconds after
that the fill setpoint has been reached.
• Set the Pre-evacution Setpoint to half of the previous
and repeat the test from step 5.
• The new pre-evacuation is adequate if the gas signal
is essentially the same and develops at the same speed.
• Reduce Pre-evacution Setpoint further and repeat test
again to find the lowest suitable Pre-evacution Setpoint.
If you can not perform this test there are a few guide
lines:
• Higher test pressure (Fill Setpoint) means less need
for pre-evacuation.
• Round shapes like tanks require less pre-evacuation.
• Pipes etc need deeper pre-evacuation.
• Pipes etc will exhibit considerable pressure drop along
its length during the evacuation. This means the pressure
in the pipe can be much closer to atmosphere than what
is registered by the ILS500. Set the ILS500 to evacuate
through Test Port 1 only (this is done in the Advanced/
Options Menu). In this way the vacuum will be regi-
stred in the other end of the pipe and the evacuation
will be at least as deep as set by the Pre Evacuation
Setpoint.
If this is not possible, add some extra time by setting an
Extended Evacuation Time.
If still in doubt, play it safe and set pre-evacuation to –
0.07 MPa (–10 psi). this will evacuate 70% of the air
which should be adequate in almost every case.

HAZARDNever pressurise system or object aboveapproved pressure. Too high pressure canresult in death or serious injury!
Regulation of the tracer gas pressure can either be controlled
by the ILS500 or by an external pressure regulator.
The ILS500 is set to regulate internally as default.
In either situation it is important that the tracer gas supply
pressure (feeding the ILS500 tracer gas inlet) is set up
properly. This is primarily a safety issue.
Check the following:
• Feed pressure must never be above the maximum pressure
allowed for object to be tested.
• Feed pressure must never be above the maximum pressure
specified for the ILS500, 1.0 MPa (145 psi) for the stan-
dard model.
External Pressure Regulation: Tracer gas pressure is
controlled by external regulator. ILS500 simply opens a
path between the gas feed line and the test object. The
pressure will equate and the tested object will attain the
pressure delivered by the external regulator. ILS500 checks
that the fill pressure is above Fill Setpoint before procee-
ding to the next test step.
The tracer gas filling step will be failed if the
Fill Setpoint is not attained within the Fill Timeout.
External regulation is recommended mainly for very small
objects (<50 cc).
N.B. External Pressure Regulation does not support recipes
with different test pressure (i.e. fill setpoints).
Internal Pressure Regulation: Tracer gas pressure is
controlled by the ILS500.
Internally regulated filling is generally faster than externally
regulated. The reason for this is that the feeding pressure
can be set higher than the Fill Setpoint which results in a
higher fill flow.
The ILS500 regulation is a simple and robust ON/OFF re-
gulator controlled by the parameters listed below:
Fill Setpoint: The desired tracer gas fill pressure (i.e. test
pressure).
Fill Timeout: The object will be rejected if the Pressure
Setpoint has not been achieved within this time.
Supply Pressure: Pressure fed to tracer gas inlet port.
N.B. This is not a software parameter.
Pulse Fill from (%) of Fill Setpoint: Fill function will
switch from continuous filling to pulsed filling at this level.
Fill Pulse Open: Open time for gas fill valve during pulsed
filling.
Fill Pulse Closed: Closed time for gas fill valve during
pulsed filling.
Extended Gas Fill: Extends filling after the fill set-point
has been attained.
Refill Hysteresis: Hysteresis for gas refill. Gas refill will
start if pressure drops below setpoint minus Refill Hysteresis.
Refill Timeout: Maximum time for refill before object is
rejected. Refill occurs if pressure drops below Fill Setpoint
– Refill Hysteresis after a successful filling.
1.3 Optimising the Tracer gas Filling
7Adixen Sensistor - Technical Manual ILS500
Optimal filling is when:
• Filling is fast.
• Resulting pressure is within ±5% of the
Fill Setpoint.
• Number of fill pulses is 1 – 2.

Use the table below when adjusting the parameters to
achieve optimal filling. Start with the default settings
and then adjust the parameters in the order given from
top to bottom. The supply pressure and the “Pulse Fill
from (%) of Pressure Setpoint” parameter are normally
the only parameters you need to adjust.
1.4 Adjusting the parameters for internally regulated filling
Set Pulse Fill from (%) of Pressure Setpoint to 100 in order to disable pulse
filling.

Push-through filling is an alternative filling method for
filling elongated objects quickly. Cycle times can be
significantly reduced at the expense of an increased tracer
gas consumption.
An elongated object here means a pipe or other long
tube shaped object. This type of object normally requires
deep pre-evacuation since the gas will flow in laminar
fasion and not mix with air in the object. The residual
air will simply be pushed in front of the injected gas.
In push-through filling this air is pushed through the
“pipe” and into an additional volume. This added volume
is placed between the object and Test Port 2 (See figure).
ILS500 must be set to fill through Test Port 1 only. This
option can be found under Advanced Setup / Parameters
/ Options, Section 8.4.9.
The added volume should be:

Example: The test object is an aluminium pipe. Fill
pressure is 0.5 MPa (72 psi) = 5 atm. Length is 10 m
(33 ft) with an internal volume of 280 cc. Internal volume
of connections is 120 cc in total:
V > = 96 cc
Add a 100 cc volume between the object and Test Port
2.
As mentioned above this procedure saves a considerable
amount of cycle time. The disadvantage is a higher
consumption of tracer gas.

The main reason for removing the tracer gas is to
minimise the amount tracer gas in the ambient around
you test station. Leaving large amounts of gas in the
tested object can cause interference with the testing.
This is especially true for automatic testing. An opera-
tor testing manually can normally interpret spurious
signals as irrelevant. The computer controlling an
automatic test does not have that capability and back-
ground “noise” can result in false leak signals.
The optimum tracer gas removal is therefore always a
balance between cycle time and risk for false rejects.
The Air Purge function is normally the quickest and
most efficient way of removing the tracer gas from the
tested object. See further under tooling.
An alternative to removing all gas is to use a ventilation
hood above the “box” or pallet where the objects are
placed after testing.
As a start we recommend that you activate After
Evacuation and set the After Evacuation Setpoint to –
0.03 MPa (–4.4 PSI).
Use the Air Purge function if you are using the tooling
function.
Set the Purge Object timer so that there is only very
little gas left in the object after the test. Use the hand
probe to check.

3. Service Menu
The Service Menu contains functions for trouble
shooting and testing of the system.
The software versions are displayed in the lower right
corner. This might be requested when communicating
with the supplier or his appointed service partner.
3.1 OutputsThe PLC OUTPUTS menu shows the current status of
each system output.
A black box means output is ON.
You can manually override the status of all outputs that
are in off state. Simply press on the respective box. N.B.
You can not turn off an output set to high by the system.
3.2 InputsThe PLC INPUTS menu shows the current status of
each system input.
A black circle means input is ON.
This is a display only. You can not affect the state of the
inputs from this display.
20 Adixen Sensistor - Technical Manual ILS500
3.3 Analogue Inputs ConfigurationThis menu is primarily used for analysing the signal
and noise of the vacuum and pressure sensor signals.
Channel 1: OptIn 1. Analog / digital input. Not
supported by std software.
Channel 2: OptIn 2. Original Adixen Sensistor
accessories, for example. Active Holder for
Hand Probe.
Channel 3: Vacuum sensor
Channel 4: Pressure sensor.
The k and m of the linear correction for the vacuum and
pressure sensors are set to give readings in “bar”. Do
not change k and m for another unit. System base unit
must be “bar”.
The only reason to change the k and m is to fine tune
the calibration of the respective sensor.
Do not make bigger adjustments than 5% for “k” and
20% for “m”.
If bigger adjustment is needed you should instead replace
the sensor.
N.B. The system readjusts the zero point during the start
up procedure. Try to restart the system before adjusting
the m parameter.
Important! Do not change the input mode setting as
this will result in malfunction of the sensor scaling.
21Adixen Sensistor - Technical Manual ILS500
3.4 System ResetA system reset will set all current parameters to factory
default as given in the Parameter Index in the User Ma-
nual.
Recipes and passwords will not be reset.
Press and hold STOP button more than
3 seconds to display this choice. Tick
box while pressing STOP button to reset
recipes, passwords and A/D con-
figuration.
3.5 H2000 SettingsThis menu gives easy access to all H2000 parameters
that are controlled from the ILS500.

B: Calibration Coefficient
C: Leak Rate Unit (A, B and H must all
be expressed in this unit)
D: APC Timer A
E: APC Timer B
F: APC Timer C
G: APC Timer D
H: Purge Level
Open the “APC Settings” in the H2000 PLUS for
specific description of APC Timers A through D.
The X marks behind the parameters controls whether
the respective parameter is downloaded to the H2000
PLUS upon recipe changes.
Downloading all parameters takes roughly 10 seconds.
By restricting the download to only those parameters
that differs between the different recipes, you can reduce
this time, making recipe selection quicker.

3.7 Service RunThis menu is intended for remote trouble shooting per-
formed by an authorised service centre.
3.8 Hardware TestThe hardware test is a diagnostic tool helping you in
preventive maintenance as well as service and repair.
The test takes you through a number of steps testing all
units that are subject to wear and should thereby help
you to find almost any problem in the ILS500 system.
Keep this manual at hand when performing the test.
You will need the reference table at
the end of this section to help you interpret the test results
correctly.
Remember also that you will need to run through the
whole sequence to interpret the results correctly.
You can choose to test according to the limits of your
specific application.
Setup all parameters for your test object (or load desired
recipe) and connect a leak free sample.
Set test selection switch to ”ILS500 + Object” for
application specific hardware test.
You can also test the ILS500 against factory
specification.
In this case you should plug both test ports using the
plugs delivered with the units.
(Remove ISO to NPT converters if installed.)
Set test selection switch to ”ILS500 plugged” for factory
specified hardware test.

4. MaintenanceILS500 has been designed for a minimum of
maintenance. Regular maintenance is done easily and
quickly using simple and commonly available tools.
There are only three different parts that need regular
maintenance:
• Venturi pump (1 off). The pump will need regular
cleaning.
• Gas Valves (4 off). The gas valves will need regular
cleaning. The gas valves will eventually wear out and
need to be replaced.
• Pilot valves (6 off). Maintenance free, provided that
incoming compressed air is dry and filtered to 5 µm.
The Venturi pump and all gas valves can be tested
automatically by the Hardware Test. See Section 3.8.
Changing Venturi pump and all gas valves takes less
than 15 minutes.
4.1 ToolkitBelow is a list of the tools needed for regular
maintenance.
• Allen Keys (hexagonal): 3 and 4 mm.
• Torx Key: T25
• Screwdriver: Philips 1 or Pozidrive 1.
4.2 Maintenance planThe inspection intervals given below are for a “typical”
application. The correct interval depends on the amount
of dust and dirt pumped through the venturi. You will
have to make up your own maintenance schedule based
upon your own experience.
Details of each maintenance point are described under
the respective headline below.
* Inspection interval for the Evacuation, Fill and Test Port 2 valves depends greatly on the amount of particulates
in the objects tested. Metal burrs and other sharp particles will wear the valves down, requiring shorter maintenance
intervals.

Replace or clean valves when necessary.
Use the Hardware Test function to check condition of valve.
Replace or clean valve when necessary.
Set PLC in STOP position, remove output hose from load
side and block with finger. Change valve if pressure builds.
Check sensitivity and response time. See manual for H2000
PLUS and/or active probe used.
34 Adixen Sensistor - Technical Manual ILS500
You can install a particle filter between the Test Port
and the object to prolong maintenance intervals. Be
aware though that this will result in prolonged cycle
times and higher tracer gas consumption.
** N.B. The gas sensor check in the maintenance plan
can not replace the regular sensor calibration. Sensor
calibration should be carried out typically every day as
part of the total test system self check.
4.3 Venturi PumpThe Venturi pump is a simple single stage device without
valves or other moving parts. It will not normally wear
down and will therefore not need to be replaced.
It can, however, collect dirt and dust and gradually lose
capacity.
If this occurs it must be removed and cleaned.
4.3.1 Cleaning/replacing the Venturi Pump
1) Remove the Exhaust hose from the barbed hose fitting.
2) Unscrew and remove the barbed hose fitting and the
plastic washer.
3) Use a T25 key to remove the two screws holding the
side cover (next to gas ports).
4) Slide the cover back and lift it off. Rock the rear end
of the cover up and down a few times to loosen.
35Adixen Sensistor - Technical Manual ILS500
5) Use a 4 mm Allen key to remove the four screws
holding the Venturi pump.
6) Remove the o-ring under the Venturi. Re-move the
hose from the Venturi inlet.
Push hose into connector and press orange ring down
to release hose, then pull hose out.
7) Remove the hose fitting from the Venturi.
8) Install new Venturi or use compressed air jet and a
cotton bud, pipe cleaner or small brush to clean the
nozzles inside the Venturi.
9) Replace hose fitting on Venturi inlet.
10) Reconnect inlet hose.
11) Clean o-ring and install in groove on valve manifold.
12) Reinstall and tighten the four screws.
13) Put plastic washer inside Venturi outlet and reinstall
barbed fitting. Tighten with spanner.
14) Reconnect the exhaust hose.
15) Run through the hardware test again to test that the
Venturi delivers adequate max vacuum.
36 Adixen Sensistor - Technical Manual ILS500
4.4 Gas Valves
1) Use a T25 key to remove the two screws holding the
right hand cover (next to gas ports)..
2) Slide the cover back and lift it off. Rock the rear end
of the cover up and down a few times to loosen. See
above.
3) Use a 3 mm Allen key to remove the four screws
holding the valve to be changed.
4) Lift the old valve out.
5) Put the new valve in. Notice the correct orientation in
the picture above.
6) Tighten the screws 2-3 mm at a time moving the key
from screw to screw so that the valve doesn’t tilt much.
7) Tighten the screws and replace the cover.
8) Run through the hardware test again to test that the
changed/renoved valve(s) perform as required.
9) Use hand probe to check that there is no external
leakage (this part of Hardware Test is routine).
37Adixen Sensistor - Technical Manual ILS500
4.5 Pilot Valves
1) Use a T25 key to remove the two screws holding the
right hand cover (next to gas ports).
2) Slide the cover back and lift it off. Rock the rear end
of the cover up and down a few times to loosen. See

the valve. You must back the screw all the way out until
you feel it “jumping” in the thread entrance.
4) Push down on the LEDs while pressing the screw
down until you feel the locking mechanism
“snap”.
5) Lift the old valve out from the coil side. If the valve
does not come off, repeat steps 3 and 4 making sure the
screw is completely backed out.
6) Push the screw in while inserting the new valve. Insert
the end facing the screw first and then push the coil side
down.
7) Tighten the screw.
