Preamble

3. THE MAIN TYPES OF MEASUREMENTS The are two main measurement methods that can be performed by the ATEQ F420P, direct measurement or indirect measurement. These two methods apply to measurements taken both under pressure and in vacuum conditions. The configuration is determined by the application and must be carried out prior to the use of the instrument. 3.1. DIRECT/PRESSURE DROP MEASUREMENT After filling the test part to the required pressure level, the instrument measures the drop in pressure. At the end of a cycle, the ATEQ empties the components via the dump valve. 3.2. INDIRECT/PRESSURE RISE MEASUREMENT The test part is placed in a sealed bell and the ATEQ F420P is pneumatically connected to the bell. The part is externally pressurised (with up to 20 MPa or 200 bar), and the bell is lightly pressurised. In the event of a part leakage, the pressure in the bell will rise. This method allows certain parts to be tested at high pressure levels whilst avoiding the associated constraints. The ATEQ F420P only tests and measures the pressure in the bell. In the event of a large leak, electronic monitoring of the pressure in the bell will switch the instrument to safety.

The wait time

The time during which the sealing connections are made to the test parts before the part is filled. The instrument may be fitted with the optional automatic connector (this option adds an extra valve). This valve is controlled for the duration of the cycle to enable the installation of the expandable joint connectors to be checked.

The fill time

Pressurisation of the test part. At the end of the fill time, the ATEQ instrument checks the test pressure. If this is not correct, the instrument will signal a test pressure fault.

The stabilisation time

The test part is completely cut off from the air supply, but remains pressurised to the test pressure level. Pressure and temperature will then stabilise between in the part. If the test pressure is incorrect (a large leak), the test pressure will drop rapidly, the instrument will not move on to the test mode and will indicate a fault.

Time during which the pressure sensor measures the changes in The test time pressure in the test part. The signal is electronically assessed and displayed, the part is then diagnosed as good or bad. The dump time

Return of the part to the atmospheric conditions.

Cycle end

Once the dump has been carried out, the instrument emits a cycle end signal and the automatic connector valve (optional) is deactivated. This valve can control one or more expandable connectors from the beginning to the end of the cycle.

Chapter 1 – Installation of the instrument 2.2.2. 4) Pneumatic supply

Air is supplied via the filter located on the rear panel of the instrument. Note: when an electronic regulator is used with test pressures above 800 kPa (8 bar) (normal service pressure), another "high pressure" input for the test circuit is installed on the instrument. It is essential that the air supplied is clean and dry. Even though there is a filter, supplied with the instrument, the presence of dust, oil or impurities may cause a malfunction. When the instrument is working in vacuum conditions, impurities must be prevented from being drawn into it. For this purpose we strongly recommend that a suitable airtight filter is installed between the test part and the instrument. This filter can be supplied by ATEQ. The presence of impurities, oil or humidity in the air may cause deterioration which will not be covered by the guarantee. In accordance with ISO standard 8573-1 concerning classes of compressed air for measurement instruments in an industrial environment : ATEQ recommends : • Grain size and concentration

CLASS 1

(0.1 µm and 0.1 mg/m3)

• Dew point under pressure

CLASS 2

(- 40° dew)

• Maximum concentration of oil

CLASS 1

(0.01 mg/m3)

ATEQ recommends the installation : • of an air dryer to provide dry air at less than - 40° dew point, • of a 25 micron and 1/100 micron double filter. Optimisation of operation : The supply pressure must always be between 4 and 8 bar to ensure that the pneumatic distributors operate with optimum efficiency. When a mechanical regulator is used, the supply pressure must be a minimum of 100 kPa (1 bar) greater than the test pressure with a minimum of 400 kPa (4 bar).

_

+

Two rapid connectors may be mounted on the front panel of the instrument. These enable pressure and calibration to be checked easily. The first is used for the regulator circuit. It enables the value of the test pressure shown by the instrument, measured with a pressure gauge or the ATEQ Leak/Flow Calibrator (CDF), to be checked. This connector is not part of the measurement circuit and cannot therefore interfere with the control. The second is used to check the test circuit and enables, by use of a calibrated leak expressed in cm3/min or another unit, calculation of the equivalent drop in pressure and, if required, calibration in this unit. As this connector is part of the measurement circuit, all its connections must be air tight.

2.2.1. Leak test The leak test is most suitable for measuring small leaks (pressure drop). The following formula is used to convert a leak expressed in units of flow to a drop in pressure F (cm 3 /min) ∆P (Pa/s) = 0,0006 x V (cm 3 ) F(cm3/min) 0.0006 V (cm3) ∆P (Pa/s)

Chapter 3 – Start-up and settings 2.2.2. Blockage test mode The blockage mode is used for rough measurement of a flow, based on measurement of back pressure. The standard pressure limits are used to classify the result as good or bad. The cycle only contains the fill phase and the reading is carried out during this phase. If the pressure measured is below the minimum limit, then the flow is too large. If the pressure measured is in excess of the maximum limit, then the flow is too small.

2.3.1. Coupling time Coupling times A and B are start of cycle parameters. If there is no automatic connector, Coupling time A is part of the cycle. If an instrument is fitted with an automatic connector, Coupling time A delays the pressurisation of the test part by allowing the activation of a first cycle connector at the test start. Coupling time B allows the activation of a second automatic connector. These Coupling times ensure better stabilisation of the seals placed on the test part. )Set this parameter using the method described in § 2.3.

Chapter 3 – Start-up and settings 2.3.2. Fill time This is the time allowed for the pressurisation of the part to be tested. It must not be too long (waste of time) or too short (the pressure in the component is at risk of not being sufficient due to drops in pressure caused by temperature changes). To determine the appropriate fill time, it is necessary to set the Fill Time in order to make it Too Long (TTLR), then to shorten it until a drop in pressure occurs due to thermal effects. Determine the TTLR by using the following formula: TTLR = 4 volume in cm 3 x test pressure in mbar 9 Carry out a cycle. When the instrument switches to the stabilisation period, the pressure must remain stable. 9 A pressure drop (since there will be no fall in pressure due to thermal effects) signifies the presence of a large leak; check the test part and the pneumatic assembly components, then start again. 9 If the pressure remains stable, the part does not contain a large leak and the fill time is too long. Shorten it progressively by carrying out cycles until a drop in pressure is noticeable. 9 As soon as a fall in pressure due to thermal effects appears, the fill time has become too short. Increase it slightly. )Set this parameter using the method described in § 2.3. 2.3.3. Stabilisation time This time is used to stabilise the pressure in the test circuit. It is possible that a change in pressure occurs due to thermal exchanges between the components. If the instrument takes a measurement too early, the instrument will indicate the presence of a large leak. 9 To determine the correct stabilisation time, it is necessary to set a long time so that the reading at the end of the test time is equal to zero. 9 Set the stabilisation time to four times the length of the fill time. 9 Carry out a cycle. When the instrument switches to the test period, the pressure must remain at zero. 9 If there is a drop in pressure, there is a small leak present. Check the test part and the pneumatic connections, then start again. 9 If the pressure is stable, the part does not contain a small leak and the stabilisation time is therefore too long. Progressively shorten and carry out cycles (wait one minute between each cycle) until you see the appearance of a drop in pressure. This indicates that the stabilisation time has become too short. Increase it slightly. )Set this parameter using the method described in § 2.3.

User manual ATEQ F420P Page 25/74

Chapter 3 – Start-up and settings 2.3.4. Test time The test time depends on the programmed reject level and operation mode. In the dP/dt (Pa/s) mode, the variation in measured pressure is due to the drift in the pressure drop. In the dP (Pa) mode, the pressure variation measured is the total of the pressure drop over the whole test time. This mode is more unstable, but is more sensitive. The instrument totals all the variations occurring due to variations in volume or temperature over the whole test time. )Set this parameter using the method described in § 2.3. 2.3.5. Dump time The instrument will as default propose a dump time of zero. This must be set by carrying out several tests. )Set this parameter using the method described in § 2.3. 2.3.6. Pressure units The different units are bar, mbar, PSI, Pa, kPa, MPa. . ) Set this parameter using the method described in § 2.3. 2.3.7. Maximum fill This function is used to set a maximum limit for the fill pressure. A warning is triggered if this limit is exceeded. When test time is infinite, the maximum fill pressure monitoring is inoperative. Care should therefore be taken to avoid excess pressure being applied to the part during the test. . ) Set this parameter using the method described in § 2.3. 2.3.8. Minimum fill This function is used to set a minimum limit for the fill pressure. A warning is triggered if this limit is not reached. . ) Set this parameter using the method described in § 2.3.

Chapter 4 – Functions of the instrument 2.1.3. 4) ATR (Transient attenuation) An ATR cycle enables time to be gained over a traditional cycle by enabling the stabilisation time to be reduced and absorbing the transient pressure. The transient pressure is an unexpected drop in pressure caused by a stabilisation time which is too short. The ATR may require a « learning » cycle to enable the transient pressure to be measured. As the transient can evolve both negatively and positively, It is preferable to maintain identical Test and reference reject levels. a) ATR 0 The initial value of the transient is known. Parameters must be set manually. The ATR may only be used on parts which have identical behaviour during the test, in other words, parts which have an identical transient. Associated parameters to be set: Initial (Initial value of the transient), Transit (actual, non modifiable value of the transient), Tolerance (Drift tolerance on acquisition of the transient, % of the reject level). ) Select the option and enter settings if necessary. b) ATR1 The value of the transient is unknown. A special learning cycle must be carried out. Associated parameters to be set: Initial (Initial value of the transient), Transit (actual and non modifiable value of the transient), Tolerance (Drift tolerance on acquisition of the transient, % of the reject level). ) Select the option and enter settings if necessary. c) ATR2 Corresponds to ATR 1 but the potential leakage of the part is taken into account when the value of the transient is determined during the special cycle. Associated parameters to be set: Initial (Initial value of the transient), Transit (actual and non modifiable value of the transient), Tolerance (Drift tolerance on acquisition of the transient, % of the reject level). ) Select the option and enter settings if necessary. For ATR learning cycles, see paragraph 3.6. "ATR learning". When a parameter is modified but no learning cycle has been carried out, an "ATR" fault occurs. The "alarm" and "end of cycle" outputs are activated. Learning may be carried out on a value greater than the reject level and the "Pass" and "end of cycle" outputs are then activated. However, the "ATR" fault appears if the difference between the transient and the initial value is greater than the reject level.

CAL Learning (calibration) If the 4 units of flow are not appropriate for the application, it is possible to go to calibrated mode (manual). To do this, a learning cycle must be carried out so that a calibration value will correspond to a pressure drop. To access this special cycle, select the unit Cal-Pa or Cal-Pa/s as a reject unit when creating a program (for selection of units, see chapter 3 § 2.3 "Setting parameters"). Then the special learning cycle must be carried out, either from the special cycles menu or from input 7 on connector J3 programmed for this function, or via a programmed function key on the optional RC5 keypad, if this is installed. The first CAL learning cycle must be done using the special cycles menu so that a CAL target which is different to zero can be entered. On these outputs we have: ¾ "Pass" and "end of cycle" if the target is lower than or equal to the test reject level, ¾ "Fail" and "end of cycle" if the target is greater than the test reject level. In the main menu, place the cursor in front of the SPE CYCLE function and confirm using the ENTER key.

Chapter 5 - Accessories 2.2. NEEDLE VALVE AND LEAK/FLOW CALIBRATOR (CDF) 2.2.1. Needle valve Needle valves are used to calibrate the leakage limits. These valves have an adjustable leak and depending on the model allow adjustments of between a few cm3/h to several l/min. These valves can be easily disturbed and therefore require the frequent use of some means of checking the setting (eg : SAGA 4000). Note: it is strongly recommended that you do NOT leave a needle valve permanently connected on a leak detection machine with automatic calibration every « n cycles ». 2.2.2.

2.3. AUTOMATIC CONNECTORS WITH EXPANDABLE JOINTS ATEQ automatic connectors are used so that accurate and reliable assemblies can be built to check air tightness. They simplify the work of the operator as they are selflocking thanks to the use of a pneumatic valve supplied from the mains compressed air supply. Several connectors may be controlled by the same remote, powered by an ATEQ or another logic. They adapt easily to a large number of fittings and apertures of varied dimensions. Their use ensures that non-machined walls can be guaranteed airtight. There are four basic versions of ATEQ automatic connectors : 9 SA for external connections, 9 Si for internal connections, 9 SAG and SIG for threaded and tapped connections. They are either in anodised aluminium or stainless steel as standard. Different types of joints are available depending on the elasticity required. 2.3.1. Operation The connector is positioned manually or automatically using a jack or cylinder. Compressed air is allowed through the control aperture via a three part valve. The pressure pushes the cylinder which squashes the connector. The air tightness is therefore perfect and there will be no leakage in the connector seals. 2.3.2. Standard dimensions SAG and SIG have been designed for threaded and tapped caps. For the time being, they are available in gas norm. Sizes, which are: 1/2", 3/4", 1", 11/4", 11/2", 2", BSP. The SA and SI are designed for smooth nozzles, with dimensions from 3 to 80 mm for the external diameters (SA), and from 10 to 75 mm for the internal diameters (SI). 2.4. FILTRATION KIT Clean, dry air must be used to ensure the reliability of the instruments. The filtration kit is connected to the air input on the rear panel of the instrument. It consists of a dust filtering cartridge (5µm) and another cartridge (0.01 µm) giving residual oil pollution equal to 0.01 ppm.

Chapter 6 – Error messages PROBLEM or CAL drift found following request for CAL check. Action: check the programmed percentage of CAL drift, the known standard leak and the test pressure. Commutation fault in the equalising valve. Action: check network pressure, contact ATEQ after sales service for repair. 1) The electronic regulator has been unable to initialise correctly. 2) The input pressure on the regulator must be at least 10 % of regulator full scale + 100kPa (+ 1 bar). Action: check supply network pressure or pressure at the regulator input. PROG error: the I/O's have selected a program with no parameters. Action: enter program parameters. Inappropriate size for the selected unit of pressure. Action: change unit or modify the minimum and maximum pressure limits if these and the test pressure can be used with this unit.

Chapter 7

OPERATIONAL PROBLEMS 1. PHENOMENON NOTED If a test machine begins to detect too many bad parts (statistically, more than three consecutively), it is advisable to carry out a check on the whole unit. The quality of the manufacture and operation of the leak detector should be the last things considered. 1.1. CONDITION OF THE MACHINE'S SEALS This is the no.1 defect as the seals are subject to high levels of dirt contamination (alumina, shavings). Regular cleaning of the seals is an effective remedy. 1.2. DAMAGED INSTRUMENT SEALS There is a possibility that the seals may be cut by shavings or worn by repetitive squashing. This can be prevented by regular servicing and replacement of the seals. 1.3. BUMPER PAD This is a defect which may occur after a certain amount of time as the bumper pads may be worn, or if the pressure settings in the air cylinder are inadvertently disturbed. Check the stability of the measurement and that the bumper pads are correctly installed. 1.4. PNEUMATIC AIR SUPPLY TOO LOW This anomaly can cause false measurements (large leaks or erratic measurements). The air supply to the cells must be higher than the minimum of 4 bar and it is essential that it is greater than the minimum test pressure of 1 bar. Also check that sealing connectors are being used correctly. 1.5. PNEUMATIC LINK The link and reference pipes will age and break with time. The pipes and seals must conform to the required quality. ATEQ recommends the use of RILSAN PA11 pipes and AVS type joints.

Chapter 7 – Operational problems

1.6. ENVIRONMENT A measurement may be affected by a variation in background temperature (sun, draughts, storage of parts outdoors, handling of the test part by the operator, ...). The dampness of parts may cause errors in the readings (insufficient drying after washing, outdoor storage, condensation, presence of water in the fixture, ...). 1.7. CALIBRATION ATEQ does not accept any liability in regard to calibrations and settings to its instruments which are not carried out by its own personnel. 1.8. CONCERNS ABOUT RELIABILITY OF THE INSTRUMENT’S CIRCUITS If all the other checks do not resolve the problem, the instrument’s circuit may be checked. Proceed as follows : 9 Segregate the instrument from its environment (pneumatic assembly), 9 Connect up the instrument (test output), 9 Choose an unused program, 9 Set the parameters as follows : ⇒ the regulator

to the test pressure,

⇒ the pressure monitoring thresholds

to +/- 20 % of the test pressure,

⇒ wait times A and B

0 seconds,

⇒ fill time

4 seconds,

⇒ stabilisation time

10 seconds,

⇒ test time

10 seconds,

⇒ dump time

⇒ reject level

⇒ unit
