INSTALLATION INSTRUCTIONS INSTALLATION INSTRUCTIONS

Air leak testers detect leaks by reading out precise pressure (air condition) alterations. Thus, it requires different handling instructions from other standard precision equipment.

WARNING

Tester must be in a stable position. ・Be sure to install the tester on a level surface.

Vibrations or earthquakes may cause the tester to fall and cause injury to operators. Do not place anything on top of the tester. ・Do not place anything on top of the tester. Falling objects may

result in injury.

CAUTION

Do not install the tester in the following locations: ・High moisture or dusty areas. ・Areas in which oil and water can cause contamination. ・Areas directly exposed to sunlight. ・Outdoors

May result in fire or electric shock. ・Areas with obstructions or places in which the testers fanning

system may be blocked. The tester may overheat and may cause for fires. Moving the Tester: ・ Be sure to shut off the power, unplug cords, cut off the

pneumatic source and remove piping. ・Be sure to carry the tester in a stable manner. (Do not carry the tester by the manual valve handle.) May cause damage to the tester or to its casing and may result in injury.

OPERATION ENVIRONMENT

FL-286,296

14

FL-286,296

• To keep the stable measurement condition, install the air leak tester where it will not receive any influences from temperature or humidity changes, such as at the center of the facility. Do not install the tester near windows or an area that is directly exposed to the sunlight. The operation temperature and humidity is as follows. Ambient Temperature: 0~40

Ambient Humidity: 35~85%RH with no condensation.

• In order to attain best results and accuracy, it is recommended that the operation temperature and environment humidity condition is 23 ±5, 55±10%RH.

• Rapid temperature change adds the noise on the measurement and specified performance cannot be obtained.

• Transferring the tester rapidly from high to low temperature locations and/or humidity points may cause condensation. When such cases cannot be avoided, leave the tester in the environment for at least an hour in order for it to adjust to the surrounding temperature.

• Environment Temperature change is the enemy of leak test. Avoid the direct sun shine or the wind from outside on work, master and measurement piping. Also be careful against the wind from air conditioner (heating/cooling) duct or the entrance.

AIR PIPE CONFIGURATIONS Air leak testers are designed to detect a leak by sensing a small change in pressure. For that reason, you must ensure that the air leak tester’s piping differs from normal piping. Please keep this in mind to help obtain accurate and reliable leak testing. TEST CIRCUIT PIPES For the test circuit piping, it is necessary to use rigid, leakless pipes that will not change in size and

configuration under applied pressure. For connection, use a high-pressure type coupler.

Arrange them to minimize thermal effect. Keep them away from heat generating elements such as solenoid valves. Keep the piping arrangement as short as possible. Wrap them with thermal insulation material. (e.g. Spiral Tubes） Others Stabilize the piping to avoid unnecessary movements during measurement. Allow “MASTER” and “WORK” piping to provide the same conditions. Do not connect inappropriate items to the testing piping.

Make sure you always use the optional pressure switch which checks the internal pressure of the work, if the equipment is used with a pressure of 10 kPa or lower.

IN CASE OF WATER/OIL INTRUSION IN WORK

Oil, water or chippings may intrude in works because of the previous process.

The tester may draw in unwanted objects during the exhausting process, and may cause possible break down. Install the external exhaust unit (optional) within the testing air circuit. While the FE-20 optional external exhaust unit is in use, close the exhaust port of the air leak tester with the attached plug.

COMPRESSED AIR SOURCE: Water and oil intrusion often cause the pressure sensor in the air leak tester to malfunction. Be sure to provide an air filter, and if necessary, equip an air purifier such as an air dryer. Furthermore, it is important to contrive a bypass air piping system when using lubricator so that lubricating oil will not intrude the tester

CLAMPING EQUIPMENT Regulators to adjust the cylinder driving pressure must be provided separately for each cylinder. This minimizes the possibility of cylinder movement, which destabilizes the pressure supply to the air leak tester. Supplied air pressure fluctuation may interfere with the clamping powers of the other cylinders

KEEPING THE INTERNAL VOLUME AS SMALL AS POSSIBLE In order to increase test sensitivity, keep the internal volume of the work and master parts as small as possible. Shortening pipes or using a core is ways to decrease internal capacity.

AVOID TEMPERATURE CHANGEIn order to avoid temperature interference to work parts waiting to be tested, keep them close to leak tester and at about the same level.

PREPARE THE MASTER PARTS It is recommended to use master (criterion) parts for air leak testing. Leak testing accuracy will change according to the status of the applied master parts, so it would be ideal to use master parts equivalent to the work parts in shape, material, piping and mounting. Maintaining these conditions can be difficult in actual settings. Please refer to the following chart when choosing a master part.

Best Method Alternative Master ･Test Parts with no leak

(same conditions as the work) ･A rigid tank that has a slightly smaller volume than that of the work (to stabilize quickly)

Mounting Position

･Same height from the ground as the work ･Near the work

･Same height as the work and surround the peripheral ･Environment with the same temperature interference conditions as the work parts

Piping Arrangement

･Same conditions and arrangement as the work piping and arrange piping in plane .

･Same piping length as the work port (shorter when there is temperature interference)

Select appropriate wires and material according to use, considering voltage and current requirements for each of the terminal outlets located on the rear panel of the tester. To avoid noise interference, run the input signal lines separately (pins #1 to #12 of the Terminal Board)

from the output signal lines. To avoid noise interference, run the input signal lines separately from other power supply lines. To avoid noise interference, it is recommended to use a shield wired for input signal lines. Be sure to ground the frame grounding (pins #37 and #38 of Terminal Board). Use an insulated transformer when the power for the tester is supplied through a step-down

CONNECTING THE EXHAUST BYPASS UNIT (COMPRESSED AIR PRESSURE MEASUREMENT)

Air Leak Tester

In the figure above, → implies “open to atmospheric pressure” The branch to the exhaust bypass unit (①) should be placed as close to the WORK parts as possible. For WORK—WORK comparison measuring, the exhaust bypass circuit must also be provided for the

WORK parts on the Master side port. Measurements, on occasion, can become unstable due to an unbalance caused by the exhaust bypass unit

only being provided to the WORK side. For such cases, provide an additional exhaust bypass circuit for the MASTER side to establish a balance.

While the FE-20 exhaust bypass unit is connected, calibration with WORK parts application becomes impossible. As a substitute procedure, carry out a normal test with atmospheric pressure as the test pressure.

CONNECTING THE PRESSURE VERIFICATION SWTICH

Air Leak Tester

The figure above is applied to connections when measuring under positive pressure. In the figure above, → indicates open to atmospheric pressure. The pressure verification function ensures leak tests are conducted under the specified pressure.

Site ① is to verify the TEST pressure, and site ② is for WORK pressure verification. This function also allows checking the status of the WORK PORT manual valve. However, it may cause testing instability. For WORK pressure verification, consider the following;

・Do not use a mechanical pressure switch with large operation displacement. ・Use a durable switch. (The switch will be operated twice for each testing).

・When using a semiconductor pressure switch, contrive a piping system to avoid liquid intrusion. When using a semiconductor pressure switch, connect as follows.

If you decide to use your own pressure switch, ensure that it satisfies the following specifications.

CONNECTING THE MANUAL VALVE STATUS VERIFICATION SWITCH

This function is designed to verify the status of the MANUAL VALVE (OPEN/CLOSE) by using the pressure verification function. An error will be indicated as “P.NG”. Connect the wires as described as below when using this function together with the pressure verification function.

DRIVING EVALUATION INDICATOR

The external alarm lamp is illuminated by the Air Leak Tester evaluation signal. The example shown above is the connection to light Green lamp for OK (accepted), and Red lamp for +NG、－NG、P.NG (rejects and error).

The load capacity should be kept within the rated value（Rated load: AC 125 V 0.4A DC 30V 0.4A） When connecting to the direct voltage to output signal line, and the relays and other devices are malfunctioning,

provide a resistance in the circuit as shown in the diagram below. The Remote terminal output is equipped with a noise suppressor, and it may generate a leak current when it is turned off (Estimated leak current: 3mA Max for AC100V 60Hz)

EFFECTIVE USE OF A CORE

As you may already know, leak detection through air leak testing is based on the principle that pressure is reduced when there is a leak. This implies that even if there is the same degree of leak, depending on the internal volume of the tested works, the pressure reduction rate will also vary. In other words, if the internal volume were smaller, the pressure reduction rate would be greater; therefore, testing precision and stability would increase. When it is possible, it is recommended to insert a core into the work. A core is a devise that decreases the internal volume within the work. It should be made of a material that will not leak and not change its shape and volume by the test pressure.

“THE CLEAN-UP TRIO “Okay, the compressed air source for the air leak tester must be clean. So, I think I will use the Clean-Up Trio”. Wait a minute! Oil intrusion is one of the major problems for an air leak tester. Please do not use a lubricator!

IS TEMPERATURE AN ENEMY?

As previously mentioned, the air leak tester uses pressure reduction rates to conduct leak testing. However, temperature and rate changes easily influence pressure. Perhaps the leak testing time is not very long so it may not be necessary to be extremely cautious about this issue, but it may be wise to pay some attention to the precautions.

① Are Hot Water Wash, Quenching or Welding processes performed prior to the leak testing procedure?

If there are, cool down the work before conducting the leak test, or reconsider the formation of the process line.

② Are the works to be tested sensitive to temperature? Are they designed or produced for the purpose of

good heat conduction such as oil coolers, and radiators? These types of works receive a great deal of influence from even weak drafts, and testing accuracy will be affected. In such cases, provide a draft shielding to cover the work-clamping portion of the system. This also provides protection for the operator from accidentally clamping their hands.

③ It is recommended to keep the works at the same level as the tester. When works are stored at low

levels, such as the floor, while waiting their turn for testing, they may become too cold for the testing process. Keep them at the same level as the tester and maintain a stable temperature to improve testing accuracy and attain desirable results.

output is right-aligned, and 20h represents blank digits. Example: 12.3 sec; 123. 1.0sec; 10 (where a represents 20h)

＊ The settings data is also expressed without a decimal point. If you have an NG error, a (-) will precede the value.

Example: If you get an –NG error on the FL-286, -1.00kPa; -100 (It is assumed that the 2 digits beyond the decimal point are fixed on the FL-286).

＊ Your input data should be within the machine’s possible setting range. If you attempt to send data outside of the range, all data is destroyed.

＊ If CHG1 is not specified, the CHG1 process time is assumed to be 0sec and the data length does not change.

(3) The air leak tester saves transmitted data. The data is written into an EEPROM and saved. ＊ The possible data transmission time depends on the number of times the EEPROM can be

rewritten, therefore transmission data cannot be saved after one million transmissions. ＊ If you get a P.NG error, there are two possible values: +0 and -0. “+0” is written as “0” and “-0” is

written as “-0”. ＊ The –NG (leak amount) and test data units used on the leak amount display unit is as follows.
