Overview

Parker Hannifin’s ACM20.2032 is a Laser Particle Counter. This battery operated, aviation fluid contamination measurement instrument is designed for use in ATEX category 3 areas and is made up of two parts, the main unit and a hand-held controller.

The main unit consists of a Ex e enclosure, which is protected by restricted breathing and has a hinged lid to cover the controls. Mounted on the top of the enclosure is an ITW Series 57 miniature vandal-resistant switch to turn the unit on and off, a valve control knob which is attached to a link shaft passing into the enclosure and two connectors, one 3-pin and one 8-pin. Lanyard mounted covers allow for battery charging and data transfer in non-hazardous areas.

With the lid closed, the enclosure measures 305mm tall x 200 mm deep x 330 mm wide. Two hoses passing through Lapp skintop cable glands on the left-hand side of the enclosure allow for fluid to be transferred in and out for analysis. On the base of the unit is a restricted-breathing test point.

The hand-held controller is protected by energy limitation and measures 175mm long x 95mm wide x 30mm deep. It is connected to the main enclosure via two Lapp skintop cable glands and a spiral wound cable. It has a 16-button keypad and a 55 x 55 mm LCD screen.

Interpreting data

Solid contaminants in aviation fuel systems vary in size, shape, form and quantity. The most harmful contaminants are normally between 6 microns and 14 microns. The ISO code is the preferred method of reporting quantity of contaminants.

The ISO code number corresponds to contamination levels pertaining to three sizes.

The first scale number represents the number of particles larger than 4µm(c) per 100 millilitre of fluid, the second number for particles larger than 6µm(c) per 100 milllilitre of fluid and the third number for particles larger than 14µm(c) per 100 millilitre of fluid.

Below is a table of actual results obtained, of contamination within a hydraulic pump endurance test rig.

Measurement accuracy

Calibration

Every monitor is individually calibrated using an accurately determined gravimetric level of test dust media.

Each channel within the instrument is adjusted to read the number of particles in a prescribed size range as specified in ISO procedures, thus guaranteeing calibration accuracy.

Repeatability

The ACM20.2032 measures and quantifies individual particles using advanced electronics and laser technology to ensure a high degree of repeatability.

Repeatability is typically better than 5%.

Diagnostic codes

Explanations of ACM20.2032 diagnostic codes are given in the following table.

Diagnostic 1

1A. At beginning of test (the first two segments showing)

Fuel is too dark or it is cloudy. Check sample of fuel visually. This can be done as follows:

Dark fuels: Wet your thumb and forefinger in the fuel and press together. Release and look at your thumb. If you can see through the film of fuel it should work in the ACM20.2032. If you cannot, then you may have problems.

Emulsions: Put sample in a clear container and hold up to the light. This will show cloudy or clear. If cloudy, check the type of fuel and change until the fuel is clean. Then retry ACM20.2032.

1B. at the end of the test

Unstable fluid opacity may be caused by aeration, water sludge or an amount of cold fuel passing through ACM20.2032

Allow machine to work up to operating temperature before performing condition monitoring. Run tests with a stable system and ensure that a minimum line pressure of 2 bar is available at the monitor to reduce the possibility of aeration.

Diagnostic 2

The changeover valve and syringe pump are out of phase

a. Control knob turned, either before monitor switched on, before valve symbol displayed on handset or during a test

b. Time taken to turn valve fully to next position is too long (20 seconds)

c. Microswitch setting fault.

a. Switch off the monitor, then switch on and wait for monitor to reset its position (diagnostic screen 6 is displayed). Start next test when valve symbol is displayed on handset.

b. Return to Parker Hannifin for repair

c. Return to Parker for repair.

Diagnostic 3

Uncontrolled power down

a. Battery power too low. Battery level warning ignored

b. Internal electrical fault

a. Charge the unit (outside the hazardous area) b. Return to Parker Hannifin for repair

Diagnostic 4

Insufficient flow rate of fuel from P1 hose into monitor block to fill syringe pump.

Results are suspect and not made available.

a. Inadequate differential pressure across P1 and P2 connections to provide sufficient bypass flow.

b. Air lock in monitor block or blockage in bypass hoses.

i) Select smaller sized sensor

ii) Use a Single Point Sampler connected to P1 (see the Parker Hannifin catalogue for details). Purge by using system pressure with P2 hose disconnected from system.

REFERENCE


g

32

Diagnostic 5

Test time too short or too long.

Results are suspect and are not made available.

a. Malfunction of Opto-Tacho control, causing flow to stop before particle counting phase completed. Pump drive slipping or failed.

b. DP (Differential Pressure) too high due to lack of control of flow through ACM20.2032.

a. Care should be taken to allow fuel to discharge safely and should only be performed by a competent operator.

Re-test and if fault reoccurs, return monitor to Parker Hannifin for repair.

b. Use SPS (Single Point Sampler) or sensor to control flow through ACM20.2032.

Diagnostic 6

��

Unit trying to reset from last error

Displayed after switching on, while monitor is resetting itself from the previous error condition.

Leave it alone until it has reset.

If it does not reset, or switches itself off, contact Parker Hannifin.

Diagnostic 7 and above

These are faults which can only be rectified by Parker Hannifin and are normally software related

Displayed if the monitor block has reached a temperature above 60°C.

Remove ACM20.2032 from system connections.

Allow to cool down.

If unit does not reset, contact Parker Hannifin.

Low battery

��

Battery low. Recharge unit (only outside of hazardous area with the unit switched off).

Battery too low to complete a measurement. Recharge unit (only outside of hazardous area with the unit switched off).
