Powering the icountLCM20The icountLCM20 may be powered via:

a re-chargeable battery pack. This is supplied as an accessory with its battery charger – see ■■‘Ordering information’ on page 49.

a replaceable battery pack. The battery compartment requires six LR20 ALKALINE batteries. ■■LR20 batteries are readily available and are also known as Type D or 13A batteries.

Charging the rechargeable battery packStep

1 Fully loosen the two retained screws and remove the rechargeable battery compartment.

Warning: Take care not to short-circuit the terminal plates.

2 To charge the unit, attach the flying lead of the 12Vdc supply to the input power socket of the rechargeable battery pack. The jack plug should be tip positive.

Attach the mains plug to a mains socket and switch on.

The red LED on the rechargeable battery pack flashes to indicate that the unit is charging.

3 When fully charged, the red LED remains steadily on.

Disconnect the 12Vdc supply, replace the battery compartment and refit the two screws.

Note: When the Particle Counter displays a Low Battery Warning, you should recharge the batteries immediately. Battery packs in storage or fitted to units should be recharged every three months. The capacity of the battery pack is severely reduced if batteries are left in a discharged condition for long periods.

Basic operationthe icountLcM20 is now ready to check the cleanliness of the hydraulic oil in your system. You can take readings at full working pressure (max. 420 bar).

NOTE: The icountLCM20 is supplied filled with hydraulic oil and may need to be flushed prior to use.

Step

1 Disconnect the hydraulic hoses from the ‘hose tidy’.

2 The icountLCM20 is designed for use in connection with System 20 size 0, 1 and 2 Industrial Sensors or the Single Point Sampler. The sensors have the following dimensions:

Size Diameter

0 30.0mm

1 41.0mm

2 66.7mm

NOTE: ‘Dual fluids monitors’ must be connected to a special System 20 Sensor or Single Point Sampler. See page 45.

3 Ensure that the Sensor is installed with the arrow matching the direction of flow.

Working viscosity is 2–100 cSt. Ensure a minimum working pressure of 2 bar

Reference

Data interpretationSolid contaminants in fluid power 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 4µ(c) per 100 millilitres of fluid, the second number for particles larger than 6µ(c) per 100 millilitres of fluid and the third number for particles larger than 14µ(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

CALIBRATIONEvery 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.

REPEATABILITyThe icountLCM20 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 codesExplanations of icountLCM20 diagnostic codes and possible remedies are given in the following table.

DIAGNOSTIC CODE 1a. At beginning of test

DIAG 1A. LIGHTSOURCE DEVIATION

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

Dark oils: Wet your thumb and forefinger in the oil and press together. Release and look at your thumb. If you can see through the film of oil it should work in the icountLCM20. If you cannot, then you may have problems. (This is most common with engine oils or very highly contaminated oils above ISO 24).

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 oil and change until the oil is clean, then retry icountLCM20.

b. at the end of the test

DIAG 1B. LIGHTSOURCE DEVIATION

Unstable fluid opacity may be caused by aeration, water sludge or an amount of cold oil passing through icountLCM20.

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 CODE 2The changeover valve and syringe pump are out of phase

DIAG 2. VALVEOPERATION ERROR

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.

Switch off the monitor, then switch on and wait for monitor to reset its position (diagnostic screen 6 is displayed).

Return to Parker for repair.

DIAGNOSTIC CODE 3Uncontrolled power down

DIAG 3. POWERINTERRUPTION

a. Power to monitor has been disrupted by removing power supply without switching monitor off.

b. Battery power too low. Battery level warning ignored.

c. Battery contact disconnected by excessive vibration.

d. External power supply connected (12Vdc) while unit is on.

Wait for monitor to reset itself.

Replace batteries with 6 x 1.5V Alkaline D Cells (or recharge battery pack if a rechargeable pack is fitted).

Relocate monitor on a sound surface (May also be hung from a carrying strap).

Leave unit to re-set itself.

DIAGNOSTIC CODE 4Insufficient flow rate of oil from P1 hose into monitor block to fill syringe pump.

Results are suspect and not made available.

DIAG 4. LOW FLOWIN BYPASS LINE

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

b. Air lock in monitor block or high viscosity slug of oil in bypass hoses.

i) Select smaller sized sensor

ii) Reduce viscosity of system oil by increasing test temperature where possible.

iii) Use Single Point sampler connected to P1. Purge the system pressure with P2 hose disconnected from system.

Care should be taken to allow oil to discharge safely and should only be performed by a competent operator.Re-test and if fault reoccurs, return monitor to Parker for repair.

REFERENcE


g

44

DIAGNOSTIC CODE 5Test time too short or too long.

Results are suspect and are not made available.

DIAG 5A. TESTTIME TOO SHORT

DIAG 5B. TESTTIME TOO SHORT

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

b. Differential pressure too high due to lack of control of flow through icountLCM20.

Use SPS or sensor to control flow through icountLCM20.

DIAGNOSTIC CODE 6Unit trying to reset from last error.

DIAG 6. LCM INRESET MODE

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

Leave the icountLCM20 alone until it has reset.If it does not reset, or switches itself off, contact Parker.

DIAGNOSTIC CODE 7 AND ABOVE

DIAG 7. REFERTO LCM20 SUPPLIER



All faults which can only be rectified by Parker and are normally software related.

DIAG 10. LASERTEMP TOO HIGH

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

Remove icountLCM20 from system connections and allow to cool down.

If unit does not reset, contact Parker.
