Up to 50 Test Groups may be configured, eac

17、h of which is identified by a User designated 3-character code. Every asset record contains a Group PAT4 should use when the appliance is tested. Each Group contains the following information: - Group Code:e.g. DRL Group name:e.g. Drills Voltage:230V or 110V Insulation Class:Class 1 = Earthed Class

18、2 = Double insulated. Tests to be applied: e.g.Bond test Insulation test Operation test etc. When setting up a Group, any of the PAT4 tests may be specified by placing a next to the selected tests. Note: The Earth leakage/touch current test is part of the Operation test enable the Operation test to

19、include an Earth leakage/touch current test. Asset Test Groups 20 For each selected test, PAT4 allows one of twelve pass band options to be selected. Earth Bond: Pass 50m, 100m, 200m, 300m, 400m, 500m, 600m, 750m, 800m, 1.0, 1.5, 2.0 Continuity: Pass 0.25M, 0.3M, 0.5M,1M, 2M, 4M, 5M, 7M, 8M, 10M, 20

20、M, 50M Operation: Pass 50VA, 100VA, 200VA, 350VA, 500VA, 700VA, 1000VA, 1200VA, 1500VA, 2000VA, 2500VA, 3000VA Earth Leakage: Pass 0.25mA, 0.5mA, 0.75mA, 1mA, 1.5mA, 2mA, 3.5mA, 5mA, 7mA, 7.5mA, 10mA, 15mA.

22、 not include an Operation test can be carried out using a 230V mains connection, and all Group tests for 230V assets which do not include an Operation test may be carried out using a 110V mains connection. An attempt to test an asset with an alternative voltage, when the test Group includes an Opera

23、tion test, will be inhibited, and the message “Test needs xxxV please change supply” will be displayed.

24、urrent: Pass 0.5M Save group to memory NOYES Add as a new group? NOYES 22 Assets Up to 1000 assets may be stored at any one time in the PAT4, each with their current and previous (Historic) test results. Appropriate asset details may be entered before or during testing. Once the asset record has bee

25、n set and stored, it never needs to be re-entered. The next time the asset is tested, only the asset ID number needs be entered or scanned, and the PAT4 will recall the complete record with the correct Group code and all the asset details. Testing follows automatically. This approach ensures that on

26、ce set up, there is no chance of the wrong tests being applied to the asset, as is possible with instruments that require a test code to be specified each time that an asset is tested. The Asset database contains the following details for each asset: Asset ID a unique code number (within a particula

27、r client), upto 10 characters long. For speed this may be scanned in rather than typed. Group ID a code (upto three characters) which identifies which test group should be used when testing the asset. Once again this code may be scanned in, if the tester has a prepared sheet with all the Group ID pr

28、inted as barcodes. Serial number to identify the asset precisely the serial number should be recorded this may be scanned in too (since many assets now have barcoded serial numbers on them). A maximum length of 15 characters is permitted. Asset description a description of the asset, e.g. Manufactur

29、er tears; cracks. Supply socket. Mains Plug. Environment e.g. operational hazards nearby. Mains Lead. Suitability i.e. used for correct purpose. On/Off Switch. Everything Else. 1 The test screen prompts the user to select either PASS or FAIL, if PASS is selected the test will progress onto the next

30、selected test in the group. 2 If FAIL is selected, then the screens will prompt to specify the nature of all the faults noted. 3 Press YES or NO to specify the Visual inspection failures. 4 Check for any hazards in the vicinity, e.g. asset is exposed to water. 5 Check asset is suitable for the task

31、it is being used for. 6. Any other hazards present. Note: - If an asset fails the visual inspection, no further tests will be performed and a repair code may be entered (see Repair Codes).

33、rity of the appliance earth conductor, high current (10A or 25A a.c.) is passed between the Earth Bond terminal and the appliance test socket earth pin. The current may be set to 10A or 25A (calibrated at 0.1). The PAT4 can store upto three separate earth bond test results for each asset test. The P

34、AT4 contains thermal overload protection, which may operate in extreme cases of repeated earth bond testing. The message “Bond test is too hot” will be displayed and the test will be aborted. Testing may recommence after a 10 minute cooling period. If this occurs frequently, refer to Settings and re

35、duce the Earth Bond test time. We recommend a duration of 5 seconds for this test. 1 Connect the bond lead to a suitable point on the asset under test. Press the OK key. 2 When the test finishes the final result is shown. If the result is OK, press PASS, then to store the result press LOG. If subseq

36、uent Bond tests are not required press the SKIP key when prompted to connect the Bond lead again. 3 If the Bond resistance is too high, press the FAIL key. If the asset has a long supply lead you can compensate the Bond reading to allow for this by pressing the COMP key. To fail the asset immediatel

37、y, press the LOG key. 4 Enter the lead length in metres. 5 Use the Up/Down keys to select the cross sectional area of the earth conductor. 6 The Bond Resistance is re-displayed taking into account the supply lead resistance. Press PASS or FAIL as appropriate. Earth Continuity Test This test provides

38、 a measurement of protective conductor resistance and is therefore applicable to Class 1 assets only. This test is usually applied to equipment which may be damaged by the high current Bond test (e.g. I.T. equipment). A low current (D.C.) is passed between the Continuity terminal and the appliance t

39、est socket Earth pin. The test current is limited to 200 mA with a maximum open circuit voltage of 4 V. To use this test the Continuity terminal and the black lead should be connected to the appliances exposed metalwork. On completion of the Continuity test, ensure that the black earth lead is disco

40、nnected from the appliance under test. The procedure for this test is very similar to the Bond test (some screen titles are changed). 10A Bond Lead Connected?

(Pre-Test) Prior to performing any of the main tests an initial check is performed to indicate an approximate value of appliance loop impedance. Abnormal results from this test displays a message indicating

42、the conditions that may affect the validity of the tests to be performed, or where possible damage to the PAT4 may result. When everything is in order, no message is given. The flowchart below shows the other possible displays. Open circuit - Check asset On/Off switch and /or fuse. Short circuit - C

43、heck asset before continuing. Note that some assets containing heating elements, filament lamps or very large motors may exhibit a very low resistance in their de-energised state, causing PAT4 to warn of a possible short circuit. In such cases, the warning can be ignored. Note:- If an operation test

44、 is carried out on a short circuit asset, PAT4 may be damaged. If in doubt DO NOT PROCEED. Press the FAIL key, suitably label, and remove the asset from service; investigate and rectify the fault, and re-test on completion. The asset is energised from a low potential / low energy a.c. supply. The op

45、en circuit voltage is typically 12 Volts (peak) with a short circuit current of 100 mA. Insulation Test A 500 Volt D.C. source is used to provide the Insulation test function. Class 1 appliances, are tested by applying 500V between Earth and the two- phase conductors joined together. Class 2 applian

46、ces should be tested using the Bond test lead as a return connection. The insulation test voltage is applied to the appliance phase conductors as for Class 1, but any current flow will return to Earth via the bond test lead which should be connected to the appliance insulation or to any exposed meta

47、l parts. The insulation test has been designed to supply 500 V at 1 mA. Operation Test For an Operation test ensure that the asset is in a safe condition to run and that no hazards are present. Operation tests allow the power consumed by the equipment to be checked against the manufacturers rating.

48、The measurement is displayed in Volt Amps (VA) often specified on assets as Watts. During the Operation test the appliance is powered directly from the incoming mains supply (230V or 110V). During the test the PAT4 also measures the mains voltage at the time of test. If this is found to vary from th

49、e nominal mains value (230 V or 110V) PAT4 will make a correction and display the consumed power as if the mains voltage had been exactly correct. This enables a more accurate comparison with the manufacturers figure. Pre-testing asset. . . . .
