DIAGNOSTIC TESTS

2.If load is within limits, but frequency and voltage still drop excessively, refer back to Flow Chart.

TEST 17 - CHECK BATTERY CHARGE

OUTPUT

PROCEDURE:

1.Disconnect Wire 15 (center terminal) from the Battery Charge Rectifier 2 (BCR2), which is located under BCR1. They are stacked. See Page 17 for BCR2 location.

2.Set a voltmeter to measure DC Amps. Connect the positive (+) test lead to the center terminal of the Battery Charge Rectifier. Connect the negative (-) test lead to Wire 15 previously discon- nected.

3.Start the generator. The amp reading on the voltmeter should be approximately 0.6 Amps. Apply full load to the generator. The amp reading should increase to approximately 2 Amps.

RESULTS:

1.If amperage was measured between 0.6 to 2 Amps in Step 2 and Step 3, the charging system is working.

2.If no amperage was measured, check the voltmeter fuses and verify the functioning of the Amp Meter. If DC Amp Meter is good and no current is measured refer to flow chart.

TEST 18 - CHECK 10 Amp BATTERY CHARGE

OUTPUT

PROCEDURE:

NOTE: The battery charge cable must be connect- ed to the 12 VDC panel receptacle and be charging a separate battery to perform this test.

1.Disconnect Wire 13A (center terminal) from the Battery Charge Rectifier 1 (BCR1), which is located on top of BCR2 they are stacked. See Page 17 for BCR1 location.

2.Set a voltmeter to measure DC Amperage. Connect the posi- tive (+) test lead to the center terminal of the Battery Charge Rectifier. Connect the negative (-) test lead to Wire 13A previ- ously disconnected. See Figure 6-24.

3.Start the generator. The amp reading on the voltmeter should be approximately 0.2 Amps. Apply full load to the generator. The amp reading should increase. It will depend upon the state of charge of the battery as to how high current will get. Normal ranges at full load can be 3-7 amps, but can get as high as 10 amps.

RESULTS:

1.If amperage was measured between 0.2 to 10 Amps in Step 2 and Step 3, the charging system is working.

2.If no amperage was measured, check the voltmeter fuses and verify the functioning of the Amp Meter. If DC Amp Meter is good and no current is measured refer to flow chart.

Test 19 - Check Battery Charge

Rectifier (BCR2)

PROCEDURE:

1.Disconnect all wires from the Battery Charge Rectifier.

2.Set the VOM to the Diode Test range. Connect the negative (-) test lead to the center terminal of the BCR. Connect the posi- tive (+) test lead to an outer terminal. The meter should mea- sure approximately 0.5 volts. Now connect the positive test lead to the other outer terminal. Again, the meter should measure approximately 0.5 volts.

3.Connect the positive (+) test lead to the center terminal of the BCR. Connect the negative (-) test lead to an outer terminal. The meter should measure INFINITY. Connect the negative test lead to the other outer terminal. INFINITY should once again be measured.

5308, 4583, 4451 & 4986, 4582 & 4987 specifications

Guardian Technologies has carved a niche in the market with its innovative air purification and UV-C sanitization products. The company's model numbers, including 4582, 4987, 4451, 4986, 4583, and 5308, represent a diverse range of solutions designed to enhance indoor air quality and safety in both residential and commercial settings.

The Guardian Technologies 4582 is equipped with a true HEPA filter that captures 99.97% of dust, pollen, smoke, and other particles as small as 0.3 microns. This model features a smart sensor that adjusts the fan speed according to the air quality in real-time. The UV-C light technology integrated into this device works to eliminate viruses and bacteria, providing an additional layer of protection against airborne pathogens.

The 4987 model follows suit with similar advanced features but adds a sleek design ideal for modern interiors. With multiple speed settings and a night mode, the 4987 is perfect for bedrooms or quiet spaces. Its energy-efficient operation coupled with an indicator that signals filter replacement ensures that users maintain optimal performance effortlessly.

The Guardian Technologies 4451 and 4986 models are particularly notable for their enhanced capacity and filtration efficiency. Both units incorporate a three-in-one filtration system that includes a pre-filter, activated charcoal filter, and HEPA filter. With their strategic design, these models not only purify the air but also trap common household odors, making them a popular choice for families with pets.

The 4583 model stands out with a unique combination of design and functionality. It features a low-profile design, making it easy to fit into any space. Its UV-C light technology not only disinfects air but can also sanitize surfaces, bridging the gap between air purification and direct sanitation.

Finally, the Guardian Technologies 5308 caters to larger spaces, offering impressive air circulation and filtration capabilities. Equipped with a high-efficiency particulate air (HEPA) filter and a powerful fan, it effectively cleans larger areas while maintaining whisper-quiet operation.

In summary, Guardian Technologies’ products exemplify a commitment to improving air quality and promoting health through innovative technology. With features like HEPA filtration, UV-C sanitization, smart sensors, and sleek designs, consumers can choose from a range of models that best fit their needs, ensuring cleaner, safer indoor environments.
