DIAGNOSTIC TESTS

Short to Ground:

4.Set the VOM to measure resistance. Connect the positive (+) test lead to the case housing of the BCR. Connect the negative (-) test lead to an outer terminal. INFINITY should be mea- sured. Now connect the negative test lead to the BCR center terminal. INFINITY should be measured. Next, connect the negative test lead to the remaining outer BCR terminal. Once again INFINITY should be measured.

RESULTS:

1.If any of the previous steps has failed, replace the Battery Charge Rectifier.

2.If the BCR tests good, refer back to the flow chart.

TEST 20 - CHECK 10 AMP CIRCUIT BREAKER

PROCEDURE:

1.Set a voltmeter to measure resistance.

2.Locate the 10 Amp circuit breaker (CB1) in the control panel. See Page 17 for Circuit breaker location.

3.Disconnect Wire 15A and Wire 13A from the circuit breaker.

4.Connect one meter test lead to one terminal of the circuit breaker. Connect the other meter test lead to the remaining terminal on the circuit breaker. Continuity should be measured. See Figure 6-26.

RESULTS:

1.If continuity was measured the breaker is good refer back to the flow chart.

2.If INFINITY or a open condition was measured replace the circuit breaker.

Test 21- Check 10 Amp Fuse

Figure 6-27. – 10 Amp Fuse (Located in Rear of

Control Panel)

PROCEDURE:

Push in on fuse holder cap and turn counterclockwise. Then, remove the cap with fuse. Inspect the Fuse.

RESULTS:

If the Fuse element has melted open, replace the Fuse with an identical size fuse. If Fuse is good, refer back to flow chart.

Test 22- Check Battery & Cables

PROCEDURE:

1.Inspect the battery cables and battery posts or terminals for corrosion or tightness. Measure the voltage at the terminal of the Starter Contactor and verify 11-12 volts DC is available to the generator during cranking. If voltage is below 11 volts DC,

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.
