DESCRIPTION & COMPONENTS

or DPE winding, (c) a center tapped battery charge winding and (d) a 10 Amp center tapped battery charge winding. Insulation tests of the stator con- sist of (a) testing all windings to ground, (b) testing between isolated windings, and (c) testing between parallel windings. Figure 3-9 is a pictorial representa- tion of the various stator leads on units with air-cooled engine.

TESTING ALL STATOR WINDINGS TO GROUND:

1.Disconnect stator output leads Wire 11 and Wire 44 from the generator 50A circuit breaker.

2.Remove stator output lead Wire 22 from the neutral terminal on the back of the 50A outlet.

3.Disconnect the C1 connector from the bottom of the control panel. See Figure 3-10. The C1 connector is on the right when facing the control panel.

4.Connect the terminal ends of Wires 11, 22, and 44 together. Make sure the wire ends are not touching any part of the gen- erator frame or any terminal.

5.Connect the red test probe of the Hi-Pot tester to the joined terminal ends of stator leads 11, 22, and 44. Connect the black tester lead to a clean frame ground on the stator can. With tes- ter leads connected in this manner, proceed as follows:

a.Turn the Hi-Pot tester switch OFF.

b.Plug the tester cord into a 120 volt AC wall sock- et and set its voltage selector switch to “1500 volts”.

c.Turn the tester switch ON and observe the breakdown lamp on tester. DO NOT APPLY VOLTAGE LONGER THAN 1 SECOND. After one (1) second, turn the tester switch OFF.

If the breakdown lamp comes on during the one-sec- ond test, the stator should be cleaned and dried. After cleaning and drying, repeat the insulation test. If, after

cleaning and drying, the stator fails the second test, the stator assembly should be replaced.

6.Now proceed to the C1 connector ( Female side – Just removed). Each winding will be individually tested for a short to ground. Insert a large paper clip (or similar item) into the C1 connector at the following pin locations:

TEST BETWEEN WINDINGS:

1.Insert a paper clip into Pin Location 3 (Wire 55A). Connect the red tester probe to the paper clip. Connect the black tes- ter probe to Stator Lead 11. Refer to Steps 5a through 5c of

“TESTING ALL STATOR WINDINGS TO GROUND”.

2.Repeat Step 1 at Pin Location 6 (Wire 2) and Stator Lead 11.

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.
