Error Code 1200 alludes to an Overspeed Alarm. While the cause of this alarm can vary from one scenario to the next, this could potentially be caused by a faulty 7.5 amp fuse, bad air filter, or insufficient fuel pressure. If issues persist after checking the generator’s 7.5 amp fuse, air filter, and fuel pressure provided (which can be verified by your local fuel line provider), we would then recommend contacting an independent authorized service provider in your local area for diagnostic work.

As natural gas flow is not controlled by utility power, it should still in fact be present, in the event of a utility outage. To confirm that this would be the case with your existing configuration, we would recommend contacting your local natural gas supplier.

Generac’s 20kw generator, model number 6730, is an automatic standby unit which is manufactured to run off of a natural gas or liquid propane fuel source; gasoline is not an applicable fueling option. Considering this, we are unable to provide any recommendations pertaining to operating it in a manual manner. If you are utilizing an alternative transfer switch, we would recommend working with a local independent authorized dealer in your local area, to ensure that your unit and associated switch are installed appropriately in accordance with your local codes.

Question

Question on availability of contact closure reporting an error condition

On a Generac 5505 is there a (normally open) contact closure connection that can be attached to a home alarm system that will accept such a connection that will close on a generator error condition (i.e., operates in parallel with the "red" LED reporting condition).

if so, is it on the main controller board and at which pin positions.

Question

Heat pump compatibility

Can a 20 KW generator be utilized to power a heat pump system at all? Mostly heat pump system I have come across has 60 amp air handler with 30amp auxiliary backup heating strips. This combined load puts a 20KW over full capacity. This is the most popular size residential generator and bang for the buck when fossil fuels are being used to supply the customers primary heating systems. In the north east now fully electric heat pump systems have become much more efficient and popular as well as geo thermal systems to. Both run very effieciently but in very cold weather situations have auxiliary backup electric heaters that kick on and from what I understand within the heat pump systems these heaters are needed for it to operate properly during the defrost cycle so that excludes a relay to lock them out during generator operation. Any thing bigger then a 20kw starts look a little more commercial as well as the price jump is pretty extensive as well. Could you shed some light on this situation please?

Thank you

#2 question - Why did generac stop using the 120volt contactors to feed priority circuits with the Smart switches and convert to 24vac coil voltages? and why have these signals from the smart switch normally closed contacts. It seems a normally open control signal would exclude the DLM contactor coil from being actuated 24/7. This could be done in the controllers altering the program a bit with and few simple gateways. I am curious why they route it this way.

While particular electronics or appliances may be able to be connected to your automatic standby generator and associated transfer switch, we would recommend working with an independent authorized dealer in your local area, to ensure the safe operation of your intended back-up loads. To locate an independent authorized dealer closest to you, please use your postal code for searching purposes via the following link: http://www.generac.com/dealer-locat.... Also, Generac’s Guardian Series 22kw automatic standby generator, model number 6553, is an air-cooled generator; liquid-cooled units will feature alternative enclosures that will require different configurations. Moreover, due to product modifications to particular models of our transfer switches, we have upgraded to a 24v module for load management. While the DLM modules were 120v, as you have alluded, the newer units utilize a PMM that is a 24v part.

The (H) reading on your unit’s control panel would allude to the amount of time that has passed since your unit was setup for automatic operation. Considering this, if your unit currently reads “2(H)”, this would insinuate that 2 hours have passed since your unit was installed and activated.

Our air-cooled units need to have 18 inches of clearance from the back, 3 ft on either side and in front, 5 ft above, and 5ft from any window, door or vent leading into the home. Moreover, we would recommend ensuring that you will not be restricting the flow of air to the unit, as it is an air cooled generator that requires proper ventilation; any damage due to lack of air provided to the unit is not covered under the product's warranty. Please note, however, that these recommendations are always superseded by local codes.

If the T1 fuse in the transfer switch is blown, the T1 line provided at the generators control panel is not appropriately connected, or if the battery on the unit is low or dead, the “CHARGER MISSING AC” alarm will appear on the unit’s control panel. Considering that you have not hooked up the wiring to your unit at this time, this would likely be the cause of the current reading on your unit’s control panel. If issues persist after all of the wiring has been appropriately applied, we would recommend contacting an independent authorized service provider for diagnostic work. Please note that we would recommend removing the unit’s battery until wiring can be installed, as leaving it connected will cause the battery to drain and render the battery inoperable if/when it is prepared for use.

Generac designs our standby generators with sound attenuated panels and an aluminum, steel, or composite enclosure to minimize noise whenever possible. We make our best effort to manufacture our home standby generators to meet the noise level expectations of our customers. However, there are certain elements of operation that must be considered with an air-cooled engine driven product such as air flow requirements that limit our ability to further sound-proof the enclosure.

Also, please note that Generac’s 20kW automatic standby generator, model number 6730, features a noise rating of 66dB, at a distance of 23 feet, while operating at normal load. Also, when exercising the unit in Quiet-Test mode, the unit will exercise at 60dB, at a distance of 23 feet. Please know that we do not offer other accessories to allow for quieter operation, however, structural or decorative elements, such as a privacy fence, installed at an appropriate distance away from the unit may assist in reducing the noise experienced at a property line. The Guardian Series air cooled automatic standby generators require a minimum clearance of 36” from the ends (short sides) of the generator. However, the distance required from the unit to any window, vent, door, opening into the home, and trees, plants or shrubs over 12” in height is a minimum of 60”. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

The “INSPECT BATTERY” alarm, and associated yellow LED light, allude to a maintenance reminder that will occur on an annual basis. To properly inspect the battery, we would recommend following the recommendations listed in your unit’s owner’s manual. To remove the side panel, merely unlock the unit’s hood, lift it up, and pull the front panel straight up. Once the panel is removed, the battery compartment should be revealed in the lower right hand corner of the unit’s enclosure. If your battery is not appropriately charged, we would recommend verifying that the T1 fuse, along with the T1 connections are appropriately applied in the generator and associated transfer switch. If the battery is dead, it would need to be replaced. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

I am under the impression that you want to see what the generator is capable of handling during a power outage? Other than what you were told.

Whole House Circuit Only

You may want to hire an electrician that has a amp clamp. turn on al your essential circuits and measure for 15 -20 min record in rush amps as well. As you add each additional light monitor amps. a safe load percentage According to NEC for your 20 kw is about 75% load capacity. 65 amps is a safe number. The rest can be used for surge and in rush amps.

Now if you want to know what is hooked up to your emergency panel . Simply turn all lights on and take notes what you have turned on .Kill service entrance breaker and review notes . Whatever is on after generator has took over is Emergency whatever stays off is non emergency . Wall plugs usually are on same breaker that your lights for each room are on .

When installed appropriately, with the necessary configuration for supplying liquid propane fuel, the slight smell of propane is not uncommon. However, if you are concerned about the strength of the scent, we would recommend referring to your fuel line installer, to ensure that all connections were made appropriately, as a potential leak in the fuel line, or improper installation, could potentially be the cause of a stronger propane smell. Please note that the our automatic standby generators are manufactured for use with a natural gas fuel source out of the factory; the unit would need to be reconfigured for use with a liquid propane fuel source, per the recommendations listed in your unit’s owner’s manual.
