• LED 2 is YELLOW. This LED is on when the circuit

 

board battery charger is on. This LED will cycle on

 

and off with the battery charger, 4.85 hours on the

 

4.85 hours off.

• LED 3 is GREEN. This LED will flash when the cir- cuit board has load voltage available to it. This LED will function when voltage is available across T1 and T2.

‹ 1.7.6 OVERCRANK SHUTDOWN

After 90 seconds of crank-rest cycles, this function ends cranking if the engine fails to start in that 90-second span.

‹1.7.4 OVERSPEED SHUTDOWN

The Pre-pack circuit board on liquid cooled units receives AC frequency (rpm) signals directly from the stator AC power windings, via sensing leads S15 and S16. Should AC frequency exceed about 72 Hz, cir- cuit board action will automatically shutdown the engine (Figure 1.7).

*Rated power of generator is subject to and limit- ed by such factors as ambient temperature, alti- tude, engine condition, and other factors. Engine power will decrease about 3.5% for each 1000 feet above sea level and will decrease an additional 1% for each 10°F above 60°F. Maximum output power of the generator is limited by maximum engine power.

‹1.7.6 DC FUSE

This clearly labeled fuse is located on the front panel of the control system. It protects the panel wiring and components from damaging overload. Always remove this fuse before commencing work on the generator. The unit will not start or crank if the fuse is blown. Replace the fuse with one of the same size, type, and rating. Generac normally uses an AGC fuse rated at 15 amps (part number 022676).

‹1.8.1 UNPACKING PRECAUTIONS

Handle shipping cartons and crates with care. Use care to avoid damage from dropping, bumping, colli- sion, etc. Store and unpack cartons with the proper side up, as noted on the shipping carton.

Generac is renowned for its innovation in the power generation industry, and their range of generators—including models 0047210, 0047220, 0047230, 0047240, 0047250, 0047251, 0047252, 0047253, and 0047260—showcase advanced technologies and functionality that meet diverse power needs.

One of the standout features of these models is the use of Generac’s G-Force Engine, specifically designed for reliability and longevity. This engine is notorious for its durability, capable of handling demanding workloads and proving to be more efficient than typical engines found in similar generators. It provides quick start times, lower emissions, and is built to withstand extended operational cycles.

Another notable technology in these models is the Quiet-Test™ mode, which enables the generator to run at a lower RPM while it performs an exercise routine. This feature not only reduces noise during operation but also conserves fuel, making it an eco-friendly option that doesn’t compromise on performance.

The generators are equipped with advanced monitoring and control features, including the Mobile Link™ application compatibility. This allows users to monitor the status of their generator remotely via a smartphone or tablet, offering peace of mind and real-time access to the generator's operational functioning. This connectivity also enables the user to receive alerts and notifications about maintenance needs or when the generator is in need of attention.

In terms of design, these models boast a robust steel enclosure that offers superior protection against the elements, thereby enhancing durability and ensuring efficient operation regardless of weather conditions. The enclosures also come with a weather-resistant finish, making them suitable for outdoor installation.

Moreover, the generators feature a well-thought-out installation process with easily accessible controls and noise-reduction technology, which helps minimize disturbances for residential applications. They also offer multiple power outputs, catering to varied energy needs, from essential home appliances to larger devices.

Safety is a core consideration with Generac models, and features such as the automatic shutdown mechanism prevent overheating, ensuring operational safety during use. Coupled with an efficient fuel consumption rate, these generators stand out as impeccable solutions for power backup in homes and businesses alike.

The series exemplifies Generac’s commitment to excellence in power solutions, integrating user-friendly technology, efficient performance, and top-tier safety into compact, durable designs. Users can rely on models 0047210 to 0047260 for dependable power generation tailored to their specific needs.
