Application Note 1

The auto regulated HACA load bank design provides a permanent solution to prevent generator diesel engine failure due to wet stacking.
Wet stacking occurs due to under loading of the genset which results in wet un-burned fuel building up in the engine.
This fuel build up will over time line the combustion chamber cylinders and cause a reduction of the engines rating and efficiency which will ultimately cause premature failure of the generator. Running the generator on load of 50% - 100% of the genset rating will allow the engine to reach the recommend operating temperature, which will burn off the choke deposits.

Application Note 2

Battery Discharge testing is the approved method to determine the capacity of Lead acid and (Nickel Cadmium) Ni Cad/Ni Cd batteries, as recommended by all battery manufacturers such as Enersys, Exide, C&D Technologies, Hawker, Yuasa, Exide, Hoppecke, Saft, Varta, and in accordance to BS6290 part 4 / IEC TR 62060.
