Other Items Not Furnished by Eaton There are several items uniquely required in the Digital II System that are not furnished by Eaton. In addition to the meter pulser, the accumulator system used on servicers is furnished by the customer. This system consists of an accumulator with a usable volume of at least one gallon (4 liters), a ¼-inch check valve and a dry break disconnect as shown in the hydrant servicer system figure on page 6. This system is used to provide stored power to get the coupler to open upon activating the deadman at the beginning of each refueling. It must be initially charged to a minimum of 60 psi (4.137 bar) after the building of the vehicle and after the system has been removed for service and depressurized for any reason. Once the initial charging has been achieved, the hydrant system will keep the accumulator system charged. A larger accumulator may be required should the hydrant system pressure be less than 90 psi (6.205 bar) at any time during a refueling. Ordering Data
