11:Hed in lby W AJoi,ies <br />System will include a diagnostic board with direct reading LED <br />circuit indication. <br />Wiring system will exclude any infusion of direct application of <br />1000 PSI pressure wash spray. <br />Connectors shall withstand 500 hours of 35C salt spray. <br />The controller will also offer a combination "blast" - <br />"unload" switch. This switch will allow the controller to <br />produce a Blast function with programmable duration and a <br />maintained unloads position for unloading the spreader or <br />offering continuous, operation during cleaning. The <br />controller will allow the attachment of speed pickup to start <br />and stop the material spreading with vehicle motion. <br />Wiring harness for the spreader control shall be full factory <br />assembled with waterproof ends and covered in expanded <br />nylon abrasion sleeve. A separate fuse shall be included <br />into the controller to protect it in the event of a short circuit <br />deploying the inline fuse included in the installation. <br />Controller shall be mounted in the cab with all hydraulic <br />lines and valves outside of the operator's compartment. <br />All wiring that leaves the cab, such as valve supply and <br />speed pickup, shall be secured with rubber covered steel <br />clamps and include a watertight strain relief at the: cab exit. <br />Control Valve: The control valve shall be US manufactured. The valve is to be UE� NO <br />Greisen Model V40/V20 or equal load sensing stackable spool <br />type with 0-ring ports mounted between the frame rails outside <br />the vehicle cab. Hoist section and tool circuitry section to be <br />V40 and all other sections to be V20. Valve sections to be <br />arranged as follows: <br />Hydraulic Valve: The hydraulic valve will be a cast iron, sectional type <br />spool valve. Valve will feature individual section and flow compensation for <br />each section. The valve will be rated for a nominal flow of 30 gpni. The load <br />sensing shuttle network will be accessible without valve disassembly, <br />Sections will be provided for following: <br />1. Hoist, double acting cylinder with down side work, port relief <br />set as 500 psi, <br />2. Mid-inlet/transition section. <br />21 <br />
