4. D OF TABLE D RAMP COMPONENT INFORMATION Ricon FoldOver 1 6 Ramp uses electrical power from the host vehicle to deploy and stow the ramp Vehicle electrical power is converted to mechanical force which is used to move the ramp Electrical components are described below Please refer to Figures 3 4 for electrical diagram 1 MOTOR DRIVE SYSTEM The ramp employs an electro mechanical motor drive system contained within the ramp enclosure Settings are programmed in the motor drive system and is preset at Ricon The motor drive system provides mechanical force to the chain spring actuator assembly when either the DEPLOY or STOW switch is activated Ricon recommends operating the ramp while the vehicle engine is running in order to minimize current drain on the vehicle battery 2 CHAIN SPRING ACTUATOR ASSEMBLY Two factory adjusted chain spring actuator assemblies control the Stow and Deploy motion of the FoldOver 1 6 ramp Their adjustment determines the degree to which the ramp will rotate opened or closed 3 ELECTRONIC CONTROLLER The electronic controller interprets DEPLOY and STOW requests and controls ramp functions It contains inte grated circuits ICs relays fuses and associated parts The ICs cannot be accessed externally The 55 pin ramp connector receives 24V to power the controller and sends 24V to power the motor drive system Refer to Figure 3 1 for connector and controller connection Controller only requires one 55 pin
