SERIES SERVICE MANUAL
I. FOLDOVER® ELECTRIC FR2E-SERIES RAMP INTRODUCTION
his manual applies to the Ricon FoldOver® Electric FR2E-Series Low-Floor Vehicle Access Ramp when installed
in transit vehicles. The chapters in this service manual contain product description, maintenance instructions, and
a spare parts list. The descriptions in this chapter apply to the Ricon FoldOver® Electric FR2E-Series Low-Floor
Vehicle Access Ramp when installed in transit vehicles utilizing 12VDC or 24VDC applications. The FoldOver
electric ramp is installed in low-floor transit vehicles to accommodate persons with disabilities using mobility-aid equip-
ment or who cannot easily climb steps. The electro-mechanically powered ramp folds into the vehicle vestibule flooring
when not in use.
All Electric FR2E-Series ramps have a 1,000 lbs. (453 kg) load limit. Passengers must use the ramp one at a time; do
not overload ramp. Be certain that persons with mobility-aid equipment fit between the left- and right-side ramp barri-
ers without any interference before allowing use of ramp.
FIGURE 1-1: RICON FOLDOVER FR2E ELECTRIC LONG AND SHORT RAMP
A. RAMP FEATURES
1. INTERLOCK SUPPORT
The ramp electronics can interface with the vehicle interlock circuitry to prevent vehicle departure when ramp
is deployed. The electric ramp interlock circuitry senses the position of the ramp (stowed or deployed) and
makes this information available by the controller and through the 55-pin amp harness connector. A vehicle
interlock circuit typically requires that the following conditions be met before operating power is supplied to
electric ramp:
 Park vehicle and set parking brake.
 Place transmission in neutral.
 Open vehicle door adjacent to electric ramp.
2. AUDIBLE ALERT
NOTE: This feature is optional and may not have been connected during ramp
installation.
The ramp supports an audible alert device that sounds while the ramp
is in motion.
3. RAMP CONTROL PANEL
Refer to Figure 1-2. Ricon typically does not provide a control panel.
However, the ramp can be operated with one similar to that shown (the
actual panel appearance will vary between transit authorities and vehi-
cles). The control panel is normally installed in the driver area. It should
have a power ON/OFF switch, a power on indicator light, and a spring-
loaded, three-position ramp control switch (center-off). The electric ramp
receives power from the vehicle when the interlock conditions are met and
the power on/off switch is ON. The control panel can then be used to
transmit deploy or stow signals to the electric ramp.

II. FOLDOVER® ELECTRIC FR2E-SERIES RAMP INSTALLATION
A. INSTALLATION GUIDELINES
Careful installation of the Ricon FoldOver® Electric FR2E-Series Low-Floor Vehicle Access Ramp contributes to
proper and safe operation. Use the electrical wiring diagram in Chapter III, Figure 3-4 to supplement this sec-
tion.
1. LOCATING MOUNTING BRACKETS ON BUS FRAME
Use a rigid fixture that substitutes for the ramp assembly when positioning ramp mounting brackets on the
bus frame. If the ramp assembly is used to position the mounting brackets, verify that it is correctly located
relative to the vehicle floor, etc. Accurate positioning of the brackets prevents twisting or warping of ramp
frame when installing and tightening the mounting hardware. A warped frame may cause the ramp motion
to be erratic. Set the height of the ramp flooring surface flush to the surrounding floor structure to prevent a
tripping hazard.
2. INSTALLING ELECTRIC FR2E-SERIES LOW-FLOOR VEHICLE ACCESS RAMP IN FLOOR
The location of the ramp depends on its path of motion. The ramp must be positioned so it can move un-
obstructed through its required range of travel.
a. Trim away floor material to allow ramp assembly to drop into floor opening.
NOTE: Do Not install ramp trim (flange kit) until ramp is installed in bus. The ramp trim overlaps the perimeter
gap between the sides of the enclosure and bus structure. The typical gap between the sides of the
enclosure and the bus structure is 1/8 inch. Use shims to fill gap.

END OF TABLE
D. RAMP COMPONENT INFORMATION
Ricon FoldOver® Electric FR2E-Series Low-Floor Vehicle Access 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. ELECTRIC 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 converts electrical power into mechanical force through the crank shafts when either the
DEPLOY or STOW micro-switches are activated and controlled by an electronic controller. Ricon recommends op-
erating the ramp while the vehicle engine is running in order to minimize current drain on the vehicle battery.
2. TRAY POSITION SWITCH ASSEMBLY
A factory adjusted tray position switch assembly identifies the DEPLOY or STOW position of the ramp tray as the
electro-mechanical drive system transfers motion from the crank shaft, through the chain, onto the CAM shaft. The
CAMs attached on the rotating CAM shaft activate the micro-switches which relay signals to the electronic controller
that controls the functions of the ramp.
3. ELECTRONIC CONTROLLER
The electronic controller interprets input/output signals from the micro-switches and controls ramp functions by re-
laying signals to/from the control box. It contains integrated circuits (ICs), relays, fuses, and associated parts. The
ICs cannot be accessed externally. The 55-pin ramp connector receives 12V/24V to power the controller and sends
12V/24V through the control box that controls power to the motor drive system.
Refer to Figure 3-1 for connector and controller connection. Controller only requires one 55-pin connector connec-
tion.

NOTE: Voltage levels are 24 to 28 VDC in this application.
4. INTERLOCK OUTPUT STATUS
The FoldOver Electric ramps has two ramp positions that are monitored by the controller. This position is fully
stowed to deployed position. The ramp must be in the fully stowed area before the electrical interlock output signal
will turn on (24VDC). This is done to reduce the possibility of a passenger tripping on the front edge of the ramp
when it is not stowed completely as well as preventing the bus from operating or moving when ramp is deployed.
Refer to Table 3-3. The status of the interlock output (GND or 12VDC/24VDC) occur when the ramp is either
STOWED or DEPLOYED. Note that the interlock output has both a normal and an inverted output. This table ap-
plies to the normal output.

5. CIRCUIT BREAKERS AND FUSES
The bus builder installs a 50-amp circuit breaker for 12V or 24V applications to protect ramp control circuits. Refer
to Table 3-4 for harness fuses.
