RAMP TERMINOLOGY
Ramp Components
Refer to the Terminology Illustra-
tions on pages 2 and 3.
Control Box (Electronic Con-
troller): The remote mounted
control box provides the logic to
manage the inputs in order to
produce the desired outputs in
terms of ramp function and per-
formance. In general terms the
control box is commonly referred
to as the “controller”.
Pan Weldment (Housing):
The pan is the aluminum (casing)
mounted in the vehicle floor sys-
tem which contains the electrical
components that power the ramp
electrical systems. The fixed
sub-floor cover protects the com-
ponents from above. The cover
is easily removed for access to
drive components. The sub-floor
provides an antiskid surface for
entry and exit when the ramp
is deployed. The RA500 ramp
stows into the sub floor
providing an unobstructed an-
tiskid surface for entry and exit
when the ramp is not in use.
Ramp Platform: The ramp
platform is the aluminum ramp
section assembly featuring a full
antiskid surface.
Chain Drive Assembly: The
electric motor driven chain drive
deploys and stows the ramp plat-
form assembly.
Ramp Actions and Functions
Extend: Extend is the action of
the platform moving out of the
pan weldment (housing).
Retract: Retract is the action of
the platform moving in to the pan
weldment (housing).
Deploy: Deploy is the action of
the ramp assembly extending to
ground level when the DEPLOY
(OUT) switch is activated.
Stow: Stow is the action of the
ramp assembly retracting inward
to the stowed position when the
STOW (IN) switch is activated.
Note: the one touch control-
ler activates both the stow and
deploy functions, dependant upon
the state of the RA500.
Stowed Position: Stowed
position is achieved when the
ramp platform assembly is fully
retracted (resting fully in the pan
weldment).
Manual Override: Manual
operation is achieved through
the use of a mechanical release.
Simply pull the release and use
the hand hold provided on the
ramp platform to manually deploy
or stow the ramp. Minimal physi-
cal effort is required to stow and
deploy the ramp platform. Slow
steady motion results in the least
resistance and easy operation.
See pages 2 and 3 for detailed
manual release procedure.
Obstruction Sensing: An ob-
struction sensing feature is stan-
dard with the RA500 ramp. The
controller monitors the instanta-
neous movement of the electric
motor, and calculates a “real time”
running average of the current. It
then compares the programmed
peak (maximum vs. instanta-
neous) and delta (instantaneous
minus running average) limits to
determine if an obstruction has
been encountered.
Weight Sensing Pad (optional):
The platform can be equipped
with a weight sensing pad. This
optional feature will cause the
ramp not to operate in the event
that 5 kilograms or more is on
the ramp platform.
