5. Turn (tighten) the “T” handle
90° to secure handle in the
engaged (locked) position.
6. Verify mechanism is reen-
gaged (locked). View cus-
tomer installed sensor LED,
or pull on the Hand Hold to
ensure no movement occurs.
7. Stow the remaining portion
of the platform by using the
electrical system.
To Manually Raise or Lower
Ramp:
1. Raise and hold platform as-
sembly up to gain access to
the self-locking release pin.
2. Carefully remove release pin,
using caution as the platform
assembly may now move
freely (unhindered).
3. Manually raise or lower the
platform assembly as desired.
Note: The release pin will
only be able to be reinstalled
when the platform assembly
is returned to the original
position in which the pin was
removed.
Electrical Method
Control Box Manual Input
(Override) Switches: Manual
input switches are located inside
the electronic control box. Do
not use manual input switches
to operate the ramp when load-
ing or unloading a passenger.
These momentary contact switch-
es are provided as an override
for maintenance and service
purposes only. Manual input
switches should be activated by
qualified technicians only.
A service technician can use the
manual input (override) switches
to move the carriage assembly
with problems due to debris build
up, wear or mechanical bind-
ing (obstruction sensing will not
allow normal ramp operation).
The switches can also be used
in event of an electrical problem
remote from the ramp electrical
system (such as a problem with a
vehicle installed control switch or
interlock circuit).
Note: There must be power to
the ramp system (electronic con-
troller) in order to use the manual
input (override) switches.
Each respective override switch
can be used to move the ramp
platform in the stated direction
(as labeled); OUT (extend), IN
(retract), UP (raise or elevate) or
DOWN (lower). The IN and OUT
switches use the control logic to
limit the travel to the maximums
as set by the respective sensor
pickups. Caution! The UP and
DOWN switches are not limited
to the sensor pickups, and thus
manual over travel can occur.
Over travel may result in damage
to ramp components or serious
bodily injury if not used with
extreme caution.
Note: A ramp operating un-
der normal conditions via an
operator’s input switch will halt in
the event a manual input over-
ride switch is pressed. Once
released, the controller will
automatically reset and function
normally when the next operator’s
input switch signal is received.
