Manual Operating Instructions
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
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.
