The RA200 has the capability of being manually operated (me- chanical or electrical methods). If you experience power or equip- ment failure, refer to the step- by-step instructions to manually operate the ramp. Always use ex- treme caution when operating the ramp manually. Read all Manual Operating Instructions carefully and thoroughly prior to perform- ing manual operating procedures. Follow all Ramp Operation Safety Precautions at all times.
Mechanical Method
Cable-Activated Manual Re- lease System: A cable activated manual release system disen- gages (unlocks) the carriage as- sembly drive chains to allow the platform assembly to be manually extended or retracted as required. A T-handle is provided on the release cable for activation of the manual release system (details follow).
After manually extending or retracting the platform assembly, it is extremely important that the cable-activated manual release is positively reengaged to secure (lock) the platform assembly before loading a passenger or continuing vehicle use (details provided). Failure to reengage and secure the platform may result in unintended ramp movement, which may result in serious bodily injury and/or property damage.
Manual Release System Secu- rity Sensor: A proximity sensor detects when the cable-activated manual release system is disen- gaged (unlocked) and provides a ground (-) "unlocked" signal to the controller. The unlocked signal disables all controller functions so that the mechanism can be manu- ally operated without the risk of
injury. The unlocked signal may also be used to supply a visual display to the operator that the ramp is unlocked and must be secured prior to any additional operation of the ramp or vehicle. Note: The unlocked sensor LED is not supplied (customer installed).
Self-Locking Release Pin: A self-locking release pin allows the platform assembly to be disconnected from the elevation mechanism, allowing a raised platform to be manually lowered in the event of a power failure. See Photo below. The release pin should only be used when the platform will not lower under electric power, as stated in the Electrical Method section (next).
To Manually Extend or Retract Ramp:
1.Turn (loosen) the manual release “T” handle 90°.
2.Pull the “T” handle fully out- ward (3" to 4").
3.Turn (tighten) the “T” handle 90° to secure handle in the disengaged (unlocked) posi- tion.
Self-Locking Release Pin
4.Verify mechanism is dis- engaged (unlocked). View customer installed sensor LED.
5.Carefully move the platform in or out to desired location using the platform Hand Hold.
Reengage Carriage Assembly by Drive Chains:
1.Position the ramp platform manually so that only 15 cm is extended out of the cas- sette.
2.Turn (loosen) the manual release “T” handle 90°.
3.Push the “T” handle fully inward until handle contacts shaft shoulder (3" to 4").
4.Grasp the platform Hand Hold and move the platform slightly outward until platform locks into position (secured by reengaging the carriage as- sembly with the drive chains). Note: Do not push platform inward to lock as it may then create a binding condition in the release mechanism and will not release easily in the future
WARNING
Push T-handle in fully and manually move platform in and out to engage platform lock before driving vehicle. Failure to lock platform may result in unintended platform deployment. Unintended platform deployment may result in serious bodily injury and/or property damage.
