Fitting the Combined End Stops/Charging Ramps
The combined end stops/charging ramp units are used, as the name
suggests, to stop the carriage at the end of the rails and to recharge the
batteries while the lift is not being used. They should be fitted at both the
bottom and the top of the rail. The carriage batteries are charged when the
brass plunger on the back of the bottom skate of the carriage comes into
contact with the charge ramp.
The units can be used to set how high or low the start and finish point of the
carriage will be on the completed stairlift.
Each unit consists of three methods of stopping the carriage. The usual
method of stopping the carriage being the spring loaded plunger mounted
on the end stop. This plunger connects with the sprung metal end stop
plate on the bottom skate of the carriage. If this method fails for any reason,
the shape of the charge ramp is such that if the carriage travels past it’s
usual stopping point, the brass plunger on the carriage will be depressed
too far
and “over-run”. This will break the final limit circuit, bringing the
carriage to a halt. In the unlikely event of both of the above methods failing,
there is a physical buffer that covers the teeth on the racking, forcing the
carriage to stop when the pinion comes into contact with it.

:
The fixing of the end stop and the distance between the stop and the
charge ramp is crucial to the safe and reliable operation of the stairlift.
To fit the combined end stops/charging unit, place the carriage in the
correct position to allow the customer to easy access. Place the end stop
unit on the bottom rail with the spring loaded plunger touching the metal
end stop plate on the carriage and, holding the end stop unit in position
move the carriage away along the track.
Drill and tap two holes in the lower
rail using a 4.2mm drill bit and
5mm tap. Attach end stop with the
M5 x 10 button head cap screws
supplied.
When the carriage comes to rest
against the end stop, the charge
plunger on the carriage should
make a good contact with the
charge ramp on the endstop unit.
The plunger should travel between a third and half way up the first face of
the charge ramp. Too little and a good electrical contact will not be made
and the batteries will not charge reliably. Too far and the final limit circuit
will be broken and the lift will not move.
This contact position can be set by moving the postion of the charge ramp
along its mounting on the end stop assembly.
When adjusting, ensure the
charge current is not connected.
