6.3 Programming
6.3.1 Programming Summary
This procedure describes how to completely program the Stairlift. If the batteries are disconnected at any time
the program will be retained, except for the Datum Position and Top Terminal limit, which then must be
re-programmed in.
The lift orientation is set Left Hand or Right Hand for the program. Factory set.
A datum position is set at the top of the rail as the lift leaves the top charge point.
The top charge point position is set (Terminal Limit).
Carriage speeds are programmed in as the lift moves down the rail.
The bottom charge point position is set (Terminal Limit).
Programming is then completed for both up and down travel.
Three carriage speeds are possible:
CREEP SPEED (slow) is the default setting and is used just before stopping.
BEND SPEED when moving around vertical, inside horizontal bends and helical bends. It is also used as an
intermediate speed.
FULL SPEED along straight rail sections.
