Setting The Director - Meyra Optimus Service Manual

SETTING THE DIRECTOR

The director, actually a measuring potentiometer, is
connected to the steering through gears. It signals to
the power module in which setting the wheels currently
are so that the motor is addressed accordingly.
The gears synchronise the steering and director. If the
gears have shifted to each other by one or more teeth
the wheelchair will drive a curve while the joystick is
set to a straight course. The director then has to be
realigned.
– Set the joystick minimally to backward motion so
that the steering gear engages but the wheels do
not start to turn.
– Pull off the gear (fig. 4–11/ K) that is attached to
the director counter clockwise to the spring pres-
sure of the gear at the steering gear (fig. 4–10), turn
it by one tooth and replace it.
– Check the effect to the steering behaviour and repo-
sition the gear accordingly until on backward,
straight joystick setting no steering reaction is no-
ticeable.
