PRECAUTIONS - ROTATING AUTOTUNE
1. These instructions should be read in their
entirety before proceeding.
2. It is the responsibility of the competent
person to take all precautions as required when
conducting the following.
3. It is important that the lift car is prevented
from moving whilst an auto tune is being
conducted and that the motor shaft can revolve
freely. This normally implies that the motor be
disconnected from the gearbox where fitted or
that the lift is adequately secured in the well so
as to prevent movement and the ropes lifted
from the drive sheave, and additionally that the
brake is lifted.
4. Ensure that if the motor is disconnected from
the gearbox, then the motor shaft key is
secured or removed, as the motor rotates
during autotuning.
5. Ensure that no fault condition is present.
