5.10 Adjusting the spring force
The spring is not tensioned when delivered. A primary
tension of at least 10 rotations is required for the operation.
The adjustment will be tested during the teach-in run. The
teach-in run will be aborted if the spring force is too low. A
new teach-in run must be carried out if the spring has been
readjusted.

Refer to the table to find the required rotations for the
spring adjustment and adjust the spring force.
