Adjustment of the scaled value

  1. Relieve the tension on the tower.
  2. Deflect the tower in manual mode in the positive direction by 1/1000 of the tower height (e.g. 20 mm given a tower height of 20 m).
  3. Read the scaled value.
    • In the case of a positive deflection, it must be a negative value that is 10 times the deflection (e.g. -200 at a deflection of 20 mm).
  4. Use the rule of three to determine the numerator and the denominator.

 

Example:

Deflection: 20 mm

Read scaled value: -300

Desired scaled value: -200

 

Consequently: -200 = k*-300

Factor k: k = -200/-300 =2/3

Scaled numerator: 2

Scaled denominator: 3

 

  1. Check the opposite direction.
    • In the case of a deflection of 1/200 of the tower height (e.g. 100 mm given a tower height of 20 000 mm) in the negative direction, the value "+1000" must be displayed for parameter 8582.80 "Total for analog inputs AI 2 + AI 3".
    • INFORMATION: There is a button available for resetting the scaling factors if necessary.
    • INFORMATION: The actual value can be inverted with the help of a negative numerator if necessary.
