Changes in the EN-81 calculation
In an elevator group with 2 or more similar shafts, the pit of the second shaft needed to be higher than the pit of the first shaft, according to the calculation. This issue has been fixed.
In Annex M, the direction or sense of the acceleration used for all four cases in the emergency braking situation (both on the car and counterweight sides) was wrong. This issue has been fixed.
The Results for "Normal Operation" and "Emergency braking" situation on the Car/ Counterweight side were not calculated correctly according to the standard Acceleration/ Deceleration value, when opening the Traction Calculation dialog for the first time. This issue has been fixed.
Although, the undercut for the traction sheave v-groove was not defined in the Grooving Consideration settings of the Rope Calculation, it still was taken into account in the calculation reports. This issue has been fixed.
