If the distance A is still smaller than 40 mm after the removal of two distance blocks, the
STMs must be shortened so that:
– the distance A is close to 80 mm but no more
– there are two distance blocks in place.
Prior to shortening the STMs, make sure that they are in good condition, otherwise
replace them instead of shortening.

1
Move the car up with the inspection control unit it is stopped by KSE-U.
2 With a permanent pen, apply a mark onto each STM and the traction shaft.
3 Move the car down about five meters and up again to the previous position.
4 Check how much the marks on the STMs deviate from the mark on the traction
shaft.
– If the deviation is smaller than 30 mm (KZU 2:1) respectively 15 mm (KZU
1:1), no action required.
– If the deviation is greater than 30 mm (KZU 2:1) respectively 15 mm (KZU
1:1), check the STM for dirt and oil and, after cleaning, with a dry cloth.
Then repeat the test.
Contact the second level field support if the second test also is not satisfactory.
5 Call the car from the top landing.
6 Check the stopping accuracy to be within ± 10 mm.
7 If the stopping accuracy is greater than 10 mm, check the STM for dirt and oil
and, after cleaning, with a cloth. Then carry out the test once more.
8 Move the empty car with the inspection control and stop it in the upper part of
the hoistway.
9 Check that the stopping distance has not been extended by an STM slip.
