Installation Instructions KSW-2R

1. Description

The rope guard is intended for indirect measurement of the tensile force in ropes. For example at the fixed end of a rope.

The output signal is depend from the characteristic of rope and assembly. Deviations from the factory setting are possible!

(1) Open the hex nuts from the rope clamp jaw and remove it. Then loose the four hex nuts and remove the two guard plates.

(2) Place the KSW on the cable with the cable output downwards.

(3) Mount the upper rope clamp with the two hex nuts. Tighten the two hex nuts evenly until the cable reaches the lower rope clamp.

(4) Check the position of KSW-2R at the rope!

 The KSW-2R should not be damaged by the hook of the rope rolls. If necessary, correct the position of the KSW-2R on the rope.

 The rope must press during measurements on both rolls and on the bottom rope clamp.

 Especially with new ropes can be expected with a twist at the first load cycles.

In this case, the position of the cable must be selected.
