10.7 Retracted Detector Slides
Between the roller engaged and the slanting edges of the slide notches, there must be a visible play
as shown in Figure 15. For the adjustment of the detector rods, the point blades attached to them
must be in the closed end position each, i.e. the rods are set separately.
Figure 15
Retracted detector slides
In the closed end position of the point blade, the contact lever roller must be able to engage with the
small notch of the associated detector slide. By adjusting the length of the detector rod, move the
detector slide to a position which ensures a distance "a" between roller and slanting edge of the slide
notch. Adjust the distance at mean annual temperature, taking into account the changes in length of
the detector rod caused by temperature variations.
The distance between roller and slanting edge of the large slide notch varies as a function of the point
opening. However, it must be so small that the detection contact breaks before the point lock reaches
its minimum clamp overlap when the open point blade leaves the end position.
Distance "a" can be set between 0 mm and 6 mm.
It depends on the type and layout of points and
the specifications of the points' manufacturer.
