The position of the closed point blade is always detected allowing small deviations only (small slide
notch). When the contact lever roller touches the slanting edge of the notch, the detection circuit is
interrupted after a slide stroke of max. 1.5 mm. The open point blade must reach its end position
within the tolerance of ± 8 mm, referring to the slide stroke set (large slide notch). If the point blades
move beyond their end positions, a point fault indication is issued.
If the connection between a point blade and the end position detector is broken, carrier 15 provides a
slide position the next time the points are reversed which prevents the indication "point position OK"
from being issued.
Stop pin 21 prevents the detector slides from being pulled out of the area detected by contact
arrangement 2.
