β = Door opening angle
C = Door width in mm
D is the door gap in mm with an overlap at B = 0 mm.
B is the thickness of the door
The actual door gap "D1" is calculated using door gap "D" calculated by
means of the table above minus the overlapping "B" of door and frame:
D1 = D – B

Example:
A door made of 40 mm aluminium profile with a length of 950 mm
should be secured with a TESK. The safety contact of the TESK opens
to 3° when new according to the technical safety sheet (10° at the end
of its service life). The table above shows the door gap when new at ap-
prox. 49.7 mm. The real door gap can be calculated with the following
equation D1 = D – B; (49.7 – 40 = 9.7); D1 = 9.7 mm. At the end of the
service life the door gap is approx. 164.9 mm and the real door gap is
(164.9 – 40 = 124.9); D1 = 124.9 mm.
