Guard Opening Calculation (before switching)
The size opening between the machine frame and the guard can be estimated based on the table provided. This can assist in
determining safety distance as described by ANSI B11.19 or ISO 13857.
Example
A guard with a 40 mm aluminum profile (A) and a width of 900 mm (B) is safeguarded by SI-HG(Z)63 safety interlocking switch. The
switching point is set (fixed) while guard is closed, the positive-opening switching point is set at α = 6° in the opening direction
(assuming that the point has not been finely-adjusted).
In the table, find the "B" row of "900" and then follow over to the 6° column and note the number (94.1 mm). The approximate
opening in the guard at the switching point (C1) can be found by subtracting the width of the guard.
C1 = C – A = 94.1 mm – 40 mm = 54.1 mm
(at initial installation).
where:
α = Opening angle of the guard at the point of switching
A
= Width of the guard in mm
B
= Length of the guard in mm
C
= Distance travel by outside of guard
C1
= Size of the opening in the guard at the point of switching
