Mounting Procedures for COMPACT Light Curtains (Series C14 and C30)

With the COMPACT light curtains for finger and hand protection, it shall be observed that access to
the protection zone is not possible from above, below or around, as well as from stepping over the
curtain, by the incorporation of additional mechanical safeguards or by cascading the COMPACT
units.
The minimum clearance for protection is calculated as follows:
S = (K x T) + C
where:
S Minimum clearance between protection zone and hazard location, in mm (S
K Accessing rate 2 mm/ms
T Overtravel time of the machine + the response time of the optoelectronic protection device
(AOPD), in ms
C 8 (d - 14 mm), not less than 0 however
d Detection capacity (resolution) of the AOPD, in mm
If this calculation gives a value for S which is greater than 500 mm, then the calculation shall be
repeated for K = 1.6 mm/ms. In this case the value of S
