6.1.5 Resolution and safety distance for fixed and floating blanking as well as reduced resolution
Resolution and safety distance when using the “Fixed blanking” function
The calculation of the safety distance must always be based on the effective resolution. If the effective
resolution deviates from the physical resolution, this must be documented near the protective device on
the supplied sign in a lasting, wipe-resistant manner.
Table 6.3: Effective resolution and additional distance to the safety distance during fixed blanking
with
1 beam size tolerance for access guarding in accordance with EN ISO 13855 when
approaching the protective field orthogonally.
Resolution, response time and safety distance when using the “Floating blanking” function
Table 6.4: Effective resolution and additional distance to the safety distance during floating blanking
for point of operation guarding in accordance with EN ISO 13855 when approaching the
protective field orthogonally
Due to the operating principle, floating blanking extends the response time. This must be taken into
account when calculating the safety distance. Additional time t
FB
to the response time is dependent on the
number of beams in the largest beam area with floating blanking or the length of protective field area L
FB
and is calculated according to the following:

WARNING
Faulty application of blanking functions may result in serious injury!
 Note that the additional distances to the safety distance may require additional measures be taken for
preventing stepping behind.
