K Approach speed with which the object to be detected is nearing the danger zone in
mm/s
K = 1600 mm/s when S > 500 mm
K = 2000 mm/s when S ≤ 500 mm
t

Overall response time of the safety laser scanner in seconds (see Calculation of the
overall response time [ 34])
Time between the violation of a protective zone and signal change at the OSSD out-
put on the safety laser scanner
t
2
Machine's stopping time in seconds
The time required for the machine to stop after the signal at the OSSD output
changes
C Additional distance depend on the detection capability d
C = 8(d-14 mm) with d ≤ 40 mm
C = 850 mm/s with d > 40 mm

R
Allowance when installing near intense light sources or reflective surfaces (see Dis-
tance to intense light sources and to reflective surfaces [ 40])
5.2 Calculation of the overall response time
The overall response time results from the response time t1 (see Technical
details [ 115]), an allowance of 30ms t
multiple
for each scan>2 and with a series connec-
tion an allowance of 10ms per slave.

Each further increase of the multiple evaluation by 1 increases the allowance T

5.3 Switching of zone sets
For each zone set, a unique combination of signals must be defined at the control inputs.
To prevent unintended switching of the monitored zone sets, two consecutive zone sets
must differ in at least two positions in the assigned signals at the control inputs.
In the PSENscan Configurator the automatic assignment ensures a difference in exactly
two positions.
Pilz recommends that the automatic assignment by the PSENscan Configurator is used.
