6.2 Calculation of the overall response time
The overall response time results from the response time t1 (see Technical
details [ 127]), an allowance of t
multiple
for each additional detection required for multiple
evaluation>2 and for a series connection an allowance of t
Subscriber
per subscriber.

Allowance of 10 ms per subscriber
In a multiple evaluation=3 the allowance is T

=30 ms.
Each further increase of the multiple evaluation by 1 increases the allowance T
multiple
by30
ms.
6.3 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.
