DANGER
H
azard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
In addition to the protective device’s response time, further signal transmission and
processing also influence the time up until the end of the dangerous state. This
includes a control’s processing time and the response times of downstream contactors,
for example.
b
Take the time for further signal transmission and processing into account.
Response time
T
he safety laser scanner’s response time depends on the following parameters:
•
Scan cycle time
•
Set interference protection
•
Set multiple sampling
You can calculate the response time using the following formula:
t
R
= (t
S
+ t
I
) × n + t
O
The following rules apply:
•
t
R
= response time
•
t
S
= scan cycle time
°
Setting “30 ms”: t
S
= 30 ms
°
Setting “40 ms”: t
S
= 40 ms
•
t
I
= time for interference protection
°
Mode 1 (default): t
I
= 0 ms

Mode 2: t
I
= 1 ms

Mode 3: t
I
= 2 ms

Mode 4: t
I
= 3 ms

n = set multiple sampling
Preset to n = 2.
Multiple sampling can be changed for the safety laser scanner or for each individ‐
ual f
ield (2 ≤ n ≤ 16).
