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. These
include the network cycle time, a control’s processing time and the response times of
downstream contactors, for example.
►
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
