SICK nanoScan3 I/O

nanoScan3 Core I/O nanoScan3 Pro I/O
Pulse duration Typ. 4 ns
Average output power 12.8 mW
Laser class 1
3)
Measurement error with mea‐
sur
ement data output
Typ. ± 25 mm
1)
In the event of heavy contamination, the safety laser scanner displays a contamination error and
s
witches all safety outputs to the OFF state.
2)
In close proximity (50 mm wide area in front of the optics cover), the detection capability of the safety
laser scanner may be restricted. If required, this area must be secured using an undercut or frame, for
example.
3)
This laser product has laser class 1 according to IEC 60825-1:2014. In some cases, evaluation is
required according to the older IEC 60825-1:2007 standard, e.g. by employers in the EU according to
Directive 2006/25/EC. According to the older IEC 60825-1:2007 standard, laser class 1M must be used
as the basis.
13.3 Response times
Overview
T
he protective device’s response time is the maximum time between the occurrence of
the event leading to the sensor’s response and supply of the switch-off signal to the
protective device’s interface (for example OFF state of the OSSD pair).
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.
Response time
T
he safety laser scanner’s response time depends on the set multiple sampling.
You can calculate the response time using the following formula:
t
R
= n × 30 ms +10 ms
The following rules apply:
•
t
R
= response time
•
n = set multiple sampling (default: n = 2)
13.4 Course of the OSSD test over time
The safety laser scanner tests the OSSDs at regular intervals. To do this, the safety
la
ser scanner switches each OSSD briefly to the OFF state and checks whether this
channel is voltage-free during this time.
Make sure that the machine’s control does not react to these test pulses and the
machine does not switch off.
