3 Product description
3.1 Setup and function
Overview
The deTem4 Core A/P safety multibeam scanner is an electro-sensitive protective
device (ESPE) consisting of a sender and receiver unit (hereinafter referred to as the
active unit) and a deflection unit (hereinafter referred to as the passive unit). The
sender and receiver unit is located in the same housing.
The hazardous area is protected by the infrared light beams between the active unit
and the passive unit on the opposite side. The infrared beams of the active unit hit the
passive unit and are sent back to the active unit with a parallel offset.
When one or more light beams are completely interrupted, the protective device reports
the interruption in the light path to the secure output signal switching devices (OSSDs)
by a signal change. The machine or its control must safely analyze the signals (for
example using a safe control or safety relays) and stop the dangerous state.
Figure 1: Active and passive units
Beam separation and number of beams
The beam separation is the distance between two adjacent light beams, measured
from the center of one beam to the center of the next.
The beam separation and number of beams depend on the device variant.

Scanning range
The scanning range is the maximum dimension of the light path between active and
passive units.
Depending on the passive unit used, a small or large scanning range can be achieved.
The scanning range is reduced by using a weld spark guard.

3.2.3 Near Field Communication (NFC)
Overview
The active unit of the safety multibeam scanner has an integrated NFC interface for
transmitting diagnostic data of the protective device to an NFC-capable device.
The integrated NFC interface is intended for temporary use.
Diagnostic data
The following diagnostic data can be displayed in an NFC-capable device:
•Device information and device status, e.g. name, serial number, type code, status
of OSSDs, or quality of alignment
•Fault diagnosis with specification of the error code, error description, diagnostic
LED and troubleshooting
An NFC-capable antenna is integrated behind the front screen of the safety multibeam

DANGER
Hazard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
bMake sure that the optical properties of the front screens of the active and
passive units for small scanning ranges are not changed, e.g. by:
°beading water, mist, frost, or ice formation. If applicable, remove films or
other types of contamination, disconnect the voltage supply of the active unit
and then switch it back on.
°Scratches or damage. Replace the device if the front screen is scratched or
damaged.
bMake sure that all reflective surfaces and objects maintain a minimum distance
from the light beams.
bMake sure that no dispersive media (e.g., dust, fog, or smoke) are within the

DANGER
Hazard due to lack of effectiveness of the protective device
Certain types of light radiation can influence the protective device, e.g., light radiation
from fluorescent lamps with electronic ballast installed in the path of the beam, or
beams from laser pointers directed at the active unit.
bIf this type of light radiation is present in the environment of the protective device,
take additional measures to ensure that the protective device does not become
dangerous.

Calculating the minimum distance according to ISO13855
The calculation of the minimum distance is based on international or national stand‐
ards and statutory requirements applicable at the place of installation of the machine.
If the minimum distance is calculated according to ISO 13855, then it depends on the
following points:
•Machine stopping time (time interval between triggering the sensor function and
the end of the machine’s dangerous state)
•Response time of the protective device
•Approach speed of personnel
•Type of approach:orthogonal (at right angles)
•Parameters specified based on the application
For the USA (scope of OSHA and ANSI), different regulations may apply, e.g.:
a) Laws: Code of Federal Regulations, Title 29 (CFR29) Part 1910.217
b) Standards: ANSI B11.19
Complementary information
Additional information is available in the ISO 13855 standard and in the Guidelines
Safe Machinery.
SICK offers a stopping/run-down time measurement service in many countries.

4.3.2.1 Calculating minimum distance from the hazardous point
Important information
DANGER
Minimum distance from the hazardous point is too small
The dangerous state of the machine may not be stopped or not be stopped in a timely
manner due to a minimum distance that is too small.
bCalculate the minimum distances for the machine in which the safety multibeam
sensor is integrated.
bWhen mounting the safety multibeam sensor, observe the minimum distance.
Approach
The example shows the calculation of the minimum distance for an orthogonal (at right
angles) approach to the safety multibeam sensor. Depending on the application and
the ambient conditions, a different calculation may be required (e.g., at a different
angle to the direction of approach or an indirect approach).
1. Calculate S using the following formula:
S = 1,600mm/s × T + C
where:
°S =minimum distance in millimeters (mm)
°T = machine stopping time + response time of the protective device after
interruption in the light path in seconds (s)
°C = supplement in accordance with ISO 13855:
•If it is not possible to reach over the protective device: C = 850mm
•If it is possible to reach over the protective device, the value CRO must be
used for C in accordance with ISO 13855, provided that this is greater
than 850mm: C ≥850mm and C ≥CRO

3Depending on the application and distance, persons must be prevented from standing
behind the protective device.
Example calculation
Machine stopping time = 290ms
Response time after interruption of the light path = 20ms
T = 290ms + 20ms = 310ms = 0.31s
S = 1,600mm/s × 0.31s + 850mm = 1,346mm
4.3.3 Minimum distance from reflective surfaces
Overview
The light beams from the active unit may be deflected by reflective surfaces and
dispersive media. This can prevent an object from being detected.
Therefore, all reflective surfaces and objects (e.g., material bins, machine table, etc.)
must maintain a minimum distance (a) from the light beams. This minimum distance
(a) must be maintained on all sides of the light beams. This applies in horizontal,
vertical and diagonal directions as well as at the end of the protective device. The same
area must be free of dispersive media (e.g., dust, fog, or smoke).
The minimum distance (a) depends on the distance (D) between active and passive
unit.

DANGER
Hazard due to lack of effectiveness of the protective device
Reflective surfaces and dispersive media can prevent persons or parts of the body to
be protected from being properly reflected and therefore, they remain undetected.
bMake sure that all reflective surfaces and objects maintain a minimum distance
from the light beams.
bMake sure that no dispersive media (e.g., dust, fog, or smoke) are within the
calculated minimum distance from the light beams.
bMake sure that there are no reflective surfaces behind the passive unit outside
the maximum scanning range of 8m (system with 2beams) or 7m (system with
4beams) that could cause beam deflection.
Determining minimum distance to reflective surfaces
1. Determine the distance between active and passive units (D) in meters (m)
2. Read the minimum distance (a) in millimeters (mm) in the graph or calculate it
based on the respective formula from table 5:
