3 Product description
3.1 Setup and function
Overview
The deTem4 Core Ex safety multibeam sensor is an electro-sensitive protective device
(ESPE) consisting of a sender and receiver.
Parallel infrared light beams between the sender and receiver protect the hazardous
area. When one or more light beams are completely interrupted, the safety multibeam
sensor 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.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.
Figure 1: Sender and receiver
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 sender and
receiver.
The scanning range is reduced by using deflector mirrors.

4.3 Design
Overview
This chapter contains important information about the design.
Important information
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.
►Make sure that the following design requirements are met so that the safety
multibeam sensor can fulfill its protective function.
°Sender and receiver must be arranged such that persons or parts of the body
are reliably detected when they enter the hazardous area.
°Ensure that nobody can pass under the lowest light beam, pass over the
highest light beam, get between two light beams, or pass by the side of the
protective device.
°If people can stay between the protective device and the hazardous point
without being detected, check if additional protective measures (e.g., restart
interlock) are required.

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 receiver.
►If 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.

4.3.1 Scanning range and beam separation
Important information
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.
►The safety multibeam sensor can only be mounted on machines where the dimen‐
sion of the light path does not change when the device is switched on.
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 sender and
receiver. It depends on the device variant.
The scanning range is reduced by using deflector mirrors.

4.3.2 Minimum distance from the hazardous point
A minimum distance must be maintained between the safety multibeam sensor and
the hazardous point. This distance is required to prevent a person or part of the body
from reaching the hazardous area before the dangerous state of the machine state has
completed.
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.
►Calculate the minimum distances for the machine in which the safety multibeam
sensor is integrated.
►When 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
The reach/approach speed is already included in the formula.

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 sender 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 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 sender and receiver.

Figure 7: Minimum distance from reflective surfaces
Important information
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.
►Make sure that all reflective surfaces and objects maintain a minimum distance
from the light beams.
►Make sure that no dispersive media (e.g., dust, fog, or smoke) are within the
calculated minimum distance from the light beams.
Determining minimum distance to reflective surfaces
The minimum distance can be determined as follows:
►Determine the distance between sender and receiver D in meters (m).
►Read the minimum distance a in millimeters (mm) in the graph or calculate using
the respective formula to determine the minimum distance to reflective surfaces:
