3 Product description
3.1 Structure and function
The deTem2 Core Ex II 3GD multiple light beam safety device is an electro-sensitive pro‐
tec
tive 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 multiple light beam
safety 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 dan‐
gerous 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 be
am 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 sc
anning range is the maximum dimension of the light path between sender and
receiver. It depends on the device variant.

Persons and parts of the body to be protected may not be recognized in case of non-
observance.
b
Make sure that the following design requirements are met so that the multiple
light beam safety device 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
Ha
zard 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.
b
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 Minimum distance from the hazardous point
A minimum distance must be maintained between the multiple light beam safety
dev
ice 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 stan‐
dards 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, see "Technical data", page 52
•
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

ional information is available in the ISO 13855 standard and in the Guidelines

4.3.2 Minimum distance from reflective surfaces
Overview
T
he li
ght 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, verti‐
cal, and diagonal directions as well as at the ends of the multiple light beam safety
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.

zard 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.
b
Make sure that all reflective surfaces and objects maintain a minimum distance
from the light beams.
b
Make sure that no dispersive media (e.g., dust, fog, or smoke) are within the calcu‐
lated minimum distance from the light beams.
Determining minimum distance to reflective surfaces
The minimum dis
tance can be determined as follows:
1. Determine the distance between the sender and receiver D in meters (m).
2. Locate the minimum distance a in millimeters (mm) on the graph, or calculate it
using the appropriate formulatable 1:

The infrared light beams of the sender of system 1 can interfere with the receiver of
system 2. This can disrupt the protective function of system 2. This would mean that
the operator is at risk.
Avoid such installation situations or take appropriate action, e.g., install optically
opaque partitions or reverse the direction of transmission of a system.

The output signals of the protective device must be analyzed by downstream controllers
in such a way that the dangerous state of the machine is ended safely. Depending on
the safety concept, the signal is analyzed by, e.g., safety relays or a safety controller.
DANGER
Ha
zard 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.
b
Make sure that the following control and electrical requirements are met so that
the multiple light beam safety device can fulfill its protective function.
•
It must be pos
sible to electrically influence the control of the machine.
•
The electrical control of the machine must meet the requirements of IEC 60204-1.
•
Depending on the regulations which apply at the place of installation, a restart
interlock may be required. Because the multiple light beam safety device does not
have this function, it must be implemented in the external control if required.
•
When using a safety controller, different signal levels of both OSSDs must be
detected depending on the regulations which apply at the place of installation or
the required reliability of the safety function. The maximum discrepancy time toler‐
ated by the control must be selected according to the application.
•
The OSSD1 and OSSD2 output signals must not be connected to each other.
•
In the machine controller, the signals of both OSSDs must be processed sepa‐
rately.

T
he mac
hine must switch to the safe state at any time if at least one of the two
OSSDs switches to the OFF state.
