3 Product description
3.1 Setup and function
The deTem2 Core multiple light beam safety device is an electro-sensitive protective
vice (ESPE) consisting of a sender and receiver.
de
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.
PRODUCT DESCRIPTION 3
Figure 1: Sender and receiver
Beam separation and number of beams
T
he 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
T
he scanning 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.
Make sure that the following design requirements are met so that the multiple
b
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
azard due to lack of effectiveness of the protective device
H
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,
b
take additional measures, if required, 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
vice and the hazardous point. This distance is required to prevent a person or part of
de
the body from reaching the hazardous area before the dangerous state of the machine
state has completed.

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.
Calculate the required minimum distance for your machine.
b
Mount the multiple light beam safety device taking this calculation into account.
b
Calculating minimum distance
he calculation of the minimum distance is based on international or national stand‐
T
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:
16
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 49
•
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.:

Reflective surfaces and dispersive media can prevent persons or parts of the body to

The light beams from the sender may be deflected by reflective surfaces and dispersive

media
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.

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 opa‐
que partitions or reverse the direction of transmission of a system.

t be possible 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.

OSSDs switches to the OFF state.
Prevent the formation of a potential difference between the load and the protec‐

tive device. If you connect loads to the OSSDs (output signal switching devices)
that then also switch if controlled with negative voltage (e.g., electro-mechanical
contactor without reverse polarity protection diode), you must connect the 0 V con‐
nections of these loads and those of the corresponding protective device individu‐
ally and directly to the same 0 V terminal strip. In the event of a fault, this is the
only way to ensure that there can be no potential difference between the 0 V con‐
nections of the loads and those of the corresponding 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.
Downstream contactors must be positively guided and monitored depending on appli‐
cable national regulations or required reliability of the safety function.
Make sure that downstream contactors are monitored (external device monitoring,
b
EDM).
ause the multiple light beam safety device does not have integrated external

device monitoring, this must be implemented in the external control, if required.
