SICK miniTwin4 User Manual

4.3.5.1 Using beam coding
Important information
DANGER
Hazard due to lack of effectiveness of the protective device
Different beam codings only prevent mutual interference if both safety light curtains are
of type miniTwin4.
b
In the case of systems in close proximity that are of a different type, take different
measures to prevent mutual interference.
Using beam coding
Use suit
able beam codings to prevent mutual interference from neighboring systems.
b
Configure one safety light curtain with code 1 and the other safety light curtain
with code 2.
The system automatically performs the coding. As soon as a system is influenced by
another system with an identical code, a fault occurs. During the next power-up, the
code is converted and operation is no longer possible.

Figure 19: Trouble-free operation due to beam coding
In t
he figure, the beam coding of systems in close proximity to each other is different.
The system with code 2 is not affected by the beams of the system with code 1.
4.4 Integrating the equipment into the electrical control
Overview
T
his chapter contains important information about integration in the electrical control.
Information about the individual steps for electrical installation of the device: see "Elec‐
trical installation", page 60.
Requirements for use
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 safety relays or a safety controller, for
example.
DANGER
H
azard 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 safety light curtain can fulfill its protective function.
