7.2.4 Safety mode with restart interlock during the hazardous movement "B1"
e.g. For applications with manual cyclic penetrations of the protective field during a non-hazardous movement or machine
standstill.

Functional example
Having switched on the safety facility, the protective field must
be penetrated in order to carry out a startup test. Having
subsequently pressed the start button with the protective field
free, the output contacts 16-17 and 20-21 close and the
machine movement is started.
If the protective field of the light barrier is penetrated during
the hazardous movement, the contacts 16-17 and 20-21 are
opened and the machine stopped.
The checking path 6-7 is used to perform an additional check
of the hydraulic valves or the contactor. The activation of a new
operating stroke or a hazardous movement will only be
performed if both or valves K1 and K2 had fallen when the
protective field, and the protective field is subsequently free
again.
During the idling status of the operating materials, or during a
non-hazardous opening movement (opened switch "S"), its is
possible to access the operating materials at any time without
having to press the start button.
When activating the closing movement via contactors K1 and
K2, the respective make contacts of K1 and K2 must be
switched in series!
In this operating mode, it must be ensured that it
is not possible to walk behind the light barrier!

7 Additional functions with safety switchgears
- "B1"
LSUW NSR 3-1 K switchgear
Cable routing:
- Separately from power lines.
- The cable routing for the contactor
check (terminals 6 & 7) must prevent
short-circuiting of wires.
- On terminals 4, 5, 8, 9, the max. cable
length is limited to <= 1m.
The hazardous movement must
only be activated via output
contacts 16-17 and 20-21.
The output contacts are
potential-free, monitored, guided
make contacts are must be
loaded with max. 2 A/250 VAC
or 60 VDC, 30 W. With inductive
load, the load (not the contacts)
is to be switched at the same
time as the spark arresting
sections (e.g. 0.22 uF, 220
Ω
.
Optional power supply:
The contact 18 - 19 serves as an
alarm path and is not permitted
to activate the hazardous closing
movement.
To increase the switching
reliability, collateral contacts
should be used on terminals 5,
6, 7, 8, 9, 10, 11, D and 22. No
external potential must be
connected to these terminals.
When performing electric
welding work on the machine,
the terminal strip of the
switchgear is to be removed,
otherwise the vagrant welding
currents may cause destruction
of the installed electronics.
