WARNING
Intended use
Can Cause Death, Serious Injury, or Property Damage.
The devices may only be used for the applications described in the catalog and the
technical description (see Chapter "Application (Page 14)"), and only in conjunction with
equipment or com
ponents from other manufacturers which have been approved or
recommended by Siemens. You must also ensure that suitable and reliable sensors are
used (see Chapter "Basic versions (Page 15)" and "Configuring (Page 48)").
T
his product
can function correctly and reliably only if it is transported, stored, assembled,
and mounted correctly, and operated and maintained as recommended.
Before you run any sample programs or programs that you have written yourself, make
sure that running the plant cannot cause injury to anyone else or damage to the machine
itself.
EU notice: Start-up/commissioning is absolutely prohibited until it has been ensured that
the machine in which the component described here is to be installed fulfills the
regulations/specifications of Machinery Directive 2006/42/EC.
Dormant error detection
Note
In the case of longer standstill times (t>= 24hrs), forced dormant error detection must be
carried out before restarting the system (function test of the application).
Exception:
This forced dormant error detection procedure is not necessary when using NAMUR
sensors.
Connection of the initiators
Note
If common sensor potentials are directly connected to the initiators and a common return
wire is connected to the 3TK2810-1 device, the first error that occurs will result in a loss of
the safety function. Thus the maximum achievable SIL = 1 and the PL = c.
A series connection of proximity switches is not permitted.
