Intended use
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 23)"), and only in conjunction with equipment or
components 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 24)" and "Configuring (Page 57)").
This 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 case of longer standstill times (t >= 24 h), a start-up test (function test of the application) is
absolutely necessary before restarting the system.
Exception:
Such a startup test 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.
