Safety notices
NOTICE
Observe the ESD guidelines
When handling and installing the devices, observe the ESD guidelines.
Connection is only permitted when the power adapters have been deactivated.

3TK2810-1 safety-related speed monitor
Equipment Manual, 05/2020, NEB926246402000/RS-AE/007 13

ESD guidelines
ESD components are destroyed by voltage and energy far below the limits of human perception.
Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not
electrostatically discharged. ESD components which have been subject to such voltage are
usually not recognized immediately as being defective, because the malfunction does not occur
until after a longer period of operation.
NOTICE
Damage to the speed monitor from electrostatic charging!
The speed monitor contains electrostatically sensitive devices. These modules will be
destroyed or damaged by improper handling.
• You must discharge your body electrostatically immediately before touching an electronic
component. To do this, touch a conductive, grounded object, e.g., a bare metal part of a
switch cabinet or the water pipe.
• Always hold the component by the plastic enclosure.
• Electronic modules should not be brought into contact with electrically insulating materials
such as plastic 󹪝lm, plastic parts, insulating table supports or clothing made of synthetic
󹪝bers.
• Always place electrostatic sensitive devices on conductive bases.
• Always store and transport electronic modules or components in ESD-safe conductive
packaging, e.g. metallized plastic or metal containers. Leave the component in its
packaging until installation.
Note
In the case of capacitive or inductive load at the output contacts, su󹪟cient suppressor circuits
must be provided to protect against contact overload. A fuse must also be connected in series
to protect against welding of the safety contacts (see Chapter "Technical data (Page 71)").
Note
Routing of the sensor cables
If electromagnetic interferences are to be expected, all initiator/encoder cables must be shielded
when laid. The shielding must be connected to PE at both ends.

Intended use
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 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 "Con󹪝guring (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 ful󹪝lls the regulations/
speci󹪝cations 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 󹪝rst 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.

Equipment Manual, 05/2020, NEB926246402000/RS-AE/007 15

Encoder
NOTICE
Use of encoders
In order to achieve the highest possible SIL/PL when using encoders, 2-channel encoders (4
tracks: A, A/, B, B/) with de󹪝ned failure response (high-impedance outputs) must be used.
If such information cannot be found on the encoder manufacturer's data sheet, then the failure
response data must be requested from the encoder manufacturer.
No speci󹪝c safety encoders have to be used on the 3TK2810-1 safety-related speed monitor.
If an encoder is used, the encoder's FIT (Failure in Time) value must be incorporated into the
calculation of the safety chain.
Encoders that are operated on a 3TK2810-1 safety-related speed monitor must have the
following properties:
• TTL/HTL encoders that provide two signal tracks with the respectively inverted signals.
• All sin/cos encoders that supply both the sine and the cosine tracks with the respectively
inverted signals (sin, /sin and cos, /cos).
• The phase o󹪜set of the two signals A (or sin) and B (or cos) must be 90 °, between A and /A
or B and /B it must be 180 ° in each case.
• The encoder's signals must have a high resistance in the event of failure.
The 3TK2810-1 speed monitor detects a disrupting o󹪜set of the signal track or mutual
overtaking of the signals in the case of sin/cos encoders. Detection of the fault is independent
of the set frequency. The 3TK2810-1 safety-related speed monitor assumes the safe state and
issues a fault message.
It is the responsibility of the user to check whether a speci󹪝c encoder and its pin assignments
match the 3TK2810-1 safety-related speed monitor.

Note
To achieve SILCL 2/3 as per IEC 62061 or PL d/e as per EN ISO 13849‑1, a fault exclusion such as
a short-circuit to P or M is required. This can, for example, be implemented within a control
cabinet or by installing the connection cables in such a way that they are protected. If this is not
possible, the actuators must be wired via two safety-related outputs, see image "Dual-channel
actuator wiring via two terminals". For this purpose, separate cables must be laid to actuators /
contactors.
