About this document
Please read these operating instructions carefully before using the SKS36S/
SKM36S safe motor feedback system or mounting it, putting it into operation or
servicing it.
This document is a translation of the original document.
1.1 Purpose of this document
These operating instructions are for giving technical personnel of the machine
manufacturer or operator instructions on the safe assembly, electrical installation,
commissioning, operation and maintenance of the SKS36S/SKM36S safe motor
feedback system.
In addition, for planning and using protective equipment such as the SKS36S/
SKM36S safe motor feedback system, technical skills are required that are not
covered by this document.
The official and legal regulations for operating the SKS36S/SKM36S safe motor
feedback system must always be complied with.
1.2 Symbols used
WARNING
Indicates a situation presenting possible danger, which may lead to death or
serious injuries if not prevented.
NOTICE
Indicates a situation presenting possible danger, which may lead to property
damage if not prevented.

On safety
WARNING
In addition, observe the safety instructions and warnings in the documenta‐
tion of the drive system connected.
2.1 Skilled persons
The SKS36S/SKM36S safe motor feedback system may be mounted, put into
operation, checked, serviced and used by skilled persons only.
A skilled person
•
has taken part in adequate technical training
and
•
has been instructed by the machine operator in machine operation and the
applicable safety guidelines
and
•
can access these operating instructions.
2.2 Field of use for the device
The safety-related use of the SKS36S/SKM36S safe motor feedback system with
sine/cosine output applies to its use in combination with servo systems with
three-phase AC synchronous motors. Their commuting information and (rota‐
tional) speed information is derived from the sine/cosine signals of the encoder
connected directly to the motor shaft. These can also be used with servo systems
working with asynchronous motors, where the speed control is derived from the
sine/cosine signals from the encoder directly connected to the motor shaft.
The SKS36S/SKM36S safe motor feedback system can be used in combination
with a drive system as per IEC 61800-5-2, for safety applications up to control cat‐
egory 3 as per EN ISO 13849, SILCL2 as per EN 62061 or up to PL d as per EN
ISO 13849.
It meets the requirements of machinery directive 2006/42/EC and is for support‐
ing the drive system in ensuring
•
the safety functions, based on the reliable speed information of the motor
feedback system
2.3 Intended use
SKS36S/SKM36S safe motor feedback system may only be used in the manner
defined in Chapter .
The safe motor feedback system may be used only in terms of the “Scopes of
application of the device” chapter and within the limits of the prescribed and
specified technical data, dimensions and tolerances of the dimensional drawings
and operating conditions, and the specified tightening torques must be complied
with.
It is especially important that the motor feedback system not be used for safety
applications beyond its mission time and bearing service life (see technical data).
After its bearing service life is exceeded, bearing wear or fatigue could lead to
bearing failure. To prevent this, the motor feedback system must be taken out of
operation no later than when the bearing service life has been reached.
The bearing service life is also influenced by the specific application, in particular
due to operating modes with low speeds, reversing operation and mechanical
vibrations.
Current should be prevented from passing through the ball bearing (e.g. due to
injected currents).
If used in any other way or if alterations are made to the device – including in the
context of assembly and installation – this will render warranty claims void
directed to SICK STEGMANN GmbH.
2.4 General safety instructions and protective measures
WARNING
Observe the following to ensure the safe use of the SKS36S/SKM36S safe
motor feedback system as intended.
•
The national and international legal specifications apply to the installation
and use of the SKS36S/SKM36S safe motor feedback system, to its com‐
missioning and to technical inspections repeated at regular intervals, in par‐
ticular:
–
the machinery directive 2006/42/EC
–
the use of work equipment directive 2009/104/EC
–
the accident prevention regulations and safety regulations
–
and any other relevant safety regulations
•
The manufacturer and operator of the machine on which the SKS36S/
SKM36S safe motor feedback system is used are responsible for coordinat‐
ing and complying with all applicable safety specifications and regulations, in
cooperation with the relevant authorities.
•
The manufacturer of the drive system connected must have complied with
the safety requirements for the drive system design described in the imple‐
mentation manual, "Hiperface Safety".
•
These operating instructions must be made available to the operator of the
machine on which the SKS36S/SKM36S safe motor feedback system is
used. The machine operator must be instructed by skilled personnel and
read the operating instructions.
