Safety Information

(Part of the Operating Instructions Evaluation Units CMS-E-.R)
Scope
This safety information is part of the operating
instructions for evaluation units CMS
Correct use
Evaluation units series CMS are technical safety
devices for monitoring movable safety guards.
Special read heads are connected for this purpose.
The system consists of evaluation unit, read head
and actuator. It forms a non-contact, magnetically
coded interlocking device with low coding level
(type 4).
In combination with a safety guard, this system
prevents dangerous machine functions from being
performed for as long as the safety guard is opened.
A stop command is triggered if the safety guard is
opened during the dangerous machine function.
This means:
Starting commands that cause a dangerous ma-
f
chine function must become active only when the
safety guard is closed.
Opening the safety guard triggers a stop com-
f
mand.
Closing the safety guard must not cause auto-
f
matic starting of a dangerous machine function.
A separate start command must be issued. For
exceptions, refer to EN ISO 12100 or relevant
C-standards.
Before safety components are used, a risk assess-
ment must be performed on the machine, e.g. in
accordance with the following standards:
EN ISO 13849-1, Safety of machinery – Safety-re-
f
lated parts of control systems – Part 1: General
principles for design
EN ISO 12100, Safety of machinery – General
f
principles for design – Risk assessment and risk
reduction
EN 62061, Safety of machinery – Functional
f
safety of safety-related electrical, electronic and
programmable electronic control systems.
Correct use includes observing the relevant require-
ments for installation and operation, e.g. according
to the following standards:
EN ISO 13849-1, Safety of machinery – Safety-re-
f
lated parts of control systems – Part 1: General
principles for design
EN ISO 14119 (supersedes EN 1088), Safety of
f
machinery – Interlocking devices associated with
guards – Principles for design and selection
EN 60204-1, Safety of machinery. Electrical equip-
f
ment of machines. General requirements
Important!
The evaluation unit must be used only in con-
f
junction with the designated read heads and
actuators from EUCHNER. On the use of different
read heads or actuators, EUCHNER provides no
warranty for safe function.
The devices permit a safety-related stop function,
f
initiated by a safety guard according to Table 8
- EN ISO 13849-1: 2015.
The safety-related function of the safety system
f
is the opening of the output contacts (13/14,
23/24) when the actuator is absent.
The user is responsible for safe integration of
f
the device into a safe overall system. For this
purpose, the overall system must be validated,
e.g. in accordance with EN ISO 13849-2.
Correct use requires observing the permissible
f
operating parameters (see technical data).
If a product data sheet is included with the prod-
f
uct, the information on the data sheet applies
in case of discrepancies with the operating
instructions.
Only components may be used that are permissi-
f
ble in accordance with the following combination
options table. Refer to the operating instructions
of the corresponding component for further
information.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety instruc-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
General safety instructions
Safety components fulfill personal protection
functions. Incorrect installation or tampering can
lead to severe injuries to personnel.
Check the safe function of the safety guard
particularly
after any setup work
f
each time after replacement of a CMS component
f
after an extended period without use
f
after every fault
f
Independent of these checks, the safe function
of the safety guard should be checked at suitable
intervals as part of the maintenance schedule.
For information about possible time intervals, refer
to EN ISO 14119: 2013, section 8.2.
Warning!Danger of fatal injury in the event of
incorrect connection or incorrect use.
Safety components must not be bypassed (bridg-
ing of contacts), turned away, removed or other-
wise rendered ineffective. Pay particular attention
to EN ISO 14119: 2013, section 7, regarding the
possibilities for bypassing an interlocking device.
The auxiliary contact 23/24 on the CMS-E-BR must
not be used as a safety output.
The auxiliary contact 31/32 on the evaluation
units CMS-E-ER/CMS-E-FR must not be used as a
safety contact.
The device may be installed and put into operation
only by authorized personnel,
who are familiar with the correct handling of
f
safety components
who are familiar with the applicable EMC reg-
f
ulations
who are familiar with the applicable regulations
f
on operational safety and accident prevention
who have read and understood the operating
f
instructions.
Important!
Prior to use, read the operating instructions and
keep these in a safe place. Ensure the operating
instructions are always available during mounting,
setup and servicing. EUCHNER cannot provide any
warranty in relation to the readability of the CD for
the storage period required.
For this reason you should archive a printed copy
of the operating instructions. You can download
the operating instructions from www.euchner.com.

Operating instructions on CD/DVD
Each device is supplied with operating instructions
on CD/DVD, which contain detailed information on
the overall system. The following system require-
ments must be met to be able to display or print
the document:
PC with PDF reader installed
f
CD/DVD drive
f
Opening and printing the documents
Important: The autoplay function for the drive must
be enabled (see operating system help), and you will
need an up-to-date PDF reader.

Mounting, setup and
troubleshooting
For detailed instructions on mounting, setup and
troubleshooting, please refer to the operating
instructions on the CD/DVD.
Caution! The evaluation unit must be mounted
in a control cabinet with a minimum degree of
protection of IP 54. A snap-in element on the rear
of the device is used for fastening to a mounting
rail. If several evaluation units are mounted side
by side in a control cabinet without air circulation
(e.g. fan), a minimum distance of 10 mm must
be maintained between the evaluation units.This
distance enables the heat from the evaluation unit
to dissipate.
Caution! Risk of damage to equipment as a result
of incorrect installation. Read heads or actuators
must not be used as a mechanical end stop.Fit
an additional end stop for the movable part of the
safety guard.
Important! From the assured switch-off distance
s , the safety outputs are safely shut down.If the
ar
actuator is installed flush, the switching distance
changes as a function of the installation depth and
the safety guard material.
Electrical connection
For detailed information on the electrical connec-
tion, please refer to the operating instructions on
the CD/DVD.
WARNING
In case of an error, loss of the safety function
through incorrect connection.
Lay the connection cables with protection to
f
prevent the risk of short circuits.
Service and inspection
No servicing is required. Regular inspection of
the following is necessary to ensure trouble-free
long-term operation:
correct switching function
f
secure mounting of components
f
loose connections.
f
In the event of damage or wear and tear, the dam-
aged system component must be replaced.
If the safety door is not frequently used, the system
must be subjected to a regular function test as part
of the inspection schedule.
