Operating Instructions Safety System CES-A-.5
Correct Use
The Coded Electronic Safety switches series CES
are safety devices for monitoring movable safety
guards.
In combination with a separating safety guard, this
safety component prevents dangerous machine
movements from being performed for as long as the
safety guard is open. A stop command is triggered
if the safety guard is opened during the dangerous
machine function.
Before safety switches are used, a risk assess-
ment must be performed on the machine, e.g., in
accordance with:
EN ISO 13489-1, Safety of machinery. Safety re-

lated parts of control systems. General principles
for design
EN ISO 14121, Safety of machinery. Risk assess-

ment. Principles
IEC 62061, Safety of machinery – Functional

safety of safety-related electrical, electronic and
programmable electronic control systems.
Correct use includes compliance with the relevant
requirements for installation and operation, for
example
EN ISO 13489-1, Safety of machinery. Safety re-

lated parts of control systems. General principles
for design
EN 1088, Safety of machinery. Interlocking

devices associated with guards. Principles for
design and selection
EN 60204-1, Safety of machinery. Electrical equip-

ment of machines. General requirements
EN 60947-5-3, Specification for low-voltage switch-

gear and controlgear. Control circuit devices and
switching elements. Requirements for proximity
devices with defined behaviour under fault condi-
tions (PDF)
In general, the following applies for devices with
ATEX rating:
EN 60079-0, Electrical apparatus for potentially

explosive atmospheres
EN 60079-15, Electrical apparatus for explosive

gas atmospheres -- Part 15: Type of protection
"n"
EN 61241-0, Electrical apparatus for use in the

presence of combustible dust
EN 61241-1, Electrical apparatus for use in the

presence of combustible dust -- Part 1: Protection
by enclosures "tD"
The safety switch must be used only in conjunction
with the designated actuators from EUCHNER. On
the use of different actuators, EUCHNER provides
no warranty for safe function.
Devices with ATEX rating may only be operated
with actuators that also have an ATEX rating for
the same zone.
Important: The user is responsible for the integra-
tion of the device in a safe overall system. For this
purpose, the overall system must be validated, e.g.
in accordance with EN ISO 13849-2.
If a product data sheet is included with the product,
the information on the data sheet applies in case of
discrepancies with the operating instructions.

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
The device is only allowed to be installed and placed
in operation by authorized personnel
who are familiar with the correct handling of safety

components,
who are familiar with the applicable regulations

on health and safety
and who have read and understood the operating

instructions and the system manual.
The safety function of the system while the machine
is in operation can no longer be ensured if the
device is connected incorrectly or used incorrectly.
Fatal injuries may result.
Prior to use, read the operating instructions and
the system manual on the CD-ROM supplied, and
keep these in a safe place.
Ensure the operating instructions and the system
manual 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 system manual. If you should
lose the operating instructions or the system
manual, you can download these documents from
www.EUCHNER.de.
System manual on CD-ROM
Each device is supplied with a system manual on
CD-ROM; this manual contains detailed informa-
tion on the overall system. The following system
requirements must be met to be able to open or
print the manual:
PC with PDF Reader installed

CD-ROM drive

Opening and printing the documents

Important: the autoplay function for the drive must
be enabled (see operating system help) and you
will need a PDF Reader that can open PDF files
from version 4.
1. Insert CD
Selection table is opened in the browser

Mounting, setup and troubleshooting
For detailed instructions on mounting, setup
and troubleshooting, please refer to the system
manual.

Electrical Connection

For detailed information on the electrical connection,
please refer to the system manual.
Important: To achieve the stated category accord-
ing to EN ISO 13849, both safety outputs must
always be evaluated with individual devices.
Take note of the connection example in the system
manual.
Inspection and Service
Danger: Loss of the safety function because of
damage to the system. In case of damage, the
related component must be replaced completely.
Replacement of individual parts of a component (e.
g. parts of the evaluation unit) is not permitted.
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
Check the switching function

Check the secure fastening of the devices and

the connections
Check for soiling (e.g. the ventilation slots on the

housing)
Check the safe function of the safety guard par-
ticularly
after any setup work

after the replacement of a CES component

after an extended period without use

No servicing is required. Repairs to the device are
only allowed to be made by the manufacturer.
