Safety information and Maintenance
(Part of the Operating Instructions for Safety System CES-AR)
Subject to technical modifications; no r
esponsibility is accepted for the accuracy of this information. © EUCHNER GmbH + Co. KG v091181-07-05/13 (translation of the original operating instructions)
EN Correct Use
The Coded Electronic Safety switches series CES are
safety devices for monitoring movable safety guards.
In combination with a separating safety guard and
the machine control, this safety component prevents
dangerous machine movements from occurring while
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 assessment
must be performed on the machine, e.g., in accor-
dance with:
f
EN ISO 13489-1, Safety of machinery. Safety re-
lated parts of control systems. General principles
for design
f
EN ISO 12100, Safety of machinery – General
principles for design – Risk assessment and risk
reduction
f
IEC 62061, Safety of machinery – Functional safety
of safety-related electrical, electronic and program-
mable electronic control systems.
Correct use includes compliance with the relevant re-
quirements for installation and operation, for example
f
EN ISO 13489-1, Safety of machinery. Safety re-
lated parts of control systems. General principles
for design
f
EN 1088, Safety of machinery. Interlocking devices
associated with guards. Principles for design and
selection
f
EN 60204-1, Safety of machinery. Electrical equip-
ment of machines. General requirements
f
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)
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.
Connection of several devices in a CES-AR switch
chain is permitted only using devices intended for
series connection with the CES-AR. Check this in the
system manual for the related device. A combination
of other CES devices or devices from other manufac-
turers is not allowed.
A maximum of 20 safety switches CES-AR are allowed
to be operated in series.
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.
In the case of the series connection of up to 20
CES-AR devices, the Performance Level is PL e.
In the case of series connections of up to 11 de-
vices, the PFH
d
is 2.64 x 10 -8
In the case of series connections of more than
11 devices, the PFH
d
can be calculated according to
one of the stated methods in EN ISO 13849-1:2008,
section 4.5.1.
If the simplified method according to section 6.3
EN ISO 13849:2008-12 is used for validation, the
Performance Level (PL) may be reduced if several
devices are connected one after the other.
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 instructions
are not followed, or if any servicing is not performed
as required, liability will be excluded and the war-
ranty void.
General Safety Instructions
The device is only allowed to be installed and placed
in operation by authorized personnel
f
who are familiar with the correct handling of safety
components,
f
who are familiar with the applicable regulations on
health and safety
f
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.
Prior to use, read the operating instructions on the
CD/DVD supplied, and keep these in a safe place.
Ensure the operating instructions are always avail-
able during mounting, setup and servicing.
EUCHNER cannot provide any warranty in relation
to the readability of the CD/DVD for the storage
period required. For this reason you should archive
a printed copy of the operating instructions. You
can download the operating instructions at www.
EUCHNER.de.
Operating instructions on CD/DVD
Each device is supplied with operating instructions
on CD/DVD; these instructions contain detailed
information on the overall system. The following
system requirements must be met to be able to
open or print the document:
f
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
a PDF Reader that can open PDF files from version 4.
1. Insert CD/DVD
¨ Selection table is opened in the browser
2. Click the related document for your system
¨ The document is opened and can be printed
Mounting, setup and troubleshooting
For detailed instructions on mounting, setup and
troubleshooting, please refer to the operating
instructions on the CD/DVD.
Electrical connection
For detailed information on the electrical connec-
tion, please refer to the operating instructions on
the CD/DVD.
Important: To achieve the stated category accord-
ing to EN ISO 13849, both safety outputs must
always be evaluated.
Do not use a control system with pulsing or switch
off the pulsing function in your control system.
Take note of the connection example in the operating
instructions on CD/DVD.
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.
Only accessories or spare parts that can be ordered
from EUCHNER may be replaced.
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
f
Check the switching function
f
Check the secure fastening of the devices and the
connections
f
Check for soiling (e.g. the ventilation slots on the
housing)
Check the safe function of the safety guard par-
ticularly
f
after any setup work
f
after the replacement of a CES component
f
after an extended period without use
No servicing is required. Repairs to the device are only
allowed to be made by the manufacturer.
