Safety Information and Maintenance
(Part of the Operating Instructions for Safety Switch CES-A-.5)
Scope
This safety information is part of the operating
instructions for safety switch CES‑A‑.5 from version
number V0.1.2.
Correct use
Safety switches series CES‑A‑.5 are interlocking
devices without guard locking (type 4). The
device meets the requirements according to
EN IEC 60947‑5‑3. Devices with unicode evaluation
possess a high coding level, devices with multicode
evaluation possess a low coding level.
In combination with a movable guard and the
machine control, this safety component prevents
dangerous machine functions from occurring while
the guard is open. A stop command is triggered if
the 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
guard is closed.
Opening the guard triggers a stop command.
f
Closing a guard must not cause automatic starting
f
of a dangerous machine function. A separate start
command must be issued. For exceptions, refer to
EN ISO 12100 or relevant C‑standards.
Before the device is used, a risk assessment must
be performed on the machine, e.g. in accordance
with the following standards:
EN ISO 13849‑1
f
EN ISO 12100
f
IEC 62061
f
Correct use includes observing the relevant require‑
ments for installation and operation, particularly
based on the following standards:
EN ISO 13849‑1
f
EN ISO 14119
f
EN 60204‑1
f
The safety switch is only allowed to be operated
in conjunction with the intended EUCHNER CES
actuators and the related connection components
from EUCHNER. On the use of different actuators or
other connection components, EUCHNER provides
no warranty for safe function.
Important!
The user is responsible for the proper integration
f
of 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.
If a data sheet is included with the product, the
f
information on the data sheet applies.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety regula‑
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
General safety precautions
Safety switches fulfill personnel protection functions.
Incorrect installation or tampering can lead to fatal
injuries to personnel.
Check the safe function of the guard particularly
after any setup work
f
after the replacement of a system component
f
after an extended period without use
f
after every fault
f
Independent of these checks, the safe function of
the guard should be checked at suitable intervals
as part of the maintenance schedule.
WARNING
Danger to life due to improper installation or due
to bypassing (tampering). Safety components fulfill
a personnel protection function.
Safety components must not be bypassed, turned
f
away, removed or otherwise rendered ineffective.
On this topic pay attention in particular to the
measures for reducing the possibility of bypassing
according to EN ISO 14119:2013, section 7.
The switching operation must be triggered only
f
by actuators designated for this purpose.
Prevent bypassing by means of replacement
f
actuators (only for multicode evaluation). For this
purpose, restrict access to actuators and to keys
for releases, for example.
Mounting, electrical connection and setup only
f
by authorized personnel possessing the following
knowledge:
‑ specialist knowledge in handling safety com‑
ponents
‑ knowledge about the applicable EMC regulations
‑ knowledge about the applicable regulations
on operational safety and accident prevention.
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:

Mounting, setup and
troubleshooting
For detailed instructions on mounting, setup and
troubleshooting, please refer to the operating
instructions on the CD/DVD.
NOTICE
Risk of damage to equipment and malfunctions as
a result of incorrect installation.
Safety switches and actuators must not be used
f
as an end stop.
Observe EN ISO 14119:2013, sections 5.2 and
f
5.3, for information about mounting the safety
switch and the actuator.
Electrical connection
For detailed information on the electrical connec‑
tion, please refer to the operating instructions on
the CD/DVD.
WARNING
If there is a mistake, loss of the safety function
due to incorrect connection.
To ensure safety, both safety outputs must always
f
be evaluated.
Monitoring outputs must not be used as safety
f
outputs.
Lay the connecting cables with protection to
f
prevent the risk of short circuits.

Inspection and service
WARNING
Loss of the safety function because of damage
to the device.
In case of damage, the affected device 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:
Check the switching function
f
Check the secure mounting of the devices and
f
the connections
Check for soiling
f
No servicing is required. Repairs to the device are
only allowed to be made by the manufacturer.
