About this document

This document is valid for all safety switches CES-AP-C01-CH with version number

V 0.1.2 or higher.

Correct use

The Coded Electronic Safety switches series CES are safety devices for monitor-

ing 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 accordance with:

Ì

EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.

General principles for design

Ì

EN ISO 12100, Safety of machinery – General principles for design – Risk as-

sessment and risk reduction

Ì

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

Ì

EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.

General principles for design

Ì

EN 1088, Safety of machinery. Interlocking devices associated with guards.

Principles for design and selection

Ì

EN 60204-1, Safety of machinery. Electrical equipment of machines. General

requirements

Ì

EN 60947-5-3, Specification for low-voltage switchgear and controlgear. Con-

trol circuit devices and switching elements. Requirements for proximity devices

with defined behavior under fault conditions

The safety switch must be used only in conjunction with the designated CES ac-

tuators from EUCHNER. On the use of different actuators, EUCHNER provides no

warranty for safe function.

Important!

Ì

The user is responsible for the integration of the device into a safe overall
system. For this purpose, the overall system must be validated, e.g. in ac-
cordance with EN ISO 13849-2.

Ì

In the estimation of the PL for the overall system, a maximum value of
100 years can be assumed for the MTTF

d

according to the limit value in

EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value
for the PFH

d

of 2.47x10

-8

/h.

Ì

Correct use requires observing the permissible operating parameters (see
Technical data).

Ì

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.

Ì

It is only allowed to use components that are permissible in accordance with
the table below.
