About this document
This document is valid for all safety switches CES-AP-C.2-AH with version number
V 1.1.2 or higher.
Correct use
The Coded Electronic Safety switches of series CES are safety devices for moni-
toring 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 Only components may be used that are permissible in accordance with the
table below.
