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 in accordance with:
EN ISO 13489-1, Safety of machinery. Safety related parts of control systems.
General principles for design
EN ISO 1411-1, Safety of machinery. Risk assessment. Principles
IEC 6061, 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, in particular
EN ISO 13489-1, Safety of machinery. Safety related parts of control systems.
General principles for design
EN 1088, Safety of machinery. Interlocking devices associated with guards.
Principles for design and selection
EN 6004-1, Safety of machinery. Electrical equipment of machines. General
requirements
EN 60947-5-3 Specification for low-voltage switchgear and controlgear. Con-
trol circuit devices and switching elements. Requirements for proximity devices
with defined behaviour under fault conditions (PDF)
The safety switches CES-A-W5... are only allowed to be operated in conjunction
with the designated actuators and the related connection cable from EUCHNER.
On the use of a different actuator or another connection cable, EUCHNER provides
no warranty for safe function.
Important!
The devices are intended for use in safety circuits and, together with
connected evaluation units, permit safety functions according to
DIN EN ISO 13849-1: 008-1 - Table 8, such as a safety-related stop func-
tion, prevention of unexpected start-up, etc.
The safety-related function of the PDF is switch-off (low) of one of the
outputs (LA, LB) when the actuator is absent.
The user is responsible for safe integration of the device in a safe overall
system. For this purpose the overall system must be validated, e.g. in accor-
dance with EN ISO 13849-.
The permissible operating parameters must be observed for correct use
(see Technical data).
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.
Only components may be used that are permissible in accordance with the
table below. 
