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:
Ì
EN ISO 13489-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì
EN ISO 14121-1, Safety of machinery. Risk assessment. Principles
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, in particular

Important!
Ì
The devices permit a safety-related stop function, initiated by a safety guard
according to Table 8 - DIN EN ISO 13849-1: 2008-12.
Ì
The safety-related function of the PDF is the opening of at least one
of the output contacts (13/14, 23/24) when the actuator is absent.
Ì
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 13849-2.
Ì
The permissible operating parameters must be observed for correct use
(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.
