Correct use
The Coded Electronic Ssafety switch series CES are a type series of technical
safety devices for monitoring moveable separating 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 13849-1, 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
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.

For further information, refer to the operating instructions of the corresponding
component and to the following table Possible combinations for CES components.
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 the output
contacts (13/14, 23/24) when the actuator is absent.
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
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.
