2. Correct use
Safety switches series CES-I-BR are interlocking devices without guard locking (type 4). The device meets the requirements
according to EN IEC 60947-5-3. Devices with unicode evaluation possess a high coding level, devices with multicode eval-
uation possess a low coding level.
In combination with a movable guard and the machine control, this safety component prevents dangerous machine functions
from occurring while the guard is open. A stop command is triggered if the guard is opened during the dangerous machine
function.
This means:
Ì
Starting commands that cause a dangerous machine function must become active only when the guard is closed.
Ì
Opening the guard triggers a stop command.
Ì
Closing a guard must not cause automatic starting of a dangerous machine function. A separate start command must
be issued. For exceptions, refer to EN ISO 12100 or relevant C-standards.
Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following
standards:
Ì
EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì
EN ISO 12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
Ì
IEC 62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable electronic
control systems.
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì
EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì
EN ISO 14119, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
Ì
EN 60204-1, Safety of machinery – Electrical equipment of machines.
The safety switch is only allowed to be operated in conjunction with the intended EUCHNER CES actuators and the related
connection components from EUCHNER. On the use of different actuators or other connection components, EUCHNER
provides no warranty for safe function.
Connection of several devices in a BR switch chain is permitted only using devices intended for series connection in a BR
switch chain. Check this in the instructions of the device in question.
A maximum of 20 safety switches are allowed to be operated in a switch chain.
Important!
Ì
The user is responsible for the proper integration of the device into a safe overall system. For this
purpose, the overall system must be validated, e.g. in accordance with EN ISO 13849-2.
Ì
It is only allowed to use components that are permissible in accordance with the table below.
