and function as interlocking devices without guard locking (type 4). The device meets the requirements ac-
cording to EN IEC 60947-5-3. Devices with unicode evaluation possess a high coding level, devices with multicode evaluation
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 safety switches are used, a risk assessment must be performed on the machine, e.g., in accordance with:
Ì
EN ISO 13849-1
Ì
EN ISO 12100
Ì
IEC 62061
Correct use includes observing the relevant requirements for installation and operation, e.g.
Ì
EN ISO 13849-1
Ì
EN ISO 14119
Ì
EN 60204-1
The safety switch must be used only in conjunction with the designated CES actuators from EUCHNER. On the use of different
actuators, EUCHNER provides no warranty for safe function.
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
Correct use requires observing the permissible operating parameters (see technical data).
Ì
If a data sheet is included with the product, the information on the data sheet applies.
Ì
It is only allowed to use components that are permissible in accordance with the table below.
