2. Correct use
Safety switches series CES-A-C5H-EX are interlocking devices without guard locking (type 4). The device meets the require-
ments according 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 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
Ì EN ISO 12100
Ì IEC 62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì EN ISO 13849-1
Ì EN ISO 14119
Ì EN 60204-1
Ì DIN EN 1127-1
Ì EN 60079-0
Ì EN 60079-7
Ì EN 60079-14
Ì EN 60079-31
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 Devices with ATEX rating may be operated only with actuators that also have an ATEX rating for
the same zone.
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.
