2. Correct use
Safety switches series CES-AH-C03-AE-LS are interlocking devices without guard locking (type 4). The device meets the
requirements according to EN IEC 60947-5-3, except for section 8.6. Devices with unicode evaluation possess a high
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
Devices in the system family CES-AH... have special safety outputs that are suitable for the direct switching of large loads.
In appropriate applications it is therefore not necessary to connect power relays or contactors in between.
The device interrupts the supply of power to the load, if, e.g., the guard is open.
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
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.
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.
