2. Correct use
The AR evaluation unit is used for the central evaluation of safety-related signals in AR switch chains.
The following applies in combination with a CES switch:
In combination with a movable guard and the machine control, this system 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 12100 or relevant C-standards.
The following applies in combination with a CET/CTP switch:
In combination with a movable guard and the machine control, this system prevents the guard from being opened
while a dangerous machine function is being performed.
This means:
Ì
Starting commands that cause a dangerous machine function must become active only when the guard is closed
and locked.
Ì
The guard locking must not be released until the dangerous machine function has ended.
Closing and locking a guard must not cause automatic starting of a dangerous machine function. A separate start
command must be issued. For exceptions, refer to EN 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
Only safety switches that are suitable for operation in an AR switch chain can be evaluated. Check the operating instructions
for the related safety switch. Combination with devices that are not suitable for use in an AR switch chain or with devices
from other manufacturers is not permitted. A maximum of 12 safety switches in an AR switch chain can be connected to
the AR evaluation unit
CES-AR-AES-12
. However, at least 2 switches must be connected.
Unicode and multicode version switches can be connected. Unicode and multicode versions can be combined in an AR
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.
