2. Correct use
Safety switches series CTM-…-AS.. are operated as slaves on the safety bus AS-Interface Safety at Work and function
as interlocking devices with guard locking solenoid (type 4). The device complies with the requirements 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 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.
Ì
Closing and locking a guard must not cause automatic starting of a dangerous machine function. A separate start com-
mand must be issued. For exceptions, refer to EN ISO 12100 or relevant C-standards.
Devices from this series are also suitable for process protection.
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
The safety switch is allowed to be operated only in conjunction with the intended EUCHNER actuator and the related connec-
tion 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.
