2. Correct use
Safety switches series CTP-L.-… are interlocking devices with guard locking solenoid (type 4). 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.
Connection of several devices in an AR switch chain is permitted only using devices intended for series connection in an AR
switch chain. Check this in the instructions of the device in question.
A maximum of 20 safety switches are allowed to be operated in a 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.
