2. Correct use
Safety switches series CTP-L1/2-… and CTA-L1/2-… are interlocking devices with guard locking solenoid (type 4). The
device meets 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 command
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 a BR switch chain is permitted only using devices intended for series connection in a BR
switch chain. Check this in the instructions of the device in question.
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.
