Operating Instructions
Safety Systems with Locking ESL-IH-AR
EN
2. Correct use
Safety systems series ESL-AR are interlocking devices without guard locking (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 eval-
uation possess a low coding level.
In combination with a movable safety guard and the machine control, this safety component prevents dangerous machine
functions from occurring while the safety guard is open. A stop command is triggered if the safety 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 safety guard is closed.
Ì
Opening the safety guard triggers a stop command.
Ì
Closing a safety 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, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì
EN ISO 12100, Safety of machinery – Basic concepts – General principles for design – Risk assessment and risk reduc-
tion
Ì
IEC 62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable electronic
control systems
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
Ì
EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì
EN ISO 14119 (supersedes EN 1088), Safety of machinery – Interlocking devices associated with guards – Principles
for design and selection
Ì
EN 60204-1, Safety of machinery – Electrical equipment of machines.
The safety system ESL can only be combined with the intended modules in the ESL system family.
On the modification of system components, EUCHNER provides no warranty for function.
Several devices are only allowed to be connected in series using devices intended for series connection with the ESL.
Check the operating instructions for the related device. Combination with devices from other manufacturers is not allowed.
A maximum of 20 devices 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.
