Operating Instructions ESL
Correct use
The safety system ESL is an interlocking device without guard locking.
In combination with a safety guard, this safety component prevents dangerous
machine movements from being performed for as long as the safety guard is
opened. A stop command is triggered if the safety guard is opened during the
dangerous machine function.
Before safety switches are used, a risk assessment must be performed on the
machine, e.g. in accordance with:
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì EN ISO 12100, Safety of machinery - General principles for design - Risk as-
sessment and risk reduction
Ì IEC 62061, Safety of machinery. Functional safety of safety-related electrical,
electronic and programmable electronic control systems.
Correct use includes compliance with the relevant requirements for installation
and operation, for example
Important!
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì 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. General
requirements
Ì EN 60947-5-3, Specification for low-voltage switchgear and controlgear. Con-
trol circuit devices and switching elements. Requirements for proximity devices
with defined behavior under fault conditions
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. A combination with other ESL devices or devices from other manufacturers
is not allowed.
A maximum of 20 devices are allowed to be operated in a switch chain.
Ì The user is responsible for the 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 Correct use requires observing the permissible operating parameters (see
Technical data).
Ì If a product data sheet is included with the product, the information on the
data sheet applies in case of discrepancies with the operating instructions.
Ì In the estimation of the PL for the overall system, a maximum value of
100 years can be assumed for the MTTFd according to the limit value in
EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value
for the PFHd of 2.47x10-8/h.
Ì When up to 11 devices are connected in series, these limit values can be
assumed for the entire switch chain as a subsystem. As a subsystem, this
switch chain achieves PL e.

Important!
Ì In the case of series connection of more than 11 devices, the PFH
calculated according to one of the stated methods in EN ISO 13849-1:2008,
Section 4.5.1.
Ì If the simplified method according to section 6.3 of EN ISO 13849:2008-12
is used for validation, the Performance Level (PL) might be reduced when
more than 11 devices are connected in series.
Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or
if the safety instructions are not followed, or if any servicing is not performed as
required, liability will be excluded and the warranty void.

General safety instructions
Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly
Ì after any setup work
Ì each time after the replacement of an ESL module
Ì after an extended period without use
Ì after every fault
Independent of these checks, the safe function of the safety guard should be
checked at suitable intervals as part of the maintenance schedule.
Warning!
Danger of fatal injury in the event of incorrect connection or incorrect use.
Ì Safety switches must not be bypassed (bridging of contacts), turned away,
removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the pos-
sibility of bypassing from EN 1088:1995+A2:2008, section 5.7.
The switching operation may be triggered only by the handle module ESL-H...
designated for this purpose.
The device is only allowed to be installed and placed in operation by authorized
personnel
Ì who are familiar with the correct handling of safety components
Ì who are familiar with the applicable EMC regulations
Ì who are familiar with the applicable regulations on health and safety and ac-
cident prevention
Ì who have read and understood the operating instructions.
Function
Important!
Prior to use, read the operating instructions and keep these in a safe place.
Ensure the operating instructions are always available during mounting, setup
and servicing work. EUCHNER cannot provide any warranty in relation to the
readability of the CD for the storage period required. For this reason you should
archive a printed copy of the operating instructions. If you should lose the operating instructions, you can download this document from www.EUCHNER.de.
Together with a handle module, the interlocking module makes it possible to interlock movable safety guards. The combination also serves as a mechanical door
stop at the same time.
The interlocking module detects the position of the closure and thereby the position
of the safety guard.

Changing the connection
The plug connector position can be adapted to suit the installation. This change
must be performed before assembly.
1. Press the plug connector with the plastic inserts out of the profile slot.
¨ To adjust only the cable exit for angled plug connectors, align the plug and the
inserts accordingly and press the plug back into the profile slot.
2. Remove the connection cap on the opposite side.
3. For angled plug connectors, align the plug and the inserts accordingly.
4. Press the plug into the profile slot on the opposite side.
5. Seal the other opening with the connection cap.

Mounting
Caution!
Ì The device is not suitable for use on sliding doors.
Ì When mounting, take care not to trap the cables between the device and the
profile.
Ì Permanently connect the actuator and handle module to the safety guard so
that it cannot be detached, e.g. using non-removable screws.
Important!
Ì When mounting different transponder-coded safety switches, observe the
stipulated minimum distance to avoid mutual interference.

With two-wing hinged doors, one of the two door wings additionally must be latched
mechanically.
1. Fasten the ESL using 4 M6 screws and washers.
¨ Please note that the gap dimension between handle module and interlocking
module is 0 - 3 mm; the max. vertical offset is ± 1 mm.
2. Tighten the screws to a torque of max. 10 Nm.
3. Fit the enclosed cover caps to protect against tampering.
