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:
ÌStarting commands that cause a dangerous machine function must become active only when the safety guard is closed.
ÌOpening the safety guard triggers a stop command.
ÌClosing 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:
ÌENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
ÌENISO12100, Safety of machinery – Basic concepts – General principles for design – Risk assessment and risk reduc-
tion
ÌIEC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:
ÌENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
ÌENISO14119 (supersedes EN1088), Safety of machinery – Interlocking devices associated with guards – Principles
for design and selection
ÌEN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 modication 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!
ÌThe 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.
ÌIt is only allowed to use components that are permissible in accordance with the table below.

3. Description of the safety function
Devices from this series feature the following safety functions:
Monitoring of the safety guard position
(interlocking device according to ENISO14119)
ÌSafety function:
- The safety outputs are switched off when the safety guard is open (see chapter 6.3. Switching states on page 8).
ÌSafety characteristics: category, Performance Level, PFHd(see chapter 11. Technical data on page 23).
4. 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.
5. General safety instructions
Safety systems fulll personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly
Ìafter any setup work
Ìafter the replacement of a system component
Ìafter an extended period without use
Ìafter 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 to life due to improper installation or due to bypassing (tampering). Safety components perform
a personal protection function.
ÌSafety components must not be bypassed, turned away, removed or otherwise rendered ineffec-
tive. On this topic pay attention in particular to the measures for reducing the possibility of bypass-
ing according to ENISO14119:2013, section 7.
ÌThe switching operation may be triggered only by handle modules designated for this purpose.
ÌPrevent bypassing by means of replacement handle modules (only for multicode evaluation). For
this purpose, restrict access to handle modules and to keys for releases, for example.
ÌMounting, electrical connection and setup only by authorized personnel possessing the following
knowledge:
- specialist knowledge in handling safety components
- knowledge about the applicable EMC regulations
- knowledge about the applicable regulations on occupational safety and accident prevention.
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. 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. You can download the operating instruc-
tions from www.euchner.de.

6. Function
The safety system ESL-AR monitors the position of movable safety guards. The safety outputs are switched on/off when the
latch on the handle module is moved to/removed from the operating distance on the interlocking module.
The interlocking module detects the position of the latch and thereby the position of the safety guard. The combination also
serves as a mechanical door stop at the same time.
Whether the device learns the complete handle module code (unicode) or not (multicode) depends on the respective version.
ÌDevices with unicode evaluation:The handle module must be assigned to the interlocking module by a teach-in oper-
ation so that it is detected by the system. This unambiguous assignment ensures a particularly high level of protection
against tampering. The system thus possesses a high coding level.
ÌDevices with multicode evaluation:Unlike systems with unique code detection, on multicode devices a specic code
is not requested but instead it is only checked whether the handle module is of a type that can be detected by the sys-
tem (multicode detection). There is no exact comparison of the handle module with the taught-in code in the interlocking
module (unique code detection). The system possesses a low coding level.
When the safety guard is closed, the handle module is moved toward the interlocking module. When the switch-on distance
is reached, power is supplied to the handle module by the interlocking module and data is transferred.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the safety guard is opened.
In the event of a fault in the interlocking module, the safety outputs are switched off and the DIA LED illuminates red. The
occurrence of faults is detected at the latest on the next demand to close the safety outputs (e.g. on starting).
6.1. Components
The system consists of the following components: coded handle module (transponder) and interlocking module.
Interlocking module
LED indicator
Handle module
Closure
Lock
6.2. Door monitoring output

7. Mounting
CAUTION
Safety systems must not be bypassed (bridging of contacts), turned away, removed or otherwise
rendered ineffective.
ÌObserve ENISO14119:2013, section 7, for information about reducing the possibilities for by-
passing an interlocking device.
ÌThe device is not suitable for use on sliding doors.
ÌWhen mounting, take care not to trap the cables between the device and the prole.
ÌPermanently connect the interlocking module and handle module to the safety guard so that they
cannot be detached, e.g. using non-removable screws.
NOTICE
Risk of damage to equipment and malfunctions as a result of incorrect installation.
ÌWhen mounting several transponder-coded safety switches, observe the stipulated minimum dis-
tance to avoid mutual interference.

1. Press the plug connector with the plastic inserts out of the prole 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 prole 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 prole slot on the opposite side.
5. Seal the other opening with the connection cap.
