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:
ÌEN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
ÌEN ISO 12100, Safety of machinery - General principles for design - Risk as-
sessment and risk reduction
ÌIEC 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
ÌEN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
ÌEN 1088, Safety of machinery. Interlocking devices associated with guards.
Principles for design and selection
ÌEN 60204-1, Safety of machinery. Electrical equipment of machines. General
requirements
ÌEN 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.
Important!
ÌThe 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 ac-
cordance with EN ISO 13849-2.
ÌCorrect use requires observing the permissible operating parameters (see
Technical data).
ÌIf a product data sheet is included with the product, the information on the
data sheet applies in case of discrepancies with the operating instructions.
ÌIn the estimation of the PL for the overall system, a maximum value of
100 years can be assumed for the MTTFdaccording to the limit value in
EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value
for the PFHdof 2.47x10-8/h.
ÌWhen 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.

Operating Instructions ESL

Important!
ÌIn the case of series connection of more than 11 devices, the PFHdcan be
calculated according to one of the stated methods in EN ISO 13849-1:2008,
Section 4.5.1.
ÌIf 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 tam-
pering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly
Ìafter any setup work
Ìeach time after the replacement of an ESL module
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 of fatal injury in the event of incorrect connection or incorrect use.
ÌSafety 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
Ìwho are familiar with the correct handling of safety components
Ìwho are familiar with the applicable EMC regulations
Ìwho are familiar with the applicable regulations on health and safety and ac-
cident prevention
Ìwho have read and understood the operating instructions.
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 op-
erating instructions, you can download this document from www.EUCHNER.de.
Function
Together with a handle module, the interlocking module makes it possible to inter-
lock 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.

Mounting
Caution!
ÌThe device is not suitable for use on sliding doors.
ÌWhen mounting, take care not to trap the cables between the device and the
profile.
ÌPermanently connect the actuator and handle module to the safety guard so
that it cannot be detached, e.g. using non-removable screws.
Important!
ÌWhen 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.

Operating Instructions ESL

Electrical connection
The following connection options are available:
ÌSeparate operation
ÌSeries connection with Y-distributors from EUCHNER
ÌSeries connection, e.g. with wiring in the control cabinet.
Warning!
In case of an error, loss of the safety function through incorrect connection.
ÌTo ensure safety, both safety outputs (FO1A and FO1B) must always be eval-
uated.
ÌThe monitoring output OD must not be used as a safety output.
ÌLay the connection cables with protection to prevent the risk of short cir-
cuits.
Caution!
Risk of damage to equipment or malfunctions as a result of incorrect connection.
ÌDo not use a control system with pulsing or switch off the pulsing function in
your control system. The device generates its own clock signal on the output
lines FO1A/FO1B. A downstream control system must tolerate these test
pulses, which may have a length of up to 1 ms.
The pulses are also present when the safety outputs are switched off. De-
pending on the inertia of the connected device (control system, relay, etc.),
this can lead to short switching processes.
ÌThe inputs on an evaluation unit connected must be positive-switching, as the
two outputs on the safety switch deliver a level of +24 V in the switched-on
state.
ÌAll the electrical connections must either be isolated from the mains supply
by a safety transformer according to IEC EN 61558-2-6 with limited output
voltage in the event of a fault, or by other equivalent isolation measures.
ÌFor use and operation as per the requirements, a power supply with the
feature "for use in class 2 circuits" must be used. The same requirement
applies to the safety outputs.
Alternative solutions must comply with the following requirements:
a) Electrically isolated power supply unit with a max. open-circuit voltage of
30 V/DC and a limited current of max. 8 A.
b) Electrically isolated power supply unit in combination with fuse as per UL248.
This fuse should be designed for max. 3.3 A and should be integrated into
the 30 V DC voltage section.
ÌAll electrical outputs must have an adequate protective circuit for inductive
loads. The outputs must be protected with a free-wheeling diode for this pur-
pose.
ÌPower devices, which are a powerful source of interference, must be in-
stalled in a separate location away from the input and output circuits for
signal processing. The cable routing for safety circuits should be as far away
as possible from the cables of the power circuits.
ÌIn order to avoid EMC interference, the physical environmental and operating
conditions at the installation site of the device must comply with the require-
ments according to the standard EN 60204-1:2006, section 4.4.2 (EMC).
Important!
If the device does not appear to function when operating voltage is applied (e.g.
green STATE LED does not flash), the safety switch must be returned unopened
to the manufacturer.

Operating Instructions ESL
10
Safety in case of faults
ÌThe operating voltage UBis reverse polarity protected.
ÌThe contacts FI1A/FI1B and FO1A/FO1B are short circuit-proof
ÌA short circuit between FI1A and FI1B or FO1A and FO1B is detected by the
switch.
ÌA short circuit in the cable can be excluded by laying the cable with protection.
Fuse protection for power supply
The power supply must be provided with fuse protection depending on the number
of devices and current required for the outputs. The following rules apply:
Max. current consumption of an individual device Imax
Imax = IUB + IOD + IFO1A+FO1B
IUB = Switch operating current (max. 40 mA)
IOD = Monitoring output load current (max. 50 mA)
IFO1A+FO1B = Load current of safety outputs FO1A + FO1B (2 x max. 100 mA)
Max. current consumption of a switch chain ΣImax
ΣImax = IFO1A+FO1B + n x (IUB + IOD)
n = Number of connected devices
Requirements for connection cables
Caution!
Risk of damage to equipment or malfunctions as a result of incorrect connection
cables.
ÌUse connection components and connection cables from EUCHNER
ÌOn the usage of other connection components, the requirements in the fol-
lowing table apply. EUCHNER provides no warranty for safe function in case
of failure to comply with these requirements.
Observe the following requirements with respect to the connection cables:
Parameter Value Unit
Conductor cross-section min. 0.14 … 0.34 mm²
R max. 150 W/km

Determining cable lengths using the example table
Example: 6 devices are to be used in series. Cabling with a length of 40 m is
routed from a safety relay in the control cabinet to the last device (#6). Cables
with a length of 20 m each are connected between the individual ESL devices.

A safety relay is connected downstream which consumes 75 mA at each of the
two safety inputs. This operates over the whole temperature range with a voltage
of 19.2 V (corresponds to 24 V -20%).
All the relevant values can now be determined using the example table:
1. Select the corresponding section in the column n (max. number of devices).
Here: 6 switches.
2. In column IOD (possible output current per channel FO1A/FO1B), find a current
greater than or equal to 75 mA. Here: 100 mA.
¨The maximum cable length from the control system to the start of the switch
chain is listed in column l1. Here: a length of 50 m is permitted.
Result: The desired cable length l1of 40 m is below the permitted value from the
table. The overall length of the switch chain lmax of 140 m is less than the maximum
value of 200 m.
¨The planned application is therefore functional in this form.

If a single ESL is used, connect the device as shown in Figure 3. The OD output
can also be connected here to a control system as a monitoring output.
The device can be reset via the RST input. To do this, a voltage of 24 V is applied
to the RST input for at least 3 seconds. The supply voltage to the switch is inter-
rupted during this time. The RST input must be connected to 0 V if it is not used.

Connection of several ESL devices in an AR switch
chain
Important!
ÌA switch chain may contain a maximum of 20 safety switches.
ÌIn the estimation of the PL for the overall system, a maximum value of
100 years can be assumed for the MTTFdaccording to the limit value in
EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value
for the PFHdof 2.47x10-8/h.
The devices are connected in series using plug connectors and Y-distributors. If
a safety door is opened or if a fault occurs on one of the switches, the system
shuts down the machine. A higher level control system can, however, not detect
which safety door is open or on which switch a fault has occurred.
The switches can be reset via the RST input. To do this, a voltage of 24 V is applied
to the RST input for at least 3 seconds. The supply voltage to the switches is inter-
rupted during this time. The RST input must be connected to 0 V if it is not used.

Teach-in function for handle module (only ESL uni-
code)
The handle module must be assigned to the interlocking module using a teach-in
function before the system comprising interlocking module and handle module
forms a functional unit.
During a teach-in operation, the safety outputs are in high-resistance state, i.e. the
system is in the safe state.
When a handle module for which teach-in operation is possible is in the operating
distance, monitoring output OD indicates this with a HIGH signal.
Important!
ÌThe interlocking module disables the code for the previous handle module
if teach-in is carried out for a new handle module. Teach-in is not possible
again immediately for this actuator if a new teach-in operation is carried out.
The disabled code is deleted again in the interlocking module only after a
third code has been taught.
ÌThe interlocking module can only be operated with the last handle module
taught.
ÌThe interlocking module enters normal operation when it detects the taught
handle module after power up.
ÌIf the interlocking module detects a disabled handle module during teach-in
operation, it enters a fault state at the end of the teach-in operation.
ÌIf the closure is within the operating distance for less than 30 seconds, the han-
dle module is not taught in and the interlocking module enters the fault state.
Teaching in handle module
1. Fit handle module.
2. Close safety guard. Check for correct alignment and distance and readjust if
necessary.
3. Apply operating voltage to the interlocking module.
¨The green LED flashes quickly (approx. 5 Hz)
A self-test is performed during this time (approx. 8 s). Teach-in operation
starts, green LED flashes slowly (approx. 1 Hz). The teach-in operation is
ended after approx. 30 seconds and is positively acknowledged with an al-
ternating red/green flashing sequence.
4. To activate the handle module's code from the teach-in operation in the interlock-
ing module, the operating voltage must then be switched off at the interlocking
module for min. 3 seconds. As an alternative, 24V can be applied to the input
RST for min. 3 seconds.

Operating Instructions ESL
16
Mechanical function test
It must be possible to insert the closure easily into the interlocking module. Close
the safety guard several times to check the function.
Electrical function test
After installation and any fault, the safety function must be fully checked. Proceed
as follows:
Warning!
Danger of fatal injury as a result of faults in installation and functional check.
ÌBefore carrying out the functional check, make sure that there are no per-
sons in the danger area.
ÌObserve the valid accident prevention regulations.
1. Switch on operating voltage.
ÌThe interlocking module carries out a self-test.
The green STATE LED flashes for 8 s with 5 Hz.
The STATE LED then flashes at regular intervals.
2. Close all safety guards.
ÌThe machine must not start automatically.
ÌThe green STATE LED illuminates continuously.
3. Enable operation in the control system.
4. Open the safety guard.
ÌThe machine must switch off and it must not be possible to start it as long as
the safety guard is open.
ÌThe green STATE LED flashes at regular intervals.
Repeat steps 2-4 for each safety guard.

3) Corresponds to the risk time according to EN 60947-5-3. This is the maximum switch-off delay for the safety outputs after
pulling on the handle module.

Typical system times
Ready delay: After switching on, the unit carries out a self-test for 8 s. The system
is ready for operation only after this time.
Risk time according to EN 60947-5-3: If a handle module moves outside the
operating distance, the safety outputs FO1A and FO1B on the corresponding inter-
locking module are deactivated after a maximum of 260 ms. If more than one device
is used, the value increases correspondingly (see System times for switch chains).
Difference time: The safety outputs FO1A and FO1B switch with a slight delay
in relation to each other. They have the same signal state at the latest after a
difference time of 10 ms.

Important!
The system times shown are maximum values for a circuit arrangement with
20 safety switches connected in series. Shorter times can also be achieved in
circuits with fewer switches.
