About this document
This document is valid for all safety switches CES-I-AR-M-C04.
Correct use
The Coded Electronic Safety switches series CES are safety devices for monitoring movable safety guards.
In combination with a separating safety guard and the machine control, this safety
component prevents dangerous machine movements from occurring while the
safety guard is open. 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
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 switch must be used only in conjunction with the designated CES actuators from EUCHNER. On the use of different actuators, EUCHNER provides no
warranty for safe function.
Connection of several devices in an AR switch chain is permitted only using devices
intended for series connection in an AR switch chain. Check this in the instructions
of the device in question.
A maximum of 20 safety switches are allowed to be operated in a switch chain.
Important!
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.

Important!
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.
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.
Ì It is only allowed to use components that are permissible in accordance with
the table below.

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 after the replacement of a CES component
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!
Loss of safety function 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 possibility of bypassing from EN 1088:1995+A2:2008, section 5.7.
Important!
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
Prior to use, read the operating instructions and keep these in a safe place. Ensure
that 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
instructions from www.EUCHNER.de.

Operating Instructions Safety Switch CES-I-AR-M-C04
Function
The device complies with the following safety requirements:
Ì Safety category 4, PLe according to EN ISO 13849-1
Ì Redundant design of the circuit in the unit with self-monitoring
Ì This means that the safety system still functions even if an internal component
fails
Ì The switch state of the semiconductor outputs is continuously monitored inter-
nally
Ì Short circuit detection at the safety outputs by pulsed signals
The following switch-on condition applies for the safety outputs FO1A and FO1B
(see also System status table and section Typical system times):
Ì Safety guard closed
Ì Both safety inputs FI1A and FI1B must be switched on.
The CES system consists of the following components: coded actuator (transponder) and switch.
Every EUCHNER actuator supplied has an electronic coding (unique coding) that is
read by the read head. Only if a correct coding is detected does the system accept
the actuator. The code in an actuator cannot be reprogrammed.
Unlike systems with unique code detection, on the CES-I-AP-M-C04 a specific code
is not polled but instead it is only checked whether the actuator is of a type that can
be detected by the system (multicode detection). There is no exact comparison of
the actuator code with the code defined in the safety switch (unique code detection).
The safety switch is fastened to the fixed part of the safety guard.
The actuator attached to the movable part of the safety guard is moved towards
the read head fitted in the safety switch by closing the door. When the switch-on
distance is reached, power is supplied to the actuator by the read head by induction and data can be transferred.
If a permissible code is detected, the safety outputs are released. Independent of
the safety outputs, monitoring output OD switches on as soon as the actuator is
in the operating distance.
Due to the combination of dynamic polling of the actuator and the redundant,
diverse design of the safety electronics with the two feedback safety outputs, the
safety switch will enter the safe state with every detectable fault.
When the safety guard is opened, the safety outputs switch off the safety circuit
and the monitoring output OD is switched off. The state of the safety outputs is
monitored internally by two microprocessors.
If faults are detected, the safety circuit is switched off and the DIA LED illuminates.
In case of devices with a monitoring output OI, the output is switched on.
The safety switch has a redundant circuit design with self-monitoring. This means
that the safety system is still effective even if a component fails.
6
Operating Instructions Safety Switch CES-I-AR-M-C04
The system is designed so that failures will not result in the loss of the safety function. The occurrence of failures is detected by cyclic self-monitoring at the latest
on the next demand to switch the safety outputs (e.g. on starting).
If the safety door with the actuator should settle over time, the actuator can drift
out of the switch operating distance. The device recognizes this situation and
indicates that the actuator is in the limit range. This allows the safety door to be
readjusted in time.

Electrical connection
The following connection options are available:
Ì Separate operation
Ì Series connection with Y-distributors from EUCHNER (only with M12 plug con-
nector)
Ì Series connection, e.g. with wiring in the control cabinet
Ì Operation on an AR evaluation unit.
Warning!
In case of an error, loss of the safety function through incorrect connection.
Ì To ensure safety, both safety outputs (FO1A and FO1B) must always be
evaluated.
Ì The monitoring output OD must not be used as a safety output.
Ì Lay 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.
Ì Do 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 last up to 1 ms.
Depending on the inertia of the connected device (control system, relay,
etc.), this can lead to short switching processes.
Ì The 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.
Ì All the electrical connections must either be isolated from the mains supply
by a safety transformer according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures (PELV).
Ì For 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.
Ì For use and operation as per the requirements*, a connection cable
listed under the UL category code CYJV2 must be used. The connection
cables from EUCHNER meet these requirements. The same requirement applies to the safety outputs.
Ì All electrical outputs must have an adequate protective circuit for inductive
loads. The outputs must be protected with a free-wheeling diode for this purpose. RC interference suppression units must not be used.
Ì Power devices which are a powerful source of interference must be installed
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.
* Note on the scope of the UL approval: Only for applications as per NFPA 79 (Industrial Machinery)
The devices have been tested as per the requirements of UL508 (protection against electric shock and fire).

Operating Instructions Safety Switch CES-I-AR-M-C04
Caution!
Ì In order to avoid EMC interference, the physical environmental and operating
conditions at the installation site of the device must comply with the requirements 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.
Safety in case of faults
Caution!
Ì The operating voltage U
is reverse polarity protected.

Ì The contacts FO1A/FO1B are short circuit-proof.
Ì A short circuit between FO1A and FO1B is detected by the switch.
Ì A 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 current
required for the outputs. The following rules apply:

Requirements for connection cables
Risk of damage to equipment or malfunctions as a result of incorrect connection cables.
Ì Use connection components and connection cables from EUCHNER
Ì On 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.
Ì The connection cable must not be longer than 200 m in total.

Here: 6 switches.
2. In column I
(possible output current per channel FO1A/FO1B), find a current

Connection of a single CES-I-AR
If a single CES-I-AR is used, connect the switch as shown in Figure 3. The OD output
can also be connected here to a control system as a monitoring output.
The switch 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 RST input must be connected to 0 V
if it is not used.
Important!
The subsystem CES-I-AR complies with PL e in accordance with EN 13849-1. To
integrate the subsystem in a category 3 or 4 structure, it is necessary to monitor
the downstream load (the feedback loop must be monitored).
These examples show only an excerpt that is relevant for connection of the CES
system. The example illustrated here does not show complete system planning.

Connection of several CES-I-AR in a switch chain
Important!
Ì An AR switch chain may contain a maximum of 20 safety switches.
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
PFH
of 2.47x10-8/h.
d
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.
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.
The series connection is shown here based on the example of the version with plug
connectors M12. The switches are connected one behind the other with the aid
of pre-assembled connection cables 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 cannot, however, detect which safety door is open or
on which switch a fault has occurred with this connection technology. A special AR
evaluation unit is required for this purpose (see section Information on operation
on an AR evaluation unit).
can be
d
The series connection can also be realized via additional terminals in a control
cabinet.
The safety outputs are permanently assigned to the respective safety inputs of the
downstream switch. FO1A must be routed to FI1A and FO1B to FI1B. If the connections are interchanged (e.g. FO1A to FI1B), the unit will switch to the fault state)
Always use the RST input in series connections. All switches in a chain can be
reset at the same time with this reset input. To do this, a voltage of 24 V must be
applied to the RST input for at least 3 seconds. If input RST is not used in your
application, it should be connected to 0 V.
Note the following on this aspect:
Ì A common signal must be used for all switches in the chain. This can be a
changeover switch or the output of a control system. A button is not suitable
because Reset must always be connected to GND during operation (see switch
S1 in Figure 5).
Ì Reset must always be performed simultaneously for all switches of the chain.
Information on operation on an AR evaluation unit
The devices can be operated on an AR evaluation unit. Please refer to the operating
instructions for the relevant AR evaluation unit for more information.

Notes on operation with safe control systems
Please observe the following requirements for connection to safe control systems:
Ì Use a common power supply for the control system and the connected safety
switches.
Ì A pulsed power supply must not be used for UB. Tap the supply voltage direct-
ly from the power supply unit. If the supply voltage is connected to a terminal
of a safe control system, this output must provide sufficient electrical current.
Ì Always connect inputs FI1A and FI1B directly to a power supply unit or to
outputs FO1A and FO1B of another EUCHNER AR device (series connection).
Pulsed signals must not be present at inputs FI1A and FI1B.
Ì Outputs FO1A and FO1B can be connected to the safe inputs of a control sys-
tem. Prerequisite: The input must be suitable for pulsed safety signals (OSSD
signals, e.g. from light curtains). The control system must tolerate clock pulses on the input signals. This normally can be set up by parameter assignment
in the control system. Observe the notes of the control system manufacturer.
For the pulse duration of your safety switch, please refer to the section “Typi-
cal system times” on page 23.
A detailed example of connecting and setting the parameters of the control system
is available for many devices at www.euchner.de in the area Download » Applications
» CES. The features of the respective device are dealt with there in greater detail.

Initial setup
1. Apply operating voltage to the safety switch.
¨ The green LED flashes quickly (approx. 5 Hz).
A self-test is performed during this time (8 s). After this, the green LED flashes cyclically one time and signals that it is in standby state.
Normal operation: Door closed
- Power Up
- Door open
- Actuator in the limit range
(refer to the status table for further signal functions)
- Internal electronics fault
- Fault at the inputs/outputs
Warning!
2. Move actuator to the read head (observe distance < S
).
ao
¨ The green LED illuminates continuously and indicates the detection of the
actuator.
If the green LED is flashing quickly, the actuator is in the limit range. In this
case the safety guard must be re-adjusted such that the actuator is completely in the read area.
Functional check
After installation and any fault, the safety function must be fully checked. Proceed
as follows:
Danger of fatal injury as a result of faults in installation and functional check.
Ì Before carrying out the functional check, make sure that there are no per-
sons in the danger area.
Ì Observe the valid accident prevention regulations.
1. Switch on operating voltage.
Ì The safety switch 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.
Ì The machine must not start automatically.
Ì The green STATE LED illuminates continuously.
3. Enable operation in the control system.
4. Open the safety guard.
Ì The machine must switch off and it must not be possible to start it as long as
the safety guard is open.
Ì The green STATE LED flashes at regular intervals.
Repeat steps 2-4 for each safety guard.

After the cause has been remedied, faults can generally be reset by opening
and closing the door. If the fault is still displayed afterward, briefly interrupt the
power supply. Please contact the manufacturer if the fault could not be reset after
restarting.
If you do not find the displayed device status in the System status table, this indicates an internal device fault. In this case, you should contact the manufacturer.

Operating Instructions Safety Switch CES-I-AR-M-C04
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.
Switch-on time of safety outputs: The max. reaction time from the moment when
the actuator is at the operating distance (safety door closed) to the moment when
the safety outputs switch on T
Simultaneity monitoring, safety inputs FI1A/FI1B: If the safety inputs have
different switching states for longer than 150 ms, the safety outputs FO1A/FO1B
will be switched off.
Risk time according to EN 60947-5-3: If an actuator moves outside the operating distance, the safety outputs FO1A and FO1B are deactivated after a maximum
of 260 ms. This value applies to a single switch. For each additional switch in a
chain the risk time increases by 5 ms.
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.
Test pulses at the safety outputs: The device generates its own clock signal on
the output lines FO1A/FO1B. A downstream control system must tolerate these
test pulses, which may last up to 1 ms.
is 300 ms (400 ms for switch chains).
on
This can usually be set up in the control systems by parameter assignment. If
parameter assignment is not possible for your control system or if shorter test
pulses are required, please contact our support organization.
The test pulses are also output when the safety outputs are switched off.
